Description

  The present invention relates to a mobile terminal device, an information search method and a program, and more particularly to a mobile terminal device having a display unit, an information search method and a program.

  A conventional method for searching for data in a mobile phone will be described below (see, for example, Patent Document 1). The data includes data (various functions, ringtones, etc.) pre-installed in the mobile phone and user-specific data (e-mail, download image, etc.). The mobile phone has many functions that can be set by the user, and also has a large amount of user-specific data, and a huge amount of data is stored in the memory of the mobile phone.

  First, a conventional method for a user to execute a desired function in a mobile phone will be described with reference to FIG. FIG. 7 shows a transition example of the display screen of the display unit of the mobile phone.

  When the user changes the ring tone, the following operation is performed. The screen 71 is a standby screen. First, the user calls a function in the state of the standby screen 71. That is, the function call button in a plurality of operation buttons included in the operation unit of the mobile phone is pressed. Thereby, the item list display screen 72 of various functions is displayed on the display unit. Since many types of functions are set by a user in a mobile phone, it is difficult to display a list of all functions at once on a small display such as a mobile phone. Therefore, each function is classified into several types. For example, the selection of the ringtone and the setting of the ringtone volume are classified as “sound”. Here, various classifications are referred to as major items, and six major items are listed as shown in the screen 72.

  Next, when a “sound” item is selected and determined by a cursor operation using the operation unit as shown on the screen 73, a screen 74 is displayed on the display unit. On the screen 74, a list of functions classified as “sound” is displayed. Then, as shown in the screen 75, the user selects a target function with the cursor button of the operation unit, and presses the determination key of the operation unit in a state where the target function is displayed with the cursor, thereby setting the target ring tone. A screen 76 is displayed. The cursor display is a display performed by operating the cursor button up and down (left and right).

  When the cursor display on the screen 74 is not the target function, the user performs the cursor operation until the target function name is displayed by moving the cursor display up and down. Since the number of lists displayed on the screen is limited, when the function name exceeds the screen display number, the screen is switched at any time by moving the cursor display up and down to display all function names. If the target function is the 20th in the list, the cursor operation is performed 20 times at the maximum.

  Next, a conventional method for a user to browse a desired mail on a mobile phone will be described with reference to FIG. 8A and 8B show transition examples of the display screen of the display unit of the mobile phone.

  The mobile phone can store incoming mail, outgoing mail, and the like. The number of saved items is enormous, but the number that can be displayed on the mail list screen is limited. When the user wants to search for a specific mail from the received mail, the user performs the following operation.

  First, when the user presses a mail button assigned to the operation unit, a mail screen 81 is displayed on the display unit. On the mail screen 81, a received mail list, a transmitted mail list, a stored mail list, a new mail creation, and the like can be selected. When “received mail” is selected here, a received mail list screen 82 is displayed. The received mail list screen 82 displays only the date and title of the received mail, and there is little information about the mail obtained from the screen 82. For this reason, if the user does not remember the date or title of the mail, the user must select one item at a time and check the contents. In the screen 82, it is assumed that each mail is displayed from the newest in order of date.

  When the user selects one mail with the cursor button and presses the enter button as shown on the screen 83, the recipient of the selected mail and its contents are displayed on the display unit as shown on the screen 84. If it is not the recipient or content that the user was looking for, the screen 84 is closed and the screen returns to the received mail list screen 82, and mail selection (screen 83) and content confirmation (screen 84) are repeated. If there is no target mail in the currently displayed received mail list, the mail is displayed sequentially by lowering the cursor display with the cursor button. If the target mail is the 50th mail in the list, the above operation is repeated up to 50 times.

  In the received mail list screen 82, the mails are arranged in the order of date, but the user can change the display method. For example, the order of the oldest date, display by name, display by address, etc. can be set. Therefore, every time the user searches from the received mail list, the display method suitable for the purpose of the search is switched by the user setting, and after the change, the target mail can be searched from the list display.

  For example, as shown in FIG. 8B, when switching from the received mail list screen 91 (82) arranged in order of date to display in order of name (in the order of “Aiueo”), in the state where the screen 91 is displayed, A list display switching setting screen 92 is displayed by pressing a predetermined button. Then, by selecting and determining the name order, a list of received mails arranged in name order as shown in the screen 93 is displayed. Therefore, it is not necessary to confirm the contents of mail that is not the target name. However, if the name is assigned to the back of the list, the cursor operation is repeated until the target mail is displayed on the screen 93, which also takes time.

