    40" to 250" laser touch portable interactive whiteboard
    Company Profile
    We are specialized in Image analysis technology and Laser Touch Technology (projection touch technology), which can turn any projection screen into a virtual touch screen. We have applied for / obtained more than 20 patents.  We are the only manufacturer who can produce of projection touch technology production in mass in China.Virtual touch screen can be applied in many fields, such as information Kiosk, self-service kiosk, learning tablet, interactive advertising kiosk, merchandise display, etc. Traditional LCD touch screens have hundreds of millions of sales worldwide each year, However virtual touch screens will gradually replace some of them in the market.  Currently, the companies are integrated our touch module into their products,such as Acer, ViewSonic, PPTV, Haier, Asus, Guangzhou Weichuang, etc. In April 2018. Our company is listed in the Shanghai Stock Exchange Center, the stock code 300200.

    Laser Curtain Technology

    FP4 Board with 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 finger or any non-transparent object 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.

    Features of Laser Image Calibration Technology(LICT)
    1. Built-in red reference laser can adjust the laser film height through the knob without opening the projector and computer.
    2. Finger precision touch, support 100, 120, 150, 200, 260 inches
    3. Light weight (the main product consists of laser emitter and signal sensor, the total weight of single product does not exceed 500g)
    4. Automatic calibration, completed within 5 seconds, the success rate is more than 95%.
    5.10 points touch
    6. Multiple gesture recognition
    7. High cost performance
    8. The shortest projection ratio: 0.15-1.36 can be adapted to any projector on the market.
    9. Signal sensor and laser emitter can be combined according to different size requirements.

      Product Installation

      Function Introduction of FP4

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

      2.Use full-screen. Projecting screen can be very closer to the frame of the whiteboard, it can achieve full screen mode and use all of available screen.

      3.Support plenty of gesture recognitions.

      Gesture recognitions in Windows

      Gesture recognitions in education software GL board

      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.
    (Picture A)          (Picture B)

      5.Support 10 points finger touch (10 people can write together,10 people can write together in Windows Paint too) (as Picture B)

      6.Support Larger active size. Support 40-250” for the room without sunlight through the windows.

      7.Portable, high integration and easy to install. Total weight is only around 500g. The installation is very easy, just needs to put the emitter part on the upper of projection Screen,

      and the sensor mounted to projector or ceiling. No skill needed.

            8.Easy to adjust emitter:it is embedded one ir light with three white magnet as referrals.to adjust laser curtain by two gears.it adjusts laser curtain in vertical direct by gear A and in horizontal direct by gear B.it does not need to open projector and computer,just to check the position of red line in white magnet is ok.

      9.Sensor with the flash chip. Don’t need to calibration if you change another computer with the same resolution ratio. It saves time, and makes the use easier.

      10.The product is smaller. Emitter part size is 5.3cm*18.8cm*3.0cm; it can put on the board directly.

      11.Wireless connection. Wireless connection between emitter and sensor, and sensor wireless control the emitter’s on and off. This makes product more durable.

      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.

      14.Support double screen (Mode of short throw finger touch double screen: FP4WENGLA4; support extend screen, blended screen, or just two screen together).

      Software will make the write will not disrupted in joining together place of two screen.
