How to play
Sit back on a stable chair with both feet on the floor. Follow the left or right cue and make one comfortable knee lift before the gate reaches the traveler. Touch the matching button or use the arrow/A/L keys, or choose private local camera tracking after calibration.
Choose alternate, left-only or right-only play, then low, middle, high or mixed gates. Five speed profiles change the real gate travel time. Camera play pauses when body tracking is lost.
Safety and privacy
Clear the area, keep the chair stable and use only your personal comfortable range. Stop for pain, dizziness, breathlessness, chest discomfort or unusual fatigue. The camera is processed in your browser; raw video and body landmarks are not stored.
