Typically, the size of the screen of the display unit 12 is about 5 to 6 inches, but the size is not limited to this. A terminal having a large screen display unit 12 of about 9 inches or more is generally called a tablet terminal.

FIG. 2 is a block diagram showing an outline of the internal configuration of the mobile terminal device 10. The mobile terminal device 10 includes a display unit 12, a touch panel 13, a communication unit 14, a storage unit 15, a sensor 16, a hard button 17, and a control unit 20. These components are capable of transmitting and receiving data or signals through the bus to each other.

A camera, a speaker, an LED (Light Emitting Diode), and the like are arranged on the outer surface of the mobile terminal device 10, but for convenience, the illustration of such members is omitted in FIG.

The display unit 12 is composed of a liquid crystal display (LCD: Liquid Crystal Display), an organic EL (OLED: Organic Light-Emitting Diode), and the like.

The touch panel 13 is a touch panel of a so-called resistance film method, a capacitance method, or the like. The touch panel 13 is arranged on the screen of the display unit 12, and detects the contact of a finger or the like with the screen of the display unit 12 together with the contact position. When the touch panel 13 detects contact with a finger or the like, the touch panel 13 outputs a detection signal indicating the coordinates of the contact position to the control unit 21 or the like of the control unit 20. Therefore, the touch panel 13 serves as an operation unit for inputting a user operation on the screen of the display unit 12. As a result, the display unit 12 can display objects such as various buttons at arbitrary positions on the screen and detect on the touch panel 13 whether or not the buttons have been touch-operated.

Further, the mobile terminal device 10 may include a hard key in addition to the touch panel 13 as an operation unit into which a user operation is input.

The communication unit 14 is a wireless communication interface that performs wireless communication with a wireless base station or an external device. Wi-Fi (registered trademark), Bluetooth (registered trademark), and the like can be used as the wireless communication method. Further, the communication unit 14 can perform carrier communication by 3G communication, LTE (Long Term Evolution), or the like.

The storage unit 15 is composed of, for example, a large-capacity SSD (Solid State Drive), an HDD (Hard Disk Drive), or the like, and stores various data and programs. Further, the storage unit 15 stores temporary data or the like used by the control unit 20 when the application is executed.

The sensor 16 detects the inclination of the housing 11, and is, for example, an acceleration sensor, a gyro sensor, or the like.

The control unit 20 is composed of a processor, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The processor is a CPU (Central Processing Unit), an MPU, an ASIC, or the like. The control unit 20 has a control unit 21, a display control unit 22, an operation area determination unit 23, a specific tilt determination unit 24, and a control program stored in the ROM or the storage unit 15 executed by the processor. It functions as a display change unit 25, an area comparison unit 26, a display return unit 27, a determination unit 28, and a first specific unit 29. It should be noted that each of the above-mentioned components of the control unit 20 may be configured by a hardware circuit, regardless of the operation based on the above-mentioned control program.

The control unit 21 controls the overall operation of the mobile terminal device 10. Further, the control unit 21 is connected to a display unit 12, a touch panel 13, a communication unit 14, a storage unit 15, a sensor 16 and the like, and controls the operation of each of the above components, and signals or signals between the components. Send and receive data. In particular, the control unit 21 executes an application program (application) installed in the mobile terminal device 10 to control the screen display on the display unit 12, and operates in response to a touch operation on the screen of the display unit 12. .. For example, when the control unit 21 executes the remote operation application of the multifunction device, the copy, print, scan, and facsimile of the multifunction device are performed through the GUI (Graphical User Interface) displayed on the screen of the display unit 12 of the mobile terminal device 10. Each function of can be operated remotely.

The display control unit 22 is placed at a plurality of predetermined arrangement positions on the screen of the display unit 12 (for example, in FIG. 3A, two rows and four columns are arranged vertically and four horizontally). A plurality of objects (8 objects OJ of "A" to "H") that can be selected by touch operation by the user are displayed respectively.

The operation area determination unit 23 is displayed on the screen of the display unit 12 from the locus of the touch position of the operation finger (for example, the thumb) of the display unit 12 with respect to the screen of the display unit 12 while the user is holding the housing 11 with one hand. Determine the operation area that the operation finger can reach. Specifically, when the operation area determination unit 23 grips the housing 11 with the right hand as shown in FIG. 3A, the operation area determination unit 23 determines the locus of the touch position by the operation finger U of the right hand with respect to the screen of the display unit 12. It is specified by the detection signal by the touch panel 13, the locus of the touch position is specified as the limit line BL on the screen, and the display unit 12 other than the limit line BL in each divided area obtained by dividing the screen of the display unit 12 by the limit line BL. The divided area where the contact point T1 touching the screen of is present is determined as the operation area AS. As a result, the operation area AS can be determined only by the operation finger U of one hand that grips the housing 11, and the operability is excellent.

Further, when at least one of the start point and the end point of the locus of the touch position does not reach the end position of the screen of the display unit 12, the operation area determination unit 23 sets the locus of the touch position in the direction of the locus. The limit line BL is specified by extending along the line to the end position of the screen of the display unit 12. As a result, even if the end of the locus of the touch position does not reach the end position of the screen of the display unit 12, the locus of the touch position can be supplemented, and the operation area AS can be appropriately determined. , Excellent operability.

