Description

  The present invention relates to an electronic device, an input processing method, and a program.

  In recent years, communication terminal devices having a touch panel have become widespread. Such a communication terminal device includes an input device that performs input by operating a touch panel with a human finger or the like.

  Conventionally, there are various methods as an input method for a touch panel. Among these, in an input device using the capacitive coupling method, which is the main method, an operation for making an input by physically touching (touching) the touch panel (hereinafter referred to as “touch input operation”), and a touch panel An operation for displaying a menu or the like on the touch panel (hereinafter referred to as “hover operation”) can be performed in the vicinity of the touch panel. Whether the touch panel is touched or close can be determined based on a change in the capacitance of the touch panel.

  On the other hand, in the input device using the capacitive coupling method, when the user touches the touch panel through a glove, since the glove is non-conductive and the change in the capacitance is small, the touch panel is generally touched. Therefore, touch input operation cannot be performed. However, since the user may actually operate the touch panel through a glove, it is preferable that a touch input operation can be performed even when the user touches the touch panel through a glove.

  2. Description of the Related Art Conventionally, an input device that switches between a touch input operation mode with a bare hand and a touch input operation mode with a glove when releasing the lock state of the touch panel screen is known. In this input device, a touch input operation can be performed via a glove. However, with this input device, every time the mode is switched, the screen needs to be once locked, and there is a problem in that it is not easy to use.

  Conventionally, an input device that automatically switches between a touch input operation mode with bare hands and a touch input operation mode with gloves is known (for example, Patent Document 1). In the input device of Patent Literature 1, two sensor output threshold values, a first sensor output threshold value and a second sensor output threshold value, are provided. When the sensor output is less than the first sensor output threshold value, the touch input operation is performed with bare hands. If the sensor output is greater than or equal to the first sensor output threshold and less than the second sensor output threshold, it is determined that the touch input operation is performed with a glove.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

“Embodiment 1”
<Configuration of input device>
A configuration of input device 100 according to Embodiment 1 of the present invention will be described with reference to FIG.

  The input device 100 mainly includes a touch panel layer 101, a coordinate acquisition unit 102, a press sensor 103, a press acquisition unit 104, a state determination unit 105, a touch coordinate processing unit 106, and a hover coordinate processing unit 107. Has been.

  The touch panel layer 101 is a capacitively coupled touch panel layer having a display function. The touch panel layer 101 has a plurality of electrodes (not shown) arranged in parallel to two directions (X direction and Y direction) orthogonal to each other. The touch panel layer 101 forms a capacitor at the intersection of electrodes orthogonal to each other. The touch panel layer 101 changes the capacitance of the capacitor according to the position where the external object exists and the distance to the external object, and the coordinate acquisition unit 102 receives signals of different strengths from the electrodes according to the change in capacitance. Output to. Here, the external object is a human hand or a human hand wearing gloves.

  The coordinate acquisition unit 102 detects the coordinates touched by the external object or the coordinates approached by the external object based on the intensity of the signal output from each electrode of the touch panel layer 101.

  The coordinate acquisition unit 102 determines the state of the external object based on the intensity of the signal output from each electrode of the touch panel layer 101. Specifically, the coordinate acquisition unit 102 determines a contact state in which an external object touches the touch panel layer 101 and a proximity state in which the external object exists in a proximity region within a predetermined distance from the touch panel layer 101.

  For example, the coordinate acquisition unit 102 determines that the signal is in the proximity state when the signal strength is greater than or equal to the threshold S1 and less than the threshold S2 (threshold S1 <threshold S2). Further, the coordinate acquisition unit 102 determines that the contact state is established when the signal strength is equal to or greater than the threshold value S2. Further, the coordinate acquisition unit 102 determines that neither the contact state nor the proximity state is present when the intensity of the signal is less than the threshold value S1.

  The coordinate acquisition unit 102 outputs the coordinate detection result and the determination result of the state of the external object (hereinafter referred to as “state determination result”) to the state determination unit 105.

  In the present embodiment, the coordinate acquisition unit 102 determines the contact state and the proximity state based on the change in capacitance. However, the proximity state is determined by infrared reflection detection, ultrasonic wave detection, and the like. It is also possible to perform reflection detection or image analysis by a camera (including 3D image analysis by a plurality of cameras).

  The pressure sensor 103 is stacked on the touch panel layer 101. The press sensor 103 outputs a voltage value that changes according to the external pressing force to the press acquisition unit 104. The pressure sensor 103 is a piezoelectric element, for example. Note that the pressure sensor 103 only needs to detect that a load is applied to the touch panel layer 101, and is not necessarily stacked on the touch panel layer 101. For example, the pressure sensor 103 may be disposed on the entire or part of the back surface of the touch panel layer 101 (more specifically, one side or four corners of the four sides) or a casing on which the touch panel layer 101 is fixed. .

  The press acquisition unit 104 detects a press on the touch panel layer 101 based on the voltage value input from the press sensor 103. For example, the pressure acquisition unit 104 detects a pressure when the voltage value input from the pressure sensor 103 or the cumulative value of the voltage value is equal to or greater than a threshold value. The press acquisition unit 104 outputs the presence / absence of a press as a detection result to the state determination unit 105.

