A wall of cubes will be initialized as a curved surface with H by W size that each cube keeps the same distance to the user body. Each time, a cube will be chosen as the target and highlighted to indicate the user. The user should use a controller to touch the target cube and return to the original position. The new target will not appeart before the controller return back to the right position.
- average speed (per touch)
- upper body rotation degree (per touch)
- average angular speed/velocity (per touch)
- accuracy (the distance from the touch position to the cube center)
- total time of the game
