3. How this Product Works
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.
(Hovering: keystroke is recognized before your finger touches the projection surface.)
Therefore, it is necessary to compensate for differences in finger characteristics or operating
environment, and this can be accomplished by adjusting the sensitivity of your projection keyboard.
Given the same amount of reflected infrared light, increasing the sensitivity will produce the effect
of a higher amount of reflection, whereas decreasing the sensitivity will produce the effect of a lower
amount of reflection.
With the sensitivity set to its minimum value, repeatedly press a key that is relatively far from the
sensor (Spacebar, CTRL, etc.) to increase the sensitivity. As soon as your keystroke is recognized,
stop adjusting the sensitivity and set the final setting value to one or two notches above original
setting.
