Abstract

The present invention relates to a system (200) for rendering a three-dimensional object, comprising an input device (202, 302), a processor (204, 306), and a picture reproduction device (206, 308). The input device (202, 302) comprises an image sensor (303) for capturing images of a first hand of a user, and is arranged to communicate the image to the processor (204, 306). The processor (204, 306) is arranged to process the images to determine movements of at least a part of the first hand for generating a control signal. The picture reproduction device (206, 308) is arranged to display 3D data of the three-dimensional object according to the control signal. While capturing images of the first hand of the user, the input device (202, 302) is adapted to be held in a second hand of the user during operation. A method complying with the features of the system (200) is also disclosed.

Claims

1. A system for rendering a three-dimensional object, comprising an input device (202, 302), a processor (204, 306), and a picture reproduction device (206, 308), wherein the input device (202, 302) comprises an image sensor (303) for capturing images of a first hand of a user, and is arranged to communicate said image to the processor (204, 306);

the processor (204, 306) is arranged to process said images to determine movements of at least a part of said first hand for generating a control signal; and

the picture reproduction device (206, 308) is arranged to display 3D data of said three-dimensional object according to said control signal,

wherein said input device (202, 302) is adapted to be held in a second hand of the user during operation.

2. The system according to claim 1, wherein said control signal also is dependent on a determined distance between the input device (202, 302) and said first hand.

3. The system according to claim 1, wherein said control signal also is dependent on a determined orientation of the input device (202, 302).

4. The system according to claim 1, wherein said control signal also is dependant on a determined gesture of said first hand.

5. The system according to claim 1, wherein magnification, brightness, contrast, hue, perspective, or view, or any combination thereof, of said 3D data is controlled by said control signal.

6. The system according to claim 1, wherein communication between said input device (202, 302) and said processor (204, 306) is wireless.

7. A method of rendering a three-dimensional object, comprising the steps of:

capturing a plurality of images of a first hand by operating an image capturing input device (202, 302) by a second hand;

processing said images to determine movements of at least a part of said first hand; and

displaying 3D data of said three-dimensional object, wherein a view of said 3D data is dependent on said determined movements.

8. The method according to claim 7, further comprising the step of determining a distance between the input device (202, 302) and said first hand, wherein said view is dependent on said distance.

9. The method according to claims 7, further comprising the step of determining an orientation of the input device (202, 302), wherein said view is dependent on said orientation.

10. The method according to claim 7, further comprising the step of determining a gesture of said first hand, wherein said view is dependent on said gesture.

11. The method according to claim 7, further comprising the step of controlling magnification, brightness, contrast, hue, perspective, or any combination thereof, of said view dependant on a determined distance, orientation, or gesture, or any combination thereof.
