  Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

  First, an electronic device according to an embodiment of the present disclosure will be described with reference to FIG. In the present embodiment, an example in which the electronic device is a mobile phone will be described. However, in the present embodiment, the electronic device is not limited to the mobile phone, and may be any electronic device such as a music player, a smartphone, a tablet, a portable personal computer, a digital camera, a media player, an electronic book reader, a navigator, and a game machine. It may be.

  As shown in FIG. 1, the electronic device 10 according to the present embodiment includes one or more physical keys 11, an operation pad 12, and a display unit 19.

  Each physical key 11 is provided to be able to be pressed in a direction (pressing direction) from the front surface to the back surface. For example, numbers or symbols may be printed on the surface of each physical key 11. The surface of each physical key 11 may be called a key top surface. In the present embodiment, the physical key 11 includes, for example, a dielectric such as a resin. For example, the relative dielectric constant of the resin contained in the physical key 11 may be 1 or more (for example, about 3). In the following description, an operation of pressing the physical key 11 is referred to as a pressing operation. In addition, the operation of releasing the pressed state of the physical key 11 by weakening the pressing on the pressed physical key 11 is also referred to as a release operation.

  The operation pad 12 is a user interface that receives a user operation on the electronic device 10 using a projected capacitive touch sensor 14 described later. In the present embodiment, a region (one-dot chain line in FIG. 1) surrounding one or more physical keys 11 in the case surface (appearance surface) of the electronic device 10 functions as the operation pad 12. The area functioning as the operation pad 12 includes the surface of the physical key 11. According to this configuration, it is possible to fit the physical key 11 and the operation pad 12 in a narrow area. Such a configuration is suitable, for example, for small devices such as mobile phones or mobile music players.

  For example, as shown in FIG. 2, one or more physical key sensors 13 capable of detecting an operation on each of one or more physical keys 11 (indicated by an alternate long and short dash line in the figure), as shown in FIG. And a touch sensor 14 capable of detecting an operation on the operation pad 12. For example, the one or more physical key sensors 13 and the touch sensor 14 are located on the substrate 15 in the pressing direction of the physical key 11 inside the housing of the electronic device 10.

  The touch sensor 14 is, for example, a projected capacitive sensor, and is provided in the vicinity of the physical key sensor 13 (and the physical key 11). Here, the proximity means that the distance between the physical key sensor 13 and the touch sensor 14 is close to the extent that the touch sensor 14 can detect, for example, a conductor (for example, a user's finger) pressing the physical key 11. In the present embodiment, for example, as shown in FIG. 2, the touch sensor 14 is disposed substantially adjacent to (for example, substantially adjacent to) each physical key sensor 13 so as to surround the periphery of the one or more physical key sensors 13. In other words, the touch sensor 14 is disposed on the substrate 15 so as to avoid the area where the one or more physical key sensors 13 are disposed.

  The projected capacitive touch sensor 14 includes a drive electrode (transmission antenna) and a reception electrode (reception antenna), and detects the capacitance between the drive electrode and the reception electrode. In the present embodiment, the capacitance detected by the touch sensor 14 can be, for example, a difference value between the capacitance at the time of execution of the calibration performed on a timely basis and the capacitance at the current time.

  For example, when a conductor such as a user's finger approaches the touch sensor 14, the capacitance detected by the touch sensor 14 increases. That is, the conductor approaching the touch sensor 14 has an effect of increasing the capacitance detected by the touch sensor 14. On the other hand, as described later, when the physical key 11 configured to include a dielectric such as a resin is pressed to approach the touch sensor 14, the capacitance detected by the touch sensor 14 decreases. That is, the dielectric approaching the touch sensor 14 has an effect of reducing the capacitance detected by the touch sensor 14.

  Therefore, when the physical key 11 is operated, the touch sensor 14 is affected by both the object pressing the physical key 11 and the physical key 11. The capacitance detected by the touch sensor 14 in response to the operation on the physical key 11 will be further described later.

