Fruity Feet control panel. Using the control panel, clinicians can adjust the game to better fit the needs of their patient. Intensity affects the rate at which fruit appears in the world. Left/Right Focus focuses the game activity on the left/right side of the patient, encouraging patients to use their affected side. Fruit Size changes how high players must lift their foot in order to effectively stomp a fruit. Extremity Focus focuses the game activity on the player’s lower or upper extremities. Foot/Hand Mirroring enables an experimental mode that mirrors the virtual extremity, much like mirror therapy. Foot/Hand Exaggeration enables an experimental mode that affects the movement gain of the virtual avatar's feet and hands (higher exaggeration results in the virtual avatar moving farther than the patient moved in the real world, and lower exaggeration results in the virtual avatar moving less than the patient moved in the real world).
