detailed description

The following will explain the virtual navigation device, navigation method and computer program product provided by the present invention through the embodiments. However, the embodiments of the present invention are not intended to limit the present invention to be implemented in any environment, application or manner as described in the embodiments. Therefore, the descriptions about the embodiments are only for the purpose of illustrating the present invention, rather than directly limiting the present invention. It should be noted that in the following embodiments and drawings, elements not directly related to the present invention have been omitted and not shown.

The first embodiment of the present invention is a virtual navigation device 1, the schematic diagram of which is depicted in FIG. 1A. The virtual navigation device 1 includes a processor 11 , a touch detection module 13 , a work surface 15 and a transceiver interface 17 . The touch detection module 13 is electrically connected to the processor 11 and the working surface 15 , and the processor 11 is electrically connected to the transceiver interface 17 .

The processor 11 may be any one of various processors, central processing units, microprocessors or other computing devices known to those skilled in the art to which the present invention pertains. The working surface 15 can be planar or non-planar (for example: an arc surface suitable for placing human fingers according to ergonomic design). The touch detection module 13 corresponds to the working surface 15 and can be a capacitive, resistive, optical, piezoelectric or other type of touch detection module. These different types of touch detection modules and their operation methods are well known to those with ordinary knowledge in the technical field of the present invention, so details are not repeated here. In addition, the transceiving interface 17 can be various transceiving interfaces well known to those skilled in the art of the present invention.

In this embodiment, the touch detection module 13 detects a plurality of detection information 12a, 12b, 12c, 12d within a time interval T1, as shown in FIG. 1B. Those with ordinary knowledge in the technical field of the present invention can easily understand that different types of touch detection modules 13 will detect different types of detection information 12a, 12b, 12c, 12d. The processor 11 then determines that at least three touch objects are in contact with the working surface 15 within the time interval T1 according to the detection information 12a, 12b, 12c, and 12d. Afterwards, the processor 11 determines a piece of movement information of each touch object according to the detection information 12 a , 12 b , 12 c , and 12 d , and then determines a position information signal 10 according to the movement information. If the transceiver interface 17 is connected to a host (not shown), the transceiver interface 17 will transmit the position information signal 10 to the host, so that the host moves a cursor on a screen according to the position information signal 10 .

In other implementations, if the virtual navigation device 1 further includes a screen, or the touch detection module 13 is a touch screen, the position information signal 10 determined by the aforementioned processor 11 can also be used to move the virtual navigation device 1 on-screen cursor. In this type of implementation, since the virtual navigation device 1 is not connected to an external host, the sending and receiving interface 17 may not be configured.

Next, how to specifically determine the position information signal 10 in this embodiment will be described by taking the situation that the above-mentioned at least three touch objects include a first touch object, a second touch object, and a third touch object.

The processor 11 determines according to the detection information 12a, 12b, 12c, 12d that within the time interval T1, the first touch object moves from the position P1 on the work surface 15 to the position P2, and the second touch object moves from the position P2 on the work surface 15. The position P3 moves to the position P4 and the third touch object moves from the position P5 to the position P6 on the working surface 15 , as shown in FIG. 1C . The processor 11 calculates a first distance between the position P1 and the position P2, calculates a second distance between the position P3 and the position P4, and calculates a third distance between the position P5 and the position P6. Afterwards, the processor 11 calculates an average value of the first distance, the second distance and the third distance, and uses the average value as the position information signal 10 . In short, the processor 11 uses the average value of the moving track lengths of the first touch object, the second touch object and the third touch object as the position information signal 10 .

In other implementations, the processor 11 may instead determine, based on the detection information 12a, 12b, 12c, and 12d, that the first touch object moves from the position P1 on the work surface 15 to the position P2, the second The second touch object moves from the position P3 on the working surface 15 to the position P4 and the third touch object moves from the position P5 to the position P6 on the working surface 15 , as shown in FIG. 1C . Processor 11 calculates a first average value of positions P1, P3, P5, calculates a second average value of positions P2, P4, P6, calculates a difference between the second average value and the first average value, and then The difference is used as position information signal 10. In short, the processor 11 uses the track lengths of the center of gravity of the first touch object, the second touch object and the third touch object as the position information signal 10 .

