Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 is a diagram illustrating a hardware configuration example of a computer system to which the exemplary embodiment is applied.
As shown in the figure, this computer system includes a PC (Personal Computer) 10, a display 20, a keyboard 30, a tablet 40, and an electronic pen 50.

  The PC 10 is a device that processes information input from the keyboard 30 or the tablet 40 and outputs the processed information to the display 20. Although not shown, the PC 10 includes a CPU (Central Processing Unit) that is a calculation means, a main memory that is a storage means, and a magnetic disk device (HDD: Hard Disk Drive). Here, the CPU executes various software such as an OS (Operating System) and an application to realize each function. The main memory is a storage area for storing various software and data used for execution thereof, and the magnetic disk device is a storage area for storing input data for various software, output data from various software, and the like.

The display 20 is an example of a screen and is a device that displays information from the PC 10. For example, it is realized by a CRT (Cathode Ray Tube) display or a liquid crystal display.
The keyboard 30 is a device for inputting information to the PC 10 by pressing a key.
The tablet 40 is an example of a plate-like body, and is a device that electrically reads a position designated by the electronic pen 50 and inputs the position to the PC 10.
The electronic pen 50 is an example of a position pointing tool or a position pointing device, and is a device used to input information by pointing the tablet 40 with a pen tip that is an example of a pointing member.

  By the way, generally, the surface of the tablet 40 with which the electronic pen 50 comes into contact is flat. Therefore, when a character input, image input, or instruction input to the operation target displayed on the display 20 is performed using a combination of the tablet 40 and the electronic pen 50, the user feels that he / she writes on normal paper. It is less likely to get a sense of discomfort than when using a normal writing instrument. In order to obtain a natural writing sensation as much as possible, there is a method of roughening the surface of the tablet 40, but even this method has not yet achieved a satisfactory writing sensation. In particular, when an operation target is displayed on the tablet 40, the method of roughening the surface cannot be adopted because it impairs the visibility of the operation target.

  Further, when an input operation is performed with the electronic pen 50, the electronic pen 50 is positioned as intended by the user with respect to an operation target, for example, a character input area, an image input area, a check button, an image page tab, or the like. Is not easy. Therefore, the user has to operate while checking whether the electronic pen 50 is positioned on the operation target while viewing the operation target on the display 20 and the pointer indicating the pen tip. This made the input by the user's tablet 40 and electronic pen 50 inconvenient.

  Therefore, in the present embodiment, the pen tip of the electronic pen 50 can be moved relative to the main body so that the dynamic sense is transmitted to the user. At that time, for example, the pen tip of the electronic pen 50 is vibrated with a random waveform according to the speed and position thereof, and the user feels a rough and rough feeling of the background as when writing on paper or the like. To. Further, the controller that controls the movement of the movable part of the pen tip of the electronic pen 50 includes the position of the symbol (cursor) indicating the pen tip on the display 20 determined by the pen tip position and the operation displayed on the display 20. When the target position approaches or overlaps, the pen tip is moved.

Next, a functional configuration of the electronic pen 50 that performs such an operation will be described.
FIG. 2 is a block diagram illustrating a functional configuration example of the electronic pen 50.
The pen tip position detection unit 51 detects the position of the pen tip (cursor displayed) of the electronic pen 50 obtained from the tablet 40, and outputs pen tip position information indicating the position of the pen tip. In the present embodiment, the pen position information is used as an example of the first position information indicating the position on the plate-shaped body instructed by the indicating member, and the first position from which the first position information is acquired. As an example of the information acquisition unit, a pen tip position detection unit 51 is provided.
The operation target detection unit 52 detects the position of the operation target (object) displayed on the display 20 based on information from the PC 10 and outputs operation target position information indicating the position of the operation target. In the present embodiment, the operation target position information is used as an example of the second position information indicating the position of the operation target on the screen, and an example of a second position information acquisition unit that acquires the second position information. As shown, an operation target detection unit 52 is provided.

