The Status flags that can trigger one of these gestures are:

• Hand Presence flag is active while the user's hand is in the sensing space.

• Hand Inside flag is active while the user's hand is in the sensing space approximately centered above the

sensor.

• Hand Hold flag is active while the hand is not moving and one of the above Status flags is active, the selection

depends on ActiveOutside.

The behavior of the Status flags and corresponding gestures can be adjusted to suit a specific application. The

Gesture and Presence/Hold state visualization windows offer immediate feedback upon adjustment.

The adjustable parameters are:

ActiveOutside

– Chooses if Hand Hold flag and Presence gesture can be active when the user is outside the sensor, but

still in sensing space.

• ActiveOutside checked (default) means that Hand Presence is required to set Hand Hold and that

Presence Duration starts counting on the rising edge of Hand Presence Status flag;

• ActiveOutside unchecked means that Hand Inside is required to set Hand Hold and that Presence

Duration starts counting on the rising edge of Hand Inside Status flag.

Presence Duration

– This is the time during which the selected Status flag must be active to trigger a Presence gesture. This

time starts counting on the last rising edge of the selected Status flag. The gesture is only triggered once

for each rising edge of the flag.

Hold Duration

– This is the time during which the Holding Hand flag must be active to trigger a Hold gesture. This time

starts counting on the last rising edge of the Holding Hand flag. The gesture is only triggered once for

each rising edge of the flag.

Hold Tremble Threshold

– This value specifies how much the hand can move and still be considered as holding. For high values,

the hand can move while the Hand Hold flag is still high. For low values, only a slight movement is

necessary to clear the Hand Hold flag.

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.
