JP 2006-303666 A JP 2006-31498 A

  Since the UI content changes the display or operation mode according to the system state of the information processing apparatus, the information processing apparatus needs to always grasp the system state in order to operate the UI content. However, if the information processing apparatus inquires about the system state each time UI content is displayed or a page transitions, the display speed of the screen may be significantly reduced.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide an information processing apparatus and a screen display method capable of increasing the display speed or operation speed of a screen.

  An information processing apparatus according to the present invention is an information processing apparatus including a receiving unit that receives an input from a user, and a display unit that displays a screen based on the input received by the receiving unit. Storage means for storing definition information that defines information displayed when in a state, system state acquisition means for acquiring the system state of the information processing apparatus, and information received when an input is received by the reception means Screen generation means for generating a screen to be displayed on the display means based on the definition information stored in the storage means and corresponding to the system state acquired by the system state acquisition means without acquiring the system state of the processing device And.

  The screen display method of the present invention is a screen display method in an information processing apparatus including a receiving unit that receives an input by a user and a display unit that displays a screen based on the input received by the receiving unit, An input is received by a receiving step for storing definition information for defining information displayed when the information processing apparatus is in a predetermined system state, a system state acquisition step for acquiring the system state of the information processing apparatus, and an accepting unit. Screen displayed on the display means based on the definition information stored in the storage step and corresponding to the system state acquired in the system state acquisition step without newly acquiring the system state of the information processing apparatus And a screen generation step for generating.

  According to such an information processing apparatus and screen display method, a screen is generated and displayed based on the definition information corresponding to the acquired system state of the information processing apparatus. At this time, the process of acquiring the system status of the information processing apparatus anew is not performed. In this way, since the screen can be displayed without acquiring the system state of the information processing apparatus each time, the screen display speed or the operation speed can be increased.

  In the information processing apparatus of the present invention, the storage unit corresponds to the first storage unit that stores the definition information and the system state acquired by the system state acquisition unit among the definition information stored in the first storage unit. A second storage unit that stores definition information, and the screen generation unit is based on the definition information stored in the second storage unit while the system state acquired by the system state acquisition unit continues. It is preferable to generate a screen.

  In this case, since the definition information corresponding to the current system state is stored separately from the other definition information, it is not necessary to search for the definition information corresponding to the current system state. Accordingly, the display speed or operation speed of the screen can be increased accordingly.

  In the information processing apparatus of the present invention, it is preferable that the second storage unit and the screen generation unit are controlled by a control module different from the control module that controls the system state acquisition unit.

  In this case, while a certain system state continues, processing for screen display is executed in a control module different from the control module that acquires the system state of the information processing apparatus. As described above, since the processing is completed within one control module without making an inquiry to another control module, the display speed or the operation speed of the screen can be executed at a higher speed.

  According to such an information processing apparatus and screen display method, since the screen is displayed based on the definition information without newly acquiring the system state, the display speed or operation speed of the screen can be increased.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description is omitted.

  First, the configuration of a mobile phone (information processing apparatus) 10 according to the embodiment will be described with reference to FIGS. FIG. 1 is a diagram showing a functional configuration of the mobile phone 10. FIG. 2 is a diagram illustrating a hardware configuration of the mobile phone. FIG. 3 is a diagram showing the relationship between the main system control unit 23 and the UI engine 30 shown in FIG. FIG. 4 shows an example of the attribute table. FIG. 5 is a diagram illustrating a display example of UI content.

  The mobile phone 10 is a mobile communication terminal having a call function, a mail transmission / reception function, and the like, and includes two control modules, a main system 20 that controls an input / output interface and a UI engine 30 that assists screen display processing. The main system 20 includes a key input unit (accepting unit) 21, a first attribute table management unit (first storage unit) 22, a main system control unit 23, and a display unit (display unit) 24 as functional components. Yes. The UI engine 30 includes a UI content control unit 31, a second attribute table management unit (second storage unit) 32, and a UI content drawing unit (image generation unit) 33 as functional components.

  As shown in FIG. 2, the cellular phone 10 includes a CPU 101 that executes an operating system, an application program, and the like, a main storage unit 102 that includes a ROM and a RAM, an auxiliary storage unit 103 that includes a memory, and a mobile communication network. A communication control unit 104 that performs data communication via a network, a display unit 105 that includes a liquid crystal monitor, and an operation unit 106 that includes keys for inputting characters and numbers and executing instructions. Each function described with reference to FIG. 1 reads predetermined software on the CPU 101 and the main storage unit 102 shown in FIG. 2, operates the communication control unit 104 under the control of the CPU 101, and operates the main storage unit 102. Or by reading and writing data in the auxiliary storage unit 103.

  The main system control unit 23 and the UI engine 30 shown in FIG. 1 are middleware that operates on the operating system 40. As shown in FIG. 3, the functions described with reference to FIG. 1 are executed by the main system control unit 23, the UI engine 30 and the operating system 40 performing arithmetic processing while mutually transmitting and receiving data.

  The key input unit 21 is means for receiving a key input by the user of the mobile phone 10. The key input unit 21 outputs the received key input to the main system control unit 23 as a predetermined input signal.

  The first attribute table management unit 22 is means for storing, as an attribute table, definition information that defines UI content (screen) displayed when the mobile phone 10 is in a predetermined system state. The attribute table is information defining a display mode indicating how the menu screen is displayed according to the system state of the mobile phone 10.

  The attribute table is information in which the system state, one or more pages displayed in the system state, and one or more display items included in each page are associated with each other. Therefore, one attribute table corresponds to one system state. The display item includes information on a display mode indicating how the item is displayed on the screen.

  In FIG. 4, as an example, an attribute table T1 (see FIG. 4A) corresponding to the system state “personal data lock state”, and an attribute table T2 (FIG. 4) corresponding to the system state “multi-number service A mode state”. (B)), and an attribute table T3 (see FIG. 4C) corresponding to the system state “personal data lock state and multi-number service A mode state”. “Gray out” in FIG. 4 refers to a state in which an input interface (for example, an icon) is displayed but input through the interface is not possible. On the other hand, “normal display” means a state in which input is possible via the input interface. The contents and configuration of the attribute table are not limited to those shown in FIG. For example, the attribute table may be configured to define information on characters and images themselves displayed on the screen instead of information indicating the screen configuration (menu configuration).

  The first attribute table management unit 22 extracts a specific attribute table in response to a request from the main system control unit 23, and outputs the extracted attribute table to the main system control unit 23.

  The main system control unit 23 is means for controlling the key input unit 21 and the display unit 24 corresponding to an input / output interface. In particular, the main system control unit 23 outputs a signal for displaying the UI content to the UI content control unit 31 based on the input signal input from the key input unit 21. The main system control unit 23 is a functional component realized by deploying and executing a host application that realizes such functions on the CPU 101.

  The main system control unit 23 includes a system state acquisition unit (system state acquisition means) 23a. The system state acquisition unit 23a is a unit that acquires the system state of the mobile phone 10, and more specifically stores the system state and provides the system state to the main system control unit 23 as necessary.

The input signals input to the main system control unit 23 include the following three types.
1. An input signal indicating an operation for changing the display mode (system state) (for example, a signal input when a personal data lock is set)
2. An input signal indicating an operation for starting the UI engine 30 (for example, a signal input when a menu button is pressed)
3. An input signal for generating a page transition when the UI engine 30 is activated (for example, a signal input when a setting menu is selected on the top page and a determination button is pressed).

  When an input signal indicating an operation for changing the display mode is input to the main system control unit 23, the main system control unit 23 instructs the system state acquisition unit 23a to store the changed system state. Based on the command, the system state acquisition unit 23a stores a system state to which the mobile phone 10 is to change. For example, when a personal data lock operation is performed, the system state acquisition unit 23a stores a system state “personal data lock state”.

  When an input signal indicating an operation for starting the UI engine 30 is input to the main system control unit 23, the main system control unit 23 acquires the system state stored in the system state acquisition unit 23a. Subsequently, the main system control unit 23 requests the first attribute table management unit 22 for an attribute table corresponding to the system state. Subsequently, the main system control unit 23 outputs the attribute table input from the first attribute table management unit 22 to the UI content control unit 31 in response to the request. Subsequently, the main system control unit 23 outputs a UI content display instruction for starting the UI engine 30 and displaying the UI content to the UI content control unit 31. This output activates the UI engine 30.

  For example, when an input signal for starting the UI engine 30 is input when the mobile phone 10 is in the personal data lock state, the main system control unit 23 sets the attribute table T1 corresponding to the system state (FIG. )) Is obtained from the first attribute table management unit 22 and output to the UI content control unit 31. Thereafter, the main system control unit 23 outputs a UI content display instruction to the UI content control unit 31.

