Touch Screen Application with Infrared Module
1) The infrared surface emitted by the line laser covers the entire screen. The thickness of the infrared surface is about 2mm. When a finger or other object is close to the touch screen, the infrared surface of the laser forms light spots. The infrared camera captures these light spots and transmits the image to a computer. The company processes and analyzes these screens through software, then recognizes the location and touch events.
2) Using laser plane multi-touch technology to realize multi-touch devices is a simple and inexpensive method. Most devices require 4-8 laser heads to illuminate the plane from the four corners and sides of the screen.
