  FIG. 2 is a schematic diagram showing the components of the mobile device 101. The components of the mobile device 101 include an earphone 103, a microphone 104, and a touch screen display 105. The mobile device 101 also includes a system bus 107 that allows the components to be connected thereto and allow the components to communicate with each other. Here, the components are shown to communicate via a single system bus 107. In practice, however, a mobile device may include multiple buses to connect various components. The device also includes an application processor 108, a baseband processor 109, a memory 110, an earphone controller 111, a microphone controller 112, and a touch screen display controller 113. The application processor 108 is for operating an operating system and user applications. The baseband processor 109 is for controlling the telephone stack. Device 101 also includes a cell phone radio 114 coupled to antenna 115. The mobile device 101 is configured to communicate via a radio 115 with a base station of a mobile phone network (not shown). The mobile device 101 also includes a storage device controller 116 that is connected to a storage device 117, which may be a removable storage device such as an internal hard drive or a flash memory card.

  This description of the components of the mobile device is an example of how the components may be configured. Many variations may include different components and different configurations of those components. The invention is not limited to any particular set of components or any particular combination of those components. As computer device technology advances, certain components may be replaced by other devices that perform the same function. Such a device can also embody the present invention.

  Mobile device 101 includes an operating system (OS) that is stored in a read only memory (ROM) portion of memory 110. The OS may be a Symbian OS. The device also includes other software applications that may be stored in ROM or stored in storage device 117. The application processor 108 is configured to execute OS and application instructions. Execution of these instructions causes the mobile device 101 to perform certain functions by controlling various hardware components of the device.

  FIG. 3 is a functional diagram showing a logical link between the software of the device 101 and hardware components. The operating system 201 includes a kernel 202 and a middleware section 203. The kernel 202 is configured to manage the hardware resources of the mobile device 101 and the communication between the hardware and software stored on the device. The middleware 203 controls communication between an application running on the device and system resources. Mobile device 101 has a number of applications 204 stored in memory 110 or storage device 117. These applications 204 may be part of the operating system 201 or may be third party applications. Each of the applications may access computing resources through the middleware section 203. FIG. 3 also shows hardware 205.

  FIG. 4 is a further functional diagram showing logical links between the software and hardware components of device 101. FIG. 4 shows a touch screen display 105 coupled to the touch screen display controller 113. The controller 113 is coupled to a device driver 301 that may be provided as a software component of the operating system 201. OS 201 also includes an input server 302 for processing input from the touch screen display 105. Input server 302 is adapted to communicate with device driver 301. OS 201 also includes a window server 303 that controls access to display 105 by OS 201 and other applications. For example, the drawing may be clipped to the application's visible window. The window server 303 presents an interface to each client application.

  OS 201 also includes a text module 305. The text module 304 is adapted to translate the input signal from the input server 302 to determine what characters or numbers the user has entered. The text module 304 also determines what to display on the display 105 based on user input. For example, if the user is pressing the touch screen display 105 to enter a message, the text module 304 determines what characters the user has entered and causes those characters to be displayed on the touch screen display 105. The text module 304 communicates with the window server via a window server (WS) interface 305. Mobile device 101 also includes a character store 306. The character store 306 is for storing a character system according to a specific alphabet. The character store 306 is also used to store words that are available for a specific language for text prediction purposes. In this case, the store contains English words. Text module 304 may also be adapted to perform predictive writing functions.

  The text module 304 is adapted to display various keypad representations on the touch screen display 105 to allow a user to enter information into the device. One representation may be a QWERTY type keypad. Another representation may be a 12-key mobile phone type keypad. An example of such a representation is shown in FIG. FIG. 5 shows the mobile device 101 showing a 12-key keypad representation 401 on the display 105. Device 101 also shows a search box 402, which is an area for displaying text entered by the user. As can be seen, the text module 304 is configured to display characters on each key representation. The 12-key keypad representation 401 includes the numbers 0-9 and * and #. Each numeric key also serves as an input for alphabetic characters. In FIG. 5, numeric keys represent alphabetic characters in the following manner. 2: A-B-C, 3: D-E-F, 4: G-H-I, 5: J-K-L, 6: M-N-O, 7: P-Q-R-S, 8: T-U-V, 9: W-X-Y-Z.

