Abstract
A character input system for a limited keyboard, in which a number of input keys in the keyboard is smaller than a number of characters in an input alphabet, the system comprising: a memory comprising a plurality of different mappings of said characters onto combinations of said keys; and a selector for allowing a user to select one of said mappings for character input. The different mappings are optimized for different users and different purposes, so that the user may select a mapping for simplicity of use, or one optimized for touch-typing, or for minimal key pressing or for minimal ambiguity or for other factors and combinations thereof.
Claims25
A character input system for a limited keyboard, in which a number of input keys in the keyboard is smaller than a number of characters in an input alphabet, the system comprising:
- a memory comprising a plurality of different mappings of said characters onto combinations of said keys;
- and
- a selector for allowing a user to select one of said mappings for character input.
A character mapping method for a limited keyboard, in which a number of input keys in the keyboard is smaller than a number of characters in an input alphabet, the method comprising:
- mapping said characters in at least two different ways to keys on said keyboard, to provide at least two different keyboard mappings;
- and
- allowing a user to select one of said keyboard mappings for character input at said limited keyboard.
A method of providing a keyboard based on mapping a first number of characters onto a keyboard having a second number of keys, wherein the first number is larger than the second number, the method comprising:
- analyzing a language usage database for usage statistics;
- applying said characters in at least two ways onto said keyboard to form at least two mappings;
- providing a score to said mapping based on said usage statistics applied to said keyboard;
- and
- selecting between said languages for use based on said score.
