Today, W3C published two independent specifications related to touch events. The Pointer Events Working Group has published the Pointer Events specification as a Candidate Recommendation. This specification unifies input from touch surfaces, mouse, and other devices into a single model for ease, flexibility, and consistency of development. The Web Events Working Group also advances the earlier Touch Events version 1 specification to Proposed Recommendation. This specification standardizes an earlier model which works only for touch events. Comments on Touch Events welcome through 6 June.
