  Hereinafter, an embodiment of a mobile communication apparatus to which an information processing apparatus according to an embodiment of the present invention is applied will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a mobile communication apparatus according to an embodiment of the present invention. The mobile communication device includes a control unit 11 that controls the entire device, a communication unit 12, an antenna 12a that transmits and receives radio waves to and from a base station (not shown) of the mobile communication network, and a transmission and reception unit 13. The communication unit 14 includes a speaker 14 a used for receiving a voice, a microphone 14 b used for transmitting, a display unit 15, an input unit 16, and a touch pad 17. The touch pad 17 is installed so as to cover the display screen of the display unit 15 and constitutes a touch panel together with the display unit 15.

  As functions related to the present invention realized by executing the program, the control unit 11 includes a touch panel function 11-1, a key lock function 11-2, an authentication function 11-3, and a password change function 11. -4.

  The operation of each part of the mobile communication apparatus configured as described above according to the embodiment of the present invention will be described with reference to FIG.

  The communication unit 12 outputs a high-frequency signal transmitted from the base station and received by the antenna 12a to the transmission / reception unit 13, and transmits a high-frequency signal output from the transmission / reception unit 13 to the base station via the antenna 12a.

  The transmission / reception unit 13 amplifies, frequency-converts and demodulates the high-frequency signal from the communication unit 12, and sends the digital voice signal obtained thereby to the call unit 14 and the control signal to the control unit 11. Further, the digital audio signal output from the communication unit 14 and the control signal output from the control unit 11 are modulated, frequency-converted and amplified to obtain a high-frequency signal, which is sent to the communication unit 12.

  The calling unit 14 converts the digital audio signal output from the transmitting / receiving unit 13 into an analog audio signal, amplifies it, and sends it to the speaker 14a. The analog audio signal output from the microphone 14 b is amplified, converted into a digital audio signal, and transmitted to the transmission / reception unit 13.

  The display unit 15 is an organic EL display used for a display prompting the user to operate, a display of contents operated by the user, a display of an operation state of the apparatus, or a backlit LCD. 11, image data including characters, numbers, and icons is displayed, and the displayed data is instructed from the control unit 11 in response to an input operation from the input unit 16 or an incoming signal. Switch by receiving.

  Here, a part or all of the displayed data is a soft key, and when contact of a finger or the like to the position where the soft key is displayed on the touch pad 17 is detected, as will be described later, the control unit 11. Operates as if the key associated with the soft key is pressed. Since the touch pad 17 is installed so as to cover the display screen of the display unit 15, the position of the touch pad 17 touched by the finger and the soft key touched by the finger or the like will be displayed thereafter. Use it without distinguishing the position, and give a simple explanation.

  The input unit 16 has at least a function key for instructing power-on of the device. In addition to the key, the input unit 16 designates a telephone number of a communication partner, and hiragana characters, alphabetic characters and symbols by a toggle type input method. It may include numeric keys for inputting characters, a plurality of function keys including a cursor movement, an arrow key indicating a display scroll instruction, a determination key, an incoming call key, and an end call key. When the key of the input unit 16 is pressed, the identifier of the key is notified to the control unit 11.

  The touch pad 17 is a transparent or semi-transparent electrostatic or pressure-sensitive film-like sensor installed so as to cover the display screen of the display unit 15. The control unit 11 is notified of the coordinates of the determined position. When a finger or the like touches a plurality of positions, a plurality of coordinates are notified. Alternatively, the average value of the coordinates of the touched position is notified. Here, when the touch pad 17 can detect the distance to the finger or the like, the contact includes that the distance is less than a predetermined distance threshold.

  The touch panel function 11-1 stores which area is a soft key in the data displayed on the display unit 15 and a key identifier associated with the soft key. Here, this key may or may not be a key provided in the input unit 16. When a notification that a finger or the like is touched is received from the touch pad 17, it is determined whether or not the data displayed at the touched position is a soft key.

  When the key is a soft key, the touch panel function 11-1 causes the control unit 11 to perform the same operation as when the key identifier associated with the soft key is notified. Therefore, hereinafter, the input does not matter whether it is an input by a key operation of the input unit 16 or an input via the touch panel function 11-1.

