ABSTRACT:
BACKGROUND OF THE INVENTION
Japanese and other Asian languages are composed of thousands of characters, but only about a hundred keys exist on a typical keyboard. In a computer system adapted for such a language, a word may be input through a combination of phonetic inputs. The user types the sound of the word into the keyboard, the user's inputs are displayed on the screen, and the user requests a front end processor to Ad supply different word choices that sound the same but have different meanings. A system typically displays any one of these thousands of characters on a display screen in a graphical space that typically has a pixel resolution of 16×16 or fewer pixels per character. In such a small space, one character is very hard to distinguish from another.
Field of the Invention
The invention relates to text processing; in particular the invention relates to user input of information for a text processing system in a language having a large number of characters.
SUMMARY OF THE INVENTION
The invention involves displaying a set of characters in a size larger than characters already accepted and displayed in the system. An advantage of such a system is ease of selection among these characters in the set of characters because they are easier to read. Such a system is of a particular advantage in a text processing system that receives a set of user inputs associated with a set of possible characters.
An embodiment of the invention is a method for accepting input in a system. The method includes receiving a set of user inputs associated with a set of characters. Characters from the set of characters are displayed in size larger than characters already accepted and displayed in the system. A user selection of at least a character from the set of characters is received. In response to the user selection, the character is displayed in a size generally corresponding to characters already accepted and displayed by the system.
According to various aspects of the invention, the size larger than characters already accepted and displayed comprises a size generally twice as tall as characters already accepted and displayed by the system, at least one and half as tall as characters already accepted and displayed by the system, or at least twice as large as characters already accepted and displayed by the system. According to other embodiments of the invention, the size larger than characters already accepted and displayed comprises a size appropriate to aid legibility of the character. According to another aspect of the invention, the size larger than characters already accepted and displayed comprises a point value twice as great as the font characters already accepted and displayed. For example, in one embodiment, characters already accepted and displayed are shown in 12 point, and the size larger than characters already accepted and displayed comprises 24 point.
According to one embodiment of the invention, the set of characters comprises kanji. According to another aspect of the invention, the set of inputs comprises a set of hiragana, and the set of characters comprises kanji associated with the hiragana.
According to one embodiment of the invention, more than one character from the set of characters is displayed in response to the user selection.
According to another embodiment of the invention, the set of characters includes a first subset of the set of characters corresponding to the set of user inputs and a second subset of the set of characters corresponding to the set of user inputs. According to another embodiment of the invention, the first subset is displayed in an area having a different background than the second subset. According to another embodiment, the first subset and the second subset are displayed without borders between them.
An embodiment of the invention includes a computer system including a display, a user input device, a memory including a data structure that associates sets of user inputs with respective sets of characters, and computer executable code. The computer executable code receives a set of user inputs, the set of user inputs being received from the user input device. Based on the data structure, the computer executable code determines a set of characters associated with the set of user inputs. The computer executable code causes at least some characters from the set of characters to be displayed on the display. The at least some characters being displayed are displayed in a size taller than the characters already accepted and displayed on the display, thereby providing ease of selection among the at least some characters displayed. In response to a user selection among the at least some characters, the computer executable code causes at least a selected character to be displayed on the display.
An embodiment of the invention is a system including a television monitor, a computer system coupled to a network and to the television monitor, a user input device, and logic. The logic receives a set of user inputs. The set of user inputs is received from the user input device. The logic determines a set of characters associated with the set of user inputs, and causes at least some characters from the set of characters to be displayed on the television monitor. The at least some characters are displayed in a size larger than characters already accepted and displayed on the television monitor, thereby providing ease of selection among the at least some characters displayed. In response to a user selection among the characters from the set displayed, the logic causes at least a selected character to be displayed on the television monitor.
According to an embodiment of the invention, the set of characters comprises characters of an Asian language. According to one example, the set of characters includes Japanese characters. According to another example, the set of characters includes Chinese characters.
