The disclosed embodiments generally relates to the display of the language in use in character input applications such as text editors and more particularly to the display of character format mode.
Handheld electronic devices are used in a variety of language settings and users can often find themselves writing text in multiple languages. For example, a user might reply to one e-mail message in English and to another in Finnish. At the same time the user switch frequently between different character format modes, for example, upper-case character format, lower-case character format, automatic switching between the two former modes, e.g. input of upper-case character format after punctuation mark only in automatic capitalization format mode, or text disambiguation mode. It is therefore advantageous to display both the input language and character format mode on the user interface for the user to get immediate feedback on the current input mode.
Previously the currently selected input language and character format mode are presented as separate indicators on the user interface. The current choice of input language may be indicated as a visual abbrevation indicator and another visual indicator may present information regarding other aspects of the current input mode, such whether a reduced-sized keyboard is currently in a lower-case letter entry mode or an upper-case letter entry mode. The indicators may be positioned towards the corner of the display and be of reduced size in order to minimize its obstruction of other user interface items.
A drawback with the previously known techniques is the increased gathering of information on the limited display area, as the density of useful information on the display must be improved to achieve a sufficient overview of the message text and provide space for additional status information and applications on the display of a handheld electronic apparatus, such as a mobile communication terminal. A further disadvantage from related art solutions is the reduced legibility following the efforts to minimize the size of obstructive display elements.
In view of the above, it would be desirable to achieve a method for indicating the current input language and character format mode on a display of an electronic apparatus.
It would also be desirable to achieve an electronic apparatus for indicating the current input language and character format mode on the display of the electronic apparatus.
It would also be desirable to achieve a user interface for indicating the current input language and character format mode on a display of an electronic apparatus.
It would also be desirable to achieve a computer program product for indicating the current input language and character format mode on a display of an electronic apparatus.
According to a first aspect of the disclosed embodiments there has been provided a method for indicating an input language on a display of an electronic apparatus comprising;
displaying an input indicator on the display, the input indicator being associated with a character input application,
providing the character input application access to a plurality of input languages each language having an associated language code, the language code comprises a sequence of characters,
displaying by means of the input indicator the sequence of characters identifying the language code for the input language accessed by the character input application,
associating one of a plurality of predetermined representations of characters in the sequence of characters with the input of one of a plurality of character format modes of the input language in the character input application, such that the one of a plurality of character format modes of the input language is indicated by the language code displayed by means of the input indicator. By associating a predetermined representation of the characters in the language code with a character format mode it is possible to get feed-back on the current character format mode used directly from the language code indicator. Accordingly, no separate indicator for the character format mode is necessary. This optimizes the use of available space on the display. Further, it is not required by the user to move focus between several indicators, as the most necessary information regarding the current input mode, i.e the character format mode and the input language, is available at the same location.
According to one embodiment the association of one of a plurality of predetermined representations of characters in the sequence of characters may involve displaying characters in the sequence of characters as upper-case, lower-case, underlined, bold, italic or any combination thereof such that the display of any first character may be different from the display of any second character in the sequence of characters. By displaying the characters in the language code in several different formats, i.e. predetermined representations, several different character format modes can be identified by the user, in that each predetermined representation is associated with a character format mode.
According to another embodiment the association of one of a plurality of predetermined representations of characters in the sequence of characters may involve;
displaying at least one character in the sequence of characters as upper-case for input of an upper-case character format mode in the character input application;
displaying at least one character in the sequence of characters as lower-case for input of a lower-case character format mode in the character input application;
displaying at least one character in the sequence of characters as upper-case and displaying at least one character in the sequence of characters as lower-case for input of upper-case character format mode after punctuation mark and input of lower-case character format mode after initial said upper-case character format mode input in the character input application,
displaying at least one character in the sequence of characters as upper-case, lower-case, underlined, bold, italic or any combination thereof for input of disambiguation character format mode in the character input application. The input of lower-case character format mode after an initial upper-case character format mode input in the character input application is known as automatic capitalization, i.e. an upper-case character following a punctuation mark and a lower-case character following this initial upper-case character. Several possible combinations may be used for the representation of a disambiguation mode, such as T9 text disambiguation or any other text disambiguation logic. Further, other representations of characters in the language code can be associated with other character format modes, for example, bold characters in the language code may be associated with input of bold characters in the character input application, italic representation of the characters in the language code may be associated with input of italic characters in the character input application, underlined characters in the language code may be associated with input of underlined characters in the character input application. Displaying the characters in the language code as a particular font type may be associated with the input of a character format mode where the characters in the character input application has the corresponding font type. Displaying the characters in the language code in a particular color may be associated with the input of a character format mode where the characters in the character input application has the corresponding color.