The positional relationship comparison unit 53 compares the pen tip position information output from the pen tip position detection unit 51 with the operation target position information output from the operation target detection unit 52, and the relationship between the pen tip position and the operation target position. Output predetermined activation information.
The activation signal generator 54 generates an activation signal for activating the pen tip movable mechanism 55 based on the activation information output by the positional relationship comparison unit 53 and the position information output by the pen tip position detection unit 51. In the present embodiment, an activation signal generator 54 is provided as an example of a control unit that controls the relative movement of the position pointing tool.
The pen tip moving mechanism 55 is a mechanism for operating the pen tip of the electronic pen 50 based on the start signal generated by the start signal generator 54. Details of the pen tip moving mechanism 55 will be described later.

Next, the activation signal generator 54 will be described.
FIG. 3 is a diagram relating to a first configuration example of the activation signal generator 54.
As shown in (a), the activation signal generator 54 in this case includes a pulse generation controller 61, a first pulse generator 62, and a second pulse generator 63.
The pulse generation controller 61 activates the first pulse generator 62 or the second pulse generator 63 according to the activation information output from the positional relationship comparison unit 53.
The first pulse generator 62 generates a pulse A having a predetermined shape as an activation signal for operating the pen tip moving mechanism 55.
The second pulse generator 63 generates a pulse B having a predetermined shape different from the pulse A as an activation signal for operating the pen tip movable mechanism 55.

Here, the pulse A and the pulse B will be described.
(B) is a diagram showing a specific example of pulse A and pulse B. FIG.
As shown in the figure, the pulse A has a convex shape, and causes the pen tip movable mechanism 55 to perform an operation of projecting the pen tip as an example of a relative motion of the pen tip in the direction of the tablet 40. This is a pulse. Further, the pulse B has a concave shape, and as an example of a relative operation in the direction opposite to the direction of the tablet 40 of the pen tip, the pen tip movable mechanism 55 is caused to perform the operation of retracting the pen tip. It is a pulse.

FIG. 4 is a diagram relating to a second configuration example of the activation signal generator 54.
As shown in (a), the activation signal generator 54 in this case includes a pen speed detector 66, vibration pattern ROMs 67-1 to 67-n, a vibration generation controller 68, a D / A converter 69, and the like. Is provided.
The pen speed detector 66 detects the pen speed based on the pen tip position information output from the pen tip position detection unit 51 and information on the time taken to move the pen tip, and determines the pitch (cycle) of the vibration pattern. Output pitch information. In the present embodiment, a pen speed detector 66 is provided as an example of speed information acquisition means for acquiring speed information indicating the moving speed of the pointing member.
Each of the vibration pattern ROMs 67-1 to 67-n stores vibration pattern data that is a pattern for vibrating the pen tip.
The vibration generation controller 68 takes out vibration pattern data from any one of the vibration pattern ROMs 67-1 to 67-n according to the activation information output from the positional relationship comparison unit 53, and the pitch information output from the pen speed detector 66. The generation of the vibration pattern is controlled by transforming and outputting the vibration pattern data corresponding to the pen speed based on the above.
The D / A converter 69 converts the vibration pattern data output from the vibration generation controller 68 into an activation signal that is an analog signal.
In this configuration example, the pen speed detector 66 that has received the pen tip position information output from the pen tip position detector 51 determines the pen speed. For example, an acceleration sensor is provided in the electronic pen 50, and the acceleration is detected. The sensor may determine the pen speed.

