Here’s what Sony says about the Move.

“The Move motion controller delivers unmatched accuracy through its advanced motion sensors, including a three-axis gyroscope, a three-axis accelerometer, and a terrestrial magnetic field sensor, as well as a colour-changing sphere that is tracked by PlayStation Eye camera,”

“Through the PlayStation Move system, both fast and subtle motion can be detected, whether the user is swinging a tennis racket or painting with a brush. The system can even capture the player’s voice or image, enabling augmented reality experiences.”
