General activity only, not medical measurement or treatment. Sit in a stable position and stay within a comfortable reach. Stop for pain, dizziness, breathlessness or unusual fatigue.
How to play
- Sit in a stable position and choose left, right or mixed directions plus a comfortable reach distance.
- Use touch or mouse, or enable optional local camera fingertip tracking.
- During calibration, move only through a comfortable area. The activity uses the middle portion of that range.
- Aim at the moving fish and hold briefly to hook it.
- Return to the reel, then reach to the green marker. Repeat the alternating motion three times to land the fish.
Pace and comfort
Five speed settings change the fish movement and task time: 1/8×, 1/4×, 1/2×, 1× and 2×. Begin slowly. Short, medium and full refer to portions of your calibrated comfortable range, not a prescribed distance.
