Description

The present invention relates to a touch panel controller and program.

Conventionally, there has been known a technique capable of preventing erroneous input of touch operations. For example, in Patent Document 1, a low-sensitivity region is set between buttons displayed on a touch panel to prevent erroneous input. In Japanese Patent Application Laid-Open No. 2002-200000, an erroneous input is prevented by changing the boundary for identification according to the touched position and identifying the input by the next touch based on the changed boundary. In Patent Document 3, an intermediate band is provided between two icon areas that does not reflect changes in icon selection states.

A plurality of buttons are arranged adjacently like a keyboard, and if a finger slips during operation of a touch panel, it may move to an adjacent button other than the target button. In particular, when there is no area between buttons or when the area between buttons is small, the finger may move to an adjacent button other than the target button, and it is not always possible to prevent erroneous touch operation input. There is a task that cannot be done.

An object of the present invention is to provide a touch panel controller and a program capable of preventing erroneous touch operation input.

To achieve the above object, the touch panel controller disclosed in the specification includes detection means for detecting a touch position, touch-on and touch-off; acquisition means for acquiring an operation level of an object corresponding to the touch position; When the current operation level and the previous operation level acquired by the means have a predetermined relationship, the coordinate information of the position having the predetermined relationship is output to an external device as the touch-off coordinate information, and the detection means detects the and output control means for not outputting the coordinate information of the touch position detected by the detection means to the external device until touch-off is detected.

According to the present invention, erroneous input of touch operation can be prevented.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram of an information processing device including a touch panel and a main device. An information processing apparatus 10 of FIG. 1 includes a touch panel 1 having a display function and a key input function, and a main device 5 for processing input data. The information processing device 10 is a device having a touch panel, and is, for example, a personal computer, a server, a smartphone, a home appliance (including a refrigerator, a washing machine, etc.), a kiosk terminal, an ATM, or the like.

The touch panel 1 includes a controller 2 that detects the position of touch input and executes various processes. The controller 2 has a memory 3 that stores programs and data for executing various processes and functions as a working area for executing the programs. The controller 2 functions as detection means, acquisition means and output control means, and the memory 3 functions as storage means. Although not shown, the touch panel 1 includes a substrate, a transparent conductive film, and the like. The controller 2 may be detachably attached to the touch panel 1 or may be fixed to the touch panel 1 .

The main device 5 receives various data from the touch panel 1 and executes various processes. The main device 5 includes a CPU (Central Processing Unit) 6 connected to the controller 2 via a USB cable 8, and a memory 7 for storing programs, applications and data. Note that the main device 5 may be provided with a processor, a dedicated arithmetic IC or an ASIC (Application Specific Integrated Circuit), etc., instead of the CPU 6 .

FIG. 2 is a diagram showing an example of an application displayed on the touch panel 1. As shown in FIG. Application 11 is stored in memory 7 and executed by CPU 6 . The application 11 screen has a background 12 , a display area 13 and a plurality of buttons 14 . Buttons 14 in FIG. 2 are numeric keys or the like. The background 12, the display area 13, and the button 14 are objects, and each object has an operation level. The operation level associated with each object can be changed by the application 11, for example. The application 11 is not limited to the calculator application as shown in FIG.

FIG. 3 is a diagram showing the relationship between objects, area information, and operation levels. For example, as shown in FIG. 3, the application 11 has table data that associates each object, area information, and operation level. The area information is data indicating the area corresponding to the object. For example, the data of the area corresponding to the button 14 is the coordinates (X1, Y1) (X2, Y1) (X1, Y2) corresponding to the four corners of the button 14. It is set as (X2, Y2).

Upon detecting the coordinate information of the touch position, the controller 2 inquires of the CPU 6 about the operation level of the object corresponding to the touch position. Upon receiving the coordinate information of the touch position from the controller 2, the CPU 6 specifies the operation level of the object corresponding to the touch position based on the table data of FIG.

