Description:
TECHNICAL FIELD  
       [0001]    The disclosed embodiments relate to methods for providing game dictionaries in a portable apparatus, a rendering application, a portable apparatus comprising a display and means for navigating, and a computer-readable medium having computer-executable components. 
       BACKGROUND OF THE INVENTION  
       [0002]    Communicating via text message services such as short message service (SMS), e-mail, instant messaging, etc., is very popular and plays an increasingly important role in our social life. 
         [0003]    One popular way of communicating these text messages is by using some kind of communication device such as a mobile phone, a PDA, a palmtop computer, a personal computer, a handheld gaming device such as an Playstation Portable (PSP) or the Nokia N-gage, a gaming device such as Xbox, Xbox360, Playstation 3, Wii, etc.. However, entering text messages into these communication devices is often a cumbersome work. While some computing and communication devices, such as personal computers, palmtop computers, and some mobile phones have been equipped with a full QWERTY keyboard for alphanumeric text entry, many other computing, communication, and gaming apparatuses are only equipped with a limited or no keyboard. Text entering using a keyboard with a limited number of keys is often done by pressing a key a varying number of times, generally within a limited period of time, to input a specific letter. This technique is known as multi-tap. However, entering text with multi-tap or with a stylus is quite cumbersome for the user, especially if large quantities of text are going to be entered. Therefore, a number of text entering systems have been developed to facilitate and to speed-up the text entering. These systems, often referred to as single-tap system with predictive text technologies, uses predictive letter patterns to allow the user to enter text by press the keys as few times as possible. 
         [0004]    The predictive text system uses a predictive text dictionary to “intelligently guess” which character(s) or word(s) the user is about to enter. The predictive text dictionary essentially contains a list of character strings, words, acronyms, abbreviations, etc. that is used to predict which word that is being entered by the user. When entering text using multi-tap or single-tap there may be several words that match a given keystroke(character)sequence. The predictive text system may then select the best match(es), i.e. making a priority list of matching words, based on information about word frequency in the used language or word frequency in the users idiolect. 
         [0005]    The electronic gaming industry is growing rapidly and nowadays all kind of people, belonging to both sexes, in all age groups are playing electronic games (hereinafter referred to as games). Modern games are very sociable and are often played in groups consisting of people from around the world. Virtual worlds have been built where people can live an alternative life and make their dreams come true. Many people even meet there future husband or wife through games, so it is no question about it that games are becoming more and more important for a growing number of peoples social life. In most modern multiplayer games communication with other persons, both computer guided and humans, are very important to be able to advance in the game or to achieve some goal such as getting to the next level, finding an artifact, building a house, solving riddles, finding a partner, or just having fun. Most communications in these games are done via text messages as discussed above. To be able to successfully communicate with other players you must be able to use the right vocabulary in your text messages. This is crucial for the users successful integration into a gaming group or a gaming society.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
       [0035]      FIG. 1  shows a mobile communication apparatus  100  comprising a display  102  and means  104  for navigating among items (not shown) displayed in a display area  102 . The navigation means  104  can be a rotating input, a joystick, a touch pad, but can also be implemented using a touch sensitive display, wherein the displayed items directly can be tapped by a user for selection, or be voice activated via a headset or a built-in microphone. 
         [0036]    The mobile communication apparatus can also comprise other elements normally present in such an apparatus, such as a keypad  106 , a speaker  108 , a microphone  110 , a processor (not shown), a memory (not shown), etc. 
         [0037]      FIG. 2  shows a flow chart illustrating a common process of entering text in a communication device, such as a N-gage, Xbox360, and Playstation 3, with a predictive text system  200 . The alphanumerical characters can be entered  202  using a stylus, writing or tapping the characters on the screen or on a dedicated area of the apparatus, or by using all or some of the keys on the communication apparatuses full or limited keyboard. 
