Abstract

Depth-image analysis is performed with a device that analyzes a human target within an observed scene by capturing depth-images that include depth information from the observed scene. The human target is modeled with a virtual skeleton including a plurality of joints. The virtual skeleton is used as an input for controlling a driving simulation.

Claims

1. A data holding device holding instructions executable by a logic subsystem to:

render a driving game for display on a display device;

receive a virtual skeleton including a plurality of joints, the plurality of joints including a left hand joint and a right hand joint, the virtual skeleton providing a machine readable representation of a human target observed with a three-dimensional depth camera;

translate an angle between a reference line and a line connecting the left hand joint and the right hand joint into a gestured steering angle control; and

steer a virtual vehicle of the driving game in proportion to the gestured steering angle control.

2. The data holding device of claim 1, further holding instructions executable by the logic subsystem to also steer the virtual vehicle in proportion to an artificial intelligence recommended control such that the virtual vehicle turns in proportion to a blend of both the gestured steering angle control and the artificial intelligence recommended control.

3. The data holding device of claim 2, wherein a relative percentage of the gestured steering angle control and the artificial intelligence recommended control is dynamically set according to one or more changeable game parameters.

4. The data holding device of claim 3, wherein the one or more changeable game parameters includes a speed of the virtual vehicle, and wherein the relative percentage of the gestured steering angle control decreases as the speed of the virtual vehicle increases.

5. The data holding device of claim 3, wherein the one or more changeable game parameters includes a turning radius of a virtual track, and wherein the relative percentage of the gestured steering angle control decreases as the turning radius of the virtual track increases.

6. The data holding device of claim 3, wherein the one or more changeable game parameters includes a deviation from a recommended path, and wherein the relative percentage of the gestured steering angle control decreases as the deviation from the recommended path increases.

7. The data holding device of claim 1, further holding instructions executable by the logic subsystem to:

translate a position of a left foot joint of the virtual skeleton relative to a position of a right foot joint of the virtual skeleton into a gestured acceleration control; and

accelerate the virtual vehicle in proportion to the gestured acceleration control.

8. The data holding device of claim 7, wherein a right foot joint in front of the left foot joint is translated as a positive acceleration, and a right foot joint behind the left foot joint is translated as a negative acceleration.

9. The data holding device of claim 1, further holding instructions executable by the logic subsystem to:

translate a distance of the left hand joint and the right hand joint away from one or more torso joints into a gestured acceleration control; and

accelerate the virtual vehicle in proportion to the gestured acceleration control.

10. The data holding device of claim 9, wherein positive acceleration increases in proportion to the distance of the left hand joint and the right hand joint away from the one or more torso joints.

11. The data holding device of claim 1, further holding instructions executable by the logic subsystem to:

translate a sudden movement of a hand joint from near one or more torso joints to a position away from the one or more torso joints into a gestured turbo boost control; and

12. The data holding device of claim 1, further holding instructions executable by the logic subsystem to:

translate a movement of a hand joint near a hip joint into a gestured gear shift control; and

changing a gear of the virtual vehicle in response to the gestured gear shift control.

13. The data holding device of claim 12, wherein the gear is increased responsive to a forward movement of the hand joint and the gear is decreased responsive to a backwards movement of the hand joint.

14. The data holding device of claim 1, further holding instructions executable by the logic subsystem to:

translate a posture of one or more hands modeled by corresponding hand joints of the virtual skeleton into a gestured gear shift control; and

changing a gear of the virtual vehicle in response to the gestured gear shift control.

15. The data holding device of claim 14, wherein the gear is increased responsive to an opening and closing of a right hand and the gear is decreased responsive to an opening and closing of a left hand.

16. The data holding device of claim 1, wherein the angle between a reference line and the line connecting the left, hand joint and the right hand joint is translated into a gestured steering angle control only if the right hand joint and the left hand joint are outstretched in front of one or more torso joints.
