Description

  The present invention relates to a terminal device and a control method for the terminal device. In particular, the present invention relates to a terminal device including a plurality of touch panels and a control method thereof.

  In recent years, a touch panel has been used as an input device of a terminal device, and a user can perform an input operation by pressing or touching the surface of the touch panel with a finger or a pen.

  Furthermore, in order to enable operation with a wide range of input means, a terminal device having a plurality of types of touch panels has been proposed.

  For example, Patent Document 1 discloses a configuration in which a resistive touch panel and a capacitive touch panel are arranged in an overlapping manner. When this touch panel is operated with a bare hand, it can be detected by both methods, whereas when it is operated with a finger sucker, it can be detected only by a resistive film method. Due to such a difference in detection results, it is possible to detect two types of pressing states with bare hands and finger sack.

  Also, Patent Document 2 discloses a configuration in which a resistive touch panel and a capacitive touch panel are stacked. In this touch panel, the resistive touch panel is in a standby state in which input detection is not performed until there is contact or proximity on the capacitive touch panel, and input is performed by contact or proximity to the capacitive touch panel. The operation state is shifted to the detection state. Thereby, a touch panel with reduced power consumption can be provided.

[First Embodiment]
(Configuration of the first embodiment)
The first embodiment will be described in detail with reference to the drawings. FIG. 3 is a block diagram illustrating a schematic configuration of the terminal device 1 according to the first embodiment. In FIG. 3, the terminal device 1 is a smartphone-type terminal device 1 in which a touch panel unit 10 and a display unit 13 are arranged so that a user performs an input operation on the touch panel unit 10 while viewing a screen displayed on the display unit 13. is there. In FIG. 2, the touch panel unit 10 and the display unit 13 are controlled by the touch panel control unit 9 and the display control unit 8, respectively. The terminal device 1 further includes a transmission / reception unit 4, a storage unit 3, an audio processing unit 5, a microphone 6, a speaker 7, and a control unit 2, thereby fulfilling a function as a normal mobile phone. The control unit 2 has a CPU (Central Processing Unit) (not shown), and appropriately controls the entire terminal device 1 by calling programs and data stored in the storage unit 3.

  Next, FIG. 5 is a diagram schematically illustrating the configuration of the touch panel unit 10 and the display unit 13. The terminal device 1 according to the first embodiment includes two different types of touch panels that are arranged on top of each other. Specifically, as illustrated in FIG. 5, the terminal device 1 includes a capacitive touch panel 11 (first touch panel) and a resistive film touch panel 12 (second touch panel), and the display unit 13. Are arranged in the order of the display unit 13, the resistive touch panel 12, and the capacitive touch panel 11. Therefore, the input operation surface 15 on which the user performs an input operation is the upper surface of the capacitive touch panel 11. A similar configuration is disclosed in, for example, Patent Document 1 (FIG. 3 of Patent Document 1).

  The capacitive touch panel (first touch panel) 11 outputs the contact of a conductive contact object and its contact point. On the other hand, the resistance film type touch panel (second touch panel) 12 outputs the contact by the substance and the contact point regardless of the presence or absence of the conductivity of the contact object. In the first embodiment, by using two touch panels having different detection characteristics in this way, the contact object used for the input operation is a conductive contact object and a non-conductive contact object. Which one is being determined.

  Next, FIG. 6 shows an example of a contact object when an operation is input on the touch panel unit 10. FIG. 6A shows a finger 91 as an example of a conductive contact object. FIG. 6B shows a pen 92 as an example of a non-conductive contact object. The pen 92 is a so-called “stylus pen” and is the same as that widely used in PDA (Personal Data Assistants), game machines, tablet terminals, and the like. However, the conductive contact object and the non-conductive contact object are not limited to the examples shown in FIGS. That is, any conductive substance as a conductive contact object and any non-conductive substance as a non-conductive contact object can be applied. For example, a stylus pen whose tip is made of metal can be used as the conductive contact object. In addition, as a non-conductive contact object, a finger wearing a finger sack, a finger wearing a glove, or the like is applicable.

  Next, FIG. 7 shows an example of an unlock screen by the touch panel unit 10 of the terminal device 1. FIG. 7A shows a lock release screen in which a password is entered in the password input area 93 and a predetermined usage restriction is released when the password matches a preset password. The password is one or more characters, one or more numbers, or a combination of one or more characters and one or more numbers, and is set in advance by the user.