Here, the vibration pattern serving as the activation signal will be described.
(B) is a diagram showing specific examples of vibration pattern A, vibration pattern B, and vibration pattern C. FIG.
As shown in the figure, the vibration pattern A is a sine wave, the vibration pattern B is a triangular wave, and the vibration pattern C is a random wave. By switching between these vibration patterns, the writing quality of the electronic pen 50 changes. That is, these vibration patterns are used to generate an activation signal that makes the user feel the texture of paper in a pseudo manner. For example, when a vibration pattern is associated with the texture of paper and a texture desired by the user is input, the vibration pattern associated with the texture may be selected. However, the present invention is not limited to the texture of paper, and some condition may be designated and a vibration pattern predetermined for the designated condition may be selected.
When the electronic pen 50 is run on the tablet 40, the pen speed detector 66 or the acceleration sensor detects the speed at which the pen tip runs on the tablet 40, and the pitch of the vibration pattern changes according to the speed. Specifically, when the pen tip travels at a low speed, the pitch increases (the cycle increases), and when the pen tip travels at a high speed, the pitch decreases (the cycle shortens). As a result, the user receives a feeling of writing on, for example, rough paper or corrugated board, even though the electronic pen 50 is running on the tablet 40.
Here, although three types of waveforms of sine wave, triangular wave, and random wave are shown as the vibration pattern, this is only an example, and other waveforms may be adopted.

Next, the pen tip movable mechanism 55 in the present embodiment will be described.
FIG. 5 is a diagram illustrating a first configuration example of the pen tip movable mechanism 55.
The first configuration example is an example of a pen tip moving mechanism 55 using a piezoelectric actuator.
As shown in the figure, the pen tip moving mechanism 55 in this case includes a power supply unit 71, a piezoelectric actuator 72, and an elastic material 73 as a mechanism for operating a pen shaft 70 extending from the pen tip.
The power supply unit 71 applies a voltage to the piezoelectric actuator 72 according to the activation signal output from the activation signal generator 54.
The piezoelectric actuator 72 expands and contracts in the direction of the pen shaft 70 in proportion to the voltage applied by the power supply unit 71.
The elastic material 73 is, for example, a spring that biases the pen shaft 70 in a direction in which the pen shaft 70 is in close contact with the piezoelectric actuator 72.
With such a configuration, since the piezoelectric actuator 72 pushes and pulls one end of the pen shaft 70, the pen tip moves in a direction protruding from the main body or in a direction retracting into the main body. The movable stroke of the pen tip at this time is preferably about 20 μm to 100 μm.

FIG. 6 is a diagram illustrating a second configuration example of the pen tip movable mechanism 55.
This second configuration example is an example of the pen tip moving mechanism 55 using a voice coil motor.
As illustrated, the pen tip movable mechanism 55 in this case includes a voice coil mechanism 74 and a bearing 75 as a mechanism for operating a pen shaft 70 extending from the pen tip. The voice coil mechanism 74 is supported by a bearing 75 so as to be rotatable about the pen shaft 70.
The voice coil mechanism 74 includes a bearing 741, a voice coil motor 742, and a coil position sensor 743. When the pen tip comes into contact with the tablet 40, the pen shaft 70 is rotated slightly around the bearing 741 in a direction parallel to the tablet 40, and the state is held by the voice coil motor 742. The coil position sensor 743 is attached to precisely control the amount of movement of the pen tip, and may be an optical sensor or a resistance sensor. The amount of movement of the pen tip at this time is preferably about 20 μm to 100 μm.
Even if the bearing 75 is not provided, if the pen tip is slightly angled, the user often uses the electronic pen 50 at a rotation angle at which the tablet 40 and the pen shaft 70 are parallel. Therefore, the bearing 75 is not always necessary.

FIG. 7 is a diagram illustrating a third configuration example of the pen tip movable mechanism 55.
This third configuration example is an example of the pen tip movable mechanism 55 using a rotary motor.
As illustrated, the pen tip movable mechanism 55 in this case includes a bearing 76, a rotary encoder 77, and a rotary motor 78 as a mechanism for operating a pen shaft 70 extending from the pen tip. In this configuration example, the pen tip is slightly bent (for example, about 50 μm) from the central axis of the pen shaft 70, and the pen shaft 70 is rotatably held by a bearing 76. The rotary encoder 77 outputs a pulse each time the pen shaft 70 rotates, for example, but may not be provided. In this configuration example, the pen tip is operated by rotating the pen shaft 70 by the rotation motor 78. If the rotary motor 78 is continuously rotated, the same effect as that of applying a sine wave vibration to the pen tip can be obtained. For example, it feels like the pen nib has risen. As described above, the third configuration example is a configuration example in which the pen tip can be vibrated with a simple mechanism as long as the vibration pattern is not changed.

