HeadVoice replay

Replay recorded sessions (head pose, eye openness and signal quality measured by OpenCV 5; no video) through each interface setup on AWS, and see what the adaptation agent decided and why.

Research and education prototype, not a medical device. Replay uses recorded measurements, so it cannot show how a person would react to a changed layout. Fatigue is simulated by shrinking recorded head movements over the session. Volunteers are not the target users.
