This product emits infrared light from the lower end of the device to detect objects such as
fingers. When an object passes through they are illuminated by the infrared light source, any
infrared light reflecting off of an 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 will result in differences in the amount of reflected infrared light.
Please adjust sensitivity that best suits your environment.
Refer to "Section 6: Making Adjustments" on how to adjust sensitivity.