  The pen tip movable mechanism 55 shown in FIGS. 5 to 7 is merely an example. Any mechanism may be adopted as long as it can transmit the pulse-like operation shown in FIG. 3 and the vibration of the vibration pattern shown in FIG. 4 to the pen tip.

In the present embodiment, as described above, control for operating the pen tip is performed in accordance with the relationship between the position of the pen tip and the position of the operation target.
Therefore, an example of an operation screen including an operation target by the electronic pen 50 is shown.
FIG. 8A is a diagram illustrating a first operation screen example.
This first operation screen example is a registration screen for a user to register a handwritten signature.
As shown in the figure, a sign input field 81 for inputting a handwritten signature is displayed on the display 20.
Conventionally, when a handwritten signature is input in the signature input field 81, the handwritten signature sometimes protrudes from the signature input field 81. If this happens, an image of a valid handwritten signature will not be registered in the system.

Therefore, in the present embodiment, when the pen tip cursor overlaps the frame portion of the sign input field 81, the pen tip is moved in a pulse shape. For example, when the pen tip is about to protrude from the frame of the sign input field 81, the user feels that the pen tip is raised by moving the pen tip according to the pulse A. Further, if the state where the pen tip is likely to protrude from the frame of the sign input field 81 is avoided, the pen tip is moved like a pulse B to give the user a depressed feeling. By doing so, the user can input the handwritten signature correctly so as to fit in the signature input field 81.
Also, areas are set on the inside and outside of the frame of the sign input field 81, and the vibration pattern, amplitude, and pitch of the pen tip are different depending on whether the area is located on the inside area or the outside area. Any or all of them may perform different operations.

In the figure, the area centering on the frame of the sign input field 81 (frame area) is shown by shading, but this shading is given for explanation and is displayed on the actual operation screen. You don't have to. Here, the frame region is an example of a predetermined region along the boundary of the operation target.
In the figure, the leftmost X coordinate, rightmost X coordinate, uppermost Y coordinate, and lowermost Y coordinate of the frame of the sign input field 81 are X01, X02, Y01, and Y02, respectively. The X coordinate of the left end of the inner circumference, the X coordinate of the right end, the Y coordinate of the upper end, and the Y coordinate of the lower end are X03, X04, Y03, and Y04, respectively. It is also shown that the coordinates, the upper Y coordinate, and the lower Y coordinate are X05, X06, Y05, and Y06, respectively.

FIG. 8A is a diagram illustrating a second operation screen example.
The second operation screen example is an input screen for a user to input a figure or the like freehand.
Even in this second operation screen example, the movement of the electronic pen 50 can be guided so that the figure or the like fits in the freehand input field 82. However, in this second operation screen example, in addition, the center Marker information such as lines 83 and 84 can be known not only from the visual sense but also from the movement of the pen tip. Thereby, the user can input a figure etc. correctly.

  Further, on the side opposite to the pen tip of the electronic pen 50, a movable mechanism similar to the pen tip movable mechanism 55 and an eraser member having a size of an eraser instead of the pen tip are provided, and the acceleration within the electronic pen 50 is provided. When a sensor such as a sensor, a mercury switch, or a ball switch is incorporated and the electronic pen 50 is inverted, the eraser member is caused to operate like an eraser attached to a pencil. Also good. In this case, when erasing a freehand drawing or the like that has already been written, when the part to be erased is touched, an operation for giving a vibration or a feeling of excitement is given to the eraser member, and the user is scraped off. You may make it give such a feeling.