  The mobile device 101 is configured to provide at least two modes of text input. Initially, the user may enter a character by tapping the required key expression and selecting the required character. For example, to select “A”, tap the 2 key once. To select “B”, tap the 2 key twice. The text module 305 is then adapted to implement predictive text input such as T9. Predictive text allows the user to press a key representing the required character only once. Based on the character of the key pressed, the text module 304 determines what possible characters can be formed based on the characters stored in the character store 306. The word options are then displayed via the window server 303, either automatically or in response to a user action. For example, when the user wants to input the word “based”, the user may press the keys in the order of 2-2-7-3-3. Display 105 shows the word “based”. In addition, the text module 304 shows other words on the display 105 that may be created by their key order. The user may press a key expression (eg, * key expression) to show other words (in this case, the words “cared” and “bared”). The order in which the words are listed can be in alphabetical order or based on a usage frequency indicator.

  Text input can be used in various states. For example, text input can be used when writing an email or text message. Alternatively, text input can be used when retrieving a set of data. For example, the mobile device 101 may include an address book that includes a database of contacts. In the present embodiment, the mobile device 101 includes an address book 307 and a contact database 308. The address book communicates with the window server 303 via the WS interface 309. The contacts may be displayed as a list on the device display 105. The user can search for a contact by typing the first few letters of the contact name. For example, if the list contains only entries for Hogg and Hook that begin with “H”, entering “H” removes other contact entries from the view, leaving only Hogg and Hook. Entering “O” will not narrow the list any further. Entering "G" removes the hook and leaves Hogg as the only contact that begins with H-O-G. One way to enter the search string in this case is to use predicted characters using a 12-key keypad representation. The user then only has to press the required key once to select a particular character. If the contact list contains Hogg and Hook but does not contain any entries that begin with "G" and "I", the user simply presses the 4 key once and the list starts with "H" Limited to two entries. The user may then press 6 followed by 4 to select O and G, only Hogg is shown.

  This description of the software modules shown in FIG. 4 is one example of the manner in which the components can be configured. Many variations can include different modules and different configurations of those modules. The present invention is not limited to any particular set of modules or any particular combination of those modules. As software advances, there may be certain modules that are replaced by other software that performs the same function. Devices including such modules can also embody the present invention.

  The text module 304 is also configured to provide feedback to the user via the display 105 regarding strings that may be entered. This is accomplished by graying out any characters that do not represent valid input. The process used to implement this mechanism is described with respect to FIG. Device 101 stores a number of contacts in contact database 308 as described above. The user may read the address book 307 by selecting an address book application from the menu of the user interface of the device 101. When the user loads the address book 307, the entire list of contacts in the address book is displayed as a scrollable list (block 501). The text module 304 determines which character is used as the first character of the contact. All unused characters are displayed in gray (block 502). The user may then press any key expression that has non-grayed characters on it (block 503). If a key expression without a highlighted character is pressed, no input is made. In the example shown in FIG. 6, the user is pressing key 4 and the text module displays only two contacts, starting with either "G", "H", or "I". Yes. In this case, Hogg and Hook are the only contacts that begin with “G”, “H”, or “I”. “H” is displayed in the search box 402 (block 504) and the entries Hogg and Hook are shown in the list (block 505). The process then repeats itself. The letter “O” is shown in black and all other letters are grayed out (block 502). The first “H” in Hogg and Hook is underlined. The only key expression that may be pressed to provide input is 6 keys. If the user then presses 6 (block 503), “O” is displayed in the search box 402 after “H” (block 504), and the letters “O” and “G” are black. Indicated. All other keys are grayed out (block 502), as shown in FIG. At each iteration, after block 505, the user may select and enter from a sub-list (block 506).

