Apparatus and method for providing detent-like tactile feedback

Apparatus for providing detent-like tactile feedback to a user, comprises a shell (24), a rolling member (20) rotatably provided within the shell, a motion sensing mechanism (23) for determining displacement of the rolling member when the rolling member is rotated, at least one actuator (22) situated within the shell, and at least one brake member (21) provided with respect to the at least one actuator, the at least one actuator retracting and extending the at least one brake member to selectively influence the rotation of the rolling member based on feedback from the embodying system.
