Abstract

A system and method for implementing a remote controlled user interface using close range object tracking are described. Close range depth images of a user'"'"'s hands and fingers or other objects are acquired using a depth sensor. Using depth image data obtained from the depth sensor, movements of the user'"'"'s hands and fingers or other objects are identified and tracked. The tracking data is transmitted to an external control device, thus permitting the user to interact with an object displayed on a screen controlled by the external control device, through movements of the user'"'"'s hands and fingers.

Claims

1. A method for controlling a user interface, the method comprising:

acquiring a first set of close range depth images of a part of a first user'"'"'s body with a first depth sensor, wherein the first depth sensor is coupled to a first remote control device;

identifying from the first set of depth images movement of the part of the first user'"'"'s body;

tracking the movement of the part of the first user'"'"'s body;

providing feedback on the tracked movement of the part of the first user'"'"'s body;

transmitting a first set of tracking data associated with the tracked movement of the part of the first user'"'"'s body to a controlled device, wherein the first set of tracking data is used to control the user interface for the controlled device.

2. The method of claim 1, wherein the feedback is provided from the first remote control device.

3. The method of claim 1, wherein the feedback is provided from the controlled device.

4. The method of claim 1, wherein providing feedback on the tracked movement comprises representing the tracked part of the first user'"'"'s body by a first object on a screen of the controlled device or the first remote control device.

5. The method of claim 4, wherein the identified movement of the part of the first user'"'"'s body corresponds to a select gesture, wherein the first object is used to select a second object on the screen of the controlled device or the first remote control device.

6. The method of claim 4, wherein the identified movement of the part of the first user'"'"'s body corresponds to a manipulate gesture, wherein the first object manipulates a second object on the screen of the controlled device or the first remote control device according to a predefined action associated with the manipulate gesture.

7. The method of claim 1, wherein the movement generates a force that interacts with objects on a screen of the controlled device or the first remote control device.

8. The method of claim 1, wherein the part of the first user'"'"'s body includes one or more fingers and each of the one or more fingers are represented as one or more separate first objects on a screen of the controlled device or the first remote control device, and each of the separate first objects interact with other objects on the screen.

9. The method of claim 1, further comprising:

acquiring a second set of close range depth images of a part of a second user'"'"'s body with a second depth sensor, wherein the second depth sensor is coupled to a second remote control device;

identifying from the second set of depth images movement of the part of the second user'"'"'s body;

tracking the movement of the part of the second user'"'"'s body;

providing feedback on the tracked movement of the part of the second user'"'"'s body;

transmitting a second set of tracking data associated with the tracked movement of the part of the second user'"'"'s body to the controlled device, wherein the second set of tracking data is further used to control the user interface for the controlled device.

10. The method of claim 9, wherein the feedback on the tracked movement of the part of the first user'"'"'s body and the feedback on the tracked movement of the part of the second user'"'"'s body are provided from the controlled device.

11. The method of claim 9, wherein the feedback on the tracked movement of the part of the first user'"'"'s body is provided from the first remote control device, and the feedback on the tracked movement of the part of the second user'"'"'s body is provided from the second remote control device.

12. A system for controlling a user interface, the system comprising:

a remote control device communicatively coupled to a controlled device, wherein the remote control device comprises;

a depth sensor configured to acquire depth images of a user'"'"'s movements;

an output module configured to transmit information to the controlled device, wherein the information includes data generated by the depth sensor;

the controlled device, wherein the controlled device comprises;

an input module configured to receive the information from the remote control device and convert the information into signals;

a device software module configured to receive the signals from the input module to control the user interface for the controlled device.

13. The system of claim 12, wherein the user'"'"'s movements are performed by a part of the user'"'"'s body.

14. The system of claim 12, wherein the remote control device further comprises:

a tracking module configured to track the user'"'"'s movements, wherein the information transmitted by the output module further includes the tracked user'"'"'s movements;

a feedback module configured to provide feedback to the user pertaining to the user'"'"'s tracked movements.

15. The system of claim 14, wherein the remote control device further comprises:

a gesture recognition module configured to identify the tracked user'"'"'s movements as one or more gestures,

wherein the information transmitted by the output module further includes the identified one or more gestures.

16. The system of claim 12,

wherein the remote control device further comprises:

a tracking module configured to track the user'"'"'s movements, wherein the information transmitted by the output module further includes the tracked user'"'"'s movements; and

further wherein the controlled device further comprises;

a feedback module configured to provide feedback to the user pertaining to the user'"'"'s tracked movements.

17. The system of claim 16, wherein the remote control device further comprises:

a gesture recognition module configured to identify the tracked user'"'"'s movements as one or more gestures,

wherein the information transmitted by the output module further includes the identified one or more gestures.

18. The system of claim 12, wherein the controlled device further comprises:

a tracking module configured to track the user'"'"'s movements, wherein the device software module further uses the tracked user'"'"'s movements to control the user interface for the controlled device;

a feedback module configured to provide feedback to the user pertaining to the user'"'"'s tracked movements.

19. The system of claim 18, wherein the controlled device further comprises:

a gesture recognition module configured to identify the user'"'"'s movements as one or more gestures, wherein the device software module further uses the identified one or more gestures to control the user interface for the controlled device.

20. A system for controlling a user interface, the system comprising:

means for acquiring close range depth images of a part of a user'"'"'s body with a depth sensor, wherein the depth sensor is coupled to a remote control device;

means for identifying from the depth images movement of the part of the user'"'"'s body;

means for tracking the movement of the part of the user'"'"'s body;

means for providing feedback on the tracked movement to the user;

means for transmitting tracking data to a controlled device, wherein the tracking data are used to control the user interface for the controlled device.