The storage unit 15 includes an operation area storage unit 151 that stores area data indicating the operation area AS determined by the operation area determination unit 23, and a usage frequency storage unit 152 that stores the usage frequency of each of a plurality of objects. As the frequency of use, the control unit 21 stores, for example, the integrated number of touch operations for each object in the frequency of use storage unit 152 for a period from the latest day to a predetermined number of past days. The frequency of use may be the time of use, the number of times of use, or the like.

In the specific tilt determination unit 24, after the area data is stored in the operation area storage unit 151, the inclination of the housing 11 detected by the sensor 16 is tilted toward the operation finger U side of the one hand (specific inclination). For example, in the example shown in the upper left of FIG. 5, it is determined whether or not it is laterally inclined to the right hand side). The specific inclination is an inclination of a predetermined angle (for example, 30 degrees) or more from the reference posture of the housing 11 described later. This makes it possible to prevent erroneous determination as a specific inclination due to an inclination smaller than the specific inclination.

When the display change unit 25 determines that the specific inclination is determined by the specific inclination determination unit 24, the display change unit 25 sets a plurality of changed positions in the operation area AS, and sets a plurality of objects at the set plurality of changed positions. Move and display each. As shown in the lower left or lower right of FIG. 5, the display changing unit 25 sets a plurality of changed positions in the operation area AS, and eight "A" to "H" are set in the plurality of changed positions. Display each object OJ of.

As shown in the upper left of FIG. 5, the area comparison unit 26 includes the area of the operation area AS on the screen of the display unit 12 and a plurality of objects (“A” to Compare with the total area which is the area of the area TA including the eight objects OJ) of "H". Specifically, the control unit 21 has the total number of pixels of the screen of the display unit 12 stored in the storage unit 15 in advance and the area data stored in the operation area storage unit 151 (each of the pixels on the limit line BL). The area of the operation area AS is calculated from the relationship with the coordinate data). For example, the area of the operation area AS is calculated by counting the number of pixels in the divided area where the contact point T1 exists among the divided areas in which the screen of the display unit 12 is divided into two by the limit line BL. Further, since the control unit 21 calculates the display area of each object on the screen of the display unit 12 and the gap area between the objects in pixel units, the display area of all the objects and the gap area between the objects can be calculated. The total area is calculated by integrating. The area comparison unit 26 compares the area of the operation area AS with the total area.

When the comparison result of the area comparison unit 26 is larger than the area of the operation area AS, the display change unit 25 accommodates a plurality of objects in the operation area AS as shown in the lower left of FIG. In this way, after reducing each of the plurality of objects, they are moved to a plurality of changed positions and displayed, and when the comparison result of the area comparison unit 26 is smaller than the area of the operation area AS, the figure is shown in the figure. As shown in the lower right of 5, a plurality of objects are moved to a plurality of changed positions and displayed without being reduced. As a result, a plurality of objects can be appropriately displayed according to the size of the operation area AS set by the user.

As shown in the upper left or upper right of FIG. 6, the display return unit 27 is detected by the sensor 16 in a state where a plurality of objects are displayed at a plurality of changed positions in the operation area AS by the display change unit 25. It is specified that the tilt of the housing 11 is a return tilt tilted toward the side opposite to the operation finger U of the one hand (for example, in FIG. 6, a lateral tilt toward the side opposite to the operation finger U side of the right hand). An operation (for example, a flick operation) in which the operation finger U touching the operation area AS of the screen of the display unit 12 is slid toward the plurality of predetermined arrangement positions when the determination is made by the tilt determination unit 24. Is detected by the touch panel 13, the plurality of objects displayed at the plurality of changed positions in the operation area AS are returned to the plurality of predetermined arrangement positions as shown in the lower center of FIG. To display. As a result, the user can return a plurality of objects to the original arrangement by simply tilting the object to the side opposite to the operation finger U of one hand, which is excellent in operability.

The determination unit 28 determines whether or not at least one of the plurality of predetermined arrangement positions is included in the operation area AS determined by the operation area determination unit 23. For example, in the example shown in the upper left of FIG. 7, the determination unit 28 has at least one of the 16 object OJs “A” to “P” arranged in the operation area AS (“K”, It is determined that the arrangement positions of the four objects OJ of "L", "O", and "P") are included.

When the determination unit 28 determines that the placement position of the object is not included in the operation area AS, the display change unit 25 determines that the specific inclination is the specific inclination by the specific inclination determination unit 24, and the lower left of FIG. Alternatively, as shown in the lower right, a plurality of objects are moved and displayed at a plurality of changed positions in the operation area AS indicated by the area data stored in the operation area storage unit 151. Further, when the display changing unit 25 determines that the operation area AS includes the at least one arrangement position, the display changing unit 25 determines that the specific inclination determination unit 24 has a specific inclination. As shown in the lower left or lower right of 7, the object related to the at least one arrangement position and the object outside the operation area AS are interchanged and displayed. As a result, even if the object OJ is included in the operation area AS set by the user, that is, even if the operation area AS is not a blank area, the object OJ in the operation area AS and the object OJ outside the operation area AS And can be replaced and displayed.

