1. An apparatus, comprising:
- a manipulandum;
a sensor configured to sense movement of the manipulandum between a first position and a second position of a detent, wherein the sensor is configured to output a positional signal when the manipulandum is sensed moving from the first position to the second position; and
an actuator configured to output a first haptic feedback force to the manipulandum in response to the positional signal indicating the manipulandum moving between the first position and the second position, wherein the first haptic feedback force corresponds to a position based force signal, the actuator configured to output a second haptic feedback force to the manipulandum only once in response to the positional signal indicating the manipulandum at a threshold position between the first and second positions, the second haptic feedback force including the position based force signal and a predetermined time-based force signal.

Abstract
A manipulandum includes a sensor and an actuator. The sensor is configured to output a position signal when the manipulandum is moved from the first position to the second position. Additionally, the actuator is configured to output haptic feedback having a position-based component and a predetermined time-based component.

9. A method for outputting haptic sensation, comprising:
-
sensing movement of a manipulandum between a first position and a second position of a detent; outputting a position-based force signal to an actuator coupled to the manipulandum, the position-based force signal associated with the manipulandum being sensed from the first position to the second position; outputting a first haptic feedback force via the actuator upon receiving the position-based force signal when the manipulandum is moving between the first and second positions; and outputting a second haptic feedback force via the actuator only once upon sensing the manipulandum at a threshold position between the first and second positions, the second haptic feedback including a predetermined time-based force signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for outputting haptic sensation, comprising:
-
sensing movement of a rotatable knob between a first position and a second position of a detent; outputting a position-based force signal to an actuator coupled to the knob, the position-based force signal associated with the manipulandum being sensed from the first position to the second position; outputting a first haptic feedback force via the actuator upon receiving the position-based force signal when the knob is rotating between the first and second positions; and outputting a second haptic feedback force via the actuator only once upon sensing the knob at a threshold position between the first and second positions, the second haptic feedback including a predetermined time-based force signal.
