Input method and device based on touch screen

Abstract

The invention provides a touch screen based inputting method. The method comprises steps as follows: a pre-operating point input through induction is detected, and distance between the pre-operating point and a screen is determined; whether the distance between the pre-operating point and the screen meets preset distance is judged; if yes, a target area corresponding to the pre-operating point is amplified and displayed; information input through the amplified target area is received. The pre-inputting point on the screen is induced in real time, if the distance between the pre-inputting point and the screen meets the preset distance, the target area corresponding to the pre-operating point is amplified and displayed, so that targets can be accurately selected through the amplified target area, the error rate is reduced, and the input rate is increased.

Description

technical field [0001] The present invention relates to the field of terminal equipment, in particular to a touch screen-based input method and device. Background technique [0002] With the development of terminal equipment, terminals such as mobile phones have become indispensable products in people's daily life. The input of terminal equipment has also evolved from the initial keypad to today's touch screen. The soft keyboard input mode based on touch screen has been widely used. Applications. [0003] Although the size of the terminal touch screen is getting larger and larger, due to the limitation of the terminal device itself, the size of the touch screen is still small, especially the handheld electronic device. The common soft keyboard usually displays multiple elements on one main screen. For example, for the letter interface, 26 letters are displayed on one main screen, so that each key in the virtual soft keyboard is displayed relatively small. When the user is ...

[0003] Although the size of terminal touch screens is getting larger and larger, due to the limitations of terminal equipment itself, the size of touch screens is still small, especially handheld electronic devices

The common soft keyboard usually displays multiple elements on one main screen. For example, for the letter interface, 26 letters are displayed on one main screen, so that each key in the virtual soft keyboard is displayed relatively small. When the user is inputting, it is difficult to select each letter accurately, the error rate is high, and the touch input rate is also reduced

Traditionally, in order to improve the correct rate of input, the clicked button is enlarged and displayed at the moment of clicking, but at this time the button has already been selected for input, and the display size does not actually have much effect