  Next, with reference to FIGS. 3A and 3B, the positional relationship between the physical key 11 and the substrate 15 on which the physical key sensor 13 and the touch sensor 14 are provided will be described. In FIG. 3A and FIG. 3B, for simplification of the description, for example, other configurations such as a housing of the electronic device 10 and a holding member (for example, key rubber) that holds each physical key 11 so as to be pressed. The illustration of the elements is omitted.

  For example, as shown in FIG. 3A, the physical key 11 is integrally formed with a protrusion 16 projecting from the back surface. The substrate 15 on which the physical key sensor 13 and the touch sensor 14 are provided is disposed fixed to the housing of the electronic device 10 so as to face the back surface of the physical key 11.

  The physical key sensor 13 includes, for example, a disc spring 17 (for example, a metal dome) and a key switch 18. Further, the touch sensor 14 is provided substantially adjacent to the disc spring 17 on the radially outer side of the disc spring 17. Further, in the present embodiment, at least a part of the physical key 11 and the touch sensor 14 overlap with each other in the pressing direction of the physical key 11. Hereinafter, an area where at least a part of the physical key 11 and the touch sensor 14 overlap in the pressing direction is also referred to as an overlapping area.

  FIG. 3A shows a state (release state) in which the physical key 11 is not pressed. In the released state, the disc spring 17 is not deformed, and the key switch 18 is off. On the other hand, FIG. 3B shows a state in which the physical key 11 is pressed (pressed state). In the pressed state, the disc spring 17 is deformed by the load from the protrusion 16 of the physical key 11. The deformed disc spring 17 turns on the key switch 18. Then, when an object (for example, a user's finger) for pressing the physical key 11 is released from the physical key 11, the disc spring 17 elastically deforms and returns to the original state, for example, the state shown in FIG.

  Here, the relationship between the operation on the physical key 11 and the capacitance detected by the touch sensor 14 will be described. When the physical key 11 changes from the release state shown in FIG. 3A to the pressed state shown in FIG. 3B, the distance between the physical key 11 and the object pressing the physical key 11 and the touch sensor 14 It becomes short. At this time, the touch sensor 14 is affected by both the physical key 11 (dielectric) and an object on which the physical key 11 is pressed. Hereinafter, the reference value of the electrostatic capacitance which the touch sensor 14 detects is demonstrated as zero.

  FIG. 4 is a diagram showing the capacitance detected by the touch sensor 14 when the physical key 11 is pressed by the user's finger. FIG. 4 is a graph showing the x-axis and y-axis as positions on the touch sensor 14 and the z-axis as capacitance (detected value). When the physical key 11 is pressed by the user's finger, the touch sensor 14 is affected by the increase in capacitance from the conductor (user's finger) and decreases the capacitance from the dielectric (physical key 11). to be influenced. Here, compared with the influence by the physical key 11, the influence by the user's finger is dominant. For this reason, as shown, for example in FIG. 4, the electrostatic capacitance of a value (positive value) larger than a reference value is detected.

  The electronic device 10 according to the present embodiment can detect the operation on the touch sensor 14 as well as the detection of ON / OFF based on the pressing operation on the physical key 11. Specifically, in the present embodiment, the physical key 11 has a configuration that can be pressed. In the present embodiment, the physical key sensor 13 has a configuration capable of detecting an operation on the physical key 11. The physical key sensor 13 can detect, for example, the result of the operation on the physical key 11 as ON / OFF of the physical key 11. Further, in the present embodiment, the touch sensor 14 has a configuration capable of detecting the capacitance when the user's finger or the like approaches. For example, as shown in FIGS. 3 and 4, the touch sensor 14 can detect the capacitance when the physical key 11 is pressed.