In the drawing, the frame of the freehand input field 82 and the area centered on the center lines 83 and 84 (frame area) are shaded, but this shading is given for explanation. It does not have to be displayed on the actual operation screen. Here, the frame region is an example of a predetermined region along the boundary of the operation target.
In the figure, the left end X coordinate, the right end X coordinate, the upper end Y coordinate, and the lower end Y coordinate of the freehand input field 82 are X11, X12, Y11, and Y12, respectively. The X coordinate of the left end of the inner periphery, the X coordinate of the right end, the Y coordinate of the upper end, and the Y coordinate of the lower end are X13, X14, Y13, and Y14, respectively, and the X coordinate of the left end of the outer periphery of the frame region and the right end It is also shown that the X coordinate, the upper Y coordinate, and the lower Y coordinate are X15, X16, Y15, and Y16, respectively. Further, the X coordinate of the center line 83, the X coordinate of the left end of the frame region, and the X coordinate of the right end of the frame region are X17, X18, and X19, respectively, and the Y coordinate of the center line 84 and the upper end of the frame region It is also shown that the Y coordinate of Y and the Y coordinate of the lower end of the frame area are Y17, Y18, and Y19, respectively.

FIG. 8C is a diagram illustrating a third operation screen example.
The third operation screen example is a selection screen for selecting any of the check boxes 85-1 to 85-5 to select a paper size. Hereinafter, the check boxes 85-1 to 85-5 are collectively referred to as the check box 85.
In this third example of the operation screen, when the user tries to check the check box 85, if the check box 85 is valid, the pen tip is vibrated or operated in a pulsed manner to check the check box 85. Inform the user that he is going to select 85.
For example, consider a case where the paper sizes B4 and A3 cannot be selected. In this case, since the check boxes 85-2 and 85-3 corresponding to the paper sizes B4 and A3 are invalid, as shown in the drawing, the color (and color different from the valid check boxes 85-1, 85-4 and 85-5) For example, it is displayed in grayout. When the cursor is over the valid check boxes 85-1, 85-4, and 85-5 corresponding to A4, B5, and Letter paper sizes, the pen tip is vibrated or operated in a pulsed manner. On the other hand, even if the cursor is over the invalid check boxes 85-2 and 85-3, the pen tip is not operated.

  Further, for the check box 85 for important selection, for example, payment approval, the entire check box 85 may be requested to be filled. During the filling operation, the pen tip is continuously vibrated to indicate that it is being painted. When the filling of the check box 85 is visually finished or when a predetermined filling operation time has elapsed, the completion of the filling is presented to the user by stopping the vibration indicating that the filling is in progress. To do. In this way, by requesting a series of painting operations, the user can make an appropriate determination regarding the selection of the important check box 85. In addition, the user can easily understand the start and completion of painting with the electronic pen 50.

  In the figure, the X coordinate of the left end of the frame of the check boxes 85-1, 85-2, 85-3, the X coordinate of the right end of the frame, the left end of the frame of the check boxes 85-4, 85-5 are shown. The X coordinate and the X coordinate of the right end of those frames are X21, X22, X23, and X24, respectively, the Y coordinate of the upper ends of the check boxes 85-1, 85-4, and the Y coordinate of the lower ends of those frames , The Y coordinate of the upper ends of the frames of the check boxes 85-2 and 85-5, the Y coordinate of the lower ends of the frames, the Y coordinate of the upper ends of the frames of the check box 85-3, and the Y coordinate of the lower ends of the frames, respectively. , Y21, Y22, Y23, Y24, Y25, and Y26.

FIG. 8B is a diagram illustrating a fourth operation screen example.
The fourth operation screen example is an operation screen displayed by training software for writing beautiful characters.
In the fourth operation screen example, a character image 86 which is a model representing a correct character shape is displayed in advance. When the user traces the character image 86 with the electronic pen 50, the pen tip is operated when the user deviates from the character image 86. As a result, the user can acquire a beautiful character shape from the senses of the sight and the nib, and learning progresses as compared with the feedback from the conventional sight.

