Abstract

A method, including receiving, by a computer, a sequence of three-dimensional maps containing at least a hand of a user of the computer, and identifying, in the maps, a device coupled to the computer. The maps are analyzed to detect a gesture performed by the user toward the device, and the device is actuated responsively to the gesture.

Claims

1. A method for interaction with a computer, the method comprising:

receiving, by a computer, a sequence of three-dimensional maps containing at least an arm, including an elbow and a hand, of a user of the computer;

identifying, in the maps, a controlled device that is coupled to the computer;

analyzing the maps to detect a gesture performed by the arm toward the controlled device; and

actuating the controlled device responsively to the gesture on condition that the elbow is extended in the gesture at an angle no less than a predefined angular threshold.

2. The method according to claim 1, wherein the gesture is selected from a list consisting of a pointing gesture, a grab gesture and a release gesture.

3. The method according to claim 1, wherein analyzing the maps comprises defining a pyramid shaped region having an apex meeting the user and a base encompassing the device, and defining an interaction region within the pyramid shaped region,

wherein the detected gesture comprises the user positioning the hand within the interaction region and moving the hand toward the controlled device.

4. The method according to claim 1, wherein the controlled device is actuated only when the elbow has been extended in the gesture for at least a predefined minimum time period.

5. The method according to claim 1, and comprising receiving a vocal command from the user, wherein the controlled device is actuated in response to the gesture and the vocal command.

6. The method according to claim 1, and comprising detecting, in the maps, a gaze direction of the user, wherein the controlled device is actuated in response to the gesture and the gaze direction.

7. The method according to claim 1, and comprising communicating between the controlled device and a further device upon detecting, in the maps, a subsequent gesture directed toward the further device.

8. An apparatus, comprising:

a three-dimensional sensing device; and

a computer configured to receive from the three-dimensional sensing device a sequence of three-dimensional maps containing at least an arm, including an elbow and a hand, of a user of the computer, to identify, in the maps, a controlled device that is coupled to the computer, to analyze the maps to detect a gesture performed by the arm toward the controlled device, and to actuate the controlled device responsively to the gesture on condition that the elbow is extended in the gesture at an angle no less than a predefined angular threshold.

9. The apparatus according to claim 8, wherein the gesture from a list consisting of a pointing gesture, a grab gesture and a release gesture.

10. The apparatus according to claim 8, wherein the computer is configured to analyze the maps by defining a pyramid shaped region having an apex that meets the user and a base encompassing the entity and defining an interaction region within the pyramid shaped region, and

wherein the detected gesture comprises the user positioning the hand within the interaction region and moving the hand toward the controlled device.

11. The apparatus according to claim 8, wherein the computer is configured to actuate the controlled device only when the elbow has been extended in the gesture for at least a predefined minimum time period.

12. The apparatus according to claim 8, wherein the computer is configured to receive a vocal command from the user, and to actuate the controlled device in response to the gesture and the vocal command.

13. The apparatus according to claim 8, wherein the computer is configured to detect, in the maps, a gaze direction of the user, and to actuate the controlled device in response to the gesture and the gaze direction.

14. The apparatus according to claim 8, wherein the computer is configured to convey communication between the controlled device and a further device upon detecting, in the maps, a subsequent gesture directed toward the further entity.

15. A computer software product comprising a non-transitory computer-readable medium, in which program instructions are stored, which instructions, when read by a computer, cause the computer to receive a sequence of three-dimensional maps containing at least an arm, including an elbow and a hand, of a user of the computer, to identify, in the maps, a controlled device that is coupled to the computer, to analyze the maps to detect a gesture performed by the arm toward the controlled device, and to actuate the controlled device responsively to the gesture on condition that the elbow is extended in the gesture at an angle no less than a predefined angular threshold.

16. The product according to claim 15, wherein the gesture from a list consisting of a pointing gesture, a grab gesture and a release gesture.

17. The product according to claim 15, wherein the instructions cause the computer to analyze the maps by defining a pyramid shaped region having an apex that meets the user and a base encompassing the controlled device and to define an interaction region within the pyramid shaped region, wherein the detected gesture comprises the user positioning the hand within the interaction region and moving the hand toward the controlled device.

18. The product according to claim 15, wherein the instructions cause the computer to actuate the controlled device only when the elbow has been extended in the gesture for at least a predefined minimum time period.

19. The product according to claim 15, wherein the instructions cause the computer to receive a vocal command from the user, and to actuate the controlled device in response to the gesture and the vocal command.

20. The product according to claim 15, wherein the instructions cause the computer to detect, in the maps, a gaze direction of the user, and to actuate the controlled device in response to the gesture and the gaze direction.
