Abstract

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, or touchscreen. For compatibility with existing mouse-based content, this specification also describes a mapping to fire Mouse Events for other pointer device types.

Status of the Document

This section describes the status of this document at the time of its publication. A list of current W3C publications and the latest revision of this technical report can be found in the W3C standards and drafts index at https://www.w3.org/TR/. 

This specification is an update to [PointerEvents2]. 

This revision includes new features: 
 
  * altitudeAngle 
  * azimuthAngle 
  * pointerrawupdate event, for high frequency events 
  * access associated coalesced events, for a more precise handling of pointer movement data 
  * access built-in predicted events, to reduce perceived latency 
  * new CSS touch-action values: pan-left, pan-right, pan-up, pan-down  

This revision also includes clarifications: 
 
  * strategies and approaches in how a user agent assign a pointerId 
  * suppressing a pointer event stream 
  * boundary events caused by layout changes 
  * relation with click, auxclick, and contextmenu events 
  * considerations to avoid fingerprinting with factory calibration information  

Before this specification exits Candidate Recommendation, two or more independent implementations must pass each test, although no single implementation must pass each test. 

This document was published by the Pointer Events Working Group as a Candidate Recommendation Snapshot using the Recommendation track.

Publication as a Candidate Recommendation does not imply endorsement by W3C and its Members. A Candidate Recommendation Snapshot has received wide review, is intended to gather implementation experience, and has commitments from Working Group members to royalty-free licensing for implementations.

This Candidate Recommendation is not expected to advance to Proposed Recommendation any earlier than 27 May 2025.