  Therefore, in the present embodiment, the control unit 22 can determine the coordinates of the touch position (for example, the coordinates at which the capacitance becomes maximum) based on the capacitance detected by the touch sensor 14. Here, the touch position does not have to be the position directly touched by the user's finger on the touch sensor 14. In the present embodiment, the touch position may be, for example, a position on the touch sensor 14 corresponding to the position at which the user's finger is performing the pressing operation on the operation pad 12 including the physical key 11. In the present embodiment, for example, when an operation on the physical key 11 is detected, the control unit 22 can recognize a result detected by the touch sensor 14. Further, in the present embodiment, for example, even when an operation on the physical key 11 is not detected, a result detected by the touch sensor 14 when, for example, the user's finger approaches the operation pad 12 Can be recognized. Hereinafter, the determination of the coordinates by the control unit 22 based on the capacitance detected by the touch sensor 14 may be described as “the touch sensor 14 detects the coordinates” as appropriate.

  Next, a schematic configuration of the electronic device 10 will be described with reference to FIG. The electronic device 10 includes a physical key sensor 13, a touch sensor 14, a display unit 19, a communication unit 20, a storage unit 21, and a control unit 22.

  As described above, the physical key sensor 13 includes the disc spring 17 and the key switch 18, and can detect the operation (press operation and release operation) on the physical key 11. The physical key sensor 13 can also detect the state (pressed state and released state) of the physical key 11.

  The touch sensor 14 includes the drive electrode and the reception electrode as described above, and can detect the capacitance (or change in capacitance) between the drive electrode and the reception electrode. Hereinafter, as described above, the touch sensor 14 will be described on the assumption of a projected capacitive type. On the other hand, in the electronic device 10 according to the present embodiment, it is not essential that the finger of the user directly touches the touch sensor 14. Therefore, in the present embodiment, the touch sensor 14 may not necessarily detect direct touch of the user's finger or the like. For example, in the present embodiment, the touch sensor 14 may be a proximity sensor capable of detecting the position and degree of proximity of a user's finger or the like.

  The display unit 19 includes a display device such as a liquid crystal display or an EL display, for example, and can display various screens.

  The communication unit 20 is an interface for performing communication by connecting to, for example, a base station via wireless or wired communication.

  The storage unit 21 includes, for example, a primary storage device and a secondary storage device, and stores various information, programs, and the like necessary for the operation of the electronic device 10. The storage unit 21 can be configured by, for example, a semiconductor memory or a magnetic disk.

  The control unit 22 includes at least one processor, dedicated or general purpose, to provide control and processing capabilities to perform various functions, as will be described in more detail below. In particular, in the electronic device 10 according to the present embodiment, the control unit 22 executes various processes related to the touch sensor 14. For example, the control unit 22 acquires, from the touch sensor 14, information indicating the capacitance detected by the touch sensor 14.

  The number of processors provided in the control unit 22 is not limited to one, and may be plural. According to various embodiments, the at least one processor may also be implemented as a single integrated circuit (IC) or as a plurality of communicatively coupled integrated circuits IC and / or discrete circuits. Good. The at least one processor can be implemented in accordance with various known techniques.

  In one embodiment, a processor includes one or more circuits or units configured to perform one or more data calculation procedures or processes. For example, the processor may be one or more processors, controllers, microprocessors, microcontrollers, application specific integrated circuits (ASICs), digital signal processors, programmable logic devices, field programmable gate arrays, or any of these devices or configurations. The functions described below may be performed by including a combination or a combination of other known devices or configurations.

  In addition, the control unit 22 may appropriately execute calibration (automatic zero correction) of the touch sensor 14 based on the capacitance indicated by the acquired information. In the present embodiment, when the capacitance is less than the reference value (for example, a negative value), the control unit 22 sets the currently detected capacitance as the reference value. Specifically, when the detection value of the capacitance is “−10”, the control unit 22 performs calibration by increasing (+10) the detection value so that the detection value becomes “0”. Run the The calibration algorithm is not limited to the correction, and any algorithm that brings the detected value close to the reference value can be employed.

  Next, the concept of the operation of the electronic device 10 according to the present embodiment will be described.

  As described above, in the electronic device 10 according to the present embodiment, the physical key sensor 13 can detect an operation on the physical key 11 as ON / OFF of the physical key 11. In addition, as described above, the electronic device 10 according to the present embodiment can recognize the result detected by the touch sensor 14. Therefore, according to the electronic device 10 according to the embodiment of the present disclosure, by causing the physical key 11 and the touch sensor 14 to cooperate with each other, a highly convenient usage can be realized.