         [0038]    The last entered alphanumerical character is compared  212  with a predetermined and/or user configurable end-character such as a for example a ‘space’ character. If the entered  202  alphanumeric character is an end-character  212  the input of that specific character, group of characters, word, phrase, slang, abbreviation, etc. (hereinafter referred to as a word) is complete, and the text entry ends  214 . If the user continues to enter alphanumerical characters after the end-character, i.e. begins to input a new word, the process restarts  201 , else the user have entered all the words to complete a message and terminates the input process. 
         [0039]    If no end-character is detected  212  the character entry is continued and the alphanumeric character, either by itself or in combination with other previous added characters forming a word or a part of a word, are compared in  204  with characters, words, phrases, abbreviations, slang, etc. stored in a predictive text dictionary  206 . If one or several, complete or partial, matches between an entered word(s)  202  and words in the dictionary  206  are detected, they are made available, e.g. displayed on the screen of the communication apparatus as a list of suggestions, to the user  208 . If several matches are found they are displayed in the suggestions list. The user is then able to choose any of the available words from the displayed suggestions list using the navigation means  104  mentioned in conjunction with  FIG. 1 . The character input process is continued  202  regardless of if the user chooses a word from the displayed list or continues to input characters. The input process continuous until an ‘end character’ is detected  212  or the character input is terminated by the user. 
         [0040]      FIG. 3  illustrates an example of a common display view in a handheld communication apparatus  300 , running a predictive text system, comprising a general status indication section  302 , a softkey bar  306  and a general display area  304 . The general status indication section  302  can for example include symbols for battery status, reception quality, speaker on/off, present mode, clock time, etc. The status indication section is not in any way limited to only include these symbols. Thus, other symbols in any shape, form or color can occur. The softkey bar  306 , situated at the bottom of the display view, is operable using the navigation means  104  mentioned in conjunction with  FIG. 1 . The functions of these softkeys are not limited by the functions indicated in the figure. 
         [0041]    The preferred function of the general display area  304 , residing between the status indication section  302  at the top and the softkey bar  306  at the bottom, is to display information from running applications in the handheld communication apparatus. In our case the display area  304  also comprise a scroll bar  308 , a suggestion list  314 , inputted characters  310 , and a cursor  312  showing where next character, word, phrase, abbreviation, etc. can be inputted. 
         [0042]      FIG. 3  shows an example of how a common predictive text system, such as described in  FIG. 2 , operates. A user has entered the characters ‘D’ and ‘e’  310  which together with a cursor  312  is shown at the top of the display views display area  304 . The last entered character is ‘e’ which in this case is not an end-character. The two characters ‘D’ and ‘e’ forms the word ‘De’ which is compared against the words and the letter combinations stored in the predictive text dictionary. Several matches are found and they are displayed to the user in a suggestion list  314 . The displayed suggestions are ‘De’, ° Fe‘, and ‘Dear’ where ‘De’ is rated the most likely word (highest priority) and therefore displayed first in the list. ‘Fe’ is rated second most likely (priority  2 ) and ‘Dear’ rated third most likely (priority  3 ). Since the user in this example wants to enter the word ‘Dear’, the user have to navigated amongst the suggestions down to the suggestion ‘Dear’, indicated by the black cursor bar  316 . The user selects ‘Dear’ by operating ‘Select’ in the soft menu and ‘De’ is replaced by ‘Dear’  318  as shown in the figure. The user can continue to enter characters, for example a ‘s’ to complete the word ‘Dears’ or enter a ‘space’, indicating that the word is complete and a new word is going to be entered, thus restarting the inputting and prediction process as described in conjunction with  FIG. 2 . 
         [0043]    To be able to reduce the problem of communicating amongst gamers in a gaming community the predictive text dictionary must be updatable with special dictionaries connected to a specific game, a specific level in a game, artifacts in a game, call names/signs, events and quests, etc. This will provide the users with a tool for more effectively communicating with each other and strengthening the groups social bonds and thereby enhance the gaming. 
