Abstract

The invention discloses a rotary laser virtual keyboard system and relates to the technical field of laser virtual keyboards. The system comprises a microprocessor, an angle adjustment device and a rotary device, wherein the microprocessor performs data transmission with terminal equipment through a Bluetooth module or a USB data line; the microprocessor is connected with an infrared camera; the microprocessor is connected with a linear laser emitter; the microprocessor is connected with a keyboard pattern projector; the angle adjustment device comprises a micro-motor and an angle sensor A; the rotary device comprises a motor and an angle sensor B; the microprocessor is connected with the micro-motor, the motor and an A / D converter; the A / D converter is connected with the angle sensor A; and the A / D converter is connected with the angle sensor B. According to the system, through the functions of the microprocessor, the angle adjustment device and a rotary base, the problem that an existing laser virtual keyboard cannot adjust the projection size of a keyboard pattern according to a personal habit and hand size is solved.

Description

Technical field [0001] The invention belongs to the technical field of laser virtual keyboards, and particularly relates to a rotary laser virtual keyboard system. Background technique [0002] With the continuous development of science and technology, people's demand for the way of life and the use of tools is becoming more and more convenient, making notebook computers thinner and thinner, and computer performance requirements are getting higher and higher. As the input device of the computer mainframe, the keyboard and mouse are essential parts for users to operate the computer. People will give priority to its convenience characteristics while not affecting input efficiency. [0003] At present, the laser virtual keyboard has begun to enter people's lives with its small size, portability, and convenient operation. However, the projection angle of the keyboard pattern projector in the laser virtual keyboard is fixed, so that the size of the keyboard pattern projection and the ...