According to another embodiment the language code may be displayed as a sequence of at least two characters in the sequence of characters. Several different variations are possible regarding the number of characters in the language code. A shorter sequence of characters may be advantageous in order to save space. The characters in the sequence of characters may be any alpha-numerical character.
According to another embodiment there is provided input to the character input application is by means of an input device, the input provides a first selection and a second selection of a plurality of selections, associating the first selection with the one of a plurality of input languages and associating the second selection with the one of a plurality of predetermined representations of characters. The input from the input device may accordingly determine input language and character format mode. The input of a special character, that may be defined by the user, in the character input application may also automatically switch to another input language and/or to another character format mode. Likewise, depending on the contextual circumstances, the character input application may also automatically switch to another input language, for example, if a message text is received in Finnish and if a subsequent reply is made, the input language may switch from a current English setting to a Finnish setting when choosing the reply function in the character input application. The change of language may also occur automatically depending on the origin of the message, for example, the country code of the phone number of the sender of the message. The language may also be changed by holding a key while pressing any alpha-numerical key, for example the ‘def’ key in case of a ITU-T keypad, to present a selection menu of input languages, for example, starting with the letter “e” after pressing the alpha-numerical key ‘def’ two times.
According to a another embodiment the character input application may be associated with a text editor, e-mail program, messaging program, or any program receiving character input. The input indicator, displaying the language code and one of a plurality associated character format modes may accordingly be utilized for any character input application.
According to a another embodiment the input language is the language used for text disambiguation in input of a disambiguation character format mode in the character input application. This is advantageous in that a user may quickly identify by means of the input indicator the current language used for text disambiguation.

In addition, but not shown in
The internal component, software and protocol structure of a mobile communication terminal 200/300 according to one embodiment, will now be described with reference to
The mobile communication terminal has a controller 531 which is responsible for the overall operation of the mobile communication terminal and is preferably implemented by any commercially available CPU (“Central Processing Unit”), DSP (“Digital Signal Processor”) or any other electronic programmable logic device. The controller 531 has associated electronic memory 532 such as RAM memory, ROM memory, EEPROM memory, flash memory, hard drive, optical storage or any combination thereof. The memory 532 is used for various purposes by the controller 531, one of them being for storing data and program instructions for various software in the mobile communication terminal. The data may include a plurality of input languages, which are accessible to a character input application 540.
The software includes a real-time operating system 536, drivers for a man-machine interface (MMI) 539, an application handler 538 as well as various applications.
The applications include aforethe character input application 540, as well as various other applications 541/542, such as a contacts (phonebook) application, a messaging application, a calendar application, applications for voice calling, video calling, speech recognition, web browsing, media player, document reading and/or document editing, a camera application, one or more video games, a notepad application etc.

The software also includes various modules, protocol stacks, drivers, etc., which are commonly designated as 537 and which provide communication services (such as transport, network and connectivity) for an RF interface 533, and optionally a Bluetooth interface 534 and/or an IrDA interface 535 for local connectivity. The RF interface 533 comprises an internal or external antenna as well as appropriate radio circuitry for establishing and maintaining a wireless link to a base station (e.g., the link 102 and base station 104 in
The mobile communication terminal also has a SIM card 530 and an associated reader. As is commonly known, the SIM card 530 comprises a processor as well as local work and data memory.
