Abstract
A tactile generator comprises an eccentric mass that imparts a vibration as it rotates about a rotational axis. The mass is radially movable with respect to the rotational axis such that the distance between the mass and the axis is variable. Varying the distance of the mass from the axis varies the amount of vibration generated when the mass is rotated. The amount of vibration may be controlled responsive to a detected level of ambient noise.
