Abstract

A system includes a host computer configured to generate a graphical interface that includes a graphical object, obtain at least one spoken utterance, control an interaction of the graphical object within the graphical interface based on the spoken utterance, and generate an activating signal based on the spoken utterance. An interface device is configured to receive the spoken utterance, provide the spoken utterance to the host computer, and control the graphical object within the graphical interface based on the provided spoken utterance. The graphical object includes a graphical representation within the graphical interface. An actuator is disposed within a housing of the interface device, thereby protecting the actuator from contact by the user, and is configured to receive the activating signal from the host computer. The activating signal causes the actuator to impart a force via the housing.

Claims

1. A system, comprising:

a host computer configured to

generate a graphical interface that includes a graphical object,

obtain at least one spoken utterance,

control an interaction of the graphical object within the graphical interface based on the at least one spoken utterance, and

generate an activating signal based on the at least one spoken utterance;

an interface device configured to receive the at least one spoken utterance, provide the at least one spoken utterance to the host computer, and control the graphical object within the graphical interface based on the provided at least one spoken utterance, wherein the graphical object comprises a graphical representation within the graphical interface; and

an actuator disposed within a housing of the interface device, thereby protecting the actuator from contact by the user, the actuator configured to receive the activating signal from the host computer, wherein the activating signal causes the actuator to impart a force via the housing.

2. The system of claim 1, further comprising:

a second interface device configured to be operated by a second user; and

a second actuator disposed within a housing of the second interface device, thereby protecting the second actuator from contact by the second user, the second interface device configured to receive the activating signal from the host computer, wherein the activating signal causes the second actuator to impart a force to the second user.

3. The system of claim 1, wherein the actuator includes a moving portion that causes the force, wherein the moving portion is protected from contact by the user.

4. The system of claim 1, wherein the interface device further comprises:

a fastener configured to fasten the interface device to the user.

5. The system of claim 1, wherein the interface device comprises a handheld interface device.

6. The system of claim 1, wherein the activating signal causes the actuator to impart the force that varies by frequency.

7. The system of claim 1, wherein the graphical interface includes a second graphical object and wherein the interaction is between the graphical object and the second graphical object.

8. The system of claim 7, wherein the imparted force varies based on a virtual pressure applied to the second graphical object.

9. The system of claim 1, wherein the actuator comprises a rotating mass actuator having a shaft and an eccentric mass coupled to the shaft, wherein the rotating mass actuator produces the force by the mass rotating about the shaft around an axis of rotation, wherein a center of mass of the eccentric mass is offset from the axis of rotation thereby causing the force when the eccentric mass rotates about the shaft.

10. The system of claim 1, wherein the actuator comprises a linear actuator.

11. The system of claim 1, wherein the force comprises a varying amplitude over a duration of the force.

12. The system of claim 1, wherein the activating signal causes the actuator to output the force as a series of pulses.

13. The system of claim 1, wherein the force produces a tactile sensation.

14. The system of claim 1, wherein the host computer is configured to generate the activating signal based further on one or more states of the graphical object, the one or more states comprising a position, a velocity, or an acceleration of the graphical object within the graphical interface.

15. The system of claim 1, wherein the activating signal causes the actuator to impart one or more of visual, auditory, taste, smell, or temperature cues to the user.

16. The system of claim 1, wherein the housing is mounted onto a sensing instrument, the sensing instrument comprising one or more sensors that measure one or more physical conditions of the user.

17. A tangible computer-readable storage medium including instructions configuring a machine, the instructions when executed configuring the machine to perform a method, the method comprising:

displaying a graphical interface by a host computer, the graphical interface including a graphical object;

receiving a signal representative of at least one spoken utterance from an interface device configured to control the graphical object in the graphical interface, wherein the graphical object comprises a graphical representation of at least a portion of a body of a user;

controlling an interaction of the graphical object within the graphical interface based on the signal representative of the at least one spoken utterance;

generating an activating signal based on the signal representative of the at least one spoken utterance; and

transmitting the activating signal to the interface device based on an interaction related to the graphical object in the graphical interface,

wherein the activating signal causes an actuator disposed within a housing of the interface device, thereby protecting the actuator from contact by the user, to output a force via the housing.

18. The tangible computer readable storage medium of claim 17, the graphical interface including a second graphical object, wherein the interaction comprises a collision between the graphical object and the second graphical object in the graphical interface.

19. The tangible computer readable storage medium of claim 17, wherein the actuator comprises a rotating mass actuator having a shaft and an eccentric mass coupled to the shaft, wherein the mass is rotated about the shaft around an axis of rotation to produce the force, wherein a center of mass of the eccentric mass is offset from the axis of rotation thereby causing the force when the eccentric mass rotates about the shaft.

20. The tangible computer readable storage medium of claim 17, wherein the force produces a tactile sensation.

21. The tangible computer readable storage medium of claim 17, wherein the force varies by amplitude over a duration of the force.

22. The tangible computer readable storage medium of claim 17, wherein the activating signal causes the actuator to output the force as a series of pulses.

23. An apparatus comprising:

an input configured to receive at least one spoken utterance to control a graphical object within a graphical interface, wherein the graphical object comprises a graphical representation of at least a portion of a body of a user;

at least one processor configured to;

generate a signal based on the at least one spoken utterance,

cause the signal to be transmitted to a host computer,

receive from the host computer an activating signal based on the generated signal; and

an actuator configured to output a force based on the activating signal in coordination with the graphical interface, wherein the actuator is disposed within the housing, thereby protecting the actuator from contact by the user.

24. A computing device, comprising:

one or more processors configured to

generate a graphical interface, wherein the graphical interface comprises at least one graphical object;

obtain at least one spoken utterance from an interface device;

control the at least one graphical object based on the at least one spoken utterance from the interface device;
