Sensor Touch Gestures

Figure 4-4. Sensor Touch

A Sensor Touch is a multi-zone gesture that reports up to five concurrently-performed touches on the

system’s electrodes.

The Sensor Touch provides information about touch and tapping:

The Sensor Touch indicates an event during which a GestIC electrode is touched. This allows

distinction between short and long touches.

The Tap and Double Tap signalize short taps and double taps on each system electrode. The tap

length and double tap interval are adjustable.

–

Single Tap Delay: A single tap is detected when touching the surface of an electrode first

and after the hand is pulled out of the touch area. The Single Tap is only detected when the

timing between the touch and the release of the touch event is smaller than the adjusted

delay. Increasing the time allows the user more time to perform the tap. The range for the

adjusted delay can range between 0s and 1s.

–

Double Tap Delay: The double tap is detected when two taps are performed within the

adjusted delay. The range for the adjusted delay can range between 0s and 1s. The smaller

the selected delay is, the faster the two taps have to be executed.
