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 first moveable portion defined as a first partial outer surface of the housing and a second moveable portion defined as a partial second outer surface of the housing located opposite to the first partial outer surface, the housing to be grasped by a user and the fixed portion moveable in three dimensions with respect to ground during operation, the first and second moveable portions including pads configured to be selectively moved toward and away each other;

a sensor coupled to the housing and configured to measure positional values of the fixed portion when moved in the three dimensions;

a flexure member coupled to at least the first moveable portion and the fixed portion, wherein the flexure member is configured to allow selective movement of the first moveable portion with respect to the fixed portion; and

an actuator coupled to the flexure member, the actuator configured to output haptic feedback to the first and second moveable portions of the housing via the flexure member.

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

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

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

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

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

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

8. The device of claim 7, further comprising a second sensor coupled to the housing, the sensor being configured to detect a movement of the button along the degree of freedom when depressed.

9. The device of claim 1, wherein the housing is adapted to be coupled to a linkage mechanism coupled to ground.

10. The device of claim 1, wherein the fixed portion is coupled to a linkage mechanism located externally thereto, wherein the fixed portion is at least rotatable with respect to the linkage mechanism.