         [0044]      FIG. 4  shows a flow chart illustrating an embodiment comprising a process of entering text in a communication device, such as a mobile phone, with a predictive text system  400 . The alphanumerical characters can be entered  402  using a stylus, writing or tapping the characters on the screen or a dedicated area of the apparatus, or by using all or some of the keys on the communication apparatuses full or limited keyboard. 
         [0045]    The last entered alphanumerical character is compared  404  with a predetermined or user configurable end-character such as for example a ‘space’ character. If the entered  402  alphanumeric character is an end-character  412  the input of that specific character, characters, word, phrase, slang, abbreviation, etc. is completed and the text entry is ended  414 . If the user continues to enter alphanumerical characters after the end-character, i.e. begins to input a new word, the process restarts  401 , else the user have entered all the words to complete a message and terminates the input process. 
         [0046]    If no end-character is detected  412  the character entry is continued and the alphanumeric character, either by itself or in combination with other previous added characters forming a word or a part of a word, are compared in  404  with characters, words, phrases, abbreviations, slang, etc. stored in the predictive text dictionary  406 . 
         [0047]    If one or several, complete or partial, matches between an entered character or word(s)  402  and words in the predictive text dictionary  406  are detected, they are made available, e.g. displayed on the screen of the handheld communication apparatus as a list of suggestions  408 , to the user. Multiple matches are displayed in the suggestions list in a prioritized order with the most likely at the top of the list. Words that are never or seldom used by a user in a gaming environment, words that in a specific gaming context is unlikely to be chosen, and words that in a gaming context is deemed inappropriate words can be made to (user configurable) not appear in the suggestion list  408 , thus making the list considerably shorter. Suggestions displayed in the suggestion list  408  can also be highlighted in different way to signal to the user that the specific suggestion differs in some way from other suggestions. Words can also be prioritized differently depending in what gaming context the user currently is in. These measures will speed-up the selection process considerably since the user does not have to navigate a long suggestions list  418  to find the correct word. Optimally the wanted word is always displayed at the top of the suggestion list. The user is then able to choose any of the available words from the displayed suggestions list using the navigation means  104  mentioned in conjunction with  FIG. 1 . The text input process is continued  402  regardless of if the user chooses a word from the displayed suggestion list  408  or just continues to input new characters  402 . The input process continuous until an ‘end character’ is detected  412  or the text entry is terminated by the user. 
         [0048]    The predictive text dictionary  406  is updatable with special dictionaries  416  depending on the current game and gaming context. New special dictionaries based on the game context can be downloaded by the user or done automatically during or after the game play. The special dictionary can either be added to, replacing, or merged (resulting in the union of both)  416  with the predictive text dictionary currently active. For instance, when a gamer have completed a level in the game a new special dictionary can be downloaded or is uploaded to the user containing new words for communicating with other players. Also, when a group of gamers enters a new level in a game and begins a new quest a special dictionary can be downloaded or is uploaded to the user containing new words connected to the quest (names of heroes, places, artifacts, spells, etc.), which the group will use when communicating with each other. The special dictionary can be downloaded/uploaded using a wireless or wired connection to a gaming server. 
         [0049]    The communication device  500  in  FIG. 5  may have, depending on available storage, one or more dictionaries stored  504  and operating in the devices memory  502  at one time. If the storage size in the device is large, a standard dictionary  503  (hereinafter called a full dictionary) together with several smaller special gaming dictionaries  504  can be stored in the device at the same time. If the storage size is small, a reduced full dictionary or only one or more special dictionaries  504  may be stored at the same time in the device. If the storage size is small it is important that the dictionary in the device is tailored to the user so no unnecessary words (i.e. words never or seldom used by the user) in the dictionaries take up valuable storage space. 