In other implementations, the processor 11 may determine the location information signal 10 in other ways. Specifically, the processor 11 first defines a polygon according to a plurality of positions where the first touch object, the second touch object, and the third touch object contact the working surface 15 . The processor 11 then determines a moving direction and a moving distance contained in the position information signal 10 according to the change of an area of the polygon within the time interval T1 (for example: becoming larger, smaller, deforming in different directions, etc.). Taking the three different situations shown in FIG. 1D, FIG. 1E, and FIG. 1F as examples, the processor 11 first defines the polygon 102a according to the positions P1, P3, and P5, and then determines that the polygon 102a changes into the polygon 102b and the second polygon within the time interval T1. The area between them changes, and the moving direction and moving distance included in the position information signal 10 are determined accordingly. Specifically, the moving directions in FIG. 1D , FIG. 1E , and FIG. 1F are “upper right”, “clockwise” and “outward”.

In the implementation described in the preceding paragraph, the moving direction carried by the position information signal 10 can enable the host to control a visual change effect or an auditory change effect. The visual change effect may include one or a combination of rotation, zoom-in, and zoom-out of a display area on the screen, wherein the display area displays one or a combination of a graph, a window, and a cursor. As for the auditory changing effect, it may include one or a combination of a volume control, a sound effect selection and a sound effect mixing. Taking FIG. 1E as an example, the moving direction determined by the processor 11 is "clockwise direction", and the host can increase its volume according to the moving direction, and determine the magnitude of the volume increase according to the moving distance. Taking FIG. 1F again as an example, the moving direction determined by the processor 11 is "outward", and the host computer can enlarge the picture presented on the screen according to the moving direction, and determine the zooming range according to the moving distance.

In other implementations, the processor 11 may determine the location information signal 10 in other ways. Specifically, the processor 11 determines a moving direction included in the position information signal 10 according to a moving track of each touch object on the working surface 15 within the time interval T1. The processor 11 further calculates an average value of the moving trajectories as a moving distance included in the position information signal 10 . Taking the two different situations shown in FIG. 1G and FIG. 1H as examples, the processor 11 moves the trajectory of the first touch object, the second control object, and the third touch object on the work surface 15 within the time interval T1 104a, 104b, 104c, determine a moving direction included in the location information signal 10 . Specifically, the moving directions in FIG. 1G and FIG. 1H are “clockwise” and “outward” respectively. Next, the processor 11 calculates the average value of the moving trajectories 104 a , 104 b , and 104 c as the moving distance included in the location information signal 10 . Similarly, in this embodiment, the moving direction carried by the position information signal 10 enables the host to control a visual change effect or an auditory change effect.

The above-mentioned various ways of determining the position information signal 10 are described in the case of three touch objects. How the processor 11 determines the position information signal 10 when the object contacts the working surface 15 within the time interval T1 is omitted here.

Furthermore, the virtual navigation device 1 can further judge that the touch object on the work surface 15 is a human finger before continuing to perform subsequent operations (that is, determine the position information signal 10, and control the touch screen on the screen according to the position information signal 10). cursor or on-screen visual and/and audible change effects). Similarly, the above-mentioned at least three touch objects include a first touch object, a second touch object and a third touch object to illustrate how to detect whether the touch objects are human fingers. The processor 11 determines according to the detection information 12a, 12b, 12c, 12d that within the time interval T1, the first touch object moves from the position P1 on the work surface 15 to the position P2, and the second touch object moves from the position P2 on the work surface 15. The position P3 moves to the position P4 and the third touch object moves from the position P5 to the position P6 on the working surface 15 , as shown in FIG. 1C . Next, the processor 11 determines whether the first touch object, the second touch object, and the third touch object are human beings according to the relative positions between the positions P1, P3, and P5 and the relative positions between the positions P2, P4, and P6. finger. If it is a human finger, the processor 11 will further determine the position information signal 10 , and control the cursor on the screen or the visual and/or auditory change effect on the screen according to the position information signal 10 .

Through the configuration of the first embodiment, the user does not need to hold a device with a hardware shape by hand, but only needs to place the touch object (such as a finger) on the working surface 15 of the virtual navigation device 1, and then Moving the touch object on the working surface 15 can control the cursor on the screen or the visual and/or auditory changing effects on the screen. In addition, the virtual navigation device 1 can be designed such that when the touch object on the work surface 15 is a human finger, subsequent operations will be performed based on the position information signal 10, thereby avoiding non-humans (such as: pets) from accidentally touching The impact of working face 15.

