redraw/dom/event/touch

To provide quality support for touch-based user interfaces, touch events offer the ability to interpret finger (or stylus) activity on touch screens or trackpads.

The touch events interfaces are relatively low-level APIs that can be used to support application-specific multi-touch interactions such as a two-finger gesture. A multi-touch interaction starts when a finger (or stylus) first touches the contact surface. Other fingers may subsequently touch the surface and optionally move across the touch surface. The interaction ends when the fingers are removed from the surface. During this interaction, an application receives touch events during the start, move, and end phases.

Touch events are similar to mouse events except they support simultaneous touches and at different locations on the touch surface. The TouchEvent interface encapsulates all of the touchpoints that are currently active. The Touch interface, which represents a single touchpoint, includes information such as the position of the touch point relative to the browser viewport.