  Next, FIG. 7B shows a lock release screen. In the pattern input area 94, the pattern is traced in order, and the usage restriction is released when the traced path matches a preset path. Is. In the present specification, the term “password” hereinafter includes those entered by the method of FIG. 7B.

  Next, the password input in the first embodiment and the use restriction cancellation by the password will be described in detail with reference to FIG. FIG. 2 is a block diagram illustrating a configuration of a portion related to the use restriction cancellation in the terminal device 1 according to the first embodiment. As shown in FIG. 2, the locations related to the usage restriction cancellation in the terminal device 1 are the touch panel unit 10, the first detection unit 21, the second detection unit 22, the contact object determination unit 14, and the usage. The restriction release unit 16 is included. The first detection unit 21 and the second detection unit 22 in FIG. 2 are included in the touch panel control unit 9 in FIG. 3. Moreover, the contact target determination unit 14 and the use restriction release unit 16 in FIG. 2 are programs executed by the CPU of the control unit 2 in FIG. However, the present invention is not limited to this, and part or all of the contact object determination unit 14 and the use restriction release unit 16 may be configured by hardware.

  Each part of FIG. 2 will be described in detail. In the touch panel unit 10, the password is input by the finger 91 or the pen 92 in a state where the unlock screen of FIG. 7 is displayed. The output of the capacitive touch panel (first touch panel) 11 and the output of the resistive touch panel (second touch panel) 12 are supplied to the first detection unit 21 and the second detection unit 22, respectively. Specifically, a signal indicating that the button is pressed and the pressed coordinates are transmitted from the first and second touch panels 11 and 12 to the first and second detection units 21 and 22, respectively. Here, the signal indicating that the button has been pressed is a low-level signal when the button is not pressed, and a pulse signal that transitions to the high level when the button is pressed.

  Next, the first detection unit 21 converts the pressed coordinates transmitted from the first touch panel 11 into corresponding character codes (including numbers and symbols). Then, as the first detection result C <b> 1, a signal indicating that the button has been pressed and a corresponding character code are supplied to the contact object determination unit 14 and the use restriction release unit 16.

  Similarly, the second detection unit 22 converts the pressed coordinates transmitted from the second touch panel 12 into corresponding character codes (including numbers and symbols). Then, as the second detection result C <b> 2, a signal indicating that the button has been pressed and a corresponding character code are supplied to the contact object determination unit 14 and the use restriction release unit 16.

  Next, the usage restriction canceling unit 16 inputs the first detection result C1 and the second detection result C2. The usage restriction release unit 16 determines whether or not the character code of the password included in the first detection result C1 or the second detection result C2 matches the preset same password C0. If it does not match the password C0, authentication is not established.

  On the other hand, if it matches the password C0, the contact object determination unit 14 determines whether or not there is a difference between the first detection result C1 and the second detection result C2. Specifically, first, a signal indicating that the button is pressed included in the first detection result C1 and a signal indicating that the button is pressed included in the second detection result C2 are set to the High level in common. It is determined whether or not. When the high level is common, it is determined that there is no difference between the first detection result C1 and the second detection result C2. In other cases, it is determined that there is a difference between the first detection result C1 and the second detection result C2.

  When the password is pressed with a finger (conductive contact object) 91, both the first touch panel 11 and the second touch panel 12 are detected, and a signal indicating that the password has been pressed is in common. Therefore, the contact object determination unit 14 determines that there is no difference between the first detection result C1 and the second detection result C2, and determines that the conductive contact object 91 is used. On the other hand, when the password is pressed with a pen (non-conductive contact object) 92, it is not detected by the first touch panel 11 but detected by the second touch panel 12. As a result, since the signal indicating that the button has been pressed does not become the High level in common, the contact object determining unit 14 determines that there is a difference between the first detection result C1 and the second detection result C2, and the non- It is determined that the conductive contact object 92 has been used.

  Next, the use restriction release unit 16 inputs a signal C3 indicating “conductivity / non-conductivity of the used contact object” output from the contact object determination unit 14. Then, a signal C4 for instructing the first usage restriction cancellation is output on the condition that the conductive contact object 91 has been used by the signal C3 as a condition for establishment of the authentication. Further, a signal C4 for instructing the second usage restriction cancellation is output based on the signal C3 that the non-conductive contact object 92 is used as a condition for the establishment of the authentication.

  The signal C4 for instructing the first / second usage restriction cancellation is transmitted to the control unit 2 in FIG. 3, and the control unit 2 is configured based on the preset contents of the first / second usage restriction cancellation. Cancel usage restrictions. As the first use restriction release, for example, the use restriction of the browsing function is set. In addition, as the second usage restriction release, for example, release of browsing restriction of stored data is set. However, the present invention is not limited to these, and arbitrary settings can be made as the first / second use restriction cancellation.

