How this product works:
When the user presses a key on the projected, the infrared layer is interrupted. This produces IR reflections that are recognized by the sensor in three dimensions, Allowing the system to assign a coordinate.

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