Abstract

The invention discloses a multi-contact input method and device based on a touch screen, used for solving the technical problems of lower efficiency, complicated operation and the like when multi-point input, such as combination key input, composite key input and the like, is realized in the traditional input method based on the touch screen. According to the invention, the input by combination keys, composite keys, window zoom, rapid gesture command and the like is realized through multiple contacts, the operation habit of people is better accorded with, and the input efficiency is improved.

Description

technical field [0001] The invention relates to an input method supporting touch screen input, in particular to a touch screen-based multi-touch input method and device. Background technique [0002] With the development of mobile communication technology, people use mobile terminal equipment for information exchange more and more commonly. In order to facilitate user operation, many mobile terminals are equipped with touch screens. The terminal performs corresponding functions. The virtual key area refers to a touch area on the screen, on which the user can press, hold, press and move, and lift. [0003] In the existing input method based on the touch screen, the input of combined keys and compound keys is realized through a single contact. Keep the key area in a certain state, and then click another virtual key area (key 2), the system determines the action of key 2 according to the state of key 1, for example, when realizing the operation of the key combination Ctrl+A (s...
