Laser Image Calibration Technology (LICT) 
“PojectoMust – I”is similar to ProjectoMust A1 withadditional two parts: emitter and sensor. Emitter can be attached on flat surface. It emits infrared laser curtain on the surface which is about 1mm thick invisible light and parallel with the projection screen surface, 1-2mm above the screen surface. When the fingers or any non-transparent objects touch this virtual surface, the light will be reflected and detected by the sensor. Computer will figure out the position of the mouse by accurate calculating the reflected light position.

Function and features introduction

1. High stability: Use the advanced algorithm to avoid the affect of the light.

2. Requirement for the board: The only requirement for the board or wall is flat and evenness. The board can be with the frame. The projection screen can closer to the frame, even in the edges of the frame, “PojectoMust – I” can work well.

3. Support plenty of gesture recognition: write with single finger; move with two fingers; eraser with palm; two fingers for zoom in& zoom out; two fingers work as scroll bar and so on.

4. 5s auto calibration (as Picture A). Infrared technology and Optical technology only support manual calibration. Our auto calibration is much more accuracy and easier to operate.

5. Support 10 points finger touch (10 people can write together) (as Picture B)

6. Support Larger active size: support 40-100” for the room with sunlight (if the room without sunlight, it can support the active size of 40-120”. 

7. Portable, high integration and easy to install: Total weight is only around 500g. The installation is very easy, just needed to put the emitter part on the upper of projection Screen, and the sensor mounted to projector or ceiling. No skill needed.

8. Sensor with the flash chips: don’t need to calibration if you change the computer with the same resolution ratio. It save time, and make the use easier.

9. The product is smaller. Emitter part size is 3.2cm*16cm*1.7cm; it can put on the board directly.

10. Wireless connection: Wireless connection between emitter and sensor, and sensor wireless control the emitter’s on and off. This make product more durable. 

11. Sensor’s filter with auto push-pull device: When do auto calibration, the filter will be open; after calibration, the filter will be closed automatically. Such action makes the product more stable to defense the interference light, and the auto calibration success easier.

12. Turn common board or wall to touch board. It can turn any flat surface (whiteboard, wall and so on) into finger touchable.

13. Any non-transparent object can be used as pen, like a rolled paper. In any active area, any non-transparent object can work instead of the pen and the mouse.
