Abstract

A haptic feedback control device, such as a handheld remote control or handheld game controller, for controlling a graphical object within a graphical display and for outputting forces to a user. A housing includes a button, wherein the user engages the button with a finger. The button is depressible along a degree of freedom by the user. An actuator applies forces to the user through the button along the degree of freedom. A sensor detects displacement of the button along the degree of freedom when the button is depressed by the user. A process, local to the device, controls the actuator to generate the forces upon the button in the degree of freedom to provide a tactile sensation to the user contacting the button.

Claims

1. A device, comprising:

a housing having a fixed portion and a moveable portion, the moveable portion configured to move laterally with respect to the fixed portion;

a coupling member coupled to the moveable portion and the fixed portion; and

an actuator coupled to the coupling member, the actuator configured to output haptic feedback to the moveable portion of the housing via the coupling member.

2. The device of claim 1, wherein the coupling member is a flexure member.

3. The device of claim 1, wherein the haptic feedback is output based on an oscillation of a shaft of the actuator.

4. The device of claim 1, wherein the coupling member includes a first flexure member and a second flexure member, the first flexure member and the second flexure member being coupled between the moveable portion and the fixed portion, the actuator being configured to output the haptic feedback via at least one of the flexure members.

5. The device of claim 1, further comprising a manipulandum disposed adjacent to the moveable portion, the haptic feedback being imparted to the manipulandum.

6. The device of claim 1, further comprising a manipulandum disposed adjacent to the moveable portion, the haptic feedback being imparted to the manipulandum, the manipulandum is fixed in position with reference to the moveable portion.

7. The device of claim 1, further comprising a button disposed adjacent to the moveable portion, the haptic feedback being imparted to the button.

8. The device of claim 1, further comprising a button movable in a degree of freedom disposed adjacent to the moveable portion, the haptic feedback being imparted to the button in the degree of freedom.

9. The device of claim 1, further comprising a sensor coupled to the housing, the sensor being configured to detect a movement of the moveable portion with respect to the fixed portion.

10. A method, comprising:

sending a control signal to a processor associated with a graphical display, the control signal based on a position of a button in a degree of freedom;

receiving a haptic feedback signal from the processor, the haptic feedback signal being based on the control signal;

outputting a first haptic feedback to the button in the degree of freedom, and

outputting a second haptic feedback to a moveable portion of a housing in which the button is disposed.

11. The method of claim 10, wherein the first haptic feedback is associated with an interaction of a controlled object with a first simulated object in the graphical environment, the second haptic feedback being associated with an interaction of the controlled object with a second simulated object in the graphical environment.

12. A device, comprising:

a button depressible along a degree of freedom;

an actuator coupled to the button;

a sensor configured to detect a displacement of the button along the degree of freedom; and
