Smart Touch Kit II Operation Summary

The Smart Touch Kit II allows you to transform any projection screen or LCD screen into a touchable surface. It supports finger touch for writing and control, and multi-touch for up to ten users simultaneously. Installation is designed to be simple, often involving mounting an emitter above the screen and a camera on the projector or ceiling. The device can turn flat surfaces like boards, walls, and LCDs into interactive touch screens and can be operated using any non-transparent object as a pen.

Troubleshooting and error codes

Problem Solution
Hand touch operation is not working properly (Error: "Not a valid USB Key for hand touch whiteboard")
  • Open "Device Management" > "Image Device", check for "USB2.0 PC Camera".
  • If found, the camera may need repair.
  • If not found, check camera/computer connections.
  • Reconnect using another USB port.
  • Reconnect using another USB cable.
  • Reconnect using another camera.
  • Contact the factory if the problem persists.
Auto-calibration is successful, but there is inaccuracy with mouse pointer and finger or IR pen
  • Open "Tuning Webcam Image Mode" (Installation and Debugging menu) and check webcam image proportion.
  • Open "Tuning Laser Transmitter Image Mode" (Installation and Debugging menu) and check if the laser beam is within 4mm above the projection screen.
  • Contact the factory if the problem persists.
Auto-Calibration process failure
  • Select "Adjusting Webcam Image Mode" and check for display issues (dazzling, white/black screen, flickering).
  • Shift to "Tuning Laser Transmitter Image Mode" twice and check for brightness changes. Use another camera if the screen is dark.
  • Analyze "black and white checkerboard" brightness. Adjust "average image brightness" and "Light Gray" settings as needed (e.g., high brightness: avg brightness down to 40, Light Gray up to 250; low brightness: Avg Brightness up to 140, Light Gray up to 250).
  • Contact the factory or perform manual calibration if the problem persists.
Inaccurate performance on top corners or non-smooth writing
  • Check for lightspot in non-smooth areas. Replace emitter if none.
  • If lightspot is small, adjust brightness coefficient to around 170.
  • Perform lightspot sampling.
  • Adjust "Minimum Width" and "Light Spot Minimum Height" to 1 in the "config" file.
