SYSTEM AND METHOD FOR POINT, SELECT AND TRANSFER HAND GESTURE BASED USER INTERFACE
First Claim
1. A computer implemented method for a point, select and transfer hand gesture based user interface, comprising:
- capturing a depth image of a hand gesture using an in-front camera substantially on a frame by frame basis within a predefined interaction volume and wherein the in-front camera is substantially disposed around a display device and wherein the display device is designed to display a plurality of select options;
finding a nearest point of the hand gesture to a display screen of the display device using a substantially nearest depth value in the captured depth image for each frame;
performing an image-to-screen mapping of the captured depth image and the found nearest point to the display screen upon validating the found nearest point as associated with the hand for each frame; and
pointing and selecting one of the plurality of displayed select options on the display screen of the display device when the substantially nearest depth value is within one or more predetermined threshold values or ranges, and based on the outcome of the image-to-screen mapping.

Abstract
A system and method for a point, select and transfer hand gesture based user interface is disclosed. In one embodiment, a depth image of a hand gesture is captured using an in-front camera substantially on a frame by frame basis within a predefined interaction volume. Also, a nearest point of the hand gesture to a display screen of a display device is found using a substantially nearest depth value in the captured depth image for each frame. Further, an image-to-screen mapping of the captured depth image and the found nearest point to the display screen is performed upon validating the found nearest point as associated with the hand for each frame. Moreover, one of select options displayed on the display screen is pointed and selected when the substantially nearest depth value is within one or more predetermined threshold ranges, and based on the outcome of the image-to-screen mapping.

14. A system for a point, select and transfer hand gesture based user interface, comprising:
-
a processor; a display device having a display screen and coupled to the processor, wherein the display device is configured to display a plurality of select options; an in-front camera disposed substantially around the display device; and memory operatively coupled to the processor, wherein the memory includes a point, select and transfer hand gesture based user interface module having instructions capable of; capturing a depth image of a hand gesture using the in-front camera substantially on a frame by frame basis within a predefined interaction volume and wherein the in-front camera is substantially disposed around a display device and wherein the display device is designed to display a plurality of select options; finding a nearest point of the hand gesture to a display screen of the display device using a substantially nearest depth value in the captured depth image for each frame; performing an image-to-screen mapping of the captured depth image and the found nearest point to the display screen upon validating the found nearest point as associated with the hand for each frame; and pointing and selecting one of the plurality of displayed select options on the display screen of the display device when the substantially nearest depth value is within one or more predetermined threshold values or ranges, and based on the outcome of the image-to-screen mapping. - View Dependent Claims (15)