JP 2000-261544 A (page 2-3, FIG. 9-10)

  As described above, conventionally, when calling various functions provided in a mobile phone, it takes too much time to search for all functions in a list display. Since there are many types of functions in mobile phones, the classification is often hierarchical. For this reason, the number of button operations increases to reach the target function setting screen. In addition, it is often difficult to find a target function from among the hierarchized functions if the function is not frequently used.

  In addition to various functions, there is a lot of data in the memory of the mobile phone, and the number of data that can be saved by the user is enormous. With the development of mobile phone technology, it is considered that the data provided in advance in the mobile phone and the data that can be stored in the mobile phone will increase in the future. However, as the amount of data increases, the effort for the user to search for specific data is increasing.

The operation unit 8 is composed of a plurality of keys for inputting a telephone number and selecting each function.

  The control unit 7 is connected to the wireless unit 2, the memory 3, the audio signal processing unit 4, the operation unit 8, and the display unit 9. The control unit 7 controls these units. The control unit 7 monitors the operation unit 8, detects and determines a user operation, performs processing based on the operation, and controls the display unit 9 to perform various displays. The control unit 7 includes a CPU 10. The CPU 10 monitors the key press of the operation unit 8 and, when recognizing the key press, performs specific processing and causes the display unit 9 to display necessary information.

  In the mobile phone according to the first embodiment of the present invention, when the user wants to search for specific data, a character string related to the data is input on the keyword input screen. A button for calling a keyword input screen (hereinafter referred to as a help button) is assigned to the operation unit 8, and the keyword input screen is displayed on the display unit 9 when the help button is pressed.

  The help button is a button that can be used only when the data search can be performed. When the help button can be used, the character “help” is displayed on the display unit 9 so that the user can recognize this. . Otherwise, the help function (search function) cannot be used. The help function can be used on a normal standby screen, mail list screen, and the like, and cannot be used on a screen that does not require data search such as a screen during a call. When a keyword is entered on the keyword input screen and a search is started, data names related to the keyword are displayed in a list on the display unit 9. That is, a list of data names including the input keyword is displayed. It is also possible to perform a fuzzy search for a character string similar to the input keyword, and display a list of data names including the input keyword and data names including a character string similar to the input keyword.

  The operation of the mobile phone according to the first embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a flowchart showing the operation of the mobile phone according to the first embodiment of the present invention. In FIG. 2, when the help button is pressed, a keyword input screen is displayed (step S1), and the user inputs a keyword using the operation unit 8 (step S2). When the determination button of the operation unit 8 is pressed (step S3), the control unit 7 searches the data of the type corresponding to the display screen of the display unit 9 when the help button is pressed as the search target. Based on this, the search is started (step S4).

  For example, if the help button is pressed while a mail screen for selecting a received mail list, a sent mail list, a new mail creation, etc. is displayed on the display unit 9, the search target is searched as a sent mail and a received mail. Is done. For example, if the received mail list display screen is displayed, the search target is limited to the received mail. For example, if the item list display screen for various functions is displayed, the search target is limited to those functions. In addition, for example, if the standby screen is displayed, all data of the mobile phone (data provided in advance (various functions, ringtones, etc.) and user-specific data (e-mail, download image, Etc.)) is the search target.

  If there is data relating to the keyword as a result of the search in step S4 (step S5, YES), a list of data relating to the keyword as the search result is displayed on the display unit 9 (step S6). On the other hand, when there is no data relating to the keyword (step S5, NO), a message such as “no corresponding data” is displayed (step S9). In this case, the keyword can be input again by pressing the help button (steps S10 and S1).

  In the search result display in step S6, all the data names of the data related to the keyword are displayed in a list. If the data name of the target data exists in the list, the user selects the target data name using the operation unit 8 and presses the enter button (step S7), so that it corresponds to the selected data. Processing is performed by the control unit 7 (step S8).

  For example, when a search for various functions is performed, a list of function names including keywords is displayed (step S6). If the target function name exists in this list, the user selects the target function name using the operation unit 8 and presses the enter button (step S7), thereby setting the function corresponding to the selected function. A screen is displayed on the display unit 9 (step S8). When the hold key of the operation unit 8 is pressed, the search processing operation in the flowchart of FIG.

  As described above, in the search in step S4, since the type of data to be searched differs depending on the screen when the help button is pressed, the help function is called on each type of screen such as the item list screen of various functions and the mail screen ( Search data can be narrowed down by pressing the help button.

  A search when various functions are set as search targets will be described with reference to FIGS. 2 and 3. Here, a case where the user changes the ring tone will be described as an example. FIG. 3 is a diagram illustrating a transition example of the display screen of the display unit 9 when various functions are to be searched.