The controller 2 may acquire the table data of FIG. 3 from the CPU 6 in advance and store it in the memory 3 . In this case, when the controller 2 detects the coordinate information of the touch position, the controller 2 can acquire the operation level of the object corresponding to the touch position using the table data stored in the memory 3 without querying the CPU 6 .

FIG. 4A is a diagram showing a first example of a touch operation on an object, and FIG. 4B is a diagram showing operation levels set for the object in FIG. 4A. FIG. 4(C) is a diagram showing a second example of touch operation on an object, and FIG. 4(D) is a diagram showing operation levels set for the object in FIG. 4(C). FIG. 4(E) is a diagram showing a third example of a touch operation on an object, and FIG. 4(F) is a diagram showing operation levels set for the object in FIG. 4(E). FIG. 4(G) is a diagram showing a fourth example of touch operation on an object, and FIG. 4(H) is a diagram showing operation levels set for the object in FIG. 4(G).

4(A), 4(C), 4(E) and 4(G), the movement of the operator's finger is indicated by arrows, and the operator's finger moves to the button 14a, background 12 and Slide on the button 14b object.

In FIGS. 4A and 4B, the same operation level 1 is set for all objects of button 14a, background 12 and button 14b. When the operation levels of adjacent objects are the same, the touch operation is not restricted and can be freely operated. When the operator's finger slides over the objects of the button 14a, the background 12, and the button 14b, the controller 2 sequentially outputs the coordinate information of the respective touch positions of the button 14a, the background 12, and the button 14b to the CPU 6, and the button 14a. And when information and functions are set in the button 14b, the inputs of the buttons 14a and 14b are enabled. The operation level can be set from high level "5" to low level "0", but is not limited to these numerical values.

In FIGS. 4C and 4D, operation levels 5, 3, and 1 are set for the button 14a, background 12, and button 14b objects, respectively. When the operation level of the object changes from high level to low level, the touch operation is not restricted, and when the operator's finger slides over the objects of the button 14a, the background 12 and the button 14b, the controller 2 The coordinate information of each touch position of the button 14a, the background 12 and the button 14b is output to the CPU 6 in order.

When the operation level of an object shifts from a low level to a high level, touch operations may be restricted and free operations may not be possible.

In FIGS. 4(E) and 4(F), operation levels 1, 2, and 3 are set for the objects of button 14a, background 12, and button 14b, respectively. If the difference in operation level between adjacent objects is equal to or less than a predetermined value (eg, 1), touch operations are not restricted. In FIGS. 4E and 4F, even if the finger moves from the button 14a to the background 12 or from the background 12 to the button 14b, the operation level difference between the adjacent objects is 1. , touch operation is not restricted.

On the other hand, in FIGS. 4(G) and 4(H), operation levels 1, 3, and 1 are set for the objects of button 14a, background 12, and button 14b, respectively. When the finger moves from the button 14a to the background 12, the finger moves from a low-level object to a high-level object, and the difference between the operation levels set between the button 14a and the background 12 is 2. Operation is restricted. Specifically, when the finger moves outside the button 14a, the controller 2 outputs to the CPU 6 the coordinates of the point P in FIG. After that, the controller 2 does not output to the CPU 6 the coordinate information of the background 12 and the touch position of the button 14b. Therefore, only the input to the button 14a is valid, and the input to the background 12 or the button 14b is invalid. In this way, when the operation level of an object transitions from a low level to a high level, and the difference in operation level between adjacent objects is 2 or more, the controller 2 simultaneously moves the finger to the high-level object. The coordinate information of the position where the difference in operation level exceeds a predetermined value is output to the CPU 6 as touch-off coordinates, and thereafter, even if the finger moves to an object of the same level or a lower level, the coordinate information of the touch position is sent to the CPU 6. No output.