The display 600 has an input indicator 601 which is associated with the character input application 602. The input indicator 601 will accordingly reflect the status of the character input application 602 and the input as described below. The input to the character input application 602 is provided by the input device 524. For example, a touch sensitive display 303 may be used for input of characters to the character input application 602 in
The controller 531 associates one of a plurality of predetermined representations of characters 606 in the sequence of characters 605 with the input of one of a plurality of character format modes 607 of the input language 603 in the character input application 602. Thus for a current language code 604 having a particular sequence of characters 605 several predetermined representations 606 may be available, in that the characters are represented in a plurality of ways, while the order between the characters in the sequence of characters 605 is maintained. Each representation is associated with a character format mode 607 of the input language 603. A plurality of character format modes 607 of the current input language 603 are accordingly achieved by the plurality of predetermined representations of characters 606 in the sequence of characters 605. The input indicator 601 displays the sequence of characters 605 identifying the language code 604. The input indicator 601 displays accordingly a plurality of predetermined representations of characters 606 in the sequence of characters 605, each predetermined representation 606 being associated with the input of one of a plurality of character format modes 607. The one of a plurality of character format modes 607 is accordingly being indicated by the language code 604 displayed by means of the input indicator 601.
Predetermined should in this context be construed as each representation of characters 606 in the sequence of characters 605 has an associated character format mode 607 of the current input language 603, in that the character format mode 607 for each representation characters 606 in the sequence of characters 605 is known.
The plurality of predetermined representations of characters 606 in the sequence of characters 605 may involve the display of characters in the sequence as upper-case, lower-case, underlined, bold, italic, or any other character representation, or any combination thereof, such that the display of any first character in the sequence of characters 605 may be different from the display of any second character in the sequence of characters 605.
For example, for a language code 604 “eng” for a current English input language 603 in the character input application 602, the different representations of characters 606 in the sequence of characters 605 “eng”, may accordingly be displayed as; “eng”, “Eng”, “ENG”, “Eng”, “eng”, “eng”, “Eng”, “Eng”, or any other combination of character representations 606. Each of these previous examples of representations of characters 606 in the sequence of characters 605 are associated with a corresponding character format mode 607 of the current input language 603. For example, the display of at least one character in the sequence of characters 605 as upper-case may be associated with input of an upper-case character format mode 607 in the character input application 602. For the upper-case character format mode 607 the character input application 602 generates upper-case characters in response to input from an input device 524, such as a set of keys 204/304, a multi-way input device 210, a touch screen display 303, a microphone 205/305 or any other input device capable of providing input to a character input application 602. Further, the display of at least one character in the sequence of characters 605 as lower-case may be associated with input of a lower-case character format mode 607 in the character input application 602. The display of at least one character in the sequence of characters 605 as upper-case together with the display of at least one character in the sequence of characters 605 as lower-case may be associated with the input of an upper-case character format mode 607 after punctuation mark and input of lower-case character format mode 607 after the initial input of an upper-case character in the character input application 602, commonly known as automatic character capitalization after punctuation mark, referred to as auto-capitalization character format mode 607. Several other character format modes 607 may be associated with the plurality of predetermined representations of characters 606. For instance, the use of text disambiguation, such as T9 logic, referred to as disambiguation character format mode 607 or T9 character format mode 607, may be associated with the display of at least one character in the sequence of characters 605 as underlined, bold, italic or any other predetermined representation of characters 606. In case no input language 603 is selected, the input indicator 601 may display an arbitrary sequence of character 605, such as “abc”. In one embodiment, the sequence of characters 605 identifying the language code 604 may only be displayed by the input indicator if the disambiguation logic is used, that is, if the disambiguation character format mode is active. If the disambiguation logic is not used an arbitrary sequence of character 605, such as “abc” may be displayed by the input indicator 601. Likewise, the display of the language code 604 may be associated with the disambiguation character format mode 607, such that the input language 603, associated with the language code 604, is the current language the disambiguation logic uses for text disambiguation.
Table 1 show two examples of input languages, English (1) and Finnish (2) among a plurality of input languages (N), and the associated language codes Eng (1.1), En (1.2), and Fin (2.1), Fi (2.2) among a plurality of languages codes (1.M) and (2.M), respectively. The sequence of characters in the language code Fin (2.1), as an example, has the predetermined representations of characters FIN (2.1.1), fin (2.1.2), Fin (2.1.3), and Fin (2.1.4), among a plurality of predetermined representations of characters (2.1.X), each of which are associated with a character format mode, for example, FIN (2.1.1) being associated with an upper-case character format mode in the character input application.