Please refer to FIG. 2A and FIG. 2B for the second embodiment of the present invention. The virtual navigation device 1 in the second embodiment can also perform all the operations and functions that it can perform in the first embodiment. However, in the second embodiment, the virtual navigation device 1 continues to operate in the time interval T2 after the time interval T1. Only the differences between the second embodiment and the first embodiment will be described in detail below.

Similar to the first embodiment, the touch detection module 13 detects a plurality of detection information 12a, 12b, 12c, 12d within the time interval T1, as shown in FIG. 2B. The processor 11 then determines that there are at least three touch objects (for example: the first touch object, the second touch object, and the third touch object) within the time interval T1 according to the detection information 12a, 12b, 12c, and 12d. The working faces 15 are in contact. Afterwards, the processor 11 judges the movement information of each touch object according to the detection information 12a, 12b, 12c, 12d, and then determines the position information signal 10 according to the movement information. At this point, the navigation function of the virtual navigation device 1 is already in operation.

After the navigation function of the virtual navigation device 1 operates, the touch detection module 13 detects a plurality of detection information 24 a , 24 b , 24 c , 24 d within a time interval T2 after the time interval T1 . At this time, according to the content of the detection information 24a, 24b, 24c, 24d, there will be several different situations, which are illustrated as follows.

Let me explain the first case first. The processor 11 judges that the first touch object, the second touch object, the third touch object and the fourth touch object are located on the working surface 15 within the time interval T2 according to the detection information 24a, 24b, 24c, 24d. After the processor 11 determines that the fourth touch object is located on the working surface 15 within the time interval T2, it determines an operation signal 20a. The transceiver interface 17 then transmits the operation signal 20a to the host, so that the host performs an operation according to the operation signal 20a. In short, in the first case, the navigation function of the virtual navigation device 1 has already been operated in the time interval T1. Therefore, in the subsequent time interval T2, if another touch object (for example: the aforementioned fourth touch object), the virtual navigation device 1 will generate an operation signal 20a, so that the host can perform appropriate operations accordingly.

Next, the second case will be described. The processor 11 judges that the first touch object, the second touch object, the third touch object and the fourth touch object are located on the working surface 15 within the time interval T2 according to the detection information 24a, 24b, 24c, 24d. After the processor 11 determines that the fourth touch object is located on the work surface 15 within the time interval T2, it determines an operation signal 20a. In addition, the processor 11 determines an operation signal 20b after determining that the first touch object, the second touch object and the third touch object are located on the working surface 15 within the time interval T2. Afterwards, the transceiver interface 17 transmits the operation signals 20a, 20b to the host, so that the host performs a first operation and a second operation respectively according to the operation signals 20a, 20b.

In short, in the second case, the navigation function of the virtual navigation device 1 has already been operated in the time interval T1. Therefore, in the subsequent time interval T2, if another touch object (for example: the aforementioned fourth touch object), then the virtual navigation device 1 will operate differently for the movement modes of the original touch object and the newly added touch object. For example, in the time interval T1, the user first moves the three fingers of the right hand on the working surface 15, and in the subsequent time interval T2, the three fingers of the user's right hand are still moving on the working surface 15, but the left hand is added. one finger. According to the movement of the user's fingers in the time interval T2, the user can make the host perform different operations at the same time, for example: the user can increase the volume of the host by moving the right hand, and change the image volume on the screen by moving the left hand. Location.

Next, the third case will be described. The processor 11 determines that a fourth touch object is located on the working surface 15 within the time interval T2 according to the detection information 24a, 24b, 24c, 24d. The processor 11 further determines an operation signal 20 a after determining that the fourth touch object is located on the working surface 15 . Afterwards, the transceiver interface 17 transmits the operation signal 20a to the host, so that the host performs an operation according to the operation signal 20a. In short, in the third situation, the navigation function of the virtual navigation device 1 has already been operated in the time interval T1. Therefore, in the subsequent time interval T2, if another touch object (for example: the aforementioned fourth touch object), and the original three touch objects (for example: the first touch object, the second touch object and the third touch object) have left the work surface 15, the virtual navigation device 1 will still generate the operation signal 20a , allowing the host to take appropriate action accordingly.

Through the configuration of the second embodiment, after the navigation function of the virtual navigation device 1 has been operated, the user only needs to add at least one other touch object (for example: the aforementioned fourth touch object) to move on the work surface 15 , you can perform more different operations. In addition, even when the original touch object (for example: the aforementioned first, second and third touch objects) leaves the work surface 15, the virtual navigation device 1 can still move on the work surface 15 according to the movement method of other touch objects , to generate an operation signal 20a, so that the host can perform appropriate operations accordingly.

