AIDE

This is a page for keeping track of notes on the AIDE (Alternate Input Device Events) specification. This specification is intended to define an advanced pointing-device interface, to expose distinct features of specific devices such as pen/tablet inputs and multi-touch trackpads, including gesture-based events.

This is very rough first draft, pulling items from email discussions. It is by no means complete, and is intended to serve as a template for other people to add more information.

Use Cases

  • Pinching to zoom into a map
  • Dragging an element from one place to another
  • Rotating element


Requirements

  • Should reuse existing API wherever possible
  • Must include pressure sensitivity
  • Must include low-level APIs for position and movement
  • Must include multi-touch
  • May include high-level gestures, including but not limited to:
    • swipe
    • pinch
    • twist
  • Should consider mapping to legacy events for backwards compatibility with legacy content, if possible (e.g. "swipe left" might have left-arrow key event as default action)
  • May include accelerometer / shaking API