  Even if the state determination result input from the coordinate acquisition unit 102 is in the proximity state, the state determination unit 105 is in the contact state when the detection result with pressing is input from the press acquisition unit 104. Is determined. In addition, the state determination unit 105 determines that the state is the proximity state when the state determination result input from the coordinate acquisition unit 102 is in the proximity state and the detection result of no pressing is input from the press acquisition unit 104. To do. Furthermore, the state determination part 105 determines with being a contact state, when the state determination result input from the coordinate acquisition part 102 is a contact state.

  If the state determination unit 105 determines that the contact state is present, the state determination unit 105 notifies the touch coordinate processing unit 106 of the coordinates input from the coordinate acquisition unit 102. When determining that the state is the proximity state, the state determination unit 105 notifies the hover coordinate processing unit 107 of the coordinates input from the coordinate acquisition unit 102. The external object state determination method in the state determination unit 105 will be described later.

  The touch coordinate processing unit 106 executes a process associated with the touch input operation at the coordinates notified from the state determination unit 105. For example, when the keyboard is displayed on the touch panel layer 101 and the touch input operation is performed on the displayed keyboard key, the touch coordinate processing unit 106 is a number corresponding to the key on which the touch input operation has been performed. Is displayed on the touch panel layer 101.

  The hover coordinate processing unit 107 executes processing associated with the hover operation at the coordinates notified from the state determination unit 105. For example, when a map is displayed on the touch panel layer 101 and the hover operation is performed on the icon on the displayed map, the hover coordinate processing unit 107 is associated with the icon operated by the hover. Is displayed on the touch panel layer 101.

<Operation of input device>
The operation of the input device 100 according to Embodiment 1 of the present invention will be described with reference to FIG. In the description of FIG. 2, a hand is used as the conductive external object, and a gloved hand is used as the nonconductive external object.

  First, the state determination unit 105 determines whether or not a state determination result indicating a proximity state is input from the coordinate acquisition unit 102 (step ST201).

  If the state determination unit 105 determines that the state determination result indicating the proximity state is not input (step ST201: NO), the state determination unit 105 determines whether the state determination result indicating the contact state is input from the coordinate acquisition unit 102. Determination is made (step ST202).

  If the state determination unit 105 determines that the state determination result indicating the contact state has not been input (step ST202: NO), the process ends.

  On the other hand, when the state determination unit 105 determines that the state determination result indicating the contact state is input (step ST202: YES), the touch coordinate processing unit 106 performs a process associated with the touch input operation (step ST203).

  In addition, when the state determination unit 105 determines in step ST201 that the state determination result indicating the proximity state is input (step ST201: YES), whether or not the detection result indicating presence of pressure is input from the press acquisition unit 104. Is determined (step ST204).

  If hover coordinate processing section 107 determines that a detection result indicating no pressing is input in state determination section 105 (step ST204: NO), hover coordinate processing section 107 performs a process associated with a hover operation (step ST205).

  On the other hand, when the state determination unit 105 determines that the detection result with the pressing has been input (step ST204: YES), the touch coordinate processing unit 106 performs a process associated with the touch input operation (step ST206). Thereby, the input device 100 can perform processing associated with the touch input operation even when the touch input operation is performed through the glove. Note that the process associated with the touch input operation may be the same as or different from the process associated with the touch input operation in step ST203.

  The input device 100 performs the operation of FIG. 2 every time the touch panel layer 101 is scanned.

<External object state determination method>
An external object state determination method according to Embodiment 1 of the present invention will be described with reference to FIG. In FIG. 3, it is assumed that an external object that operates the touch panel layer 101 is a finger wearing a glove.

  In a state where an external object is present outside the proximity area # 300 (the states P1 and P7 in FIG. 3), the input device 100 cannot detect coordinates in the coordinate acquisition unit 102 and is in a contact state and proximity. It is determined that it is not in a state.

  When there is an external object in the proximity area # 300, the input device 100 detects the coordinates in the coordinate acquisition unit 102 and determines that the proximity state is present. When the input device 100 is not pressing the pressure sensor 103 (P2, P3, P5, and P6 in FIG. 3), the input device 100 is in the proximity state in the coordinate acquisition unit 102 and the state determination unit 105. judge. Thereby, the hover coordinate processing unit 107 performs processing associated with the hover operation.

  The input device 100 determines that the coordinate acquisition unit 102 is in the proximity state when an external object is present in the proximity area # 300 and the pressure sensor 103 is being pressed (P4 in FIG. 3). Even in such a case, the state determination unit 105 determines that the contact state is established. Thereby, the touch coordinate processing unit 106 performs processing associated with the touch input operation.

<Effect of Embodiment 1>
According to the present embodiment, the hover operation and touch input operation with a finger and the hover operation and touch input operation with a glove can all be discriminated, so that the operation intended by the user can be reliably executed.

“Embodiment 2”

The configuration of input device 400 according to Embodiment 2 of the present invention will be described with reference to FIG.

  4 includes a timer 401 and a state determination unit 402 instead of the state determination unit 105, as compared with the input device 100 according to the first embodiment illustrated in FIG. In FIG. 4, parts having the same configuration as in FIG.

  The input device 400 includes a touch panel layer 101, a coordinate acquisition unit 102, a press sensor 103, a press acquisition unit 104, a touch coordinate processing unit 106, a hover coordinate processing unit 107, a timer 401, and a state determination unit 402. And is composed mainly of.

