Streams​

A Stream is a timeline of one modality:

  • SkeletalPose stream
  • ContactState stream
  • Input stream

Samples​

A Sample is one timestamped value inside a Stream.

Events​

Events describe semantic actions such as:

  • Grasp start
  • Manipulation event
  • Button presses

  • streams

All references must resolve.

The Core Spec does not enforce a timeline alignment policy.
