The Pointer Events Working Group has published a First Public Working Draft of Pointer Events Level 3. The features in this specification extend or modify those found in Pointer Events, a W3C Recommendation that describes events and related interfaces for handling hardware agnostic pointer input from devices including a mouse, pen, touchscreen, etc. For compatibility with existing mouse based content, this specification also describes a mapping to fire Mouse Events for other pointer device types.