  Next, the operation of the first embodiment will be described in detail with reference to FIG. FIG. 4 is a flowchart showing the operation of canceling the use restriction in the terminal device 1 according to the first embodiment of the present invention. Assume that “1234” is set in advance as the password C0. In addition, as described above, as the contents of the first / second usage restriction cancellation, as described above, cancellation of browsing function usage restrictions and cancellation of stored data browsing restrictions are set.

  7A is displayed on the display unit 13 with the above settings made, and the user presses the password “1234” with the finger 91 in the password input area 93 on the touch panel unit 10. (S1). In this case, the first detection result C1 and the second detection result C2 match, and both include a character code of the password “1234”.

  Next, the usage restriction canceling unit 16 determines whether or not the input password “1234” matches the preset password C0 (S2). In step S2, it is determined that the passwords match (Yes in S2), and then it is determined whether there is a difference between the first detection result C1 and the second detection result C2 (S3). As described above, when the finger 91 is pressed, the first detection result C1 and the second detection result C2 match, so that the contact object determination unit 14 determines that there is no difference in step S3 (S2 Therefore, it is determined that the conductive contact object 91 has been used (S4).

  Then, the use restriction release unit 16 obtains information that the passwords match and that the conductive contact object 91 has been used from the contact object determination unit 14, and a signal for instructing the first use restriction release. C4 is output (S6). The control unit 2 releases the use restriction of the browsing function by the signal C4. Thus, when the user starts an application having a browsing function, the control unit 2 issues a signal for permitting execution to the application, and the browsing function is executed.

  Next, it is assumed that the user presses the password “1234” with the pen 92 in the password input area 93 on the touch panel unit 10 on the unlock screen of FIG. 7A (S1). In this case, the first detection result C1 and the second detection result C2 do not match, and only the second detection result C2 includes the character code of the password “1234”.

  Next, the usage restriction canceling unit 16 determines whether or not the input password “1234” matches the preset password C0 (S2). In step S2, it is determined that the passwords match (Yes in S2), and then it is determined whether there is a difference between the first detection result C1 and the second detection result C2 (S3). As described above, when pressed with the pen 92, the first detection result C1 and the second detection result C2 do not coincide with each other, and therefore the contact object determination unit 14 determines that there is a difference in step S3 ( In S2, it is determined as Yes), and it is determined that the non-conductive contact object 92 is used (S5).

  Then, the use restriction releasing unit 16 obtains information that the passwords match and the non-conductive contact object 92 has been used from the contact object determining unit 14, and instructs the second use restriction release. The signal C4 is output (S7). The control unit 2 releases the browsing restriction on the stored data by the signal C4. That is, the access right for the user to access the predetermined stored data is given from the control unit 2, and the user can browse the predetermined stored data.

  As described above, according to the terminal device 1 according to the first embodiment, in the terminal device including two different types of touch panels, the conductivity / non-conductivity of the contact object of the input operation is determined. Thus, it is possible to provide a terminal device capable of changing two security levels according to the determined conductivity / non-conductivity of the contact object. For example, the first usage restriction cancellation which is canceled by inputting the password with the finger 91 releases only the function having a low security level, and the second usage restriction cancellation which is canceled by inputting the password with the pen 92. By setting so as to cancel a function with a high security level, it becomes possible to set / release different security levels with the same password.

  Conventionally, when two security levels are to be set, it is necessary to set different passwords for each security level. Therefore, the user must remember two passwords, but the password that is not usually used is easy to forget, and even if there is a function with high security, it is rarely used, and as a result, high security is maintained. There is a problem that it is difficult. On the other hand, in the first embodiment, since the same password is sufficient, the above-mentioned problem of forgetting the password does not occur.

  On the touch screen unlock screen, if the user frequently inputs the same password, a trace remains on the surface of the touch panel, and the password can be easily guessed, which makes it difficult to ensure security. However, according to the terminal device 1 according to the first embodiment, even if a password is guessed by a malicious third party, the password is entered with the finger 91, and the password is entered with the pen 92. There is a possibility that it will not be done until it is entered, and access to highly confidential data such as business documents is set to require the password entry of the pen 92 to ensure security. be able to. On the other hand, regarding access to data with high urgency, such as NFC (Near Field Communication) cancellation, or data access with low confidentiality, if the use restriction is canceled by inputting the password of the finger 91, the user can Is convenient because it is easily accessible.