  Further, when the touch panel function 11-1 receives a notification that a finger or the like has touched a plurality of soft key areas, the touch panel function 11-1 prompts the user to touch any one of the areas. When a notification that a finger or the like has touched the middle of the plurality of soft key areas is received, the user is similarly prompted to touch any of those areas.

  In a predetermined case, the key lock function 11-2 causes the authentication function 11-3 to perform authentication after performing key lock on the device. Here, the predetermined case is one or more of the following cases. The first case is when a predetermined lock key is input. Second, there is a case where no input is performed for a predetermined time. Third, the device is a device that can be opened and closed, and the device is placed in a closed state.

  When the device is key-locked, the key-lock function 11-2 does not perform an input operation other than for authentication by the authentication function 11-3. Then, the key lock is released in response to the notification of the successful authentication of the user of the apparatus. However, when the device is key-locked, it performs an input operation for a limited purpose such as power-off, incoming call, specific telephone number, for example, call to police.

  The authentication function 11-3 starts the operation and authenticates the user of the device when there is an input when the device is key-locked and when activation is performed from each part of the device. . That is, first, soft keys consisting of 1 to 9 and 0 are displayed on the display unit 15. And the PIN code which consists of a 4-digit number is input with those soft keys via the touch panel function 11-1. When the personal identification number and the personal identification number stored in the control unit 11 are equal, a successful authentication is notified. If they are not equal, the authentication failure is notified.

  The personal identification number changing function 11-4 updates the personal identification number stored in the control unit 11. That is, first, the authentication function 11-3 is activated to authenticate the user of the apparatus. After the authentication is successful, a soft key consisting of 1 to 9 and 0 is displayed on the display unit 15 to input the password for the first time. Then, the soft key consisting of 1 to 9 and 0 is displayed again on the display unit 15 to input the password for the second time. When the password entered at the first time is equal to the password entered at the second time, the password change function 11-4 updates the password stored in the control unit 11 to the same password. Remember.

  Next, a user interface for preventing an erroneous operation through the touch panel in the mobile communication device having the above configuration will be described. First, with reference to the flowchart shown in FIG. 2, the operation of updating the password by the password change function 11-4 will be described.

  The personal identification number changing function 11-4 starts an operation for updating the personal identification number in response to a predetermined user input (step S101), and causes the authentication function 11-3 to authenticate the user of the apparatus (step S102). Then, the first personal identification number is input by the first soft key arrangement (step S103), and then the second personal identification number is input by the second soft key arrangement (step S104), and the first personal identification number is entered. And whether or not the second password is equal (step S105).

  If these passwords are equal, the password change function 11-4 updates and stores the password in the control unit 11 (step S106), and ends the password update operation (step S107). On the other hand, if they are different, the password update operation is immediately terminated (step S107). Note that if the password is not stored in the control unit 11, the authentication operation in step S102 is not performed. In step S106, a new password is stored (not shown).

  With reference to the example of FIG. 3, the display on the display unit 15 when the first personal identification number is input by the first soft key arrangement in step S <b> 103 will be described. This display includes an input character display 15a displayed at the top, a soft numeric keypad 15b displayed at the center, and first soft function keys 15c displayed from left to right at the bottom,. It consists of a software function key 15d. Here, n is a natural number of 2 or more.

  In the input character display 15a, a character “*” is additionally displayed every time one character of the password is input. The reason why the input character is not displayed is to prevent the character from being known to anyone other than the user of the apparatus.

  The soft numeric keys 15b in the first soft key arrangement have numbers 1 to 9 and 0 equal to the dial key arrangement of the telephone and are arranged in 4 rows and 3 columns. In the fourth row, “0” is arranged in the center. This arrangement is defined and well known by the International Telecommunication Union (ITU), so that it is possible to easily input an intended number.

  The soft numeric keypad 15b in the first softkey arrangement may be a well-known arrangement as described above, and is not limited to the arrangement described above, and is a numerical value of a calculator determined by the International Organization for Standardization (ISO). An array of keys or a PC numeric keypad may be used. Moreover, the numbers 1-9 and 0 may be arranged in one or more columns in this order.

  The first soft function key 15c,..., The nth soft function key 15d are soft keys used for inputting a predetermined function. The first soft function key 15c displays “Return” and is used for inputting a function for immediately terminating the operation of the password change function 11-4. The n-th software function key 15d displays “cancel one character” and is used to input a function for canceling the last input character among the passwords input by the password change function 11-4. (Neither is shown in the flowchart of FIG. 2).

