Point Tracking screen
Initialization: While pointing the Fusion module at the center of the screen, press “P” or
click the right button on the module. This starts the Point Tracking screen and establishes
the relationship between the orientation of the SpacePoint module and the cursor position.
The cursor will now track the orientation of the SpacePoint module. Point the module to
the left or right, and the cursor will move to the left or right. This will happen with low
latency and high precision. If the Fusion is pointed so the cursor goes off screen, SpacePoint
technology continues tracking the absolute orientation of the module so when you later
point the Fusion at the center of the screen, the cursor returns to the center of the screen.
2.4 Mallet Game
In the Mallet Game a player controls a mallet to hit as many robots as possible. This game
highlights the ability of SpacePoint technology to maintain accurate tracking over a long
duration without requiring interruptions for calibration, even when movements are harsh
and sudden. The types of movements required to hit the robots normally would create
errors with typical controllers that utilize accelerometers and gyroscopes. The addition of
the reference magnetic sensor compensates for gyro drift to result in game play that is
uninterrupted and withstands rapid and harsh movement.