  On the other hand, in the electronic device 10, when the physical key 11 and the touch sensor 14 cooperate with each other, it is desirable that the electronic key 10 and the touch sensor 14 be properly matched with each other. In the present embodiment, when the physical key 11 and the touch sensor 14 cooperate with each other, they are properly matched with each other. Hereinafter, the concept of the operation of the present embodiment will be described more specifically.

  FIG. 6 is a diagram specifically illustrating the concept of the operation of the electronic device 10 according to the present embodiment. 6A shows a state (release state) in which the physical key 11 is not pressed, as in FIG. 3A. Further, FIG. 6 (b) shows a state (pressed state) in which the physical key 11 is pressed as in FIG. 3 (b).

  As shown in FIG. 6A, even if the physical key 11 is not pressed, the touch sensor 14 detects the coordinate T1 when the user's finger approaches. As shown in FIG. 6 (a), the touch sensor 14 has coordinates T1 at a position on the touch sensor 14 corresponding to the position where the user's finger is in contact with the physical key 11 (in this case, the belly of the user's finger). Is detected.

  Next, as shown in FIG. 6B, in a state where the physical key 11 is pressed, the touch sensor 14 detects the coordinate T2. As shown in FIG. 6B, the touch sensor 14 on the touch sensor 14 corresponds to the position where the finger is in contact with the operation pad 12 in a state where the user's finger presses the physical key 11. At the position, coordinate T2 is detected. Here, as shown in FIG. 6B, depending on the manner in which the user's finger presses the physical key 11, the coordinate position is shifted (from T1 to T2) in the state where the physical key 11 is pressed. It is detected. That is, as understood from the comparison of FIG. 6A and FIG. 6B, the position of the coordinates detected by the touch sensor 14 may be shifted before and after the physical key 11 is pressed. As described above, when the position of the coordinate detected by the touch sensor 14 is shifted before and after the physical key 11 is pressed, a problem may occur when the electronic device 10 performs the process of following the coordinate. .

  FIG. 7 is a diagram for explaining the position of the pointer displayed on the display unit 19 before and after the physical key 11 is pressed.

  For example, it is assumed that the electronic device 10 moves the pointer displayed on the display unit 19 based on the coordinates detected by the touch sensor 14. For example, as shown in FIG. 6A, in the state before the physical key 11 is pressed, the pointer P indicating the position S1 is displayed on the display unit 19 as shown in FIG. 7A. It is assumed that As described above, the electronic device 10 displays the pointer P at the corresponding position S1 (FIG. 7A) on the display unit 19 in correspondence with the coordinate T1 (FIG. 6A) detected by the touch sensor 14. .

  In such a situation, as shown in FIG. 6B, it is assumed that the physical key 11 is pressed. As described above, the coordinates T2 detected by the touch sensor 14 in FIG. 6B deviate from the coordinates T1 shown in FIG. 6A. That is, in the electronic device 10, the coordinates detected by the touch sensor 14 are shifted from T1 to T2. Therefore, the electronic device 10 moves the pointer P displayed on the display unit 19 from the position S1 to the position S2, as shown in FIG. 7B. Thus, in the electronic device 10, the position of the pointer P may be slightly shifted before and after the physical key 11 is pressed.

  As described above, although the position of the pointer P before the physical key 11 is pressed is S1, if the position of the pointer P after the physical key 11 is pressed is moved in S2, for example, A situation is assumed.

  For example, the user operates the operation pad 12 to move the pointer P, aligns the position of the pointer P with a predetermined icon displayed on the display unit 19, and then presses the physical key 11 to thereby perform the predetermined icon Assume a scene where you choose (or decide). In this case, the user brings the position of the pointer P to the predetermined icon and presses the physical key 11, but when the physical key 11 is pressed, the position of the pointer P moves to another (for example, adjacent) icon It is assumed that In this case, the electronic device 10 will select (or determine) another icon instead of the predetermined icon.

