Abstract

The invention relates to a light sensing based gesture identification system and method. The system comprises a microprocessor, a display screen and one or more IC chips arranged on the border of the display screen, wherein each IC chip is integrated with an LED control circuit, an LED lamp and four light sensors; the LED control circuit is used for controlling the color and intensity of light emitted by the LED lamp; the LED lamp is used for emitting the light under the control of the LED control circuit; the light sensor is used for receiving a simulated light change signal generated when the light emitted by the LED lamp is changed by an external gesture action, converting the simulated light change signal to a digital light change signal and sending the digital light change signal to the microprocessor; and the microprocessor is used for identifying the received digital light change signal to obtain the gesture action so as to control the display screen to perform operation corresponding to the gesture action, and the gesture action includes pressing and moving. According to the light sensing based gesture identification system and method, the non-contact screen operation can be performed according to gesture identification.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a gesture recognition system and method based on light sensing. Background technique [0002] Human-computer interaction refers to the process of information exchange between humans and computers using a certain dialogue language to complete certain tasks in a certain interactive way. Human-computer interaction devices have gradually penetrated into people's lives, and the biggest manifestation at present is the touch screen. [0003] Traditional LCD screen operations are usually operated through resistive or capacitive touch screens. The working principle of resistive touch screens is mainly to operate and control the content of the screen through the principle of pressure sensing. The screen body of resistive touch screens is a piece that is very close to the display surface. Coordinated multi-layer composite film, wherein the first layer is a bottom layer o...
