Updated Candidate Recommendation: Pointer Events Level 3

The Pointer Events Working Group invites implementations of an updated Candidate Recommendation Snapshot 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, or touchscreen. For compatibility with existing mouse-based content, this specification also describes a mapping to fire Mouse Events for other pointer device types.

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

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

Comments are welcome via the GitHub issues by 4 December 2025.
