3. How this product works
When the user presses a key on the projected keyboard, 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.
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 surface, Put the product on flat, opaque surface.
4. Avoid putting any objects within the space between the main unit and the laser
projected keyboard layout.
Note:
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.
