3.4.4 Tap-and-Hold Gesture

A tap-and-hold gesture is defined as a long finger touch followed by a release (see Figure 9). Just like a tap, the tap-and-hold has a min limit and a min hold limit that defines how long the finger must remain touching to qualify as a valid tap-and-hold gesture. The software parameters are TouchSampleCount_Min and TouchHoldSampleCount_Min.
