Ball Catch

In an open, calm landscape, a friendly launcher sends balls toward the patient in varying arcs. The patient must predict each trajectory and catch the ball with either hand — or alternating hands. A caught ball dissolves with a brief sparkle, and the next throw is on its way.

Launch speed, arc spread and the number of simultaneous balls grow level by level; soft nature ambience and haptic feedback keep the experience alive.

Catching is the body's dialogue with time: trajectory prediction, timing, and hand-eye coordination. Engaging both hands trains motor symmetry, while varied angles activate the visual field and trunk rotation.

1. Rebuilding reflexes and anticipatory movement after stroke and TBI
2. One-sided upper-limb weakness — targeting the weaker hand
3. Balance and movement confidence in older adults

Pick a level set and align the scene direction and height during preparation; then start the exercise. If the goal is strengthening the weaker hand, choose levels that require a specific hand.

1. Ball speed, launch arc and simultaneous ball count are configurable in the Level Designer.
2. Watch the left/right breakdown to monitor symmetry.
3. Recommended level duration is 90–150 seconds.

1. Catch rate (caught / total throws)
2. Response time and prediction quality
3. Left- vs right-hand performance breakdown
4. Survival time and total score