  In the first embodiment, the case where the first use restriction release and the second use restriction release are performed according to the conductivity / non-conductivity of the contact object used for password input has been described. However, at least one of the first / second usage restriction cancellations may not perform the usage restriction cancellation. For example, when the password is input with the finger 91, the use restriction may not be released, and only when the password is input with the pen 92, the use restriction may be released.

  In addition, at least one of the first / second usage restriction cancellations may be performed to release all usage restrictions. For example, when the password is input with the pen 92, it may be set so that all use restrictions are released.

(Modification 1 of the first embodiment)
Next, a first modification of the first embodiment will be described with reference to FIG. FIG. 8 is a block diagram illustrating a configuration of a portion related to the use restriction cancellation in the terminal device according to the first modification of the first embodiment. As can be seen by comparing FIG. 8 with FIG. 2 (first embodiment), in FIG. 8, the use restriction release unit 31 is configured to replace the first / second use restriction release C4 (FIG. 2) with the first. / The second period usage restriction cancellation C9 signal is output.

  The usage restriction release unit (16 in FIG. 2) of the first embodiment switches the content for releasing the usage restriction between the first usage restriction release and the second usage restriction release. On the other hand, in the first modification of the first embodiment, the period for canceling the usage restriction is switched between the first period and the second period. Specifically, when it is determined by the contact object determination unit 14 that the conductive contact object 91 is used, the use restriction is canceled only during the first period, and the contact object determination unit 14 performs non-conduction. When it is determined that the sex contact object 92 has been used, the use restriction is released only for the second period.

  According to the first modification of the first embodiment, for example, the second period is set longer than the first period. Accordingly, when a password is input with the finger 91, only a short period (first period) is allowed, and even if a password is guessed by a third party and the password is input with the finger 91, a short period Since it can only be used, security can be ensured. On the other hand, for short-term usage such as NFC (Near Field Communication) settlement and confirmation of incoming emails, the user immediately enters the usage restriction state after canceling the usage restriction in the first period. Can be returned. On the other hand, although the password input with the pen 92 is canceled for a long time, as described above, there is a high possibility that it will not be performed by a third party, and security can be ensured.

  Further, in the first modification of the first embodiment, the power consumption can be reduced by limiting the period of canceling the use restriction compared to the first embodiment. It should be noted that while a certain function is being executed, the execution may be permitted until the execution of the function ends even if the usage restriction release period has passed.

(Modification 2 of the first embodiment)
Next, Modification 2 of the first embodiment will be described with reference to FIG. FIG. 9 is a block diagram illustrating a configuration of a location related to the use restriction cancellation in the terminal device according to the second modification of the first embodiment. As can be seen by comparing FIG. 9 with FIG. 2 (first embodiment), in FIG. 9, the use restriction release unit 32 includes the first / second use restriction release C4 in addition to the first / second use restriction release C4. The function activation C6 signal is output.

  As shown in FIG. 9, the first function is activated in conjunction with the first usage restriction release, and the second function is activated in conjunction with the second usage restriction release. The first and second functions are set in advance by the user. For example, the first function can be registered as an e-mail application, and the second function can be registered as a notepad application for handwriting input with the pen 92.

  According to the second modification of the first embodiment, it is possible to cancel different usage restrictions and change the registered function immediately by simply changing the contact object when inputting the password. It is done.

(Modification 3 of the first embodiment)
Next, a third modification of the first embodiment will be described with reference to FIG. FIG. 10 is a block diagram illustrating a configuration of a portion related to the use restriction cancellation in the terminal device according to the third modification of the first embodiment. As can be seen by comparing FIG. 10 with FIG. 2 (first embodiment), in FIG. 10, the usage restriction canceling unit 33 outputs a signal of “partial function of predetermined application / second usage restriction releasing” C 7. Output.

  That is, in the usage restriction release unit 33 of the third modification of the first embodiment, the password is input with the finger (conductive contact object) 91, and the usage restriction is released when it matches the password C0. Instead, a predetermined operation set in advance is temporarily executed.

  The predetermined operation may be a partial function of a predetermined application as shown in FIG. As a partial function of the predetermined application, for example, a function of displaying an outline of the received content of an electronic mail may be used. Specifically, when the password is input with the finger 91 and matches the password C0, a signal C7 for starting a partial function of a predetermined application is transmitted to the control unit 2, and the control unit 2 sends the e-mail application. On the other hand, an operation for displaying a part of the contents of the e-mail such as “sender, subject, first three lines” is executed.