  In addition, when, for example, the screen of the Internet browser is displayed on the display unit 19, the user operates the operation pad 12 to scroll the screen in a predetermined direction (for example, up and down direction). Suppose. In this case, although the user has pressed the physical key 11 with the predetermined hyperlink selected, when the physical key 11 is pressed, another hyperlink is selected. is assumed. In this case, the electronic device 10 jumps to another hyperlink instead of the predetermined hyperlink.

  Furthermore, if the coordinates detected by the touch sensor 14 shift when the physical key 11 is pressed, there is a possibility that the electronic device 10 may recognize such an operation as an operation such as a slide or flick.

  In view of the above-described circumstances, the electronic device 10 according to the present embodiment controls the control unit 22 even if the coordinates detected by the touch sensor 14 shift before and after the physical key 11 is pressed. Not to be reflected in processing by. Hereinafter, the operation of the electronic device 10 according to the present embodiment will be described.

  FIG. 8 is a flowchart for explaining the operation of the electronic device 10 according to the present embodiment.

  At the time when the operation shown in FIG. 8 starts, in the electronic device 10, it is assumed that the physical key sensor 13 has not detected an operation on the physical key 11, and the touch sensor 14 has not detected any coordinates.

  When the operation illustrated in FIG. 8 starts, the control unit 22 determines whether the touch sensor 14 has detected coordinates (step S11). When it is not determined in step S11 that the coordinates are detected, the control unit 22 continues the process of step S11.

  If it is determined in step S11 that the coordinates are detected, the control unit 22 stores the detected coordinates (step S12). In step S12, the control unit 22 can store, for example, the detected coordinates in the storage unit 21. Further, in step S12, the control unit 22 may store the detected coordinates in, for example, a cache memory in the control unit 22, or may store it in any external storage device. Thus, in the present embodiment, the control unit 22 stores data detected by the touch sensor 14.

  After storing the coordinates in step S12, the control unit 22 determines whether the physical key sensor 13 has detected an operation on the physical key 11 (step S13). In short, in step S13, it is determined whether the user has pressed the physical key 11 or not.

  If it is determined in step S13 that the operation on the physical key 11 has not been detected, the control unit 22 determines whether a predetermined time has elapsed since the touch sensor 14 has started detecting coordinates (step S14). In step S14, instead of determining whether or not a predetermined time has elapsed since the touch sensor 14 started detecting the coordinates, the control unit 22 performs a predetermined process after the touch sensor 14 starts detecting the coordinates. It may be determined whether or not the number of times and coordinates have been detected.

  If it is determined in step S14 that the predetermined time has not elapsed, the control unit 22 returns to step S11 and continues the process. Also, if it is determined in step S14 that the coordinates have not been detected a predetermined number of times, the process returns to the control unit 22 and continues.

  When the pressing operation on the physical key is not detected in step S13 and the predetermined time has not elapsed in step S14, the control unit 22 repeats the processing from step S11 to step S14. Each time the processing from step S11 to step S14 is repeated, coordinates are stored in step S12. Therefore, by repeating the processing from step S11 to step S14, coordinate data is accumulated. Such accumulation of coordinate data may be stored in the storage unit 21 or may be stored in, for example, a cache memory in the control unit 22 or may be stored in any external storage device. Hereinafter, accumulation of such coordinate data will be described as being stored in the storage unit 21.

  FIG. 9 is a diagram showing an example of accumulation of coordinate data stored in the storage unit 21. As shown in FIG.

  As shown in FIG. 8, in the present embodiment, the control unit 22 stores the coordinates detected by the touch sensor 14 in the storage unit 21 each time the process of step S12 is performed. Therefore, as shown in FIG. 9, the coordinates detected by the touch sensor 14 are accumulated in the storage unit 21.

  FIG. 9 shows how the first detected coordinates (x01, y01) are stored in the storage unit 21 when the coordinates first detected by the touch sensor 14 in step S11 are (x01, y01). . Next, when the coordinates detected by the touch sensor 14 in step S11 are (x02, y02), the second detection coordinates are stored in the (x02, y02) storage unit 21. The same applies to the coordinates detected from the third time onwards.