When the determination unit 28 determines that some of the plurality of objects are arranged in the operation area AS, the display change unit 25 determines that the display change unit 25 has a specific inclination by the specific inclination determination unit 24. Then, the part of the objects and the objects within the predetermined range located on the upstream side in the inclination direction of the specific inclination outside the operation area AS are exchanged and displayed. As a result, the tilting direction of the specific tilt can be matched with the direction in which the moving source object moves to the operation area AS, and the movement of the object linked to the operation of the specific tilt by the user can be realized.

Further, the specific tilt determination unit 24 has a first specific tilt (horizontal tilt shown in FIG. 10A, which will be described later) in which the screen of the display unit 12 is tilted toward the lateral side of the screen as a specific tilt. The second specific tilt (diagonal tilt shown in FIG. 10B) tilted toward the diagonal direction of the screen and the third specific tilt tilted toward the vertical side direction of the screen (FIG. 10C). (Vertical tilt shown in)). When the determination unit 28 determines that some of the plurality of objects are arranged in the operation area AS, the display change unit 25 determines that the display change unit 25 has the first specific inclination by the specific inclination determination unit 24. Then, as shown in FIG. 10A, the part of the object and the lateral end side range as a predetermined range located on the upstream side in the inclination direction of the first specific inclination outside the operation area AS. When the object in the inside is replaced and displayed and the specific inclination determination unit 24 determines that the second specific inclination is obtained, as shown in FIG. 10B, the part of the object and the outside of the operation area AS are displayed. The object within the diagonal end side range as a predetermined range located on the upstream side in the inclination direction of the second specific inclination is replaced and displayed, and the specific inclination determination unit 24 determines that the third specific inclination is obtained. Then, as shown in FIG. 10 (C), the part of the object and the vertical end side range as a predetermined range located on the upstream side in the inclination direction of the third specific inclination outside the operation area AS. It is displayed by exchanging with the object in. As a result, the target object can be moved to the operation area AS simply by selecting the first to third specific tilts (horizontal tilt, diagonal tilt, vertical tilt) according to the placement position of the object to be moved to the operation area AS. It can be made to operate and has excellent operability.

The first specific unit 29 is among the objects that are used the least frequently among the above-mentioned objects and the objects within a predetermined range located on the upstream side in the inclination direction of the specific inclination outside the operation area AS. The object with the highest frequency of use is specified by using the frequency of use for each of a plurality of objects stored in the frequency of use storage unit 152. When the determination unit 28 determines that some of the objects among the plurality of objects are arranged in the operation area AS, the display change unit 25 determines that the display change unit 25 has a specific inclination by the specific inclination determination unit 24. , And the object that is used most frequently and the object that is used most frequently are displayed interchangeably. As a result, the least frequently used object in the operation area AS and the most frequently used object outside the operation area AS are displayed interchangeably, so that the object most likely to be used by the user is displayed in the operation area. It can be moved to AS and has excellent operability.

In addition to the above components, the mobile terminal device 10 is equipped with a speaker, a microphone, an LED, a vibrator, and the like, but for convenience, the illustration of such components is omitted in FIG.

As described above, in the mobile terminal device 10, various buttons and other objects (screen images) are displayed on the screen of the display unit 12 by the activated application. When the mobile terminal device 10 is operated with one hand, the screen image is operated by moving the free operating finger U that supports the mobile terminal device 10 with a finger other than the operating finger U (thumb). At this time, in the mobile terminal device 10 provided with the display unit 12 of a large screen of about 5 inches or more, the operation finger U is the edge of the screen of the display unit 12 as shown in FIGS. 3 (A) and 3 (B). May not reach. Objects (buttons) arranged at positions that cannot be reached by such an operating finger U need to be operated using the other hand. In response to this problem, in the first embodiment, as shown in FIG. 5, the operating finger is only slightly tilted toward the operating finger U (thumb) side of one hand holding the mobile terminal device 10. The object OJ is moved to the operation area AS where U can reach, and even if the screen size of the display unit 12 is relatively large, it is possible to operate with one hand.

Next, the object movement display process in the mobile terminal device 10 of the first embodiment will be described with reference to the flowchart shown in FIG. FIG. 4 is a flowchart showing an example of the object movement display process of the first embodiment.

When the power of the mobile terminal device 10 is turned on, the mobile terminal device 10 is activated (S11). Then, the display control unit 22 displays a plurality of objects that can be selected by a touch operation by the user at a plurality of predetermined arrangement positions on the screen of the display unit 12 (S12: display control step). For example, as shown in FIGS. 3 (A) and 3 (B), “A” is placed at the arrangement position of 2 rows and 4 columns with 2 vertically and 4 horizontally on the upper side of the screen of the display unit 12. -Eight objects OJ of "H" are displayed. As shown in FIG. 3A, when the mobile terminal device 10 is held by the right hand, eight objects OJ are arranged outside the operation area AS where the operation finger U of the right hand can reach, so that the right hand has eight objects OJ. The object OJ cannot be touch-operated with the operation finger U. Further, as shown in FIG. 3B, even when the mobile terminal device 10 is held by the left hand, the object OJ cannot be touch-operated with the operation finger U of the left hand as in the case of the right hand.