  With reference to the example of FIG. 4, the display on the display unit 15 when the second personal identification number is input by the second soft key arrangement in step S <b> 104 will be described. In this display, the soft numeric keypad 15b is different from the display when the first softkey arrangement described with reference to FIG. 3 is used for input. Therefore, the soft numeric keypad 15b in the second softkey arrangement will be described.

  As in the soft numeric keypad 15b in the first softkey layout, the numbers 1 to 9 and 0 are arranged in 4 rows and 3 columns, and the fourth row has a center on the softkeypad 15b in the second softkey layout. 1 character is arranged in the. However, unlike the soft numeric keypad 15b in the first softkey arrangement, the position of each number is determined based on, for example, a random number.

  The soft numeric keys 15b in this arrangement are not limited to being arranged in 4 rows and 3 columns. It is essential that the soft numeric keypad 15b in the second softkey arrangement is different from the soft numeric keypad 15b in the first softkey arrangement in the position where at least some of the numbers are displayed.

  As a result, even if the wrong position of the soft numeric keypad 15b, for example, the position of the number displayed to the right of the number intended to be input is touched as in the soft numeric keypad 15b in the first softkey arrangement, The second password entered by the soft numeric keypad 15b in the key layout is unlikely to be equal to the first password entered by the soft numeric keypad 15b in the first softkey layout. Therefore, it is possible to ignore the possibility that the password which is not intended by the user, that is, the password which is not stored in the user's memory is updated and stored.

  In the above description, the password change function 11-4 has input the new password that is updated and stored twice. However, the present invention is not limited to this. If the input is performed twice or more times and the same password is input twice, the password may be updated and stored in the control unit 11. In the second and subsequent inputs, the arrangement of numbers displayed in the soft numeric keypad 15b is different from the arrangement used in the previous input.

  Next, with reference to the flowchart shown in FIG. 5, the operation of prompting the touch to the limited soft key by the touch panel function 11-1 will be described.

  When the touch panel function 11-1 receives a notification that a finger or the like has touched a plurality of soft key areas, and receives a notification that a finger or the like has touched the middle of the plurality of soft key areas, The operation of prompting the user to touch a limited soft key, which is determined to have been intended by the user, is started (step S201). Then, a display for prompting contact with the plurality of soft keys (hereinafter referred to as specific soft keys) is displayed on the display unit 15 (step S202). The maximum number of specific soft keys is, for example, 4 when the shape of the soft keys is a quadrangle and arranged in a grid pattern, but differs depending on the shape of the soft keys.

  Here, when the touch panel function 11-1 starts an operation for prompting the user to touch the limited soft key, the display unit 15 displays the display shown in FIG. Taking the case of “1” and “2” as an example, a display for prompting contact with a specific soft key will be described. FIG. 6 shows a first display for prompting the user to touch a specific soft key. Compared with the display shown in FIG. 3, the soft numeric keypad 15b is not displayed and the first modified soft numeric keypad 15e is displayed. ing. The n-th soft function key 15d displays “input all characters” instead of “cancel one character”.

  The first modified soft numeric keypad 15e is larger than when each of the specific softkeys is displayed as a part of the soft numeric keypad 15b, and is displayed with an interval between the specific softkeys. By this display, it is impossible to touch the “3” to “9” and “0” soft keys that are included in the soft numeric keypad 15b but are not included in the first modified soft numeric keypad 15e. In addition, the numbers corresponding to those soft keys are not input, and the effect of prompting the user to touch specific soft keys is great.

  FIG. 7 shows a second display for prompting the user to touch a specific soft key. Compared with the display shown in FIG. 3, the soft numeric keypad 15b is not displayed, and the second modified soft numeric keypad 15f is displayed. ing. The second modified soft numeric keypad 15f has the same size and the same content as the soft numeric keypad 15b, but only the specific softkey has the same display form as the soft numeric keypad 15b, and other parts are grayed out and displayed. Has been.

  Further, the display other than the second modified soft numeric key 15f, the first soft function key 15c,..., The nth soft function key 15d have the same display form as the display shown in FIG. The layout is displayed. The n-th soft function key 15d displays “input all characters” instead of “cancel one character”.

  Here, the grayout is a display with reduced luminance and / or a display with reduced saturation. In other words, the display is darker and / or the color is poorer. The grayout includes gray display and further, no display. FIG. 7 shows a display grayed out by hatching.