  The time interval of the detection of such coordinates can be set variously according to the operation that the electronic device 10 should perform. As an example, when repeating the process from step S11 to step S14, one cycle can be made into about 10 ms. In this case, for example, when 10 times of detection of coordinates are accumulated, it takes about 100 ms. Hereinafter, an example in this case will be described.

  In the case of the example described above, the predetermined time in step S14 is 100 ms, and the predetermined number of detections represents 10 times. That is, in an example of the present embodiment, in step S14, the control unit 22 returns to step S11 and continues the process until 100 ms or until the tenth time since the touch sensor 14 first detected the coordinates. In this case, when the touch sensor 14 detects the coordinates in step S11, the control unit 22 stores (accumulates) the coordinates detected by the touch sensor 14 in step S12.

  On the other hand, in the example of the present embodiment, when the touch sensor 14 first detects coordinates in step S14 and reaches 100 ms or the tenth time, the control unit 22 performs the process of the next step S15.

  In step S15, the control unit 22 executes a process based on accumulation of the coordinates detected by the touch sensor 14 (step S15). That is, in step S <b> 15, when the pressing operation on the physical key 11 is not detected, the control unit 22 performs processing based on the coordinates detected by the touch sensor 14. This process may be an operation for moving the pointer displayed on the display unit 19 based on the coordinates detected by the touch sensor 14 as described in FIG. 7A, for example. Therefore, according to the electronic device 10 according to the present embodiment, when the pressing operation on the physical key 11 is not detected, processing based on the operation on the touch sensor 14 is performed. Therefore, when the user does not press the physical key 11, the user can freely move the pointer displayed on the display unit 19 by, for example, an operation such as sliding a finger on the operation pad 12.

  As described above, in the present embodiment, when the control unit 22 stores data detected by the touch sensor 14 for a predetermined time or a predetermined number of times without detecting an operation on the physical key 11, processing based on the stored data is performed. May be performed.

  In step S15, when executing processing based on accumulation of coordinates detected by the touch sensor 14, the control unit 22 can use accumulation of the detected coordinates in various manners. For example, the control unit 22 may sequentially process all the coordinates of the accumulation of detected values (for example, the first to tenth detections) (first to tenth in a row). Also, for example, the control unit 22 may perform some (for example, 2, 4, 6, 8, or 10 times) of accumulation of detected values (for example, 1 to 10 times of detection times), for example, 5 or 10 times Etc.) may be extracted and processed. Also, for example, the control unit 22 may process only the coordinates (in this case, only the tenth time) stored last in the accumulation of detected values (for example, the first to tenth times of detection).

  In addition, when performing processing based on accumulation of coordinates detected by the touch sensor 14 in step S15, the control unit 22 performs predetermined processing on accumulation of the detected coordinates and then uses it in various modes. May be For example, the control unit 22 may perform processing based on the coordinates after averaging the coordinates detected from the first time to the tenth time and processing the coordinates into one coordinate. Specifically, for example, the control unit 22 may simply add the x coordinate and the y coordinate of ten coordinates, respectively, and divide the sum by 10 to perform averaging. In addition, the control unit 22 may extract, for example, coordinates closest to the middle value from among ten coordinates.

  As described above, in the present embodiment, the control unit 22 may perform a process based on the data subjected to the predetermined process after performing the predetermined process on at least a part of the stored data (step S15). In the present embodiment, it may be assumed that the coordinates detected by the touch sensor 14 vary, for example, before and after the pressing operation on the physical key 11 is performed. However, as described above, by averaging the accumulated coordinates, when performing processing based on the coordinates thereafter, the control unit 22 can perform a smooth and continuous operation with less fluctuation.

  In the example of the present embodiment described above, when repeating the process of step S15 following step S14, one cycle can be set to 100 ms. That is, in the present example, when the operation on the physical key 11 is not detected, the control unit 22 performs processing based on accumulation of coordinates detected by the touch sensor 14 every 100 ms (step S15).

