## Recording Protocol
|
| 43 |
+
For each gesture:
|
| 44 |
+
|
| 45 |
+
Countdown (4s) ← not recorded
|
| 46 |
+
Hold gesture (5s) ← recorded
|
| 47 |
+
Relax countdown (8s) ← not recorded
|
| 48 |
+
Rest (5s) ← recorded
|
| 49 |
+
Repeat × 6 rounds

- Session 1 contains a minor labeling error in the last repetition of pinch
|
| 76 |
+
- All sessions used for training the final model
|
| 77 |