  According to the third modification of the first embodiment, in the case of inputting a password with a finger (conductive contact object) 91, confirmation of information is performed by a predetermined partial function without canceling the use restriction ( For example, only the above-described display of the outline of the electronic mail or the like) is performed, thereby ensuring both high security and information confirmation by simple operation.

(Modification 4 of the first embodiment)
Next, Modification 4 of the first embodiment will be described with reference to FIG. FIG. 11 is a block diagram illustrating a configuration of a location related to the use restriction cancellation in the terminal device according to the fourth modification of the first embodiment. In FIG. 11, it is assumed that an operation input is made with a pen (non-conductive contact object) 92 on the touch panel unit 10 in a state where authentication with a password is not performed. In this case, in the fourth modification of the first embodiment, a predetermined operation set in advance is executed. For example, as shown in FIG. 11, when there is an operation input made with the pen 92, the contact object determination unit 14 inputs an operation input with the pen (non-conductive contact object) 92 to the application activation unit 34. It is notified by signal C3. In response to the signal C3, the application activation unit 34 transmits a signal for activating a preset application (such as notepad or e-mail) to the control unit 2, and the control unit 2 activates the application. Furthermore, the operation input on the touch panel unit 10 is also supplied as handwritten input for the application.

  When the activated application is Notepad, the supplied handwritten input data is converted into text data and stored. When the activated application is an e-mail, the supplied handwritten input is converted into text data, and the e-mail is transmitted to a predetermined transmission destination using the converted text data.

  When the operation input on the touch panel unit 10 is input by handwriting and used, the first and second detection units 21 and 22 do not output the character code but the first and second touch panels 11. , 12 are supplied as they are.

  According to the modification 4 of 1st Embodiment, even if it is a case where the cancellation | release of the use restriction by a password is not performed, it is high by operating the touch panel part 10 with the pen (nonelectroconductive contact object) 92. The operation intended by the user can be executed while maintaining security. In particular, when the operation input of the touch panel unit 10 using the pen 92 is used as handwritten input of a preset application, it is possible to use frequently used functions of e-mail and memo pad while maintaining high security.

(Modification 5 of the first embodiment)
Next, Modification 5 of the first embodiment will be described with reference to FIG. FIG. 12 is a block diagram illustrating a configuration of a location related to the use restriction cancellation in the terminal device according to the fifth modification of the first embodiment. In the fourth modification of the first embodiment, a predetermined application is activated by an operation input with the pen 92 in a state where the use restriction by the password is not released, but the fifth modification of the first embodiment In the state where the use restriction by the password has not been lifted, by performing gesture input with the pen 92 on the touch panel unit 10, a plurality of applications are selected and activated.

  As shown in FIG. 12, the gesture input determination unit 35 uses the coordinate data output from the first and second touch panels 11 and 12 as in the fourth modification of the first embodiment, so that the user can use the pen 92. The gesture to be input is determined. In the application registration unit 55, applications or functions that are activated in response to a plurality of gestures are registered in advance. When the signal C3 is the non-conductive contact object 92, the application activation unit 45 refers to the application or function corresponding to the gesture determined by the gesture input determination unit 35 from the application registration unit 55 and activates it.

  For example, as an application or function registered in the application registration unit 55, a music playback application, a camera function, a telephone call function, or the like is possible.

  According to the fifth modification of the first embodiment, as in the fourth modification of the first embodiment, the touch panel unit 10 can be used even when the use restriction cancellation unit 16 does not release the use restriction release unit 16 using a password. By performing the gesture operation with the pen 92, it is possible to execute the operation intended by the user while maintaining high security. Moreover, compared with the modification 4 of 1st Embodiment, there exists an advantage that a some application and function can be operated.

(Modification 6 of the first embodiment)
Next, Modification 6 of the first embodiment will be described with reference to FIG. FIG. 13 is a block diagram illustrating a configuration of a location related to canceling the use restriction in the terminal device according to Modification 6 of the first embodiment. As can be seen by comparing FIG. 13 with FIG. 2 (first embodiment), a contact area determination unit 36 is newly added in FIG. 13. The contact area determination unit 36 directly inputs outputs from the first and second touch panels 11 and 12, calculates a contact area when the user operates the touch panel unit 10, and the contact area is larger than a predetermined value. It is determined whether or not. Then, if it is determined that the value is larger than the predetermined value, the control unit 2 is instructed to change the operation screen for allowing the user to input the password shown in FIG. 7 to the predetermined screen. If the contact area is larger than the specified value, for example, the user may be operating with gloves on, and a screen with a touched letter or number that is easy to operate when entering a password. It is preferable to change to.

