Milestone 1
The controller announces an event.
What players noticed
An impact could cross the screen and arrive in the player’s hands.
The mechanism
A small electric motor spins an off-center weight. Because the mass is unbalanced, the rotating force shakes the controller. Faster rotation changes the character of the vibration.
What remained
A spinning mass takes time to accelerate and stop. It is expressive in intensity, but imprecise in timing and texture.