  The coordinate acquisition unit 102 outputs the coordinate detection result and the state determination result to the state determination unit 402. Since the configuration other than the above in the coordinate acquisition unit 102 is the same as that in the first embodiment, description thereof is omitted.

  The press acquisition unit 104 outputs the presence / absence of a press to the state determination unit 402 as a detection result. In addition, since the structure except the above in the press acquisition part 104 is the same as that of the said Embodiment 1, the description is abbreviate | omitted.

  The timer 401 measures time until a predetermined time T1 elapses according to the control of the state determination unit 402. The timer 401 outputs a count-up signal to the state determination unit 402 when the predetermined time T1 has elapsed.

  Even if the state determination result input from the coordinate acquisition unit 102 is in the proximity state, the state determination unit 402 is in a contact state when a detection result with a press is input from the press acquisition unit 104. Is determined. Further, the state determination unit 402 determines that the state is the proximity state when the state determination result input from the coordinate acquisition unit 102 is in the proximity state and the detection result of no pressing is input from the press acquisition unit 104. To do. Further, the state determination unit 402 determines that the state is a contact state when the state determination result input from the coordinate acquisition unit 102 is a contact state.

  If the state determination unit 402 determines that the contact state is present, the state determination unit 402 notifies the touch coordinate processing unit 106 of the coordinates input from the coordinate acquisition unit 102. When it is determined that the state is the proximity state, the state determination unit 402 notifies the hover coordinate processing unit 107 of the coordinates input from the coordinate acquisition unit 102.

  When the state determination result input from the coordinate acquisition unit 102 is in the proximity state and when the detection result with pressing is input from the press acquisition unit 104, the state determination unit 402 performs touch input to the timer 401. Control is performed so that the time is measured until a predetermined time T1 elapses from the time when processing associated with the operation is started. The state determination unit 402 notifies the coordinates to the touch coordinate processing unit 106 until the timer 401 passes the predetermined time T1. Then, when a count-up signal indicating that the predetermined time T1 has elapsed is input from the timer 401, the state determination unit 402 stops the notification of coordinates to the touch coordinate processing unit 106, while the hover coordinate processing unit 107. Notify the coordinates. That is, the state determination unit 402 continues to notify the coordinate to the touch coordinate processing unit 106 until the predetermined time T1 has elapsed.

  The touch coordinate processing unit 106 executes processing associated with the touch input operation at the coordinates notified from the state determination unit 402. The touch coordinate processing unit 106 stops the process associated with the touch input operation when the coordinate notification stops after receiving the coordinate notification from the state determination unit 402.

  The hover coordinate processing unit 107 executes processing associated with the hover operation at the coordinates notified from the state determination unit 402.

<Operation of input device>
The operation of the input device 400 according to Embodiment 2 of the present invention will be described with reference to FIG. In the description of FIG. 5, a hand is used as the conductive external object, and a gloved hand is used as the nonconductive external object.

  First, state determination section 402 determines whether or not a state determination result in the proximity state has been input from coordinate acquisition section 102 (step ST501).

  If the state determination unit 402 determines that the state determination result indicating the proximity state is not input (step ST501: NO), the state determination unit 402 determines whether the determination result indicating the contact state is input from the coordinate acquisition unit 102. (Step ST502).

  If state determination section 402 determines that a state determination result indicating a contact state has not been input (step ST502: NO), the process ends.

  On the other hand, when it is determined by the state determination unit 402 that the state determination result indicating the contact state is input (step ST502: YES), the touch coordinate processing unit 106 performs a process associated with the touch input operation (step ST503).

  If state determination section 402 determines in step ST501 that a state determination result indicating a proximity state has been input (step ST501: YES), whether or not a detection result indicating that a press has been input is input from press acquisition section 104. Is determined (step ST504).

  If state determination section 402 determines that a detection result with a press has been input (step ST504: YES), it turns on the glove mode (step ST505). Here, the glove mode refers to a mode in which the touch panel layer 101 is processed as operated through a glove.

  State determination section 402 resets timer 401 (step ST506).

  Next, touch coordinate processing section 106 performs processing associated with the touch input operation (step ST507).

  On the other hand, if it is determined in step ST504 that no pressure is detected (step ST504: NO), state determination unit 402 determines whether the glove mode is ON (step ST508).

  When the state determination unit 402 determines that the glove mode is OFF (step ST508: NO), the hover coordinate processing unit 107 performs processing associated with the hover operation (step ST509).

  On the other hand, when it is determined that the glove mode is ON (step ST508: YES), state determination unit 402 determines whether timer 401 has already started the measurement operation (step ST510).

  If state determination section 402 determines that timer 401 has not started the measurement operation (step ST510: NO), state determination section 402 performs control to set timer 401 and start measuring predetermined time T1 (step ST511). ). Thereafter, the touch coordinate processing unit 106 performs the process of step ST507.

  On the other hand, when determining that the timer 401 has already started the measurement operation (step ST510: YES), the state determination unit 402 determines whether or not the predetermined time T1 measured by the timer 401 has expired. (Step ST512).

  If state determination unit 402 determines that predetermined time T1 has expired (step ST512: YES), it turns off the glove mode (step ST513). Thereafter, the hover coordinate processing unit 107 performs the process of step ST509.