The control unit 21 determines whether or not there is an instruction in the operation area AS (S13). For example, if there is a designated operation (for example, double tap) for the hard button 17, the control unit 21 determines that there is an instruction in the operation area AS (YES in S13). When the control unit 21 determines that the operation area AS is instructed (YES in S13), the operation area determination unit 23 determines that the operation finger U with respect to the screen of the display unit 12 while the user is holding the housing 11 with one hand. The operation area AS to which the operation finger U reaches is determined on the screen of the display unit 12 from the locus of the touch position by (S14: operation area determination step).

Specifically, as shown in FIG. 3A, the operation area determination unit 23 touches the screen of the display unit 12 with the operation finger U of the right hand while the user is holding the housing 11 with the right hand. The limit line BL on the screen is specified from the locus of the position, and there is a contact point T1 that touches the screen of the display unit 12 in addition to the limit line BL in each divided region in which the screen of the display unit 12 is divided into two by the limit line BL. The divided area is determined as the operation area AS. For example, when the operation finger U of the right hand is used to touch the screen in an arc shape, the base portion of the operation finger U can be easily touched discretely on the screen, and at least one of these contact points T1 is a touch panel. Detected by 13. If the contact point T1 is not detected, the control unit 21 urges the operation finger U to touch an arbitrary position on the screen closer to the operation finger U than the limit line BL. The promotion display is displayed on the screen of the display unit 12. When the user who sees the promotion display touches the position on the screen, the contact point T1 is detected by the touch panel 13. The operation area determination unit 23 determines the operation area AS by the limit line BL and the contact point T1.

The control unit 21 stores the area data indicating the operation area AS determined by the operation area determination unit 23 in the operation area storage unit 151 (S15: operation area storage step).

In the specific tilt determination unit 24, after the area data is stored in the operation area storage unit 151, the inclination of the housing 11 detected by the sensor 16 is the specific inclination tilted toward the operation finger side of the one hand. It is determined whether or not (S16: specific inclination determination step). When the specific tilt determination unit 24 determines that the inclination of the housing 11 detected by the sensor 16 is the specific inclination (YES in S16), the determination unit 28 moves into the operation area AS determined by the operation area determination unit 23. It is determined whether or not at least one of the plurality of predetermined placement positions is included (S17). For example, when the object is not located in the operation area AS as shown in FIG. 3, the determination unit 28 determines that the arrangement position is not included (NO in S17), and as shown in FIG. When the object is located in the operation area AS, it is determined that the placement position is included (YES in S17).

When the determination unit 28 determines that the placement position of the object is not included in the operation area AS (NO in S17), the area comparison unit 26 determines the area of the operation area AS on the screen of the display unit 12 in advance. Compare with the total area including the plurality of objects arranged at the plurality of arrangement positions (S18).

When the comparison result of the area comparison unit 26 is larger than the area of the operation area AS (YES in S18), the display change unit 25 has all the objects in the operation area as shown in the lower left of FIG. After reducing each object so that it fits in the AS, it is moved to a plurality of changed positions and displayed (S19: display change step). On the other hand, when the comparison result of the area comparison unit 26 is smaller than the area of the operation area AS (NO in S18), the display change unit 25 displays the object as shown in the lower right of FIG. It is moved to the position after the change without reduction and displayed (S20: display change step).

That is, when the display changing unit 25 determines that the specific tilt is determined by the specific tilt determining unit 24, the display changing unit 25 sets a plurality of changed positions in the operation area AS, and a plurality of the set changed positions are set. Move and display each object.

As shown in the upper left or upper right of FIG. 6, the display return unit 27 is detected by the sensor 16 in a state where a plurality of objects are displayed at a plurality of changed positions in the operation area AS by the display change unit 25. When the specific tilt determination unit 24 determines that the tilt of the housing 11 is a return tilt tilted toward the side opposite to the operation finger of the one hand, or the operation area of the screen of the display unit 12. When the touch panel 13 detects an operation (for example, a flick operation) of sliding the operation finger touching the inside of the AS toward the plurality of predetermined arrangement positions, the operation area is as shown in the lower center of FIG. The plurality of objects displayed at the plurality of changed positions in the AS are returned to the plurality of predetermined arrangement positions and displayed.

On the other hand, when the determination unit 28 determines that the arrangement position of at least one object is included in the operation area AS (YES in S17), the specific inclination determination unit 24 determines that the specific inclination is displayed. The change unit 25 replaces and displays the object related to the at least one arrangement position and the object outside the operation area AS (S21: display change step). As shown in the lower right of FIG. 7, the display changing unit 25 includes some objects (four objects OJ of “K”, “L”, “O”, and “P”) and the operation area outside the AS. (4 objects OJ of "A", "B", "E", and "F") within a predetermined range located on the upstream side in the inclination direction of the specific inclination are displayed interchangeably. .. In addition, instead of replacing a plurality of objects in the operation area AS at the same time as described above, the display changing unit 25 may be replaced with some objects (object OJ of "P"), for example, as shown in the lower left of FIG. , Objects within a predetermined range (object OJ of "A") located on the upstream side in the inclination direction of the specific inclination outside the operation area AS may be replaced and displayed.

