Andriod/Windows Interactive Module
Interactive Module with design of light weight applies to modifying of various long, short and ultra-short focus projectors, to let projectors have interactive whiteboard functions. This product utilizes the technology that high-speed IR camera lens tracking moving objects, realizes human-computer interactive function. It adopts HID interface design, compatible with USB 1.1, 2.0,3.0; Using newer, high efficient video compression algorithm to realize that image can be transmitted with high FPS in conditions of low bandwidth, improved product adaptability under various light interference.


1. The technology principle
A. The principle of photoelectric positioning technology is adopted, which can be used together with normal projector to transfer any projector surface into interactive  whiteboard.

B. The interactive module is equivalent to the infrared high-speed tracker, and the electronic pen or pointer emits 850nm infrared light. The interactive module is responsible for receiving the signals emitted by the electronic pen and pointer in the projection range.

C. Infrared filter helps portable whiteboard filter other stray light and only receives 850nm infrared light, which makes positioning more accurate and writing faster.

D. CameraTouch/Interactive Projector Server: the Server is the communication tool between the portable whiteboard and the computer. Without the Server, the Interactive module cannot be identified by the computer/Projector.

E. E-Note: multi-point writing program, can be in any operating system to achieve multi-person writing function (only Windows XP, Windows 7, Windows 8, Win10 system)

F. System compatibility: Windows XP, Windows 7, Windows 8, Linux(some version of Ubuntu, only Server support, e-note does not support), Android system (e-note writing software does not support)

G. Positioning function: click 4 (25) red cross to enable the interactive module to accurately catch the running track of the electronic pen and pointer.(there is no need for the user to reposition , because it has been set before delivery;Unless the customer finds the difference between the click red cross of the electronic pen and the cursor is more than 1-2cm, it needs to be repositioned.


2. Main categories: Long-focus Module, Short-focus Module, Ultra short-focus Module
Long-focus interactive module for long-focus projector (4 positioning points)
Short-focus interactive module for short-focus projectors (25 positioning points)
Ultra short -focus interactive module for ultra short throw projector (25 positioning points)