  The main system control unit 23 not only activates the UI engine 30, but also when an input signal indicating an operation for changing the display mode is input, the attribute table corresponding to the system state after the change. Is output to the UI content control unit 31.

  When an input signal for generating a page transition is input when the UI engine 30 is activated, the main system control unit 23 outputs the input signal to the UI content control unit 31.

  The display unit 24 is a unit that displays a screen (UI content) based on a user operation, and is specifically a liquid crystal screen.

The UI content control unit 31 is means for controlling the second attribute table management unit 32 and the UI content drawing unit 33 based on a signal (data) input from the main system control unit 23. The signal (data) input to the UI content control unit 31 includes the following three types.
1. Attribute table 2. UI content display instruction Input signal to generate page transition

  When the attribute table is input, the UI content control unit 31 outputs the attribute table to the second attribute table management unit 32.

  When a UI content display instruction is input, the UI content control unit 31 requests an attribute table from the second attribute table management unit 32, and the attribute table input from the second attribute table management unit 32 in response to the request. To get. Subsequently, the UI content control unit 31 determines how to display pages and display items by analyzing the contents of the acquired attribute table. Subsequently, the UI content control unit 31 generates a drawing instruction signal for drawing the UI content based on the determination result, and outputs the drawing instruction signal to the UI content drawing unit 33.

  When an input signal for generating a page transition is input, the UI content control unit 31 determines a UI content display method based on the already acquired attribute table, and generates a drawing instruction signal based on the determination result. And output to the UI content rendering unit 33.

  For example, when the UI content control unit 31 acquires the attribute table T1 shown in FIG. 4A when the UI content display instruction is input, the UI content control unit 31 displays the display items “mail”, “ It is determined that “Internet” and “Data BOX” are displayed in gray out and other display items are normally displayed. Thereafter, when an input signal for transition to the setting page is input, the UI content control unit 31 determines the display mode of the setting page based on the acquired attribute table T1.

  The second attribute table management unit 32 is a means for storing, among the attribute tables stored in the first attribute table management unit 22, an attribute table corresponding to the system state acquired by the system state acquisition unit 23a. When the attribute table is input from the UI content control unit 31, the second attribute table management unit 32 stores the attribute table. Thereby, an attribute table corresponding to the system state of the mobile phone 10 is stored in the UI engine 30. In addition, when the attribute table is requested from the UI content control unit 31, the second attribute table management unit 32 reads out the stored attribute table and outputs it to the UI content control unit 31.

  The UI content drawing unit 33 is a unit that generates a screen to be displayed on the display unit 24 based on the attribute table stored in the second attribute table management unit 32. The UI content drawing unit 33 outputs the generated UI content to the display unit 24.

  The UI content drawing unit 33 generates UI content based on the drawing instruction signal from the UI content control unit 31, and this drawing instruction signal is exclusively based on the attribute table stored in the second attribute table management unit 32. Are generated. The attribute table stored in the second attribute table management unit 32 is not updated unless the system state (display mode) changes. Accordingly, the UI content rendering unit 33 does not acquire a new system state for the input received by the key input unit 21 while a certain system state continues, and does not acquire the system state in the second attribute table management unit 32. It can be said that this is means for generating UI content based on the attribute table.

  An example of UI content generated by the UI content drawing unit 33 is shown in FIG. The UI content in FIG. 5A corresponds to the attribute table T1 in FIG. 4A, and icons corresponding to the items “mail”, “Internet”, and “data box” are displayed in gray out. On the other hand, the UI content in FIG. 5B corresponds to the attribute table T2 in FIG. 4B and is displayed so that all icons can be operated.

  Next, the processing of the mobile phone 10 shown in FIG. 1 and the screen display method according to the present embodiment will be described with reference to FIGS. FIG. 6 is a sequence diagram showing processing at the first activation of UI content, and FIG. 7 is a sequence diagram showing processing when the system state is changed. 6 and 7, the first attribute table management unit 22 stores one or more attribute tables in advance (storage step).

  First, it demonstrates using FIG. When the user performs an operation for starting the UI engine 30, for example, an operation for selecting and determining a menu button displayed on the display unit 24 (step S11), the key input unit 21 receives an input signal corresponding to the operation. Is output to the main system control unit 23 (step S12). Subsequently, the system state acquisition unit 23a acquires the system state of the mobile phone 10 (step S13, system state acquisition step), and the main system control unit 23 sets the attribute table corresponding to the system state to the first attribute table management unit 22. (Step S14). Based on this request, the first attribute table management unit 22 reads the attribute table and outputs it to the main system control unit 23 (step S15).