  On the other hand, if state determination section 402 determines that predetermined time T1 has not expired (step ST512: NO), it performs the process of step ST507. Thereby, the input device 400 continues the process accompanying the touch input operation in the touch coordinate processing unit 106 while the glove mode is ON (predetermined time T1).

  The input device 400 performs the operation of FIG. 5 every time the touch panel layer 101 is scanned.

<External object state determination method>
An external object state determination method according to Embodiment 2 of the present invention will be described with reference to FIG.

  FIG. 6 shows a state in which the touch input operation is continued when the gloved hand slides on the touch panel layer 101. In the case of FIG. 6, the pressing force applied to the touch panel layer 101 from the user's hand is absorbed by the gloves. For this reason, in reality, there may be a case where a pressing force smaller than the pressing force considered necessary when the touch input operation is continued is applied. As a result, a state where the pressing force becomes small (the state of P11 in FIG. 6) may occur while the touch input operation is continued (in the middle of the slide).

  In the present embodiment, after the glove mode is turned on, the predetermined time T1 has elapsed even when the pressing force is reduced during the touch input operation and the pressing acquisition unit 104 cannot detect the pressing. Until this is done, the process associated with the touch input operation is continued.

<Effect of Embodiment 2>
According to the present embodiment, in addition to the effect of the first embodiment, after the glove mode is turned on, the process associated with the touch input operation is continued until the predetermined time T1 elapses. Even when the accompanying process is continued, even when the pressing force on the touch panel layer 101 is unintentionally reduced, the operation intended by the user can be reliably executed.

  Further, according to the present embodiment, whether or not the glove mode is switched from ON to OFF is determined based on the time measured by the timer 401, so that the slide operation can be continued by a simple method.

A configuration of input device 700 according to Embodiment 3 of the present invention will be described with reference to FIG.

  The input device 700 illustrated in FIG. 7 includes a storage unit 701, and has a coordinate acquisition unit 702 instead of the coordinate acquisition unit 102, as compared with the input device 100 according to the first embodiment illustrated in FIG. A state determination unit 703 is provided instead of the determination unit 105, and a touch coordinate processing unit 704 is provided instead of the touch coordinate processing unit 106. In FIG. 7, parts having the same configuration as in FIG.

  The input device 700 includes a touch panel layer 101, a pressure sensor 103, a press acquisition unit 104, a hover coordinate processing unit 107, a storage unit 701, a coordinate acquisition unit 702, a state determination unit 703, and a touch coordinate processing unit 704. And is composed mainly of.

  The storage unit 701 stores the intensity of the signal input from the state determination unit 703.

  The coordinate acquisition unit 702 detects coordinates touched by an external object or coordinates approached by an external object based on the intensity of a signal output from each electrode of the touch panel layer 101.

  The coordinate acquisition unit 702 determines the contact state and proximity state of the external object based on the intensity of the signal output from each electrode of the touch panel layer 101. Note that an example of a method for determining the contact state and the proximity state in the coordinate acquisition unit 702 is the same as that in the first embodiment, and thus the description thereof is omitted.

  The coordinate acquisition unit 702 outputs the coordinate detection result and the state determination result to the state determination unit 703. The coordinate acquisition unit 702 outputs a signal strength detection result to the state determination unit 703 in response to a request from the state determination unit 703.

  The press acquisition unit 104 outputs a detection result to the state determination unit 703 when a press is detected. In addition, since the structure except the above in the press acquisition part 104 is the same as that of the said Embodiment 1, the description is abbreviate | omitted.

  Even if the state determination result input from the coordinate acquisition unit 702 is in the proximity state, the state determination unit 703 is in a contact state when a detection result with a press is input from the press acquisition unit 104. Is determined. In addition, the state determination unit 703 determines that the state is the proximity state when the state determination result input from the coordinate acquisition unit 702 is the proximity state and the detection result of no pressing is input from the press acquisition unit 104. To do. Furthermore, when the state determination result input from the coordinate acquisition unit 702 is a contact state, the state determination unit 703 determines that the state is a contact state.

  If the state determination unit 703 determines that the contact state is present, the state determination unit 703 notifies the touch coordinate processing unit 704 of the coordinates input from the coordinate acquisition unit 702. When determining that the state is the proximity state, the state determination unit 703 notifies the hover coordinate processing unit 107 of the coordinates input from the coordinate acquisition unit 702.

  The state determination unit 703 performs processing in the touch coordinate processing unit 704 when the state determination result input from the coordinate acquisition unit 702 is in the proximity state and when the detection result with pressing is input from the press acquisition unit 104. The coordinate acquisition unit 702 is requested to output the detection result of the signal strength at the start. Then, the state determination unit 703 stores the detection result of the signal intensity acquired from the coordinate acquisition unit 702 in the storage unit 701 as a reference value. It should be noted that the state determination unit 703 is not the signal strength when the touch coordinate processing unit 704 starts processing, but when the touch coordinate processing unit 704 is executing processing (the press acquisition unit 104 detects a press). Until the pressure is no longer detected) may be stored in the storage unit 701. Thereby, it is possible to cope with the case where the user unintentionally weakens the pressing force.

  The state determination unit 703 determines whether or not to continue the process in the touch coordinate processing unit 704 based on the reference value stored in the storage unit 701. When the state determination unit 703 determines to stop the process in the touch coordinate processing unit 704, the state determination unit 703 notifies the touch coordinate processing unit 704 of the stop of the process. Here, the reference value is a variable value because it is stored every time the touch coordinate processing unit 704 starts processing.

