Patent Images
1. A user interface method, comprising:
- presenting by a computer executing a user interface, multiple interactive items on a display;
capturing a first sequence of images indicating a position in space of a hand of a user in proximity to the display;
responsively to the position, associating a given interactive item with the hand,wherein associating the given interactive item comprises detecting, in the first sequence of images, a predetermined gesture of the hand, wherein the predetermined gesture comprises closing at least some of the fingers of the hand, and initiating association of the given interactive item with the hand responsively to the gesture;
after associating the item, capturing a second sequence of images indicating a movement of the hand;
responsively to the movement, changing a size of the one of the items on the display; and
releasing the association of the given interactive item from the hand upon detecting that the fingers have opened.

Abstract
A user interface method, including presenting by a computer executing a user interface, multiple interactive items on a display. A first sequence of images is captured indicating a position in space of a hand of a user in proximity to the display, and responsively to the position, one of the interactive items is associated with the hand. After associating the item, a second sequence of images is captured indicating a movement of the hand, and responsively to the movement, a size of the one of the items is changed on the display.

8. A user interface method, comprising:
-
presenting by a computer executing a user interface, multiple interactive items on a display; capturing a first sequence of images indicating a position in space of a hand of a user in proximity to the display; responsively to the position, associating a given interactive item with the hand, wherein associating the given interactive item comprises detecting, in the first sequence of images, a predetermined gesture of the hand, and initiating association of the given interactive item with the hand responsively to the gesture; after associating the item, capturing a second sequence of images indicating a movement of the hand; and responsively to the movement, changing a size of the one of the items on the display, wherein associating the given interactive item comprises detecting, in the first sequence of images, a transverse motion of the hand while the hand maintains the gesture, and associating a different one of the interactive items with the hand responsively to the transverse motion. - View Dependent Claims (9, 10, 11)

19. An apparatus, comprising:
-
a sensing device; and a computer executing a user interface and configured to present multiple interactive items on a display coupled to the computer, to capture a first sequence of images indicating a position in space of a hand of a user in proximity to the display, to associate, responsively to the position, a given one of the interactive items with the hand, to capture, after associating the given interactive item, a second sequence of images indicating a movement of the hand and to change a size of, responsively to the movement, the given interactive item on the display, wherein the computer is configured to associate the given interactive item by detecting, in the first sequence of images, a predetermined gesture of the hand, and initiating association of the given interactive item with the hand responsively to the gesture, and to detect, in the first sequence of images, a transverse motion of the hand while the hand maintains the gesture, and to associate a different one of the interactive items with the hand responsively to the transverse motion. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 28, 29, 30, 31, 32, 33, 34, 35, 36)

27. An apparatus, comprising:
-
a sensing device; and a computer executing a user interface and configured to present multiple interactive items on a display coupled to the computer, to capture a first sequence of images indicating a position in space of a hand of a user in proximity to the display, to associate, responsively to the position, a given one of the interactive items with the hand, to capture, after associating the given interactive item, a second sequence of images indicating a movement of the hand and to change a size of, responsively to the movement, the given interactive item on the display, wherein the computer is configured to associate the given interactive item by detecting, in the first sequence of images, a predetermined gesture of the hand comprising closing at least some of the fingers of the hand, and initiating association of the given interactive item with the hand responsively to the gesture, and to release the association of the given interactive item from the hand upon detecting that the fingers have opened.

37. A computer software product comprising a non-transitory computer-readable medium, in which program instructions are stored, which instructions, when read by a computer executing a user interface, cause the computer to present multiple interactive items on a display, to capture a first sequence of images indicating a position in space of a hand of a user in proximity to the display, to associate, responsively to the position, a given one of the interactive items with the hand, to capture, after associating the given interactive item, a second sequence of images indicating a movement of the hand, and to change, responsively to the movement, a size of the given interactive item on the display,
wherein the instructions cause the computer to associate the given interactive item by detecting, in the first sequence of images, a predetermined gesture of the hand comprising closing at least some of the fingers of the hand, and initiating association of the given interactive item with the hand responsively to the gesture, and to release the association of the given interactive item from the hand upon detecting that the fingers have opened.
