Gain & Threshold

The Gain adjusts the signal strength injected by the Touch Controller on the Touch Sensor. Gain values range between 0 and 7.
Thicker glasses and bigger Touch Sensors will require a stronger signal (higher GAIN values).

The Threshold adjusts the threshold level of what is considered a touch. Values vary between 0 and 50.

How to adjust Gain and Threshold

  1. Set Gain to the lowest value (“0”) and wait 2 seconds. Note: Every time the Gain value is changed you need to wait 2 seconds before you can touch the screen (a ‘do not touch’ image will flash for 2 seconds).
  2. Touch while increasing the Threshold until achieving a good touch performance. Drag the touch and continue to increase the Threshold until the drag is continuous in the whole Touch Sensor, by testing thoroughly both the center and the borders of the Touch Sensor. When the drag color changes it means that detection has been lost.
  3. If Threshold reaches a maximum value, and a good touch experience hasn’t yet been achieved, increase the Gain one value and repeat step number 2
  4. Keep repeating the steps 2 and 3 until you achieve a good touch performance.

Note 1: If you achieve a good touch performance but false touches are still happening, please check the Shield feature.
