Embodiment 1

[0011] The target letter is the letter "S". When the distance between the finger and the screen is less than 0.5 cm, the area of ​​the letter "S" and the adjacent letter keyboards "A", "Z", "D", and "X" will be enlarged by 4 times. The finger continues to point to the position of the letter "S" on the touch screen, clicks on the enlarged letter keyboard, and then the keyboard returns to the initial state after the finger loses contact with the touch screen. Complete a letter correction operation.

Embodiment 2

[0013] Enter English characters. Click the initial letter "G", when the distance between the finger and the screen is less than 0.1 cm, the letter "G" and its surrounding adjacent letter keyboards "d" "r" "t" "h"d" "g" "v" "c" will enlarge the area by 2 times, the finger continues to touch the touch screen, but clicks the adjacent letter "F" by mistake, keeps the finger and the touch screen in contact, and moves the contact point from the letter "F" to the letter "G". , and then the keyboard returns to its initial state after the finger loses contact with the touch screen. Complete a letter correction operation.

Abstract

The invention discloses a method for improving the letter input accuracy rate of a touch screen device by using a non-contact gesture control function. The method includes the steps that: 1, the non-contact gesture control function is used, when a finger approaches but not contacts any letter of a touch virtual keyboard, the target letter key and adjacent letter keys are amplified, so that the accuracy rate of clicking can be improved, and mistaken clicking can be substantially avoided; 2, if the correct letter is clicked, the finger leaves the touch screen, the screen recovers and then the whole letter clicking process is ended; if the incorrect letter is clicked, the finger is kept continuously contacting with the touch screen and slides to the correct keyboard position, then the finger leaves the touch screen, the screen recovers and the whole letter clicking process is ended.

Description

technical field [0001] The invention belongs to the field of information processing, and in particular relates to a method for improving the letter input accuracy rate of a touch screen device by applying a non-contact gesture control function. Background technique [0002] At present, in touch-screen input devices, such as touch-screen mobile phones, PDAs, digital cameras, industrial computers, etc., the most commonly used keyboards for letter input are full-keyboard keyboards and or nine-grid keyboards. Wherein the full-keyboard keyboard refers to a keyboard in which 26 letters in English are respectively distributed on different keys. Jiugongge keyboard The touch keyboard refers to a keyboard in which 26 letters in English are distributed on 9 virtual keys. Due to the size of the screen, the touch virtual keyboard is generally small, and it is easy to click on a letter that is not a virtual key that is needed. The accuracy of the input operation has seriously affected t...