Here, the specific inclination determination of the mobile terminal device 10 (housing 11) determined by the specific inclination determination unit 24 will be described with reference to FIGS. 8 and 9. As shown in FIG. 8A, the sensor 16 acquires the three-axis coordinate values of the four points C1 to C4 of the lower right corner portion, the upper right corner portion, the upper left corner portion, and the lower left corner portion of the mobile terminal device 10, and the specific inclination is obtained. As shown in FIG. 8B, the determination unit 24 sets the posture in which the user is holding the housing 11 with one hand as the reference posture, and the inclination from the reference posture is set to FIGS. 9A to 9C. ), It is determined whether or not the inclination is specific.

(1) First, the specific tilt determination unit 24 sets the tilt angle of the mobile terminal device 10 when the user determines the operation area AS with the operation finger of one hand as the reference posture. That is, the specific tilt determination unit 24 sets the reference tilt coordinates. For example, the specific tilt determination unit 24 projects the three-axis coordinate values of the four points C1 to C4 of the housing 11 onto the XY-axis plane of the three-axis coordinate system, and sets this state as the reference posture.

(2) The specific tilt determination unit 24 detects in which direction the tilt is further from the state of the reference posture by using the three-axis coordinate values of the four points acquired by the sensor 16. For example, as shown in FIG. 9, the specific tilt determination unit 24 has the three-axis coordinate values of the four points C1 to C4 projected on the XY-axis plane and the four points C1 when the housing 11 is tilted. The inclination vector for each coordinate is detected from the three-axis coordinate values of to C4, and the direction of inclination is identified by the magnitude of the inclination vector of each coordinate. For example, in the case of the lateral inclination shown in FIG. 9A, the inclination vectors of the points C3 and C4 are larger than those of the points C1 and C2. As a result, it is detected that the tilt is horizontal. If the slope vector value is equal to or greater than a predetermined value, it is treated as detection, and if it is less than a predetermined value, it is not detected as an error.

Further, as shown in FIG. 10A, when the specific tilt determination unit 24 determines that the screen of the display unit 12 is the first specific tilt (horizontal tilt) tilted toward the horizontal side direction of the screen, the display is displayed. The change unit 25 includes some objects (four objects OJ of "K", "L", "O" and "P") and the upstream side in the inclination direction of the first specific inclination outside the operation area AS. The objects (four objects OJ of "A", "E", "I", and "M") in the horizontal end side range as a predetermined range located in are replaced and displayed.

Further, as shown in FIG. 10B, when the specific tilt determination unit 24 determines that the second specific tilt (diagonal tilt) is tilted toward the diagonal direction of the screen, the display change unit 25 is partially displayed. (4 objects OJ of "K", "L", "O" and "P") and a predetermined object located on the upstream side in the inclination direction of the second specific inclination outside the operation area AS. Objects within the diagonal end side range as a range (four objects OJ of "A", "B", "E", and "F") are exchanged and displayed.

Further, as shown in FIG. 10C, when the specific tilt determination unit 24 determines that the third specific tilt (vertical tilt) is tilted toward the vertical side direction of the screen, the display change unit 25 is determined to be one. The objects of the part (four objects OJ of "K", "L", "O" and "P") and the predetermined objects located on the upstream side in the inclination direction of the third specific inclination outside the operation area AS. The objects (4 objects OJ of "A", "B", "C", and "D") in the vertical end side range as the range are displayed interchangeably.

Returning to FIG. 4, when it is determined that there is no instruction in the operation area AS (NO in S13), the control unit 21 ends this process after S19, S20, or S21. When the touch panel 13 detects the touch operation of the object moved in the operation area AS, the control unit 21 performs the operation control by the object to which the touch operation is performed. That is, the application related to the touch-operated object is started.

As described above, according to the first embodiment, in a state where the user holds the mobile terminal device 10 with one hand, the operation finger U is generated from the locus of the touch position by the operation finger U of the one hand with respect to the screen of the display unit 12. Since the reachable operation area AS is determined, an appropriate operation area AS can be set according to the characteristics of the user. For example, an appropriate operation area AS can be set even for a user with a small hand such as a child or a woman. Then, after the operation area AS is determined, the object OJ on the screen of the display unit 12 is moved to the operation area AS and displayed by simply tilting the mobile terminal device 10 toward the operation finger U side. The object OJ in the operation area AS can be touch-operated with. For example, in the case of a large mobile terminal device, even in the case of a mobile terminal device equipped with a protective case, the object OJ on the screen of the display unit 12 can be displayed by simply tilting the mobile terminal device 10 toward the operation finger U side. Since the object OJ is moved to the operation area AS and displayed, the object OJ can be reliably moved to the position where the operation finger U can reach. This makes it possible to improve the operability of the mobile terminal device 10 with one hand.

Next, the mobile terminal device 10 according to the second embodiment will be described with reference to FIGS. 11 to 14. FIG. 11 is a block diagram showing the configuration of the mobile terminal device 10 according to the second embodiment. Of the configurations shown in FIG. 11, the same configurations as those shown in FIG. 2 of the above-mentioned first embodiment are designated by the same reference numerals and the description thereof will be omitted.

