Abstract

The invention discloses an input method for a touch screen, comprising a position coordinate which is closest to a contact of a touch-control body that is arranged in the upper region of the touch screen. A character which is closest to the position coordinate or a soft keyboard key on the touch screen is amplified and displayed to facilitate the bunt of the contact on the amplified character or key. An input device for the touch screen and a communication terminal thereof are also disclosed. The invention has the advantages that under the condition that the touch-control body does not bunt the touch screen, the coordinate of the character or the key which is closest to the position coordinate is determined by capturing the position coordinate of the contact of the touch-control body; the character or key is amplified and displayed by the coordinate of the character or the key; users can carry out the input operation according to the character or the key which is amplified and displayed before the bunt.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and communication terminal using a touch screen input. Background technique [0002] With the development of communication technology, the application of multimedia interactive terminal equipment using computers, mobile communication terminals, etc. as information carriers is increasing day by day. , Space-saving new devices are getting more and more attention from system engineers. Taking the mobile phone in the mobile terminal as an example, after the touch screen on the mobile phone displays the keyboard to be input, the user can use a stylus or a finger to touch the corresponding character of the displayed keyboard on the corresponding position of the touch screen to complete the character input purpose. [0003] The inventor found the following technical problems in the prior art during the process of realizing the present invention: due to th...