  This mechanism may also be used with predictive text input when a user writes an email or text message. In this case, since there are words that start with all alphabetic characters, no characters are initially grayed out. However, as the user writes words, the number of available words decreases and the characters that can be entered also decrease. Accordingly, characters that cannot be used are displayed in gray.

  In another embodiment of the present invention, the mobile device 101 is adapted to provide linguistic predictive text using at least two scripts. In one embodiment, the character store 306 includes at least two different scripts. In this example, the character store 306 includes the Latin script system used for English and the Devanagari script system used for Hindi. The text module is configured to display a 12-key keypad representation on the touch screen display 105 as shown in FIG. Each key represents a Latin script and a Devanagari script (as described above in connection with FIG. 5). Both character sets are shown on the keypad, as shown in FIG.

  Text module 304 is adapted to provide predictive writing for both Latin and Devanagari scripts. In this example, the text module 305 automatically determines whether the user is writing in English or Hindi and predicts the word accordingly. The process used to implement this mechanism is described with respect to FIG.

を表す。アドレス帳がこれらの文字のうちの1つで始まるエントリだけしか含まない場合は、それらのエントリが示され、最初の文字が検索ボックス402の中に表示される。代替として、エントリが、1つを超える文字に対して存在してもよい。この場合、エントリは、アルファベット順、および文字体系の順序に示される。例えば、エントリは、J-L、そして

の順序で示されてもよい。他の順序が可能である。 Device 101 includes an address book 307 that may be searched in the same manner as described in the previous embodiments. When the user first loads the address book 307, the entire list of contacts is displayed as a scrollable list (block 601). In this embodiment, address book 307 includes a number of contacts, some in Hindi and some in English. The user can then enter the first character by pressing the key expression (block 602). Text module 304 then determines which contact corresponds to the character associated with the key (block 603). There may be no contact matches, in which case the text module 304 provides feedback to this result to the user (block 604). This may be in the form of an audio or visual alert (block 605). In another case, the text module 304 detects a contact match (block 606). This may be a single character. One or more entries may exist for that single character. For example, the user may select the 5 key, which is the Latin script J, K, and L, and the Devanagari script.

Represents. If the address book contains only entries starting with one of these characters, those entries are shown and the first character is displayed in the search box 402. Alternatively, an entry may exist for more than one character. In this case, the entries are shown in alphabetical order and alphabetical order. For example, the entry is JL, and

May be shown in the order of: Other orders are possible.

  If the text module 304 finds one or more entries corresponding to the characters associated with the pressed key expression, those entries are shown as a scrollable list and the characters are displayed in the search box 402. Displayed (block 607). At this point, the user may select an entry from the sublist (block 608). Alternatively, the user presses more key expressions and the process repeats by returning to block 602. The process may then be repeated until the desired entry is displayed.

The text module 304 automatically determines which entry contains one of those characters as the first character of the contact. FIG. 11 shows the display after the 5, 2, and 5 keys are pressed. The only entries in the contact list that correspond to this keystroke sequence are "Jake" and

It is. Text module 304 has "Jake" and

Indicates a contact entry for.

  This dual script system can be extended to predictive text when writing messages such as email or text. The text module determines which words can be made from the Latin script system and from the Devanagari script system, as described above, and displays the available words. If a word from only one script is available, that word is shown. When a word from one script is selected, the text module 304 becomes the default for that script. The following words are written in that same script, assuming words from that script are possible. If no words from that script are available, the device assumes that there is a word corresponding to the input string and displays words from other scripts.

  In a further embodiment of the present invention, the option of graying out characters can be combined with the use of a dual script system. FIG. 11 shows the device 101 from the previous embodiment, where available characters are black and unavailable characters are grayed out.