  In the figure, the area (frame area) centered on the frame of the character image is shown by shading, but this shading is given for explanation and is not displayed on the actual operation screen. It's okay. Here, the frame region is an example of a predetermined region along the boundary of the operation target.

Next, the operation of the positional relationship comparison unit 53 in the present embodiment will be described.
FIG. 9 is a flowchart showing an operation example of the positional relationship comparison unit 53. The positional relationship comparison unit 53 periodically performs the operation shown in this flowchart. In FIG. 3, the start signal generator 54 outputs a start signal that causes the pen tip to perform a pulse-like operation. In FIG. 4, the start signal generator 54 causes the pen tip to vibrate a vibration pattern. The configuration for outputting the start signal has been described as a separate and independent configuration, but in this operation example, the start signal generator 54 causes the pen tip to perform a pulse-like operation and the vibration of the vibration pattern on the pen tip. It is assumed that both the start signal for performing In addition, an operation example applicable to operations on all the operation screens in FIGS.

When the operation timing comes, the positional relationship comparison unit 53 first determines whether or not the pen tip of the electronic pen 50 is in contact with the tablet 40 (step 501). This determination is performed based on, for example, a signal from the pen tip position detection unit 51.
As a result, if it is determined that the pen tip of the electronic pen 50 is not in contact with the tablet 40, the process ends. If it determines with the pen tip of the electronic pen 50 contacting the tablet 40, the positional relationship comparison part 53 will acquire pen tip position information from the pen tip position detection part 51 (step 502), and operation target detection part Operation target position information is acquired from 52 (step 503). Here, the operation target position information includes, for each operation target displayed on the operation screen, an area occupied by the operation target (hereinafter referred to as “operation target area”) and a frame area of the operation target. It includes information that identifies an inner area (hereinafter referred to as “inner frame area”) and an area outside the operation target (hereinafter referred to as “outer frame area”) of the operation target frame area.

Thereafter, the positional relationship comparison unit 53 determines whether or not the pen tip position acquired in step 502 is within any of the operation target areas specified by the operation target position information acquired in step 503 ( Step 504).
As a result, if it is determined that the pen tip position is within the operation target area of any one of the operation targets, the positional relationship comparison unit 53 displays the vibration of the vibration pattern indicating that the pen tip is within the operation target area. The activation information to be performed first is output (step 505). However, depending on the operation definition, the activation information may not be output. Then, the positional relationship comparison unit 53 determines whether or not the pen tip position acquired in step 502 is within the inner frame region of any operation target specified by the operation target position information acquired in step 503 ( Step 506). If it is determined that the pen tip position is not within the inner frame region of any operation target, the process ends, but it is determined that the pen tip position is within the inner frame region of any operation target. For example, the positional relationship comparison unit 53 outputs activation information for causing the pen tip to perform a pulse-like operation indicating that the pen tip is in the inner frame region (step 507). However, depending on the operation definition, the activation information may not be output.

  On the other hand, if it is determined in step 504 that the pen tip position is not in any of the operation target operation target areas, the positional relationship comparison unit 53 determines that the pen tip position acquired in step 502 is the operation acquired in step 503. It is determined whether it is within the outer frame area of any operation target specified by the target position information (step 508). If it is determined that the pen tip position is not within the outer frame area of any operation target, the process ends, but it is determined that the pen tip position is within the outer frame area of any operation target. For example, the positional relationship comparison unit 53 outputs activation information for causing the pen tip to perform a pulse-like operation or a vibration pattern indicating that the pen tip is in the outer frame region (step 509). However, depending on the operation definition, the activation information may not be output.

"Near: Pulse A, Far: Pulse B" is specified as the operation in the outer frame region corresponding to "". Therefore, in step 509, if the pen tip approaches the center lines 83 and 84, the positional relationship comparing unit 53 outputs activation information for causing the pen tip to perform the operation of the pulse A, and the pen tip is the center line. If it is away from 83 and 84, activation information for causing the pen tip to perform the operation of pulse B is output.
