Gesture control method and device

Abstract

The invention provides a gesture control method and a gesture control device. The gesture control method is applicable to an electronic device with a display screen. The gesture control method includes firstly, detecting first gesture operation which is carried out by a user in three-dimensional space at the front of the display screen so that an operation plane can be defined; secondly, computing a proportion of the palm of the user to the coverage of the operation plane; thirdly, dividing the operation plane into a plurality of operation areas according to the proportion and dividing a display plane of the display screen into a plurality of corresponding display areas; fourthly, detecting second gesture operation which is carried out by the user in the operation plane and controlling displayed articles in the corresponding display area according to the certain operation area where the second gesture operation is carried out.

Description

technical field [0001] The present invention relates to a gesture control method and device, and in particular to a gesture control method and device for gesture control in three-dimensional space. Background technique [0002] Today's consumer requirements for the appearance of electronic devices tend to be light, thin, short, and small, and this requirement makes the volume and weight of electronic devices quite limited. Recently, the application of touch screen has become more and more popular. For portable devices such as smart phones or tablet computers, the touch screen can be used as the display and input interface of the device at the same time, and the cost and area occupied by the traditional keyboard can be saved. For desktop computers or notebook computers, consumers can choose to use traditional keyboards or touch screens for control input. [0003] However, in the existing touch screens, whether it is a capacitive touch screen or a resistive touch screen, a pi...

Problems solved by technology

[0003] However, in the existing touch screen, whether it is a capacitive touch screen or a resistive touch screen, a piece of touch glass or film will be added in front of the liquid crystal display (LCD) panel, thus increasing the thickness and weight of the display screen.

Therefore, when the notebook computer is turned on, consumers touch the display screen with their fingers, which may easily cause the notebook computer to shake.

Moreover, there is a certain distance and angle between the display screen of a notebook computer and the consumer, and it is not as free to move as a tablet computer. Therefore, the device type of a notebook computer is not suitable for direct touch with fingers

In addition, direct touch control of the display screen with fingers may easily lead to the problem of fingerprints remaining on the display screen