  The touch coordinate processing unit 704 executes processing associated with the touch input operation at the coordinates notified from the state determination unit 703. Then, the touch coordinate processing unit 704 continues the process associated with the touch input operation until receiving a notification of the process stop from the state determination unit 703.

  The hover coordinate processing unit 107 executes a process associated with the hover operation at the coordinates notified from the state determination unit 703.

<Operation of input device>
The operation of the input device 700 according to Embodiment 3 of the present invention will be described with reference to FIG. In the description of FIG. 8, a hand is used as the conductive external object, and a gloved hand is used as the nonconductive external object.

  First, state determination section 703 determines whether or not a state determination result indicating a proximity state has been input from coordinate acquisition section 702 (step ST801).

  If the state determination unit 703 determines that the state determination result in the proximity state has not been input (step ST801: NO), the state determination unit 703 determines whether or not the state determination result in the contact state has been input from the coordinate acquisition unit 702. Determination is made (step ST802).

  If state determination section 703 determines that a state determination result indicating a contact state has not been input (step ST802: NO), the process ends.

  On the other hand, when touch state processing section 704 determines that a state determination result indicating a contact state is input in state determination section 703 (step ST802: YES), touch coordinate processing section 704 performs a process associated with the touch input operation (step ST803).

  If state determination section 703 determines in step ST801 that a state determination result indicating a proximity state has been input (step ST801: YES), whether or not a detection result indicating that a press has been input is input from press acquisition section 104. Is determined (step ST804).

  If state determination section 703 determines that a detection result with a press has been input (step ST804: YES), it turns on the glove mode (step ST805).

  Next, touch coordinate processing section 704 performs processing associated with the touch input operation (step ST806). At this time, the state determination unit 703 acquires the detection result of the signal strength from the coordinate acquisition unit 702 and stores it in the storage unit 701 as a reference value.

  On the other hand, when it is determined in step ST804 that a detection result indicating no pressing has been input (step ST804: NO), state determination section 703 determines whether or not the glove mode is ON (step ST807).

  When the state determination unit 703 determines that the glove mode is OFF (step ST807: NO), the hover coordinate processing unit 107 performs processing associated with the hover operation (step ST808).

  On the other hand, when it is determined that the glove mode is ON (step ST807: YES), state determination unit 703 reads the reference value stored in storage unit 701, and sets a threshold based on the read reference value. To do. The state determination unit 703 sets, for example, a value of 80% of the reference value as a threshold value.

  Then, state determination section 703 determines whether or not the intensity of the signal as the detection result acquired from coordinate acquisition section 702 is equal to or less than a threshold (step ST809).

  When the state determination unit 703 determines that the signal strength is greater than the threshold (step ST809: NO), the touch coordinate processing unit 704 performs the process of step ST806.

  On the other hand, when state determination section 703 determines that the signal strength is equal to or lower than the threshold value (step ST809: YES), it turns off the glove mode (step ST810). Thereafter, the hover coordinate processing unit 107 performs the process of step ST808.

  The input device 700 performs the operation of FIG. 8 every time the touch panel layer 101 is scanned.

<External object state determination method>
An external object state determination method according to Embodiment 3 of the present invention will be described with reference to FIG.

  In the middle of continuing the touch input operation, a state where the hand is lifted from the touch panel layer 101 (state P21 in FIG. 9) may occur.

  In the present embodiment, the touch coordinate processing unit 704 is a case where the pressing force is reduced while the touch input operation is continued after the glove mode is turned ON, and the pressing acquisition unit 104 cannot detect the pressing. However, as long as the intensity of the signal does not fall below the threshold value, the process associated with the touch input operation is continued.

<Effect of Embodiment 3>
According to the present embodiment, in addition to the effect of the first embodiment, after the glove mode is turned on, the process associated with the touch input operation is continued unless the signal strength falls below the threshold value. Even if the pressing force applied to the touch panel layer 101 is unintentionally reduced during the processing associated with the operation, the operation intended by the user can be reliably executed.

  In addition, according to the present embodiment, the signal intensity when the glove mode is turned on is updated every time the glove mode is turned on to be the reference value, so the threshold value to be compared with the signal intensity is optimal. Can be set to any value.

  Further, according to the present embodiment, after the glove mode is turned on, when the signal strength is equal to or lower than the threshold value, the glove mode is turned off and the process associated with the hover operation is executed. The external object release determination can be made to accurately follow the timing at which the external object is actually released from the touch panel layer 101.

  In the present embodiment, the reference value is a variable value, but may be a fixed value.

  In the first to third embodiments, the touch panel layer 101 is operated with a bare hand and a glove. However, the touch panel layer 101 is formed with a conductive external object other than a bare hand and a non-conductive external object other than a glove. You may operate. In this case, the same effect can be obtained.

  Further, although cases have been described with the above Embodiments 1 to 3 as examples where they are configured by hardware, the present invention can also be realized by software.

FIG. 10 is a block diagram illustrating a schematic configuration of an electronic device 1001 according to an embodiment of the present invention. FIG. 11 is a perspective view showing an external appearance of the electronic apparatus of FIG. An electronic device 1001 according to this embodiment is one in which the present invention is applied to, for example, a portable wireless device called a smartphone. Note that in the block diagram of FIG. 10, a portion that functions as a wireless device is omitted.