The control unit 20 shown in FIG. 11 includes a blank area forming unit 31, a leader line display control unit 32, a numerical value determination unit 33, a distance determination unit 34, an individual return unit 35, a second specific unit 36, and an irregularity. A moving unit 37 is provided.

When the blank area forming unit 31 is determined by the specific inclination determination unit 24 to have a specific inclination, and the determination unit 28 determines that the operation area AS includes at least one arrangement position, FIG. 13 ( As shown in B), a blank area BA is formed in the operation area AS.

The leader line display control unit 32 has a plurality of leader lines (FIG. 13) from all objects outside the operation area AS (12 objects OJ of "A" to "N" in FIG. 13 (A)) toward the blank area BA. In 13 (C), two leader lines L1 and ten leader lines L2) are displayed.

The display changing unit 25 touches the leader line of one of the plurality of leader lines (the leader line L1 of the object OJ of "A" in FIG. 13 (C)) with the operation finger U of the right hand, and the blank area BA. When the touch panel 13 detects an operation of moving toward the object (hand-pulling operation), the object connected to the one leader line (in FIG. 13D, the object OJ of "A") is moved to the blank area BA. Move to and display. This makes it possible to provide a new and interesting movement operation called a hand-pulling operation.

The numerical value determination unit 33 uses the frequency of use for each of the plurality of objects stored in the frequency of use storage unit 152, and the leader lines (two leader lines L1 and ten leader lines L2 in FIG. 13C) are It is determined whether or not the frequency of use of the connected objects (12 objects OJ of "A" to "N" in FIG. 13A) is equal to or higher than a predetermined numerical value.

In the leader line display control unit 32, the frequency of use of the object to which the leader line is connected (12 objects OJ of "A" to "N" in FIG. 13A) is equal to or higher than the predetermined value. Is determined by the numerical value determination unit 33, the leader line (two leader lines L1 in FIG. 13C) is displayed in the first display mode (for example, a thick line), and is less than the predetermined value. When it is determined by the numerical value determination unit 33, the leader line (10 leader lines L2 in FIG. 13C) is displayed in a second display mode (for example, a thin line) different from the first display mode. Display. As a result, the display mode of the leader line differs depending on the frequency of use of the object, so that the user can pull the object in consideration of the frequency of use.

In the above, the display mode of the leader line is changed according to the frequency of use of the object OJ, but the display mode of the leader line may be changed according to the distance from the object to the blank area BA. .. For example, the storage unit 15 includes a distance storage unit 153 that stores the distance to the blank area BA for each of a plurality of objects. The distance determination unit 34 connects leader lines using the distances for each of a plurality of objects stored by the distance storage unit 153 (12 objects OJs "A" to "N" in FIG. 13A). It is determined whether or not the distance of the object is equal to or greater than a predetermined reference distance. When the distance determination unit 34 determines that the distance of the object to which the leader line is connected is equal to or greater than the reference distance, the leader line display control unit 32 displays the leader line in the first display mode (for example, a thick line). When the distance determination unit 34 determines that the distance is less than the reference distance, the leader line is displayed in a second display mode (for example, a thin line) different from the first display mode. As a result, the display mode of the leader line differs depending on the distance from the object to the blank area BA, so that it becomes easy for the user to identify the object to be drawn.

The individual return unit 35 is shown in FIG. 14 (B) when the object connected to the leader line is moved to the blank area BA and displayed by the display change unit 25 as shown in FIG. 14 (A). When the cut operation CT, which is a touch operation that crosses one leader line (leader line L1 of the object OJ of "C") with the operation finger U, is detected by the touch panel 13, it is moved to the blank area BA and displayed. The existing object (in FIG. 14C, the object OJ of "C") is returned to the original arrangement position outside the operation area AS and displayed. As a result, the operation of pulling the object and the cut operation CT for the leader line can be performed separately, and the operation of moving the object can be made easy to understand.

In the above, as shown in FIG. 14 (C), the object OJ whose leader line is cut is moved out of the operation area AS, but as shown in FIG. 14 (D), the infrequently used object is used. It may be moved out of the operation area AS. For example, the second specifying unit 36 identifies the object with the lowest usage frequency in the operation area AS by using the usage frequency for each of the plurality of objects stored in the usage frequency storage unit 152. When the object connected to the leader line is moved to the blank area BA, the leader line display control unit 32 displays the one leader line L1 in the third display mode (for example, the red line), and the second specific unit The leader line L2 of the object with the lowest frequency of use in the operation area AS specified by 36 is displayed in a fourth display mode (for example, a black line) different from the third display mode.

When the touch panel 13 detects the cut operation CT, which is a touch operation in which the leader line display control unit 32 crosses one leader line L1 displayed in the third display mode with the operation finger of the one hand. , The object OJ that is the least frequently used in the operation area AS connected to the leader line L2 in the fourth display mode, instead of the object OJ connected to the leader line L1 in the third display mode, is outside the operation area AS. Move it to the placement position and display it. As a result, the infrequently used object OJ is excluded from the operation area AS, and the more frequently used object OJ can be constructed in the operation area AS.

Next, the object movement display process in the mobile terminal device 10 of the second embodiment will be described with reference to the flowchart shown in FIG. FIG. 12 is a flowchart showing an example of the object movement display process of the second embodiment. Since S11 to S16 are the same as in the case of the first embodiment shown in FIG. 4, S21 and subsequent sections will be described.

