Method and equipment for touch input

Abstract

The invention provides a method and equipment for touch input, comprising a touch screen, a detecting unit, a direction calculating unit, a searching unit and a display unit, wherein the touch screen is used for carrying out touch input action; the touch input action comprises the steps: contacting with the touch screen, leading a touch point to move by a distance along a first direction, then stopping at the moved position, then leading the touch point to move continuously by a distance along a second direction, and then separating with the touch screen; the detecting unit is used for detecting all the positions of a user contacted with the touch screen at any time; the direction calculating unit is used for calculating the first direction, the stopping and the second direction containedin the touch input action on the basis of detecting results; the searching unit is used for searching corresponding characters in a character table on the basis of the first direction and the second direction; and the display unit is used for displaying the characters searched by the searching unit.

Description

technical field [0001] The present invention relates to a method and device for touch input, in particular to a method and device for determining input characters based on the direction of touch movement. Background technique [0002] In recent years, with the development of signal processing technology and display technology, the application of various information processing terminals is very common. In information processing terminals such as mobile communication terminals, game machines, personal digital assistants (PDAs), palmtop computers, etc., character input is often required. The touch screen input method is gradually replacing the original keyboard design due to its good scalability and flexibility, and has become an increasingly common method. At present, there are mainly two ways of touch input in practice: [0003] First, the touch input method on the soft keyboard. In this input method, the user clicks a virtual button in the soft keyboard displayed on the di...

AI Technical Summary

Problems solved by technology

Specifically, in the first way, the user's input content is limited to the display of the soft keyboard, and the display of the soft keyboard will occupy most of the screen area, which affects other display content on the one hand, and limits range of input

In the second way, since the user must completely write out the content (for example, characters or Chinese characters) that he wants to input, on the one hand, it will cause loss to the touchpad itself, and on the other hand, the accuracy of recognition is high, so Wrong input is often generated due to wrong recognition, and the size of the touchpad must be large enough to write the input content, which is inconvenient for the miniaturization of the device