  Thus, in the present example, when the operation on the physical key 11 is not detected, the control unit 22 is based on the accumulation of the coordinates until the coordinates are accumulated for 100 ms (or for 10 times of detection). Do not process. Therefore, in the present example, since the process of step S15 is performed after 100 ms (or 10 times of detection), the process based on the coordinates detected by the touch sensor 14 is performed with a slight delay. .

  However, in the present example, this delay is at most 100 ms, which is not recognized in the normal operation of the user, and hardly causes a problem. Further, as shown in FIG. 1 and FIG. 2, in the electronic device 10 according to the present embodiment, the touch sensor 14 and the display unit 19 are not overlapped and disposed, but are disposed at different positions. Therefore, even if the timing at which the movement of the user's finger detected by the touch sensor 14 is reflected on the display of the display unit 19 is delayed by about 100 ms, it is considered that it is not noticeable to most users.

  When the process based on the coordinates is performed in step S15, the control unit 22 returns to step S11 and continues the process. In this case, when the touch sensor 14 detects the coordinates in step S11, the control unit 22 stores (accumulates) the coordinates detected by the touch sensor 14 in step S12.

  After performing the process based on the coordinates in step S15, the control unit 22 may erase the coordinates detected by the touch sensor 14 accumulated so far before returning to step S11. In particular, after step S15, if the coordinates accumulated up to that point are not used, there is no point in maintaining this. Also, in the case where the coordinates detected by the touch sensor 14 are to be accumulated in the future, the accumulation of the coordinates will continue to increase unless they are erased at an appropriate timing. Therefore, after step S15, in the case where the coordinates accumulated so far are not used, it is preferable that the control unit 22 erase the coordinates accumulated so far before returning to step S11.

  On the other hand, when the pressing operation on the physical key is detected in step S13, the control unit 22 executes the process of step S16.

  In step S16, the control unit 22 does not execute the process based on the accumulation of the coordinates detected by the touch sensor 14 (step S16). That is, in step S16, when the pressing operation on the physical key 11 is detected, the control unit 22 does not execute the process based on the coordinates detected by the touch sensor 14. As described above, in the present embodiment, when the physical key sensor 13 detects an operation on the physical key 11, the control unit 22 controls not to execute processing based on data detected by the touch sensor 14.

  Therefore, in the present embodiment, for example, as shown in FIGS. 6A and 6B, it is assumed that the coordinates detected by the touch sensor 14 are shifted from T1 to T2 before and after the pressing operation on the physical key 11 Also, processing based on this deviation is not performed. Therefore, in the present embodiment, when the pressing operation on the physical key 11 is detected, the display unit 19 is displayed based on the coordinates detected by the touch sensor 14 as shown in FIG. 7B, for example. The pointer never shifts. That is, in the present embodiment, when the pressing operation on the physical key 11 is detected, even if the coordinates detected by the touch sensor 14 shift from T1 to T2, as shown in FIG. 7A, for example, the display unit The pointer P displayed at 19 remains at the position S1.

  In step S16, it is preferable that the control unit 22 execute a process based on the pressing operation on the physical key 11, instead of not executing the process based on the accumulation of the coordinates detected by the touch sensor 14. In step S13, since the user performs the pressing operation on the physical key 11, it is considered that the user is expected to execute predetermined processing in response to the pressing operation. Therefore, in this case, the control unit 22 is preferably controlled to execute a predetermined process assigned to the pressing operation of the physical key 11.

  For example, in response to the pressing operation of the physical key 11, the control unit 22 may activate an application program assigned to the icon pointed by the pointer P (before the shifted coordinates are detected). Also, for example, the control unit 22 may jump to the selected hyperlink (before the shifted coordinates are detected) according to the pressing operation of the physical key 11. As described above, the predetermined process assigned to the pressing operation of the physical key 11 can be defined in an application program or the like activated in the electronic device 10.