  In FIG. 10, an electronic device 1001 according to this embodiment includes a touch panel layer 1002, a pressure sensor (corresponding to a pressure detection unit) 1003, a display unit 1004, a storage unit 1007, and a control unit 1008. Also, as shown in FIG. 11, electronic device 1001 according to the present embodiment has a vertically-long rectangular casing 1110. That is, when the electronic device 1001 is viewed from above, the housing 1110 looks like a vertically long rectangle.

  A touch panel layer 1002, a press sensor 1003, and a home key 1111 are arranged on the front surface 1110 A side of the housing 1110. The touch panel layer 1002 is disposed so as to overlap the pressure sensor 1003 so as to be on the front side of the pressure sensor 1003.

  The home key 1111 is disposed directly below the touch panel layer 1002 and the pressure sensor 1003 on the front side of the housing 1110. That is, the home key 1111 is disposed on the front side of the housing 1110 and at a position away from the touch panel layer 1002 and the pressure sensor 1003 along the long side direction of the vertically long rectangle of the housing 1110.

  Although not shown in FIG. 11, protective glass (corresponding to a transparent member) is disposed on the front surface side of the touch panel layer 1002, and a display unit 1004 is provided on the inner side of the housing 1110 than the press sensor 1003. Has been placed. That is, the touch panel layer 1002 is disposed between the protective glass and the display portion 1004.

  FIG. 12 is a diagram showing the arrangement of the protective glass 1212, the pressure sensor 1003, and the display unit 1004. As shown in the figure, the display unit 1004 and the pressure sensor 1003 are arranged in this order under the glass 1212. The glass 1212 has a planar shape and has a predetermined transmittance for visible light and transmits the display of the display portion 1004. Further, at least a part of the glass 1212 is disposed so as to be exposed from the casing 1110, and the other part is disposed inside the casing 1110. Note that the touch panel layer 1002 is disposed in contact with the lower surface of the glass 1212.

  The touch panel layer 1002 and the display unit 1004 are formed in a planar shape having an area slightly smaller than the area of the front surface 1110A of the housing 1110 and a vertically long rectangular shape in plan view. In this case, the area of the display unit 1004 is slightly smaller than the area of the touch panel layer 1002.

  The touch panel layer 1002 has an indicator (a finger skin portion, a dedicated pen, etc.) having predetermined conductivity on the panel surface, and is mainly handled as a “finger” in this embodiment. ) Employs a capacitance method that enables operation within a predetermined range of height without touching (referred to as “hover operation”).

  As shown in FIG. 30, the touch panel layer 1002 adopting the electrostatic capacitance method includes a transmission electrode 3001 and a reception electrode 3002, which are arranged apart from each other on the lower surface of a plate-like dielectric 3000 (glass or the like). Is done. A driving pulse based on a transmission signal is applied to the transmission electrode 3001. When a drive pulse is applied to the transmission electrode 3001, an electric field is generated from the transmission electrode 3001, and when a finger enters the electric field, the number of lines of electric force between the transmission electrode 3001 and the reception electrode 3002 decreases. The change in the number appears as a change in the charge at the receiving electrode 3002.

  The touch panel layer 1002 detects a finger from a received signal corresponding to a change in charge at the receiving electrode 3002, detects coordinates (x, y) along the surface of the display unit 1004 of the finger, and a vertical distance ( z) is detected, and the detected two-dimensional coordinates (x, y) and vertical distance (z) are output to the control unit 1008.

  Returning to FIG. 12, the pressure sensor 1003 detects a pressure on the glass 1212 by a finger or the like by detecting at least a distortion of the protective glass 1212. The display unit 1004 has a rectangular shape and is used for display for operating the electronic device 1001, display of images, and the like. The display unit 1004 includes an LCD (Liquid Crystal Display) and a backlight, and is disposed on the back side of the touch panel layer 1002 with the LCD side facing the touch panel layer 1002 side.

  The display unit 1004 includes an LCD, but may include a display device such as an organic EL (Electro Luminescence) or electronic paper in addition to the LCD.

  Returning to FIG. 10, the storage unit 1007 has a volatile memory such as a DRAM (Dynamic Random Access Memory), and stores the settings when the user performs settings for using the electronic device 1001. The control unit 1008 controls each unit of the electronic device 1001 and includes a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and an interface circuit. The ROM stores a program for controlling the CPU, and the RAM is used in the operation of the CPU.

  Here, the positional relationship between the touch panel layer 1002 and a finger that is a pointer (if it has predetermined conductivity, for example, a part of the skin or a dedicated pen) may be described. . FIG. 13 is a diagram showing a positional relationship between the touch panel layer 1002 and a finger 1370 that is an indicator. As shown in the drawing, when the vertical distance (z) with the finger 1370 is equal to or smaller than the first value in the sky of the touch panel layer 1002, the touch state is established. Further, when the vertical distance (z) with the finger 1370 is equal to or smaller than the second value which is greater than the first value, the hover state is established.

  The control unit 1008 sets the two-dimensional coordinates (x, y) as effective coordinates in the following cases (1) to (3).

  (1) When the vertical distance (z) output from the touch panel layer 1002 is equal to or smaller than the first value (that is, in the touch state), at least two-dimensional coordinates (x, y) output from the touch panel layer 1002 Use valid coordinates.