  When the help button is pressed on the large item list display screen 31 for various functions, the keyword input screen 32 is displayed (step S1). As shown in the screen 33, when the user inputs “ringtone” as a keyword and presses the enter button (steps S2 and S3), a keyword search for various functions as a search target is performed (step S4). When the search is completed and a function name including a keyword exists (step S5), the search result is displayed as shown on the screen 34 (step S6). The display of the search result is a list of function names including the input keyword “ring tone”. If there is a target function from the function list, the function setting screen corresponding to the selected function is displayed. Here, as shown in the screen 35, when the user moves the cursor display to “select ringtone” and decides using the operation unit 8 (step S7), the ringtone selection screen 36 is displayed (step S8). .

  Next, a search when the received mail is a search target will be described with reference to FIGS. 2 and 4. Here, a case where the user searches for mail from a specific person will be described as an example. FIG. 4 is a diagram illustrating a transition example of the display screen of the display unit 9 when the received mail is a search target.

  When the user selects and determines the received mail list using the operation unit 8 on the mail screen 41 that can select the received mail list, the transmitted mail list, the stored mail list, the new mail creation, etc., the received mail list display screen 42 is displayed. Is done. When the help button is pressed on the screen 42, a keyword input screen 43 is displayed (step S1), and the user inputs a sender name as a keyword as shown on the screen 44 (step S2). The search for received mail with a specific name is limited to the case where the name and e-mail address are registered in the memory 3 in advance in the address book registration, and the character string to be input by keyword input is registered in the address book. Name. However, it is not necessary to input the registered name as it is, and only a part of the registered name may be input as a keyword.

  As shown in the screen 44, when the user inputs “name A” and presses the enter button (steps S2 and S3), a keyword search for the received mail as a search target is performed (step S4). The search is performed from all received mails stored in the memory 3. Here, the number of stored received mails is set to 200, and all received mails with the name A retrieved from the maximum 200 are displayed as a list as shown on the screen 45 (steps S5 and S6). When the user selects and determines the received mail with the desired name A using the operation unit 8 on the screen 45 (step S7), the mail text of the selected received mail is displayed as shown on the screen 46 (step S8). . In the example of FIG. 4, the search is performed by name, but the character string to be input by inputting a keyword may be a mail title, date, mail address, or the like.

  In the conventional method, when the user wants to execute the target function, the user needs to perform button operations such as moving the cursor as needed from the list of function names displayed on the display unit until the target function is displayed. However, in the first embodiment of the present invention, the user can easily call the target function by simply pressing the help button, inputting a keyword, and making a decision.

  In addition, even if you do not know the target function name (data name), you can simply enter a keyword and data related to the keyword will be displayed. There is no need to check with a letter.

  In addition, since the type of data to be searched (function name, mail, download data, etc.) differs depending on the screen when the help button is pressed, the search data can be narrowed down and the user desired data can be found more easily. it can.

  In addition, as the amount of data increases with the development of mobile phones in the future, the search effort from the conventional list is increasing, but in the search method according to the first embodiment of the present invention, Even if the data in the memory increases, the user does not need to perform an operation, and the user can easily search for desired data by simply pressing the help button, inputting a keyword, and making a decision.

  In the above-described first embodiment of the present invention, the help function is called, that is, the keyword input screen is called by pressing a predetermined button in the operation unit 8 as a help button by the user. However, the user makes a call by selecting the “help” portion (this is referred to as a help button) displayed on the screen 31 or the screen 41 shown in FIGS. 3 and 4 by using the operation unit 8. You may do it.

  In the first embodiment of the present invention, only one keyword is input on the keyword input screen. However, two or more keywords may be input and a search may be performed based on these keywords. When inputting two or more keywords, “OR” or “AND” is used between the keywords.

  For example, when calling the setting screen of the standby screen, the search keyword is “screen OR display”. If the setting of the standby screen matches one of the two, it can be displayed in the search result list. If it is not known whether the data name relating to the standby screen setting in the memory 3 is registered as “screen” or “display”, the OR function is effective. If you want to set the mail ringtone, you can narrow down the search results by entering “Sound AND Mail” to search for data that matches both the sound and mail keywords.

  “OR” and “AND” described above may be input using symbols such as “,” “*” and the like. Alternatively, there may be two or three keyword input fields in the keyword input screen, and “OR” or “AND” can be selected between the keyword input fields.

  In addition, for the purpose of assisting the user in inputting keywords, a button is provided on the keyword input screen, and when the user selects the button using the operation unit 8, the keywords input in the past are displayed in a list. May be. In this case, when one keyword in the list is selected, the selected keyword is displayed in the keyword input field of the keyword input screen. If the keyword has been input once in the past, this function can be used to save time for keyword input operation.

