Open issues/risks

Stage 1: Definition

1. Feature overview

Touch Events part 1 exposed single-touch events to web content.

Touch Events part 2 will extend that to expose multi-touch events to Fennec chrome and web content. This will allow authors to build web pages that interact with multiple touch points at once. It will also be useful in Fennec chrome for implementing multi-touch gestures in JavaScript.

2. Users & use cases

  • Expose multi-touch events (multiple simultaneous touch events) to content in Fennec.
  • Compatibility with existing web content.
  • Conformance with the W3C Touch Events editor's draft, including new attributes like radius/force/angle where available.
  • Compatibility with a common subset of Safari/Opera functionality.
  • Use touch events to implement gestures in Fennec chrome JavaScript.

3. Dependencies

`

4. Requirements

  • No visible performance regressions.
  • UI gestures (e.g. pinch zoom) still work unless pages deliberately prevent them.

Non-goals

  • 100% compatibility with Safari or other browsers.
  • Enable W3C touch events in desktop Firefox (will be done in future versions).
  • Defining new gestures - will be done separately in Fennec/Features/gestures.
  • Exposing gesture events to web content.
