A 2006 Wii Remote as the input device, and motion tennis rebuilt in Unity.

PROBLEM
An accelerometer reports raw three-axis readings, not "a swing." Making the ball answer to the hand means turning that signal into a meaningful velocity vector yourself.
APPROACH
Reading the Wii Remote’s accelerometer over the Bluetooth API, mapping it to swing velocity, and implementing real-time ball physics in Unity.
RESULT
1:1 real-time motion tracking — the force and direction of a swing land directly on the ball.