  (2) When the vertical distance (z) output from the touch panel layer 1002 is equal to or smaller than the first value (that is, in the touch state) and the pressure sensor 1003 detects a predetermined strain, at least the touch panel layer The two-dimensional coordinates (x, y) output from 1002 are set as effective coordinates.

  (3) When the vertical distance (z) output from the touch panel layer 1002 is greater than the first value and less than or equal to the second value (that is, in the hover state), and the pressure sensor 1003 has a predetermined distortion Is detected, at least two-dimensional coordinates (x, y) output from the touch panel layer 1002 are set as effective coordinates.

  FIG. 14 is a diagram illustrating determination of the touch panel layer 1002 and the pressure sensor 1003, and the control unit 1008 in each detection state. In the figure, ◯ indicates detection and × indicates non-detection.

  The detection state A is a state in which the touch panel layer 1002 detects a touch and the pressure sensor 1003 does not detect the distortion of the glass 1212. In this state, the control unit 1008 can detect a finger (feather touch).

  The detection state B is a state where the touch panel layer 1002 detects a touch and the pressure sensor 1003 detects distortion of the glass 1212. In this state, the control unit 1008 can detect a finger (pressing).

  The detection state C is a state in which the touch panel layer 1002 only detects the hover. In this state, the control unit 1008 determines that the hover.

  The detection state D is a state in which the touch panel layer 1002 detects hover and the pressure sensor 1003 detects distortion of the glass 1212. In this state, the control unit 1008 can detect gloves or nails.

Returning to FIG. 10, the display unit 1004 performs display corresponding to effective two-dimensional coordinates (x, y). For example, a pointer or icon is displayed. FIG. 15 is a diagram illustrating an example of displaying icons. As shown in (a) of the figure, when the two-dimensional coordinates (x ₁ , y ₁ ) are valid coordinates, an icon 1530 is displayed as shown in (b) of the figure. A pointer (not shown) may be displayed corresponding to the effective coordinates (x, y). When the pointer overlaps with the icon, the icon is made selectable, and when the finger 1370 approaches the touch panel layer 1002 below the first vertical distance in this state, the icon is displayed. It is also possible to activate the corresponding function. The control unit 1008 displays the pointer or icon and activates the function corresponding to the icon.

  Note that the first value of the vertical distance may be 0 (zero).

  Next, the operation of electronic device 1001 according to this embodiment will be described.

  FIG. 16 is a diagram illustrating a detection state of the finger 1370 when the finger 1370 is gradually brought closer to the touch panel layer 1002, touched the touch panel layer 1002, and then gradually separated from the touch panel layer 1002.

  In the figure, when the vertical distance (z) between the finger 1370 and the touch panel layer 1002 exceeds a threshold value (second value), the detection state of the touch panel layer 1002 is “non-detection”. Thereafter, when the vertical distance (z) is equal to or smaller than the threshold value (second value), the detection state of the touch panel layer 1002 becomes “hover detection”. Thereafter, when the finger 1370 comes close enough to touch the surface of the touch panel layer 1002 (actually, the surface of the glass 1212), the detection state of the touch panel layer 1002 becomes “touch detection”. At this time, the control unit 1008 determines that the touch has occurred. Thereafter, when the finger 1370 moves away from the surface of the touch panel layer 1002, the detection state of the touch panel layer 1002 becomes “hover detection”. This state of hover detection continues until the vertical distance (z) between the finger 1370 and the touch panel layer 1002 exceeds a threshold value (second value), and when the threshold value (second value) is exceeded, “not detected”. It becomes.

  FIG. 17 is a diagram illustrating a detection state of the glove 1780 when a finger 1370 with a glove 1780 is gradually brought closer to the touch panel layer 1002, touched the touch panel layer 1002, and then gradually separated from the touch panel layer 1002. It is.

  In the figure, when the vertical distance (z) between the finger 1370 and the touch panel layer 1002 exceeds a threshold value (second value), the detection state of the touch panel layer 1002 is “non-detection”. Thereafter, when the vertical distance (z) is equal to or smaller than the threshold value (second value), the detection state of the touch panel layer 1002 becomes “hover detection”. The state where the hover is detected continues even when the glove 1780 touches the surface of the touch panel layer 1002. This hover detection state continues until the vertical distance (z) between the finger 1370 and the touch panel layer 1002 exceeds the threshold (second value), and exceeds the threshold (second value). Not detected ”.

  On the other hand, from when the vertical distance (z) of the finger 1370 to the touch panel layer 1002 exceeds the threshold value (second value) until the glove 1780 contacts the touch panel layer 1002, the detection state of the pressure sensor 1003 is “non- Detection ". Thereafter, when the glove 1780 touches the surface of the touch panel layer 1002, the detection state of the pressure sensor 1003 becomes “detection”. Thereafter, when the glove 1780 is separated from the surface of the touch panel layer 1002, the detection state of the pressure sensor 1003 becomes “non-detection”.

  FIG. 18 is a diagram illustrating a detection state of the nail 1871 when the nail 1871 is gradually brought closer to the touch panel layer 1002, touched the touch panel layer 1002, and then gradually separated from the touch panel layer 1002.