Please still refer to FIG. 2A and FIG. 2B for the third embodiment of the present invention. The operation of the virtual navigation device 1 in the third embodiment is similar to that in the second embodiment, so only the differences between the two will be described in detail below.

In the second embodiment, after the navigation function of the virtual navigation device 1 has been operated, the user only needs to add at least one other touch object to move on the work surface 15 , so as to perform more different operations. However, in the third embodiment, after the navigation function of the virtual navigation device 1 is operated, if the user wants to perform other additional operations, at least three other touch objects need to be added to move on the working surface 15 . In other words, in the third embodiment, each new operation requires at least three touch objects to move on the work surface 15 before it can be executed.

Specifically, after the navigation function of the virtual navigation device 1 operates, the touch detection module 13 detects a plurality of detection information 24a, 24b, 24c, 24d within the time interval T2 following the time interval T1. At this time, according to the content of the detection information 24a, 24b, 24c, 24d, there will be several different situations, which are illustrated as follows.

Let me explain the first case first. The processor 11 judges the first touch object, the second touch object, the third touch object, the fourth touch object, the fifth touch object and the sixth touch object according to the detection information 24a, 24b, 24c, 24d It is located on the working surface 15 during the time interval T2. After the processor 11 determines that the fourth touch object, the fifth touch object and the sixth touch object are located on the working surface 15 within the time interval T2, it determines an operation signal 20a. The transceiver interface 17 then transmits the operation signal 20a to the host, so that the host performs an operation according to the operation signal 20a.

Next, the second case will be described. The processor 11 judges the first touch object, the second touch object, the third touch object, the fourth touch object, the fifth touch object and the sixth touch object according to the detection information 24a, 24b, 24c, 24d It is located on the working surface 15 during the time interval T2. After the processor 11 determines that the fourth touch object, the fifth touch object and the sixth touch object are located on the working surface 15 within the time interval T2, it determines an operation signal 20a. In addition, the processor 11 determines an operation signal 20b after determining that the first touch object, the second touch object and the third touch object are located on the working surface 15 within the time interval T2. Afterwards, the transceiver interface 17 transmits the operation signals 20a, 20b to the host, so that the host performs a first operation and a second operation respectively according to the operation signals 20a, 20b.

Next, the third case will be described. The processor 11 determines that the fourth touch object, the fifth touch object and the sixth touch object are located on the working surface 15 within the time interval T2 according to the detection information 24a, 24b, 24c, 24d. The processor 11 further determines an operation signal 20 a after determining that the fourth touch object, the fifth touch object and the sixth touch object are located on the working surface 15 . Afterwards, the transceiver interface 17 transmits the operation signal 20a to the host, so that the host performs an operation according to the operation signal 20a.

In addition to the aforementioned operations, the third embodiment can also perform all the operations and functions of the first and second embodiments. Those skilled in the art can directly understand how the third embodiment performs these operations and functions based on the above-mentioned first and second embodiments, so details are omitted.

Through the configuration of the third embodiment, after the navigation function of the virtual navigation device 1 has been operated, if the user wants to perform other operations, it is necessary to add at least three other touch objects (for example: the aforementioned fourth and fifth touch objects). and the sixth touch object) move on the working surface 15 . In addition, even when the original touch object (for example: the aforementioned first, second and third touch objects) leaves the work surface 15, the virtual navigation device 1 can still move on the work surface 15 according to the movement method of other touch objects , to generate an operation signal 20a, so that the host can perform appropriate operations accordingly.

The fourth embodiment of the present invention is a virtual navigation device 3, the schematic diagram of which is depicted in FIG. 3A. The virtual navigation device 3 includes a processor 11 , a touch detection module 33 , a work surface 35 and a transceiver interface 17 . The touch detection module 33 is electrically connected to the processor 11 and the working surface 35 , and the processor 11 is electrically connected to the transceiver interface 17 . In this embodiment, the touch detection module 33 includes sub-touch detection modules 33a, 33b, the working surface 35 includes sub-working surfaces 35a, 35b, and the sub-working surfaces 35a, 35b do not overlap. In addition, the sub-touch detection module 33a corresponds to the sub-working surface 35a, and the sub-touch detection module 33b corresponds to the sub-working surface 35b. As for the processor 11 and the transceiver interface 17, the operations in the fourth embodiment are the same as those in the first to third embodiments, so details are omitted here.

