specific Embodiment approach

[0068]The present invention provides a method for handwriting input on a portable terminal. At least one sensing unit is arranged in the keyboard area of ​​the portable terminal to form a sensing surface; and the sensing unit is coupled with a plurality of keys of the portable terminal keyboard; The sensing unit circuit is coupled with the keyboard circuit of the portable terminal. The mechanical component of the induction unit is coupled with a plurality of key mechanical components of the keyboard of the portable terminal. And described induction unit and portable terminal keyboard circuit are all coupled with the microprocessor of portable terminal; When carrying out text input, adopt an induction object to write the text to be input on described induction surface, thereby make described induction The motion trajectory of the object generates two-dimensional coordinate data through the sensing unit;

[0069] The microprocessor of the portable terminal processes the two-dim...

Abstract

At least one induction unit setup at terminal keypad area forms an induction face. Part of information of character to be input is written on the induction face through an inductor. Motion locus of the inductor through the induction unit generates multi dimensional coordinate data. Processing the said multi dimensional coordinate data, microprocessor in portable terminal generates at least one candidate character. At least one character among the candidate characters is displayed on region of candidate character. The character to be input selected from the candidate characters through specific key or key combination is displayed on screen.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an electronic handwriting input method and device, specifically a method and system for handwriting input on a portable terminal. Background technique [0002] With the development of communication technologies, portable terminals have become popular communication tools. Portable terminals are developing toward miniaturization, humanization, diversification and digitalization along with the needs of users. Such as mobile phones, more and more portable terminal users start to use mobile phone text communication methods such as email (Email), multimedia message (MMS), instant message (IM) and short message (SMS), and input text on it especially It is very difficult to input non-alphabetic characters like Chinese, and with the continuous miniaturization of mobile phones, users will be slower and slower to input characters such as Chinese characters and English letters o...