  According to the sixth modification of the first embodiment, it is possible to prevent an erroneous operation at the time of canceling the use restriction and to provide a comfortable operation environment for the user.

(Modification 7 of the first embodiment)
Next, Modification 7 of the first embodiment will be described with reference to FIG. As shown in FIG. 14, the modification 7 of 1st Embodiment differs in the order of the process of the use restriction cancellation | release part 16 and the contact target determination part 14 from FIG. 4 (1st Embodiment). FIG. 14 is a flowchart showing an operation of canceling the use restriction in the terminal device according to Modification 7 of the first embodiment.

  In FIG. 14, the user presses the password on the touch panel unit 10 (S21).

  Next, the contact object determination unit 14 detects whether or not there is a difference between the first detection result C1 and the second detection result C2 (S22). Specifically, it is detected whether the signal indicating that the depression is included in the first detection result C1 and the second detection result C2 is at a high level in common. When it is detected that the common level is high (in the case of No in step S22), it is determined that there is no difference between the first detection result C1 and the second detection result C2. It is determined that the contact object 91 has been used (S23). Next, it is determined whether or not the character code of the password included in the first detection result C1 or the second detection result C2 matches the password C0 (S24). When it determines with Yes in step S24, 1st use restriction cancellation | release is performed (S25). Moreover, when it determines with No in step S24, it returns to step S21.

  On the other hand, when it is detected that the signal included in the first detection result C1 and the second detection result C2 indicating that the button is pressed is not in common at the High level (Yes in step S22). Is determined that there is a difference between the first detection result C1 and the second detection result C2, and it is determined that the non-conductive contact object 92 has been used (S26). Next, it is determined whether or not the character code of the password included in the first detection result C1 or the second detection result C2 matches the password C0 (S27). If it is determined as Yes in step S27, the second usage restriction release is performed (S28). Moreover, when it determines with No in step S27, it returns to step S21. As described above, in the seventh modification of the first embodiment, after determining whether the contact target is conductive / non-conductive, it is determined whether the passwords match.

  As described above, according to the modified example 7 of the first embodiment, the order of processing in the use restriction release unit 16 and the contact object determination unit 14 is changed with respect to the first embodiment. There are obtained results similar to those of the first embodiment.

(Second Embodiment)
Next, a second embodiment will be described. In the first embodiment, when the user inputs the password, the content of the usage restriction cancellation is changed according to which of the conductive / non-conductive contact objects is used. In the second embodiment, a contact object to be used when the user performs an operation input is specified, and the operation input is accepted only when the contact object used by the user matches the specified contact object. That's it. FIG. 16 is a block diagram illustrating a configuration of a location related to operation input permission in the terminal device 101 according to the second embodiment. As can be seen by comparing FIG. 16 with FIG. 2 (first embodiment), in FIG. 16, an operation input permission unit 17 is provided instead of the use restriction release unit 16 of FIG. In the first and second detection units (21, 22) of the first embodiment, the pressed coordinates output from the first and second touch panels (11, 12) are converted into character codes. However, in the second embodiment shown in FIG. 16, the pressed coordinates are output as they are without being converted into character codes.

  As shown in FIG. 16, the operation input permission unit 17 receives the contact / non-conductivity C3 signal of the used contact object from the contact object determination unit 14 and the contact specified by the control unit 2. The conductive / non-conductive C5 signal of the object is input, and it is determined whether or not the signal C3 and the signal C5 match. When the two match, the input operation input is accepted, and then an operation corresponding to the operation input is performed. On the other hand, if they do not match, the input operation input is not accepted and no operation is performed. In addition, since it is the same as that of the terminal device 1 which concerns on 1st Embodiment, the component other than the above in the terminal device (101 of FIG. 3) which concerns on 2nd Embodiment attaches | subjects the same referential mark, and overlaps. Description is omitted.

  Next, the operation of the terminal device 101 according to the second embodiment will be described in detail with reference to FIG. FIG. 17 is a flowchart showing the operation of the terminal device 101. In the terminal device 101, it is assumed that an application screen (a screen displaying a list of icons of installed applications) is displayed on the display unit 13 and is waiting for an operation input from the user.

