## Background
BACKGROUND
1. Field
The disclosed and claimed concept relates generally to electronic devices and, more particularly, to a method for switching among a plurality of languages that are stored on a handheld electronic device.
2. Description of the Related Art
Numerous types of handheld electronic devices are known. Examples of such handheld devices include, for instance, personal data assistants (PDAs), handheld computers, two-way pagers, cellular telephones, and the like. Many handheld electronic devices also feature wireless communication capability, although many such handheld devices are stand-alone devices that are functional without communication with other devices.
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 email message in French and another in English. However, in order to utilize a handheld electronic device's advance features, such as disambiguation, the user might have to select the language that, for example, corresponds to the language of the original message to which he/she is replying. It would be desirable to meet this need and others in an efficient fashion that makes the handheld electronic device easier to use.

When referring to the phrase “chording actuation” and variations thereof, such designations are meant to cover instances when two or more keys are actuated in succession or simultaneously.
For purposes of the description hereinafter, the terms “upper”, “lower”, “right”, “left”, “vertical”, “horizontal”, “top”, “bottom”, and derivatives thereof shall relate to the disclosed and claimed concept as it is oriented in the figures.
An improved handheld electronic device 2 is indicated generally in FIG. 1 and is depicted schematically in FIG. 2. The exemplary improved handheld electronic device 2 includes a housing 4 upon which are disposed a processor unit that includes an input apparatus 6, an output apparatus 8, a processor 10, and a memory 12. The processor 10 may be, for instance, and without limitation, a microprocessor (μP) and is responsive to inputs from the input apparatus 6 and provides output signals to the output apparatus 8. The processor 10 also interfaces with the memory 12. The processor 10 and the memory 12 together form a processor apparatus.
As can be understood from FIG. 1, the input apparatus 6 includes a keypad 14 and a trackwheel 16. As will be described in greater detail below, the keypad 14 is in the exemplary form of a reduced QWERTY keyboard including a plurality of keys 18 that serve as input members. It is noted, however, that the keypad 14 may be of other configurations, such as an AZERTY keyboard, a QWERTZ keyboard, or other keyboard arrangement, whether presently known or unknown, and either reduced or not reduced.
The system architecture of the improved handheld electronic device 2 advantageously is organized to be operable independent of the specific layout of the keypad 14. Accordingly, the system architecture of the improved handheld electronic device 2 can be employed in conjunction with virtually any keypad layout without requiring any meaningful change in the system architecture. It is further noted that certain features set forth herein are usable on either or both of a reduced keyboard and a non-reduced keyboard.
The keys 18 are located on a front face 20 of the housing 4, and the trackwheel 16 is located at a side 26 of the housing 4. In addition to the keys 18, the trackwheel 16 can serve as another input member since the trackwheel 16 is capable of being rotated, as indicated by arrow 24, and depressed generally toward the housing 4, as indicated by arrow 26. Rotation of the trackwheel 16 provides selection inputs to the processor 10, while depression of the trackwheel 16 provides another selection input to the processor 10.
The output apparatus 8 includes a display 28 upon which can be provided an output 30. An exemplary output 30 on the display 28 is depicted in FIG. 1. The output 30 includes a text component 32 and a variant component 34. As can be seen from FIG. 1, the variant component 34 extends substantially horizontally across the display 28. This, however, is not meant to be limiting since the variant component 34 can also extend across the display 28 substantially vertically or in other fashions. Preferably, the variant component 34 is located generally in the vicinity of the text component 32. The variant component 34 includes a number of outputs 36 from which the user can select. The variant component 34 also includes a selection box 38 that appears in a default position 39. As described in commonly owned U.S. patent application Ser. No. 10/931,281 entitled “Handheld Electronic device with Text Disambiguation,” the outputs 36 are proposed by the text disambiguation function as being the most likely disambiguated interpretation of the ambiguous input provided by the user. The selection box 38 is capable of being moved (i.e. shifted) from the default position 39 to a number of different positions 40 by depressing or actuating the <NEXT> key 42 or by rotating the trackwheel 16. The display 28 also includes a caret (i.e. cursor) 44 that depicts generally where the next output will be displayed.
The memory 12 is depicted schematically in FIG. 2. The memory 12 can be any of a variety of types of internal and/or external storage media such as, without limitation, RAM, ROM, EPROM(s), EEPROM(s), and the like that provide a storage register for data storage such as in the fashion of an internal storage area of a computer, and can be volatile memory or nonvolatile memory. As can be seen from FIG. 2, the memory 12 is in electronic communication with the processor 10. The memory 12 additionally can include one or more routines depicted generally with the numeral 46 for the processing of data. The routines 46 can be in any of a variety of forms such as, without limitation, software, firmware, and the like. As will be explained in greater detail below, the routines 46 include a routine that can be executed to perform a method in accordance with the disclosed and claimed concept as well as other routines that are utilized by the improved handheld electronic device 2.