The determination unit 28 determines whether or not the arrangement position of the object is included in the operation area AS (S21: determination step). When the object is located in the operation area AS as shown in FIG. 13A, the determination unit 28 determines that the arrangement position is included (YES in S21), and the determination unit 28 is in the operation area AS. If the object is not located, it is determined that the placement position is not included (NO in S21).

When the blank area forming unit 31 is determined to have a specific inclination by the specific inclination determination unit 24 (YES in S16), and the determination unit 28 determines that the operation area AS includes at least one arrangement position. In (YES in S21), a blank area BA is formed in the operation area AS as shown in FIG. 13 (B) (S22: blank area forming step).

When the leader line display control unit 32 forms the blank area BA (S22) or the object is not located in the operation area AS (NO in S21), the leader line display control unit 32 has all the objects outside the operation area AS (FIG. 13). In (A), a plurality of leader lines (in FIG. 13C, two leader lines L1 and ten leader lines L2) from the 12 objects OJ of "A" to "N") toward the blank area BA. ) Is displayed (S23: Leader line display step).

The control unit 21 determines whether or not there is a pulling operation based on the detection signal from the touch panel 13 (S24). The display changing unit 25 touches the leader line of one of the plurality of leader lines (the leader line L1 of the object OJ of "A" in FIG. 13 (C)) with the operation finger U of the right hand, and the blank area BA. When the touch panel 13 detects the operation of moving toward (YES in S24), the object connected to the one leader line (in FIG. 13 (D), the object OJ of "A"). Is moved to the blank area BA and displayed (S25: display change step). On the other hand, when there is no manual pulling operation (NO in S24), the control unit 21 ends this process.

The control unit 21 ends this process when it is determined that there is no instruction in the operation area AS (NO in S13) or after S25.

As described above, according to the second embodiment, an appropriate operation area AS can be set as in the first embodiment described above. Further, when the mobile terminal device 10 is tilted toward the operation finger U side, a plurality of leader lines L1 and L2 heading from all the objects OJ outside the operation area AS to the blank area BA in the operation area AS are displayed, and the leader lines L1 are displayed. By touching with the operation finger U and pulling it by hand, the object OJ connected to the leader line L1 is moved to the blank area BA, so that the object OJ can be reliably moved to the position where the operation finger U can reach. .. This makes it possible to improve the operability of the mobile terminal device 10 with one hand. In addition, it is possible to provide a new and interesting movement operation called a hand-pulling operation.

Next, the mobile terminal device 10 according to the third embodiment will be described with reference to FIGS. 15 to 17. FIG. 15 is a block diagram showing the configuration of the mobile terminal device 10 according to the third embodiment. Of the configurations shown in FIG. 15, the same configurations as those shown in FIG. 2 of the above-mentioned first embodiment are designated by the same reference numerals and the description thereof will be omitted.

The control unit 20 shown in FIG. 15 includes a group setting unit 41, a display screen change unit 42, a display screen return unit 43, and a priority arrangement unit 44.

The group setting unit 41 arranges the plurality of objects in the order of the frequency of use by using the frequency of use for each of the plurality of objects stored in the frequency storage unit 152, and divides the plurality of objects into predetermined numbers from the top of the frequency of use. Set up multiple groups. For example, as a predetermined number (for example, 4) of objects belonging to the first group most frequently used, in FIG. 17B, "A", "B", "M", and "H" are shown. There are four objects OJ. As the predetermined number (for example, 4) of objects belonging to the second group that is used most frequently next, in FIG. 17C, "E", "F", "I", and "J" are shown. There are four objects OJ. The predetermined number (for example, 4) of objects belonging to the third group, which is the next most frequently used object, is "C", "D", "G", and "N" in FIG. 17 (D). There are four objects OJ.

As shown in FIG. 17A, when the display screen changing unit 42 is determined to have a specific inclination by the specific inclination determination unit 24, the display of the screen of the display unit 12 is displayed as shown in FIG. 17B. Is switched to the display of the first group screen as the group screen which is the next screen, and the predetermined group belongs to the most frequently used first group set by the group setting unit 41 in the operation area AS on the first group screen. A large number of objects (in FIG. 17B, four objects OJ of "A", "B", "M", and "H") are displayed. As a result, the objects outside the operation area AS can be grouped according to their frequency of use, and the first group screen in which the objects belonging to the first group with the highest frequency of use are moved to the operation area AS can be displayed as the next screen. It is possible to make the user aware that the group screen is different from the normal display screen.

When the display screen changing unit 42 determines that the first group screen shown in FIG. 17B is displayed and the specific tilt determination unit 24 determines that the first group screen has a specific inclination, the display screen changing unit 42 determines that the first group screen of the display unit 12 has a specific inclination. Is switched to the display of the second group screen, which is the next screen shown in FIG. 17C, and the frequency of use next to the first group set by the group setting unit 41 in the operation area AS on the second group screen. The predetermined number of objects belonging to the second group having a high value (in FIG. 17C, four objects OJ of "E", "F", "I", and "J") are displayed. As a result, the second group screen in which the object belonging to the second group most frequently used is moved to the operation area AS can be displayed as the next screen, and the object of the second group can also be selected with the operation finger U.

