Problems solved by technology

Infrared sensor touch screen is only suitable for a variety of non-open-air occasions
[0005] Moreover, almost all touch screen technologies need to touch the screen, and the screens touched by fingers are not only easy to breed bacteria
Even touching a certain position for a long time will cause the light transmittance of the touch screen to decrease obviously or the surface layer will be soft and blistered. At this time, only change the touch button of the touch software to make the touch button leave this position

Embodiment Construction

[0074] The first specific example is figure 1 and figure 2 It is a schematic diagram of the structure of the contact or non-contact infrared laser multi-touch screen of the present invention. It can be seen from the figure that the 6 emitted by the 3 is installed on the four corners of the 1, and can be received by the upper 4 on the left and the upper side ; 3 is an infrared laser, which emits a word, and generally selects 6 with a narrow band; the 6 emitted by the four corners is surrounded by 4 as an infrared sensor, and 4 needs to be on the same horizontal line as the 6 emitted by 3; 2 is a liquid crystal display screen. 5 can touch all 1, so the area of ​​1 is smaller than 2; 1 is a touch panel made of highly transparent, highly light-guiding, and insulating materials, and a 6 that can block the emission of 3 is attached to 1. Infrared, and has a dust-proof, anti-static, anti-scratch protective film; the controller components include an input controller and an output co...

Abstract

The invention provides a contact or non-contact multi-point infrared laser touch-control device. The device is characterized in that the touch-control operation can be realized no matter a touch panel is in contact or not; the multi-point touch can be simultaneously conducted; the positioning is accurate; the algorithm is more effective; the calculations about the coordinates of touch point positions are accurate, reliable, and convenient; circuit elements and the structure are simple; the screen recognition and the screen calibration are convenient; the cost is low; and a multi-point touch-control large screen with any sizes can be flexibly constructed. The system comprises hardware including an infrared laser, a projector, an infrared camera, optical YAKELI, glasses and the like and software including a multi-point touch-control system platform and multi-point touch-control application software. The implementation of the device of the invention can realize the harmonious human-computer interaction, and generate the great social and economic benefits.

Description

technical field [0001] The invention relates to an infrared laser touch device, more specifically, the invention relates to a touch device capable of single-point or multi-point touch with contact or non-contact touch. Background technique [0002] At present, the touch screen is only a tool to replace the mouse and keyboard. Due to cost considerations, most control panels use resistive type. Infrared, ultrasonic, or surface capacitive technologies are becoming more and more popular along with diversified large-size panel application products. Large-size touch panels that are easy to use and facilitate interaction have shifted from industrial and commercial applications to the surrounding areas of people's lives. [0003] With the development of human-computer interaction, the use of human feeling and action (such as voice, handwriting, posture, sight, expression, etc.) development process. It has become an inevitable trend for the easy-to-use and intuitive touch technolo...
