---Laser Image Calibration Technology

Before the Laser Image Calibration Technology, interactive projectors mainly adopt Optical Technology or TI Pointblank Technology, Neither of them can support Finger Touch. After the two-year research and development, we successfully developed an innovative technology: Laser Image Calibration Technology---LICT. This technology has been applied to the short focus projectors and even ultra short focus projectors. When the projector adopts this technology, it will support finger touch and multi-touch. No need electronic whiteboard, users can use finger or any non-transparent objects to control the computer, writing, making note and all the operation as normal interactive whiteboards.

The modules come in two parts: emitter and sensor. Emitter can be attached on any flat surface like wall, Board, etc. It emits infrared laser on the projection surface which is about 1mm thick and parallel with the projection screen, 1-2mm above from the screen. when the fingers or any non-transparent objects touch this virtual surface, the light will be reflected and detected by the sensor at the top. Computer will figure out the position of the mouse by high accurate calculation of light position.

1.Finger Touch and Portable: any other product cant both features

2.Automatic Calibration: any solid Interactive Whiteboard cannot support.

3.Remote Control: any solid Interactive Whiteboard cannot support.

More and more projectors have been equipped with interactive functions, but all of them have to work with the infrared pen. In terms of users' experience or interactive functions, they cannot beat the ordinary interactive whiteboard with finger touch. As more and more manufacturers begin to produce the interactive projector, the projector's interactive function is no longer a bright spot and the projector's competition is hot. If the manufacturer can integrate the finger touch function into the projector, it will undoubtedly increase the competition and raise the company's popularity and avoid vicious competition of similar products.

Finger Touch Module includes 2 parts: image sensor and emitter. Image sensor can be integrated in the projector (the image sensor can be made to order as requirements), the emitter can be mounted on any flat surface. As the following pictures:
