This product emits infrared light from the lower end of the product to detect objects such as fingers. When an object passes through the area illuminated by the infrared light source, any infrared light reflecting off the object is detected by the sensor. Information on the position and movement of the object is then analyzed to perform the product’s role as a keyboard.

Sensitivity: difference in thickness, shape, and color of the user’s fingers or operating environment result in differences in the amount of reflected infrared light. If the amount of reflected infrared light is appropriate, the sensor will have no problem detecting objects such as fingers. However, if the amount of reflected infrared light becomes low because of the causes mentioned above or some other cause, the keystroke recognition rate may decrease or your keystrokes may not be recognized at all. On the other hand, if the amount of reflected infrared light is too high, the keystroke recognition may become too sensitive or a “hovering Effect” may occur where a keypress may occur when you have not yet touched the projected surface. See section “Adjusting the Sensitivity” for corrective steps.

Conditions to Avoid

  • 1. Avoid direct sunlight.
  • 2. Avoid low color temperature light source, such as tungsten, halogen, or incandescent lamp.
  • 3. Avoid uneven or irregular surfaces. Place the product on flat surfaces.
  • 4. Avoid a table or surface that is as transparent or reflective as glass or mirror.
  • 5. Avoid placing any objects within the space between the main unit and the laser projected keyboard layout


Because this product uses infrared rays, strong infrared radiation from direct or reflected sunlight or from tungsten (halogen or incandescent) lighting may cause operating error.


Although this equipment is classified as Class 2 laser product, for your safety, do not directly expose your eyes to pattern projection beams or infrared rays.