FIG. 3B depicts the detection signal detected by the sub-touch detection module 33a, and FIG. 3C depicts the detection signal detected by the sub-touch detection module 33b. Specifically, the sub-touch detection module 33a detects a plurality of detection information 32a, 32b, 32c, 32d within the time interval T1, as shown in FIG. 3B. The processor 11 then determines that there are at least three touch objects (for example: the first touch object, the second touch object, and the third touch object) within the time interval T1 according to the detection information 32a, 32b, 32c, and 32d. The sub-working surfaces 35a are in contact. Afterwards, the processor 11 determines the movement information of each touch object according to the detection information 32a, 32b, 32c, 32d, and then determines the position information signal 30a according to the movement information. At this point, the navigation function of the virtual navigation device 3 is already in operation.

Similar to the second embodiment, the navigation function of the virtual navigation device 3 continues to operate in the time interval T2 after the time interval T1.

In the time interval T2, the sub-touch detection module 33b detects a plurality of detection information 34a, 34b, 34c, 34d, as shown in FIG. 3C. The processor 11 determines that a fourth touch object is located on the sub-working surface 35b within the time interval T2 according to the detection information 34a, 34b, 34c, 34d. After the processor 11 determines that the fourth touch object is located on the sub-working surface 35b, it determines an operation signal 30b. The transceiver interface 17 then transmits the operation signal 30b to the host, so that the host performs a first operation according to the operation signal 30b.

On the other hand, if the sub-touch detection module 33a detects a plurality of detection information 36a, 36b, 36c, 36d within the time interval T2. The processor 11 judges that the first touch object, the second touch object and the third touch object are located on the sub-working surface 35a within the time interval T2 according to the detection information 36a, 36b, 36c, 36d. The processor 11 further determines an operation signal 30c after determining that the first touch object, the second touch object and the third touch object are located on the sub-working surface 35a within the time interval T2. The transceiver interface 17 then transmits the operation signal 30c to the host, so that the host performs a second operation according to the operation signal 30c.

In addition to the aforementioned operations, the fourth embodiment can also perform all the operations and functions of the first and second embodiments, the only difference being that the touch detection module 33 of the fourth embodiment includes sub-touch detection modules 33a, 33b, and works The surface 35 comprises sub-surfaces 35a, 35b.

For the fifth embodiment of the present invention, please still refer to FIG. 3A , FIG. 3B , and FIG. 3C . The operations performed by the virtual navigation device 3 in the fifth embodiment are similar to those in the fourth embodiment, so only the differences between the two will be described in detail below.

In the fourth embodiment, after the navigation function of the virtual navigation device 3 has been operated, the user can perform more different operations only by adding at least one other touch object to move on another sub-working surface. However, in the fifth embodiment, after the navigation function of the virtual navigation device 3 has been operated, if the user wants to perform other additional operations, at least three other touch objects need to be added to move on another sub-working surface . In other words, in the fifth embodiment, each new operation requires at least three touch objects to move on the sub-working surface before it can be executed.

Specifically, the sub-touch detection module 33a detects a plurality of detection information 32a, 32b, 32c, 32d within the time interval T1, as shown in FIG. 3B. The processor 11 then determines that there are at least three touch objects (for example: the first touch object, the second touch object, and the third touch object) within the time interval T1 according to the detection information 32a, 32b, 32c, and 32d. The sub-working surfaces 35a are in contact. Afterwards, the processor 11 determines the movement information of each touch object according to the detection information 32a, 32b, 32c, 32d, and then determines the position information signal 30a according to the movement information. At this point, the navigation function of the virtual navigation device 3 is already in operation.

In the time interval T2 following the time interval T1, the sub-touch detection module 33b detects a plurality of detection information 34a, 34b, 34c, 34d, as shown in FIG. 3C. The processor 11 determines that a fourth touch object, a fifth touch object and a sixth touch object are located on the sub-working surface 35b within the time interval T2 according to the detection information 34a, 34b, 34c, 34d. After the processor 11 determines that the fourth touch object, the fifth touch object and the sixth touch object are located on the sub-working surface 35b, it determines an operation signal 30b. The transceiver interface 17 then transmits the operation signal 30b to the host, so that the host performs a first operation according to the operation signal 30b.