  When the process based on the accumulation of the coordinates detected by the touch sensor 14 in step S16 is not performed, the control unit 22 deletes the coordinates detected by the touch sensor 14 accumulated so far or invalidates the coordinates. It is also good. In particular, after step S16, if the coordinates accumulated up to that point are not used, there is no point in maintaining this. Also, in the case where the coordinates detected by the touch sensor 14 are to be accumulated in the future, the accumulation of the coordinates will continue to increase unless they are erased at an appropriate timing. Therefore, after step S16, if the coordinates accumulated so far are not used, it is preferable that the control unit 22 erase the coordinates accumulated so far before the operation shown in FIG. 8 is finished.

  As described above, according to the electronic device 10 according to the present embodiment, when the pressing operation on the physical key 11 is detected, even if the coordinates detected by the touch sensor 14 deviate, processing based on the deviation is executed. I will not. Therefore, according to the electronic device 10, although the user has adjusted the position of the pointer P to the desired icon and pressed the physical key 11, when the physical key 11 is pressed, the position of the pointer P is different (for example, adjacent) The risk of moving over the icon is reduced. For this reason, according to the electronic device 10 according to the present embodiment, the risk of selecting (or determining) another icon other than the icon desired by the user is reduced.

  Further, according to the electronic device 10 according to the present embodiment, when the physical key 11 is pressed while the user presses the physical key 11 in a state where the predetermined hyperlink is selected on the Internet browser, another hyper The risk of the link being selected is reduced. Therefore, according to the electronic device 10 according to the present embodiment, the risk of jumping to another hyperlink instead of the hyperlink desired by the user is reduced.

  Furthermore, according to the electronic device 10 according to the present embodiment, such an operation is recognized as an operation such as a slide or a flick even if the coordinates detected by the touch sensor 14 deviate when the physical key 11 is pressed. Reduce the risk of

  Therefore, according to the electronic device 10 according to the present embodiment, by causing the physical key 11 and the touch sensor 14 to cooperate with each other, it is possible to realize a highly convenient usage.

In addition, the embodiment of the present disclosure can also be implemented as a control program of an electronic device that is executed by an electronic device including a physical key and a touch sensor.

  The electronic device 10 according to the embodiment described above exemplifies a configuration in which the pressing operation is detected based on the fact that the disc spring 17 is deformed and the key switch 18 is turned on. Moreover, the electronic device 10 which concerns on the above-mentioned embodiment illustrated the structure which detects release operation based on the disc spring 17 returning to the original state and the key switch 18 becoming OFF. However, the electronic device according to the embodiment of the present disclosure is not limited to such a configuration. For example, the electronic device 10 may include a touch sensor located below the disc spring 17 instead of the key switch 18, and the electrodes of the touch sensor may be coupled when the disc spring 17 is deformed. In this case, the electronic device 10 may detect the pressing operation based on the fact that the disc spring 17 is deformed and the electrodes of the touch sensor are connected. Also, in this case, the electronic device 10 may detect the release operation based on the fact that the disc spring 17 returns to the original state and the coupling between the electrodes is released.

  In the embodiment described above, when the control unit 22 stores data detected by the touch sensor 14 for a predetermined time or a predetermined number of times without detecting an operation on the physical key 11, processing based on the stored data is performed. The configuration to be implemented is illustrated. However, the electronic device according to the embodiment of the present disclosure is not limited to such a configuration. For example, when an operation on the physical key 11 is not detected, and the data detected by the touch sensor 14 is continuously stored for a predetermined time or a predetermined number of times, the control unit 22 executes a process based on the stored data. May be That is, when the detection by the touch sensor 14 is stopped before the accumulation of data detected by the touch sensor 14 reaches a predetermined time or a predetermined number of times, the control unit 22 resets the accumulation of data stored so far. Good. Here, that the detection by the touch sensor 14 is stopped may be, for example, a case where a state without detection by the touch sensor 14 continues for a predetermined time. As processing in such a case, for example, when the electronic device 10 is operating according to the flowchart shown in FIG. 8, when the process proceeds to No in step S14, the coordinates accumulated so far are erased before returning to step S11.