In the display screen return unit 43, the inclination of the housing 11 detected by the sensor 16 is tilted in the state where each group screen shown in FIGS. 17 (B) to 17 (D) is displayed by the display screen change unit 42. , When the specific tilt determination unit 24 determines that the return tilt is tilted toward the side opposite to the operation finger U of the right hand, the display of each group screen shown in FIGS. 17B to 17D. Then, as shown in FIG. 17A, the display is returned to the original screen in which the plurality of objects are displayed at the plurality of predetermined arrangement positions. As a result, the user can return to the original screen display by simply tilting the housing 11 back, that is, by performing a single return tilt operation. It should be noted that the display screen return unit 43 may return in the order of FIGS. 17 (D), 17 (C), 17 (B), and 17 (A) each time the return tilt is determined. good.

The display screen changing unit 42 may display the information display indicating the information regarding each group screen shown in FIGS. 17 (B) to 17 (D) on the screen of the display unit 12. For example, as the information display showing the information about the first group screen shown in FIG. 17B, there are "highest usage frequency group", "first group" and the like. As the information display showing the information about the second group screen shown in FIG. 17C, there are "top second frequency group", "second group" and the like. As a result, by looking at the information about the group screen, it is possible to grasp which group screen is displayed, and the user can be made aware that the group screen is displayed.

The priority arrangement unit 44 preferentially arranges frequently used objects at positions along the locus of touch positions in the operation area AS of the group screen. For example, in FIG. 17B, when the four objects OJ of "B", "A", "M", and "H" are used most frequently in that order (frequency of use is "B"> "A">. (When "M"> "H"), three objects OJ of "B", "A", and "M" are arranged along the limit line BL as shown in FIG. 17 (B), and the limit is reached. The object OJ of "H" is arranged at a position away from the line BL. As a result, since the vicinity of the limit line BL is a position where the operating finger U can be touched without bending the first joint or the second joint of the operating finger U, it is the position where the operating finger U is most easily operated. Therefore, by preferentially arranging the frequently used objects at this position, the operability can be further improved.

Next, the object movement display process in the mobile terminal device 10 of the third embodiment will be described with reference to the flowchart shown in FIG. FIG. 16 is a flowchart showing an example of the object movement display process of the third embodiment. Since S11 to S16 are the same as in the case of the first embodiment shown in FIG. 4, S31 and subsequent steps will be described.

After S12, the control unit 21 stores the usage frequency of each of the plurality of objects in the usage frequency storage unit 152 (S31: usage frequency storage step). For example, the control unit 21 stores the total number of touch operations (usage frequency) for each object in the usage frequency storage unit 152 for a period from the latest day to a predetermined number of past days.

The group setting unit 41 arranges the plurality of objects in the order of the frequency of use by using the frequency of use for each of the plurality of objects stored in the frequency storage unit 152, and divides the plurality of objects into predetermined numbers from the top of the frequency of use. A plurality of groups are set (S32: group setting step).

When the display screen changing unit 42 determines that the specific inclination is determined by the specific inclination determination unit 24 (YES in S16), the display of the screen of the display unit 12 is the next screen as shown in FIG. 17 (B). Switch to the display of the first group screen as a group screen, and in the operation area AS on the first group screen, the predetermined number of objects belonging to the first group set by the group setting unit 41 and having the highest frequency of use ( In FIG. 17B, four objects OJ of “A”, “B”, “M”, and “H”) are displayed (S33: display screen change step).

Further, when the specific inclination determination unit 24 determines that the specific inclination is achieved (YES in S34), the display of the first group screen of the display unit 12 is displayed as the second group screen which is the next screen shown in FIG. 17 (C). In the operation area AS on the second group screen, the predetermined number of objects belonging to the second group, which is the second most frequently used object after the first group set by the group setting unit 41 (FIG. 17 (FIG. 17). In C), four objects OJ) of "E", "F", "I", and "J" are displayed (S35). After S35, it returns to S34.

On the other hand, when the specific inclination determination unit 24 determines that the inclination is not specific (NO in S34), the specific inclination determination unit 24 displays each group screen shown in FIGS. 17B to 17D. In the state, it is determined whether or not the tilt of the housing 11 detected by the sensor 16 is a return tilt tilted toward the side opposite to the operating finger U of the right hand (S36). When the specific tilt determination unit 24 determines that the display screen return unit 43 has a return inclination (YES in S36), the display screen return unit 43 is displayed in each group screen shown in FIGS. 17B to 17D. As shown in (A), the display is returned to the original screen in which the plurality of objects are displayed at the plurality of predetermined arrangement positions (S37).

The control unit 21 ends this process when it is determined that there is no instruction in the operation area AS (NO in S13) or after S37.

As described above, according to the third embodiment, the operability of the mobile terminal device 10 with one hand can be improved as in the first embodiment described above. Further, the first group screen in which the objects outside the operation area AS are grouped according to the frequency of use and the objects belonging to the first group with the highest frequency of use are moved to the operation area AS can be displayed as the next screen. It is possible to make the user aware that the group screen is different from the display screen of.