On the other hand, if the sub-touch detection module 33a detects a plurality of detection information 36a, 36b, 36c, 36d within the time interval T2. The processor 11 judges that the first touch object, the second touch object and the third touch object are located on the sub-working surface 35a within the time interval T2 according to the detection information 36a, 36b, 36c, 36d. The processor 11 further determines an operation signal 30c after determining that the first touch object, the second touch object and the third touch object are located on the sub-working surface 35a within the time interval T2. The transceiver interface 17 then transmits the operation signal 30c to the host, so that the host performs a second operation according to the operation signal 30c.

In addition to the aforementioned operations, the fifth embodiment can also perform all the operations and functions of the fourth embodiment. Those skilled in the art can directly understand how the fifth embodiment performs these operations and functions based on the above-mentioned fourth embodiment, so details are not repeated.

This navigation method is applicable to a virtual navigation device, such as the aforementioned virtual navigation devices 1 and 3, and the virtual navigation device includes a working surface, a touch detection module and a processor.

Firstly, step S401 is executed, and the touch detection module detects a plurality of first detection information within a first time interval. Then, step S403 is executed, and the processor judges that there are at least three touch objects (for example: the first touch object, the second touch object, and the third touch object) at the first time according to the first detection information. contact with the working surface in the interval. Afterwards, step S405 is executed, and the processor judges a piece of movement information of each touch object according to the first detection information. Afterwards, step S407 is executed, and the processor determines a location information signal according to the movement information.

If the virtual navigation device further includes a transceiver interface and the virtual navigation device is used to control a host, the navigation method can further execute step S409, in which the location information signal is sent to the host through the transceiver interface. In this way, the host can move a cursor on the screen according to the position information signal. In other implementations, if the virtual navigation device 1 includes a screen, or its touch detection module is a touch screen, the position information signal determined in step S407 can also be used to move the virtual navigation device on the screen. the cursor. In this type of implementation, since the virtual navigation device is not connected to an external host, step S409 can be omitted.

Moving to a second position, the second touch object moves from a third position to a fourth position on the work surface, and the third touch object moves from a fifth position to a sixth position on the work surface. In addition, step S407 can be completed through the process shown in FIG. 4B .

Specifically, in step S407a, a first distance between the first position and the second position is calculated by the processor. Next, step S407b is executed to calculate a second distance between the third position and the fourth position by the processor. Afterwards, step S407c is executed again, and a third distance between the fifth position and the sixth position is calculated by the processor. It should be noted that the execution order of steps S407a, S407b, and S407c can be reversed. Afterwards, step S407d is executed again, and an average value of the first distance, the second distance and the third distance is calculated by the processor. Next, in step S407e, the processor uses the average value of step S407d as the position information signal.

The position moves to a second position, the second touch object moves from a third position to a fourth position on the working surface, and the third touch object moves from a fifth position to a sixth position on the working surface. In addition, step S407 can be accomplished through the process shown in FIG. 4C .

Specifically, in step S407f, a first average value of the first position, the third position and the fifth position is calculated by the processor. After that, in step S407g, a second average value of the second position, the fourth position and the sixth position is calculated by the processor. Next, in step S407h, a difference between the second average value and the first average value is calculated by the processor. Thereafter, in step S407i, the processor uses the difference as a position information signal.

In some implementations, step S405 includes a step (not shown) of defining a polygon by the processor according to a plurality of positions where the at least three touch objects are in contact with the working surface. Step S405 further includes another step (not shown), the processor determines a change of an area of the polygon within the first time interval. After that, in step S407, the processor determines a moving direction and a moving distance contained in the position information signal according to the change of the area. The moving direction can enable the host to control a visual change effect or/and an auditory change effect, and the moving distance can enable the host to control the adjustment range of the aforementioned visual change effect or/and auditory change effect. The aforesaid visual change effect includes rotation, enlargement or/and reduction of a display area on the screen, wherein the display area displays a graph, a window or/and a cursor. The aforesaid hearing change effect includes a volume control, a sound effect selection or/and a sound effect mixing.

In some implementations, in step S405, the processor determines a movement track of each touch object on the work surface within the first time interval. Step S407 includes a step (not shown), the processor determines a moving direction included in the position information signal according to the moving trajectories. In addition, step S407 further includes a step (not shown) of calculating an average value of the moving trajectories by the processor as a moving distance included in the position information signal. Similarly, the moving direction can enable the host to control a visual changing effect or/and an auditory changing effect, and the moving distance can enable the host to control the adjustment range of the aforementioned visual changing effect and/or auditory changing effect.

After explaining various ways of determining the location information signal, the operation after step S409 will be described.
