Research Needs & Knowledge Gaps

Research Needs

Big Questions

  • How can universal gestures be established & whose job is that?
  • What are uses of gestures during periods of automated/non-automated driving?

Behavior observation

  • Which gestures are done unintentional during driving?

Knowledge Gaps

Performance consideration

  • Experimental evidence for performance
  • What domains are gestures actually optimal for?
  • Where are gestures really useful?

Gesture discovery

  • How do users know a gesture is there?
  • How can we communicate what a gesture is to a user?

Technology consideration

  • How “complete” should a gesture be? -> trade-off between completeness & recognition
  • Capability of gesture trackers – limitations