  In FIG. 17, it is assumed that the control unit 2 of the terminal device 101 has previously designated an operation input as a pen (non-conductive contact object) 92 (S11). Next, the first and second detection units (21, 22) determine whether or not there is an operation input from the user (S12). If an operation input is detected (Yes in step S12), it is next determined whether or not there is a difference between the first detection result C1 and the second detection result C2 (S13). When there is no difference in the detection result (No in step S13), it is determined that the used contact object is the conductive contact object 91 (S14). On the other hand, when there is a difference between the detection results (Yes in step S13), it is determined that the used contact object is a non-conductive contact object 92 (S15).

  Next, it is determined whether the used contact object determined in step S14 or S15 matches the contact object specified in step S11 (S16). If it is determined that they match (Yes in step S16), the user's operation input in step S12 is accepted (S17). On the other hand, when it is determined that they do not match (when it is determined No in step S16), the operation input is not accepted.

  Specifically, when the user taps an icon of an application with the finger (conductive contact object) 91 in step S12 and tries to start the application, the contact object used in step S16 is Since the specified contact object is a non-conductive contact object 92 with a finger (conductive contact object) 91, it is determined that they do not match, and an operation input by the user tapping an application icon is accepted. Absent.

  On the other hand, when the user taps the application icon with the pen (non-conductive contact object) 92, it is determined in step S16 that they match, and the operation input by the user tapping the application icon is The application is accepted and activated.

  As described above, according to the terminal device 101 of the second embodiment, when the designated contact object is not used by designating the conductivity / non-conductivity of the contact object of the operation input. Since it is possible not to accept the operation input, the effect of restricting the use by a third party other than the user can be obtained, and the security can be enhanced.

(Modification 1 of 2nd Embodiment)
Next, Modification 1 of the second embodiment will be described in detail with reference to FIG. FIG. 18 is a block diagram illustrating a configuration of a location related to operation input permission in the terminal device 101 according to the first modification of the second embodiment. As can be seen by comparing FIG. 18 with FIG. 15 (second embodiment), in FIG. 18, a designated contact object switching unit 18 and a contact object registration unit 19 are newly added. Components other than those described above are the same as those in the second embodiment, and are given the same reference numerals, and redundant descriptions are omitted.

  In FIG. 18, the designated contact object switching unit 18 switches the conductive / non-conductive signal C5 of the contact object designated on the operation screen. Specifically, all the operation screens used in the terminal device 101 are managed by screen numbers, and the contact object registration unit 19 has conductivity / non-conductivity of the contact objects that allow operation input for each screen number. Sex is registered. However, screens that are not registered accept operation input regardless of conductivity / non-conductivity without specifying conductivity / non-conductivity. As shown in FIG. 18, when the screen number displayed on the display unit 13 is input from the control unit 2 to the designated contact object switching unit 18, the designated contact object switching unit 18 With reference to the registration unit 19, the conductivity / non-conductivity of the designated contact object registered in the screen number is read out as a signal C5.

  For example, in the contact object registration unit 19, a normal operation screen registers a finger (conductive contact object) 91, and an operation screen for performing an important operation input uses a pen (non-conductive contact object) 92. sign up. For operation screens for performing important operation inputs, it is effective to register, for example, operation inputs related to accounting, operation inputs related to data deletion, operation inputs for reset operations, operation inputs for final decision operations, etc. is there. When the operation with the pen 92 is required, the user is requested to perform the operation with the pen 92 by notifying the user on the display screen. When an operation with the pen 92 is requested, the user switches the contact object from the finger 91 to the pen 92 and inputs an operation.

  As described above, in the first modification of the second embodiment, when an important operation input is performed, the user is warned by requesting an input with a designated contact object (for example, the pen 92). As a result, an effect of reducing user's erroneous operation can be obtained. Conventionally, when an important operation is to be performed by the user, an operation for confirming “Is this OK? Yes / No” is performed by the user to reduce erroneous operations. On the other hand, according to the first modification of the second embodiment, the user can be alerted by requesting the input with the pen 92, so the operation for confirmation by the above Yes / No is eliminated, A single operation input can be performed.

(Modification 2 of the second embodiment)
Next, Modification 2 of the second embodiment will be described in detail with reference to FIG. FIG. 19 is a block diagram illustrating a configuration of a location related to operation input permission in the terminal device 101 according to the second modification of the second embodiment. As can be seen by comparing FIG. 19 with FIG. 18 (Modification 1 of the second embodiment), in FIG. 19, a contact object registration unit 29 is provided instead of the contact object registration unit 19 of FIG. . The contact object registration unit 29 designates a specific area of the operation screen in the coordinate range, and registers the conductivity / non-conductivity of the contact object in the specific area. Then, the designated contact object switching unit 18 acquires input coordinates from the touch panel unit 10, determines whether or not the input coordinates are in a specific area registered in the contact object registration unit 29, and is in the specific area. Is determined, the conductivity / non-conductivity of the contact object designated in the specific region is read out and output as a signal C5.

  As a specific area to be registered in the contact object registration unit 29, as in the first modification of the second embodiment, an important operation input is specified to be input with the pen 92 in the specific area of the screen. For example, an operation input related to charging, an operation input related to data deletion, an operation input to perform a reset operation, an operation input to perform a final determination operation, and the like are registered to be input with the pen 92 in a specific area of the screen, respectively. And effective.

  As described above, in the second modification of the second embodiment, as in the first modification of the second embodiment, an effect of reducing the user's erroneous operation when performing an important operation input can be obtained.

(Third embodiment)
Next, a third embodiment will be described in detail with reference to FIG. FIG. 20 is a block diagram illustrating a configuration of a location related to the use restriction cancellation in the terminal device 1 according to the third embodiment. In the third embodiment, similarly to the first embodiment, the user is allowed to input a password to cancel the use restriction of the terminal device 1. However, the third embodiment is different in that when a password is input, the conductivity / non-conductivity of a contact object used for each character is designated.

  In FIG. 20, a usage restriction releasing unit 46 is provided instead of the usage restriction releasing unit 16 of FIG. The usage restriction canceling unit 46 receives from the contact object determining unit 14 a conductive / non-conductive C3 signal of the contact object used for each character and a preset password C8. However, the password C8 is a password in which a finger / pen is designated for each character. In the use restriction release unit 46, the contents of the first and second detection results C1, C2 and the password C8 match, and the conductive / nonconductive C3 of the contact object used for each character. The use restriction release unit 46 releases the use restriction only when the signal and the conductivity / non-conductivity of the contact object of the password C8 designated for each character match in all characters. A signal is transmitted to the control unit 2. The control unit 2 releases a predetermined usage restriction.

  Next, the operation of the third embodiment will be described using a specific example. Password C8 is “12345”, “1”, “3” and “5” are fingers (conductive contact object) 91, “2” and “4” are pens (non-conductive contact object) 92, It is assumed that it is set in advance. When the user inputs the password “12345” while switching the order of the finger 91 → pen 92 → finger 91 → pen 92 → finger 91 in the password input area 93 of the unlock screen shown in FIG. The use restriction release unit 46 determines that the content of the password and the conductivity / non-conductivity of the contact object match for all characters, and the use restriction is released. In other cases, even if the contents of the passwords are the same, the lock release screen is not released if the input is not made using the contact object designated for each character.

  As described above, according to the terminal device according to the third embodiment, even if the content of the password is leaked or guessed, it is not canceled unless the combination of the contact objects used is matched, Security can be increased.

(Fourth embodiment)
Next, a fourth embodiment will be described with reference to FIG. In the fourth embodiment, among the touch panel units 10 of the first to third embodiments, the second touch panel is used as a photo sensor type touch panel, which is incorporated in the display unit. As shown in FIG. 21, the display unit 103 with a built-in photosensor touch panel is an active matrix liquid crystal panel in which photosensors are arranged at predetermined intervals. As described above, a method of incorporating a photosensor in a liquid crystal panel is disclosed in Patent Document 3, for example.

  Similar to the resistive film type touch panel 12, the display unit 103 including the photo sensor type touch panel operates as a touch panel that detects regardless of the conductivity / non-conductivity of the contact object. Therefore, even if the touch panel unit 10 and the display unit 13 in each of the first to third embodiments are replaced with the capacitive touch panel 11 and the display unit 103 incorporating the photo sensor touch panel shown in FIG. It operates in the same way.

  As described above, according to the terminal device according to the fourth embodiment, the same effects as those of the first to third embodiments can be obtained. Moreover, in 4th Embodiment, there exists an advantage that a terminal device can be reduced in size by incorporating a 2nd touchscreen into a photosensor system in a display part.

  In the present invention, the first touch panel and the second touch panel are not limited to a capacitive touch panel and a resistive touch panel, respectively. That is, as shown in the fourth embodiment, the first touch panel is a touch panel that detects a conductive contact object and detects a non-conductive contact object, and the second touch panel is a contact object. Any type of touch panel can be applied as long as the object is detected regardless of conductivity / non-conductivity.
