📱 Set up your phone first

This study tracks where your eyes look. For the data to be useful, your phone needs to stay completely still.

🪑
Place your phone flat on a table, desk, or any hard surface — screen facing up.
📐
Or lean it against a stand, book, or the wall — anything that holds it steady.
🙅
Do NOT hold the phone in your hand. Any movement during the study makes the eye-tracking inaccurate.
💡
Good lighting on your face — daylight or a lamp in front of you. No bright window behind you.
📏
Sit ~40 cm away so the camera sees your full face.