As described above, in the present embodiment, when the operation level of an object transitions from a low level to a high level, or when the difference in operation level between adjacent objects is equal to or less than a predetermined value, the touch operation is not restricted. When the operation level of an object changes from a low level to a high level and the difference between the operation levels of adjacent objects exceeds a predetermined value, the touch operation is restricted until touch-off is detected when the finger leaves the touch panel. operation is disabled.

In this embodiment, if the operation level of an object changes from a low level to a high level and the difference in operation level between adjacent objects exceeds a predetermined value, the touch operation is restricted. It is not limited to this. For example, touch operations may be restricted when the operation level of an object transitions from a high level to a low level and the difference in operation level between adjacent objects exceeds a predetermined value. The conditions for restricting the touch operation can be appropriately changed by setting the application 11, setting the table data in FIG. 3, or the like.

FIG. 5 is a flowchart showing touch input processing executed by the controller 2. As shown in FIG.

The controller 2 determines whether touch-on is detected by monitoring the voltage applied to the touch panel 1 (S1). When touch-on is detected (YES in S1), the controller 2 determines whether or not touch-off coordinate information, which will be described later, has already been output to the CPU 6 (S2). If the touch-off coordinate information has already been output to the CPU 6 (YES in S2), the procedure returns to S1.

If the touch-off coordinate information has not been output to the CPU 6 (NO in S2), the controller 2 detects the coordinates of the touch position on the touch panel 1 (S3). The controller 2 outputs coordinate information of the detected touch position to the CPU 6, and acquires the operation level of the object corresponding to the touch position from the CPU 6 (S4). If the table data is stored in the memory 3 in advance, the controller 2 may use the table data in the memory 3 to acquire the operation level of the object corresponding to the touch position without inquiring the CPU 6 .

The controller 2 determines whether or not the previously determined operation level is 0 (S5). When the touch panel 1 is not touched, the operation level is set to 0 for convenience. On the other hand, if the touch panel 1 has already been touched, the operation level of the previously touched object is set. If the previous operation level is 0 (YES in S5), the controller 2 outputs coordinate information of the current touch position to the CPU 6 (S7). Since the memory 3 holds the operation level of the previous touch position and the operation level of the current touch position, the controller 2 updates the operation level of the previous touch position and the operation level of the current touch position. The updated operation level is held in the memory 3 (S8). Then, the procedure returns to S1.

On the other hand, if the previous operation level is not 0 (NO in S5), the controller 2 determines whether the operation level of the previous touch position is equal to or higher than the operation level of the current touch position (S6). In S6, for example, it is determined whether the operation level increases or decreases when the finger moves from a certain object to an adjacent object (see FIGS. 4A to 4H). If the operation level of the previous touch position is equal to or higher than the operation level of the current touch position (YES in S6), the procedure proceeds to S7, and the coordinates of the current touch position are output to the CPU 6 assuming that the touch input is valid. do. When the finger moves from a certain object to an adjacent object, if the operation level of the object is constant or decreases between this time and the previous time, the processing is YES in S6→S7, and the touch operation is not restricted.

On the other hand, if the operation level of the previous touch position is lower than the operation level of the current touch position (NO in S6), the controller 2 determines the difference between the operation level of the previous touch position and the operation level of the current touch position. It is determined whether or not the difference is equal to or less than a predetermined value (S9). When it is determined NO in S6, since the operation level has increased, it is determined in S9 whether the amount of increase in the operation level is equal to or less than a predetermined value as shown in FIG. 4(F) or by a predetermined value as shown in FIG. It is determined whether the

If the difference between the operation level of the previous touch position and the operation level of the current touch position is equal to or less than the predetermined value (YES in S9), the procedure proceeds to S7. For example, when the finger moves from a given object to an adjacent object, the touch operation is not restricted if the operation level increases but the difference in operation level is judged to be less than a predetermined value in the processing of YES in S9→S7.

