Mobile terminal, touch area recognition device and method

Abstract

The invention provides a touch area recognition device which comprises a detection unit and a display unit, wherein the detection unit is used for detecting a pressing physical amount in a touch process when sensing a touch action of a user on a touch input device; and the display unit is used for generating a recognition control picture according to the pressing physical amount detected by the detection unit and displaying the recognition control picture on an area on which the touch action is applied, so as to prompt the area touched by the user on the touch input device. Correspondingly, the invention also provides a mobile terminal having the touch area recognition device and a touch area recognition method. According to the technical scheme of the invention, the actual area touched by the user can be prompted and the selection range for user regulation can be prompted, so that wrong selection of key values is avoided and the input efficiency is increased.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular, to a mobile terminal, a touch area recognition device and method. Background technique [0002] Touch screens are widely used in various terminals. Users use fingers or other writing tools to select and input information on the touch screen. Due to the emergence of capacitive touch screens, users basically use fingers to input information. When using fingers to select and input information, due to The contact area between the finger and the screen is large, and it is easy to press the wrong key value when selecting input information. For example, in the dial pad, the distance between the keys is relatively close, and the area of ​​each key is small. When using a finger to input a phone number, it is easy to press the wrong key value, and multiple corrections are required to finally complete the input of the phone number. However, there is no way in the related art to prompt ...

[0002] Touch screens are widely used in various terminals. Users use fingers or other writing tools to select and input information on the touch screen. Due to the emergence of capacitive touch screens, users basically use fingers to input information. When using fingers to select and input information, due to The contact area between the finger and the screen is large, and it is easy to press the wrong key value when selecting input information. For example, in the dial pad, the distance between the keys is relatively close, and the area of ​​each key is small. When using a finger to input a phone number, it is easy to press the wrong key value, and multiple corrections are required to finally complete the input of the phone number. However, there is no way in the related art to prompt the user whether to select the wrong key value. In some cases, it cannot be adjusted, and the selection input needs to be re-selected, which affects the efficiency of the user's selection input
