Face your palm to the camera.
Keep your hand open and roughly perpendicular to the camera so all
your fingers are clearly visible. Avoid showing your hand edge-on.
☝️
Point with your index finger.
Curl the other fingers in (like a "1" gesture) and keep your index
finger fully extended. The fingertip is what gets tracked.
Don't point toward the camera, point upward for better tracking.
🐢
Draw slowly and smoothly.
Going too fast causes the tracker to lose your finger. Aim for a
full circle in about 3–5 seconds — roughly the pace shown below.

Make a fist to score.
When you finish your circle, close your hand into a fist to lock in
your score. (Closing the loop also auto-scores.)