If the difference between the operation level at the previous touch position and the operation level at the current touch position exceeds a predetermined value (NO in S9), the controller 2 invalidates the touch input, and the difference in operation level reaches the predetermined value. The coordinate information of the position exceeding the value is output to the CPU 6 as touch-off coordinates (S10). For example, when the operation level increases beyond a predetermined value as a result of moving the finger from a given object to an adjacent object, the controller 2 determines the coordinates of the position where the operation level exceeds the predetermined value in the processing from NO in S9 to S10. The information is output to the CPU 6 as touch-off coordinate information. Then, the controller 2 clears the operation level of the previous touch position and the operation level of the current touch position held in the memory 3 to 0 (S11). Then, the procedure returns to S1.

Returning to S1, when the touch-on state is detected (YES in S1), if the touch-off coordinate information has already been output to the CPU 6 in S10 (YES in S2), the procedure returns to S1 again. After the controller 2 outputs touch-off coordinate information to the CPU 6 in FIG. is not output to the CPU 6.

If touch-on is not detected in S1, in other words, if the finger has left the touch panel or the touch panel has not yet been touched (NO in S1), the controller 2 has output touch-off coordinate information to the CPU 6 in S10. (S12). If the touch-off coordinate information has already been output to the CPU 6 in S10 (YES in S12), the controller 2 clears the touch-on and touch-off output information in the memory 3 (S14), and the procedure returns to S1. In the process of S14, in order to prepare for a new touch input, information such as information indicating that touch-off coordinate information has been output to the CPU 6 is cleared from the memory 3. FIG.

On the other hand, if the touch-off coordinate information has not been output to the CPU 6 (NO in S12), the controller 2 determines whether or not the touch position coordinate information has been output to the CPU 6 (S13). If the coordinate information of the touch position has already been output to the CPU 6 (YES in S13), the procedure proceeds to S10, and the coordinates of the touch position when the touch-off is determined in S1 is output to the CPU. YES in S13→S10, for example, when the finger is lifted from the button 14a without sliding, the controller 2 outputs the coordinate information of the finger lifted position to the CPU 6 as touch-off coordinates. If the coordinate information of the touch position has not been output to the CPU 6 (NO in S13), the procedure returns to S1. If the processing of NO in S13→S1 loops, it means that the touch input has not yet been performed.

As described above, according to the present embodiment, the controller 2 detects touch positions, touch-on and touch-off (S1, S3), and acquires the operation level of the object corresponding to the touch positions (S4). Then, when the current operation level and the previous operation level reach a predetermined relationship, the coordinate information of the position where the predetermined relationship is established is output to the CPU 6 as touch-off coordinate information (S10). Until a touch-off is detected, the coordinate information of the touch position where the touch-on is detected in S1 is not output to the CPU 6 (YES in S1→YES in S2→S1).

Therefore, if the operator appropriately sets the operation level of the target button and the operation levels of other adjacent buttons, even if the finger slips and moves to a button other than the target button, , the coordinate information of the touch position of the destination button is not output to the CPU 6 . Therefore, erroneous input of touch operation can be prevented. Further, when the current operation level and the previous operation level do not have a predetermined relationship, the touch operation is not restricted, and free operation is possible.

Further, in the present embodiment, it is possible not only to prevent erroneous input but also to restrict input. By setting an operation level for an object according to its purpose, it is possible to implement an operation that prevents erroneous input or an operation that allows input only in a fixed order. For example, five buttons [0] to "4" are arranged in a line from left to right, and operation levels 1 to 5 are set for the five buttons [0] to "4", respectively. When the operation level 5 is high level and the operation level 1 is low level, and the operation level shifts from low level to high level, it is assumed that touch operation is restricted and free operation cannot be performed. In this case, even if the user's finger touches the button [0] and moves it to the right, the buttons [1] to "4" cannot be input. On the other hand, if the user's finger touches button [4] and moves it to the left, it is possible to input buttons [0] to "3".

It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.
