Abstract

A system including a display, a sensor and a controller. The sensor can detect an object and generate data related to the object. The controller can determine a first pose of the object from the data and display a first representative image on the display. The controller can determine a second pose of the object and display a second representative image on the display, wherein the second representative image is associated with a displayed element.

Claims

1. A system comprising:

a display;

a sensor to detect an object and generate data related to the object; and

a controller to determine a first pose of the object from the data and display a first representative image on the display and to determine a second pose of the object and display a second representative image on the display, wherein the second representative image is associated with a displayed element.

2. The system of claim 1, wherein the controller determines if the object is within a first volume from the display before displaying the first or second representative image on the panel.

3. The system of claim 1, wherein the first representative image is one of radially symmetric or a shape of a hand.

4. The system of claim 1, wherein the first representative image has dimensions that are determined by the distance of the object from the display determined by the controller from the data.

5. The system of claim 1, wherein the first representative image and the second representative image are repositioned on the display if the data indicates the object detected changed positions.

6. The system of claim 1, further comprising a storage including data accessed by the controller to determine if the first pose is one of a hand with fingers extended and a hand with fingers touching.

7. The system of claim 1, further comprising an enclosure including the display and the sensor.

8. A method, comprising.

detecting a position of an object with a sensor;

displaying on a display a first representative image on the display indicating a first pose of the object on the two dimensional display if the object is within a volume from the display; and

displaying a second representative image representing a second pose of the object.

9. The method of claim 8, further comprising associating the position of the second representative image with a displayed element on the display.

10. The method of claim 9, further comprising detecting an orientation, distance from the display, and position while in a second pose of the object and rotate, enlarge, or move the displayed element respectively.

11. The method of claim 8, further comprising adjusting the size of the first or second representative image based on the distance from the display of the object.

12. The method of claim 8, further comprising activating a displayed element if the sensor detects an object within a touch distance from the display.

13. A computer readable medium comprising instructions that if executed cause a computer to:

detect a position of an object with a sensor;

display on a display a first representative image on the display indicating a first pose of the object on the two dimensional display if the object is within a volume from the display; and

display a second representative image representing a second pose of the object on the two dimensional display if the object is within a volume from the display.

14. The computer readable medium of claim 13 further comprising instructions to associate a second pose with a displayed element.

15. The computer readable medium of claim 13 further comprising instructions to move a displayed element that is connected to the second representative image if the second representative image is moved in one of an X, Y or Z direction according to the position of the object.