         [0050]    The full dictionary  503  stores a multitude of character combinations and words from every possible subject while a special gaming dictionary focus gaming language used in different games. A special dictionary  504  can for instance be a dictionary with words connected to a specific game, a level in a game a quest, names on heroes and villains in a game, etc.. Special dictionaries can also be customized to comprise words not appropriate for a specific game. A special dictionary can be set to expire at a certain point in time, when the user moves up a level in a game, when the user haven‘t paid for the game any more, when the user changes game, etc.. It can also be set to expire after a certain amount of time, on a specific date, or after running a certain application a specific number of times, or when the memory is full and another dictionary downloaded to the device. This avoids that the dictionary becomes irrelevant. 
         [0051]    As discussed above the internally stored dictionaries  502 , can if wanted, be in constant change depending on the users change in gaming context etc.. To be able to safely store and to migrate the dictionaries to other communication devices the dictionaries can be sent  506  to an external storage (such as a dedicated gaming server) for safekeeping. This will also save precious internal storage  502  in the communication device since not all special gaming dictionaries are needed to be stored internally. 
         [0052]      FIG. 6  shows a display view  600  of an embodiment. A gaming user playing a multiplayer role-playing game on his communication device has just killed a dragon with his gaming friends. The display view  600  shows how the user have entered a text message  602  saying ‘Slaying the Sfalgi dragon brings us one step closer to Er’. Since a special gaming dictionary belonging to the current level in the game he is playing have been automatically uploaded into the device, he gets three suggestions displayed in the suggestions list  604  namely ‘Ervoldin’, ‘Ernhim’, and ‘Erates’. The user can with confidence enter the name ‘Ervoldin’ without making a fool of him self misspelling or remembering the wrong name. 
         [0053]    A system architecture for managing a system  700  according to an embodiment is shown in  FIG. 7 . A Home Location Register (HLR)  702  contains a database (not shown) including relevant subscriber information for provision of telecommunication service. A International Telecommunication Union (ITU) specified network  704  interconnects the individual parts of the system  700 . A category gateway  706  is a switching unit routing a requested category to a mobile communication apparatus  708 - 712 . A Category Service Center  714  (DSC) and the category gateway  706  handle and routes the categories between the DSC  714  and the network  704 . From the network  704 , the categories are routed to the handheld communication devices  708 - 712  via a Mobile Switching Center (MSC)  716  to a Base Station Controller (BSC)  717  and a Base Transceiver Station (BTS)  720 ,  721 , or a Radio Network Controller (RNC)  718  and a Node B  722 . Alternatively, the categories are routed to the handheld communication devices  708 - 712  via a Serving GPRS Support Node (SGSN)  726 ,  728  to the BSC  717  and the BTS  720 ,  721 , or the RNC  718  and the Node B  722 , respectively. The BTS  720 ,  721  or the Node B  722  establish the air connection to the handheld communication devices  708 - 712 . 
         [0054]    According to an embodiment, a network operator or other third party company, for example the provider of the application, handling a category server  724  could offer a category service function where dictionaries associated with certain applications can be purchased. For example a network operator may have a dictionary server  724  supporting a feature where the user may send a category request from his handheld communication devices  708 - 712  to the category server  724  upon using a certain application of the handheld communication devices, e.g. a gaming or messaging application. 
         [0055]    The invention can be computer-implemented, i.e. the media handling is performed on a general or dedicated computerized apparatus  801 , such as a personal computer, a mobile phone, a digital camera, a personal digital assistant, a media player, or other similar apparatus. Instructions for performing the invention can then be executed by the apparatus. These instructions can be loaded into the apparatus  801  from a computer-readable medium  802 , as exemplary illustrated in  FIG. 8 , having a data structure stored. The data structure comprises the control instructions, which upon execution causes the apparatus to perform any of the disclosed embodiments as described above. 
         [0056]      FIG. 9  illustrates a user interface (UI)  901  in a portable apparatus having an input interface  902 , which as described in above embodiments can be actuated by a user, and a display interface  904  for displaying information to the user as described in the above embodiments. 
         [0057]    While the disclosed embodiments have been described with specificity to handheld communication devices, other types of computing devices with which the embodiments can be used will occur to those skilled in the art. For example, a personal computer can benefit from the invention in the same manner as the handheld communication device.
