Rear projection interactive

Principle and Features
IPS is based on the computer vision technology. When user pressing the finger on the screen, the image will be captured by the camera inside the sensor. And then the driver program will analyze the image, recognize the finger and translate the physcial position of the finger on the projection screen into the logical coordinate of the computer. Related mouse event will also be sent at the same time. Therefore, it functions to open an interface, switch a scene and look up information by touching the screen with fingers or other finger-like objects.
IPS is very adaptable to various environments; unlike ordinary touching screen, it is not subject to natural conditions (e.g., temperature, humidity) of the surroundings.
IPS can be equipped with screens of gradable sizes, distinguishing it from ordinary small-size touching screens.
IPS has a long service life: protected by a transparent glass cover, the projector will not be affected by normal touching.