  Here, the specific soft keys that are not grayed out, the first soft function key 15c,..., The nth soft function key 15d are soft keys, and the other parts are not soft keys. This makes it clear to the user what input is possible. That is, it becomes apparent at a glance that the grayed-out display does not play a role (in this case, input) by giving a sunk impression.

  It should be noted that even if a portion that was a soft key in the display shown in FIG. 3 and a portion that is not a soft key in FIG. 7 is touched, the touch is not treated as an input, and the user is grayed out. It can be easily understood that the display does not play a role.

  Furthermore, the grayed-out display is effective in reducing the power consumption of the display unit 15 and preventing its deterioration. Here, the deterioration is a part or all of a decrease in luminance, a decrease in saturation, and unevenness in emission color depending on the position of the display screen called burn-in. In the case of an organic EL display having a self-luminous structure without requiring a light source such as a backlight, these effects are remarkable.

  Even in an LCD with a backlight, by reducing the luminance of part of the backlight and performing gray-out display, it is effective in reducing power consumption and preventing backlight deterioration.

  Returning to the description of the operation of the touch panel function 11-1 with reference to FIG. In step S202, after the display for prompting contact with the specific soft key is displayed on the display unit 15, the touch panel function 11-1 checks the touched soft key (step S203). If the soft key is a specific soft key, an input process identified by the soft key is performed (step S204), and the display unit 15 starts the operation in step S201 from a display prompting the user to touch the specific soft key. The display before the display is restored (step S205), and the operation for prompting contact with a limited soft key is terminated (step S206).

  On the other hand, when the soft key touched in step S203 is one of the first soft function key 15c,..., And the nth soft function key 15d, the touch panel function 11-1 displays the display on the display unit 15. The display that prompts the user to touch the specific soft key is restored to the display before the operation is started in step S201 (step S205), and the operation that prompts the user to touch the limited soft key is terminated (step S206).

  The operation corresponding to the touched soft function key (any one of the first soft function key 15c,..., The nth soft function key 15d) is an operation that prompts the user to touch a limited soft key. This is performed by each unit of the device after the end, but when the n-th soft function key 15d is touched, each unit of the device does not perform any processing. That is, when the display prompting the user to touch a specific soft key shown in FIG. 6 or FIG. 7 is displayed and the user of the device intends to touch a soft key other than “1” and “2”, Touching the n soft function key 15d with a finger or the like, the touch panel function 11-1 restores the display capable of inputting all the characters shown in FIG. 3, and continues the operation of the password change function 11-4. .

  In the above description, the input of a personal identification number which is a string of numbers is taken as an example. However, the present invention can be applied to input of any other object. For example, it can be used when inputting a password that is a string of alphabetic characters and numbers. In this case, the arrangement of the soft keys corresponding to the alphabet letters and numbers in the first soft key arrangement displayed in step S103 may be well-known, for example, the arrangement of the alphabet letter keys in the keyboard defined in Japanese Industrial Standards. And In addition, the alphabet letters are arranged in one line or plural lines in the order of 1 to 9 and 0 in the order starting from A and ending in Z.

  When the password includes kana characters, the arrangement of the soft keys corresponding to the kana characters in the first soft key arrangement is an arrangement of kana character keys on a keyboard defined in Japanese Industrial Standards. Or it is set as a 50-sound table arrangement. Furthermore, the present invention displays a menu composed of menu items that are soft keys, and can be used to input an instruction to select a menu item in the menu. In this case, the first soft key arrangement displayed in step S103 is always the same. If menu items are numbered, the menu items are in order. Further, the present invention can be used for selecting an icon that is a soft key and inputting an instruction to execute an application indicated by the icon.

  Moreover, although the process of repeating the same input has been described as being performed when a new password is input, the present invention is not limited to this case. This can be used when entering a new password. In addition, for example, when a serious problem occurs due to selection of an incorrect item, for example, when one of the items is an instruction to initialize the device, the device is initialized by selecting the item multiple times. Can be used to ensure that

  Although the above description has been made taking an example in which the present invention is applied to a mobile communication device, the present invention is not limited to this. The present invention can naturally be applied to any information processing apparatus including a fixed communication apparatus and a personal computer. The present invention is not limited to the above configuration, and various modifications are possible.
