Details

The horizontal velocity (in pixels per second).

This is only affected by the event types that the Observer is watching. So, for example, type: "wheel,touch" would track the velocity based on wheel and touch events (not pointer or scroll). By default, touch and pointer events are only tracked while pressing/dragging but if you define an onMove (which is mapped to "pointermove"/"mousemove" events), it'll be tracked during any movement while hovering over the target.