Additionally, the memory 12 can also store a variety of data sources 48 such as, without limitation, one or more selectable input method languages (i.e. “language” or “languages”) 50 having language objects associated therewith. The input method languages 50 may also have corresponding linguistic sources 52 such as a generic word list or a language rule set. FIG. 2 depicts the memory 12 as containing three input method languages 50. The first input method language 54 can be English, the second input method language 56 can be French, and the third input method language 58 can be Spanish. It is noted, however, that despite FIG. 2 depicting only three input method languages 54, 56, 58 being stored on memory 12, the total number of input method languages 50 that can be stored in the memory 12 is limited only by the memory's 12 capacity. When an input method language 50 is selected, the selected input method language becomes the operative language of the improved handheld electronic device 2. The operative language is the preferred data source for disambiguating ambiguous inputs that are entered into the improved handheld electronic device 2.
Referring to FIG. 3, the languages 50 can be selected from a window 60 that is displayed on the output apparatus 8 upon detection of a predetermined input. The predetermined input can be a chording actuation of at least two input members. For instance, the predetermined input can be a chording actuation of the <ALT> key 62 and the <ENTER> key 64. In another embodiment, the predetermined input can be a press-and-hold actuation of the <ALT> key 62 followed by an actuation of the <ENTER> key 64. In yet another embodiment, the predetermined input can be a press-and-release actuation of the <ALT> key 62 followed by an actuation of the <ENTER> key 64. As can be seen from FIG. 3, the window 60 includes several user-selectable representations 66 of the languages 50 that are available on the improved handheld electronic device 2. The window 60 also includes a selection box 68 that is capable of being moved (i.e. shifted) from the default position 70 to a number of different positions 40 by rotating the trackwheel 16 or by actuating the <NEXT> key 42. A user selects the language that is highlighted in the selection box 68 by either depressing the trackwheel 16 or by actuating the <ENTER> key 64. Upon selection of one of the languages in the window 60, the selected language becomes the operative language of the improved handheld electronic device 2.
In order to prevent the user from unintentionally switching the languages on the improved handheld electronic device 2, a caution window can be displayed that asks the user to confirm whether a language change is desired. The caution window can be displayed immediately after the detection of the predetermined input but prior to displaying the window 60 or the caution window can be displayed after the window 60 has been displayed.
In order to facilitate the entry of text into the improved handheld electronic device 2, the disclosed and claimed concept allows a user of the improved handheld electronic device 2 to rapidly switch between a plurality of languages that are available on the improved handheld electronic device 2. Specifically, the improved handheld electronic device 2 upon detection of a predetermined input will either: switch the operative language to another language wherein the another language is an immediately preceding operative language or switch the operative language to a language that is selected from the window 60. The improved handheld electronic device 2 will switch the operative language to the immediately preceding operative language if the improved handheld electronic device 2 detects a text input, such as an actuation of a key 18 that is assigned to one or more linguistic elements, after the detection of the predetermined input. To illustrate, if the operative language on the improved handheld electronic device 2 is English and the immediately preceding operative language is French, then upon detection of a text input, such as the actuation of the key 18 to which the letter “A” is assigned, the improved handheld electronic device 2 will switch the operative language from English to French. The improved handheld electronic device 2 will switch the current operative language to the language that is ultimately selected from the window 60 if the improved handheld electronic device 2 detects a selection input, such as the rotation of the trackwheel 16 or an actuation of the <NEXT> key 42, after the detection of the predetermined input.
One advantage to the disclosed concept is that the user is able to rapidly switch between languages that are available on the improved handheld electronic device 2 without having to reposition the user's fingers from the keypad because the input members required to execute the predetermined input are located on the keypad.
Another advantage to the disclosed concept is that the user does not have to exit the program in which data is being entered in order to change the operative language on the improved handheld electronic device 2 since the change can be implemented by a simple chording actuation of two or more input members.
Yet another advantage to the disclosed concept is that it reduces the amount of time and the number of keystrokes required to implement a language change since the operative language will automatically switch, after the detection of a predetermined input, to an immediately preceding operative language upon the detection of a text input.
To implement the method, the improved handheld electronic device 2 includes one or more routines 46, stored in memory 12 and executable by the processor 10, for switching between multiple language available on the improved handheld electronic device 2. A flowchart depicting one embodiment of the routine is depicted in FIG. 4.
As can be understood from FIG. 4, the routine begins at step 100, where the improved handheld electronic device 2 detects a predetermined input. In response to the detection of the predetermined input at step 100, the improved handheld electronic device 2 displays, as at step 102, a window 60 having representations 66 of the selectable languages that are available on the improved handheld electronic device 2. The improved handheld electronic device 2 then detects, as at step 104, an input, and determines, as at step 106, whether the input at step 104 is a text input. If the input, at step 104 is a text input, then the improved handheld electronic device 2 switches, as at step 108, the operative language between one of the languages and another language where the another language is an immediately preceding operative language. If the input, at step 104, is not a text input, then the improved handheld electronic device 2 detects, at step 110, a selection of one of the representations 66 of the languages 50 displayed in the window 60. In response to the selection at step 110, the improved handheld electronic device 2 sets, as at step 112, as the operative language the language (i.e. second language) that corresponds to the selected representation.
While specific embodiments of the disclosed and claimed concept have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the disclosed and claimed concept which is to be given the full breadth of the claims appended and any and all equivalents thereof.