  Further, in the first embodiment of the present invention, the search is performed using the type of data corresponding to the display screen of the display unit 9 when the help button is pressed, as in the first embodiment. Instead of calling the help function after switching the screen display, the user may be able to select the type of data to be searched on the keyword input screen. An example of transition of the display screen of the display unit 9 for explaining this is shown in FIG.

  2 and 5, when the user presses the help button while the standby screen 51 is displayed in order to call the function for setting the mail ringtone, the keyword input screen 52 is displayed (step S1). . “Type” is displayed on the screen 52, and when the user selects the “type” part using the operation unit 8, a screen 53 on which the type of data to be searched can be selected is displayed. A list of data types is displayed on the screen 53, and the user selects a type using the operation unit 8. If it is not necessary to select the type, select “None”.

  Here, in order to set the mail ringtone, the user selects “function setting” on the screen 53. When the selection is completed, the screen returns to the keyword input screen 54, and “function setting” is displayed in the type column. Then, the user inputs “mail” as a keyword and presses the enter button (steps S2 and S3). That is, in this example, in step S2, the user not only inputs a keyword but also selects a type to be searched.

  After step S3, a search is performed (step S4). In this example, the search in step S4 is performed using data of the type selected by the user as a search target. Therefore, in step S4, a search for various functions is performed, and a list of function names related to the keyword “mail” is displayed as shown on the screen 55 (steps S5 and S6).

  As described above, in the first embodiment of the present invention, when the help function is called on the standby screen, all data of the mobile phone is searched regardless of the type. All the data related to the mail is displayed as a search result. There is a possibility that all received mails, sent mails, etc. are displayed. In the first embodiment of the present invention, when the type is desired to be selected, the help function is called after switching the display screen. In the example shown in FIG. Any screen can be searched by selecting a desired type as a search target.

  Next, a second embodiment of the present invention will be described with reference to the drawings. With the development of mobile phones, functions for setting mobile phones are increasing rapidly. However, while the types of functions increase, the user cannot memorize all functions, and there are many cases in which only specific functions are used depending on the user. Especially for newly added functions, it is often difficult to determine what settings can be made and what settings should be performed even if only the function names displayed on the function setting screen are viewed. The user will no longer use the feature. The instruction manual describes each function, but a user who normally uses a mobile phone often does not have the instruction manual at hand.

  Therefore, in the second embodiment of the present invention, as a help function, when a help button is pressed on a screen displaying a function name, a detailed description of the function is displayed on the display unit 9. To do. The mobile phone according to the second embodiment of the present invention has the same configuration as that shown in FIG.

  The function name is displayed on the screen for setting each function, and the operation moves to the operation for actually setting the function by pressing the enter button. Here, a function called “incoming answer setting” will be described with reference to FIG. FIG. 6 is a diagram showing a transition example of the display screen of the display unit 9 for explaining the help function of the second embodiment of the present invention.

  The incoming answer is to set an operation when the user presses a button assigned as an “any key” other than the off-hook button or the end button of the operation unit 8 when receiving an incoming call. In the incoming answer setting, two types of settings “any key answer” and “quick silent” shown on the screen 62 can be set. When the any key answer is selected by the user, the operation is set so as to shift to a call state when an any key other than the off-hook button or the end button is pressed when an incoming call is received. On the other hand, when quick silent is selected by the user, the operation is set so that the ringing tone is stopped when the any key is pressed at the time of incoming call and the incoming call is continued as it is.

  Such a function is a function peculiar to a mobile phone, and some users cannot understand what the function is just by looking at the name of the function. Therefore, in the second embodiment of the present invention, the user presses the help button to call up the help function on a screen that displays a function name such as “Incoming answer setting” such as the screen 61. A detailed description of “incoming answer setting” is provided on the display unit 9.

  When the help function is called on the screen 61 or the screen 62, the screen 63 is displayed, and a detailed explanation about the incoming answer and a description of the setting method are displayed. The screen 63 describes “Any Key Answer” and “Quick Silent”. The user selects “Any Key Answer” or “Quick Silent” on the screen 63 using the operation unit 8 and presses the enter button. When is pressed, the selected setting can be made. Therefore, if the user wants to set the quick silent after reading the explanation of the incoming answer setting on the screen 63, the user can select the quick silent as shown in the screen 64 and decide without making a return to the setting screen 62. Settings can be made as they are. The screen 65 is a screen indicating that quick silent is set.

  By using the above-described help function for all functions provided in the mobile phone, the user can easily use more functions of the mobile phone.

  The processing operation of the mobile phone according to the flowchart shown in FIG. 2 is realized by causing a computer, which is a CPU (control unit), to read and execute a program stored in a storage medium such as a ROM in advance. Of course you can.