  Subsequently, the main system control unit 23 outputs the acquired attribute table to the UI content control unit 31 (step S16), and the UI content control unit 31 outputs the attribute table to the second attribute table management unit 32 (step S17). ). Subsequently, the second attribute table management unit 32 stores the attribute table (attribute table corresponding to the system state of the mobile phone 10) (step S18).

  Thereafter, the main system control unit 23 outputs a UI content display instruction to the UI content control unit 31 based on the input signal input in step S12 (step S19). Subsequently, the UI content control unit 31 requests an attribute table from the second attribute table management unit 32 (step S20), and the attribute table (mobile phone) input from the second attribute table management unit 32 in response to the request An attribute table corresponding to 10 system states is acquired (step S21).

  Subsequently, the UI content control unit 31 determines a display method based on the acquired attribute table (step S22). Specifically, the UI content control unit 31 determines which part is grayed out and which part is normally displayed based on information on the page, display item, and display mode defined in the attribute table. . Subsequently, the UI content control unit 31 generates a drawing instruction signal based on the determination result, and outputs the drawing instruction signal to the UI content drawing unit 33 (step S23). Subsequently, the UI content drawing unit 33 generates UI content based on the input drawing instruction signal (step S24, screen generation step), and outputs the UI content to the display unit 24. Finally, the display unit 24 displays the generated UI content. This UI content is a screen output in response to the user operation in step S11.

  Thereafter, when the user performs an operation involving page transition, for example, an operation of selecting a setting page on the top page (step S25), the key input unit 21 outputs an input signal to the main system control unit 23 (step S26). The system control unit 23 outputs the input signal to the UI content control unit 31 (step S27).

  Subsequently, the UI content control unit 31 determines a display method based on the attribute table acquired in step S21 (step S28), generates a drawing instruction signal based on the determination result, and sends it to the UI content drawing unit 33. Output (step S29). Subsequently, the UI content drawing unit 33 generates UI content based on the drawing instruction signal (step S30, screen generation step), and outputs the UI content to the display unit 24. Finally, the display unit 24 displays the generated UI content. This UI content is a screen output in response to the user operation in step S25.

  Next, a description will be given with reference to FIG. First, when the user performs an operation for changing the system state (display mode), for example, an operation for setting a personal data lock (step S41), the key input unit 21 sends an input signal corresponding to the operation to the main system control unit. (Step S42). Subsequently, the system state acquisition unit 23 a in the main system control unit 23 stores the system state of the mobile phone 10. The processing of steps S44 to S63 performed thereafter is the same as the processing of steps S11 to S30 in FIG.

  As described above, according to the present embodiment, the UI content can be displayed without acquiring the system state of the mobile phone 10 each time while a certain system state continues. Can be speeded up. That is, by optimizing the timing of acquiring the system state and notifying the UI engine 30 of the system state, the screen display and the screen operation can be speeded up. For example, as shown in FIG. 6, once the attribute table is stored in the second attribute table management unit 32, the page transition is performed without inquiring of the system status to the main system 20 unless the system status (display mode) is changed. (See steps S25 to S30).

  Further, since the attribute table corresponding to the current system state is stored in the second attribute table management unit 32 separately from the other attribute tables, there is no need to search the attribute table corresponding to the current system state. Therefore, the display speed or operation speed of the UI content can be increased accordingly.

  In addition, since the UI content drawing is completed in the UI engine 30 without making an inquiry to the main system 20, the display speed or the operation speed of the UI content can be executed at a higher speed (for example, steps S25 to S30 in FIG. 6 are performed). reference).

  The present invention has been described in detail based on the embodiments. However, the present invention is not limited to the above embodiment. The present invention can be modified in various ways as described below without departing from the scope of the invention.

  In the said embodiment, although the 1st attribute table management part 22 and the 2nd attribute table management part 32 memorize | stored the attribute table, the structure of the memory | storage means which memorize | stores an attribute table is not limited to this. For example, the attribute table storage unit may be configured such that the main system control unit 23 and the UI content control unit 31 access one attribute table management unit.

  In the above embodiment, the mobile phone 10 is used as the information processing apparatus. However, various devices such as a personal digital assistant (PDA) and a desktop computer can be used as the information processing apparatus.
