Single finger input system specific for handheld terminals

Abstract

The present invention relates to a single-finger input method dedicated to a handheld terminal, comprising the following steps: 1) data collection, through a small data collector fixed or externally connected to the handheld terminal, collecting continuous trajectory data when the finger slides over the surface; 2) software identification, identify its corresponding Chinese input strokes according to the collected data; 3) code comparison, obtain its Chinese character code according to the identified Chinese input strokes; 4) text output, output its corresponding Chinese character code according to the obtained Chinese character code Chinese characters. The data collector may be a trackball or a photoelectric data collector. The data collector can be integrated in a handheld terminal, and the external connection can be a data collection line or a wireless connection. The invention provides a single-finger input method specially used for a hand-held terminal, which can conveniently and intuitively input Chinese characters with only one finger and one key surface.

Description

【Technical field】 [0001] The present invention relates to an input method of a handheld terminal, in particular to a single-finger input method specially used for a handheld terminal. 【Background technique】 [0002] At present, mobile phones, PDAs and other portable and handheld terminal devices on the market mainly use four input methods: 1. Terminal keyboard input method; 2. Terminal touch screen input method; 3. Key combination input method; 4. External small keyboard Input. Although the above-mentioned various input methods have been relatively perfect, and each has its own uniqueness in technology, and has overcome some deficiencies. But it is not perfect enough, and there are still bottlenecks that limit its rapid input data: [0003] 1. Number keypad input method: This method has a large number of application examples on various mobile phones. Enter via the keypad integrated on the device. The Chinese aspect also utilizes this number keypad to check Chinese charac...

AI Technical Summary

Problems solved by technology

This keyboard input method has the following disadvantages: the handheld device cannot be made very large, and the keyboard is too small to be easy to operate

Touch screen handwriting input has the following disadvantages: this method is greatly affected by vibration, and it is almost impossible to input in the car; at the same time, this input method will cause greater wear and tear on the touch screen; after a period of time, the screen will be scratched

The input method of function keys has the following shortcomings: this method cannot be used for intuitive input, and the content represented by the function keys in all directions needs to be preset; in the input of Chinese characters, a standard of input method must be announced uniformly before it can be used. implement

There are the following disadvantages in the way of external keyboard input: this method needs to carry a small keyboard on the body, which is inconvenient to carry; in addition, it is difficult to complete the input with the small keyboard in places with large vibrations