  In the figure, when the vertical distance (z) between the finger 1370 and the touch panel layer 1002 exceeds a threshold value (second value), the detection state of the touch panel layer 1002 is “non-detection”. When the vertical distance (z) is equal to or smaller than the threshold value (second value), the detection state of the touch panel layer 1002 becomes “hover detection”. The state where the hover is detected continues even when the nail 1871 touches the surface of the touch panel layer 1002. This hover detection state continues until the vertical distance (z) between the finger 1370 and the touch panel layer 1002 exceeds a threshold value (second value). Detection ".

  On the other hand, from when the vertical distance (z) of the finger 1370 to the touch panel layer 1002 exceeds the threshold value (second value) until the nail 1871 contacts the touch panel layer 1002, the detection state of the pressure sensor 1003 is “non- Detection ". When the nail 1871 touches the surface of the touch panel layer 1002, the detection state of the pressure sensor 1003 becomes “detection”. When the nail 1871 moves away from the surface of the touch panel layer 1002, the detection state of the pressure sensor 1003 becomes “non-detection”.

  Next, FIG. 19 is a flowchart showing the indicator discriminating process of electronic device 1001 according to this embodiment. In the figure, the control unit 1008 acquires the detection state by taking in the outputs of the touch panel layer 1002 and the pressure sensor 1003 (step S1901). When the control unit 1008 acquires the detection state, the control unit 1008 determines whether the state is touch detection (step S1902), and determines that the detection is touch detection (that is, determines “YES” in the determination of step S1902). It is determined whether or not the state is pressure detection (step S1908).

  If it is determined in step S1908 that the pressure is not detected (ie, if “NO” is determined in step S1908), it is determined that the finger 1370 is touched (feather touch), and two-dimensional coordinates (x, y) are determined. Are effective coordinates (step S1909). Thereafter, the process returns to step S1901.

  If it is determined in step S1908 that the pressure is detected (ie, if “YES” is determined in step S1908), it is determined that the finger 1370 is touched (pressed), and two-dimensional coordinates (x, y) are determined. Are effective coordinates (step S1903). Thereafter, the process returns to step S1901.

  If it is determined in step S1902 that it is not touch detection (that is, if “NO” is determined in step S1902), it is determined whether hover detection is detected (step S1904), and if it is not hover detection (that is, If “NO” is determined in the determination in step S1904), the process returns to step S1901. On the other hand, when it is determined that hover detection is performed (that is, when “YES” is determined in the determination in step S1904), it is determined whether or not it is pressure detection (step S1905). In this determination, when it is determined that the pressure is detected (that is, when “YES” is determined in the determination in step S1905), it is determined that the touch is performed by the glove 1780 or the nail 1871, and the two-dimensional coordinates (x, y) are determined. Valid coordinates are set (step S1906). After determining that the touch is with the glove 1780 or the nail 1871, the process returns to step S1901.

  If it is determined in step S1905 that pressure is not detected (that is, if “NO” is determined in step S1905), it is determined that the object is a simple hover (step S1907). Thereafter, the process returns to step S1901. In step S1907, the two-dimensional coordinates (x, y) may or may not be effective coordinates.

  Thus, according to electronic device 1001 according to the present embodiment, touch panel layer 1002 and pressure sensor 1003 are provided, and when a touch is detected by touch panel layer 1002, it is determined that the touch is made with a finger, and touch panel layer 1002 at that time is determined. When the hover is detected by the touch panel layer 1002 and the press sensor 1003 detects a predetermined distortion, it is determined that the touch is a gloved touch or a nail touch. Since the two-dimensional coordinates output from the touch panel layer 1002 at that time are effective coordinates, the touch panel can be touched with a fingernail, touched with a glove, or touched with a long nail. It is possible to detect where the button is pressed.

  That is, when a predetermined strain is detected by the pressure sensor 1003 even when the protective glass 1212 is touched with a long nail tip or a fingertip wearing a glove or the like, that is, when the vertical distance is larger than the first value. Since the dimensional coordinate is an effective coordinate, the two-dimensional coordinate can be input even at the tip of the toe or the fingertip of the glove.

  Note that in the electronic device 1001 according to this embodiment, the square pressure sensor 1003 that is slightly larger than the display unit 1004 is disposed below the display unit 1004. However, the present invention is not limited to this. For example, FIG. As shown in the figure, a belt-like press sensor 1003A may be arranged along one of the short sides of the display unit 1004. As shown in the figure, a home key 1111 is provided on the short side of the rectangle of the display unit 1004, and the press sensor 1003A is disposed along the short side. Accordingly, the space can be effectively used by arranging the press sensor 1003A using the space around the home key 1111.

  In addition, as shown in FIG. 21, four band-shaped press sensors 1003A may be used and arranged along each of the four sides of the display unit 1004, or arranged along any one side, It may be arranged along any two sides, or may be arranged along any three sides. In this case, since the display unit 1004 has a rectangular shape, it goes without saying that the pressure sensor 1003A disposed along both long sides of the display unit 1004 is longer than the pressure sensor 1003A disposed along both short sides. By using the belt-shaped press sensor 1003A and placing it close to the display unit 1004, the space can be used effectively.

  Further, in electronic device 1001 according to this embodiment, as shown in the flowchart of FIG. 19, it is possible to determine touch with a finger (feather touch) / touch with finger (push-in) / touch with glove or nail / hover. However, the display on the display unit 1004 may be switched according to these determination results.
