3.4.6 Slide Gesture

A slide gesture behavior is similar to a swipe gesture, but is defined as a continuous finger touch with motion where the distance moved meets the minimum distance parameter. Figure 11 shows that as long as the finger is touching the sensor and moves the minimum required distance in any direction, a slide gesture is reported. The software parameters are TouchSampleCount_Min and SlideStepSize.
