Abstract: A method includes receiving a sequence of three-dimensional (3D) maps of at least a part of a body of a user of a computerized system and extracting, from the 3D map, 3D coordinates of a head of the user. Based on the 3D coordinates of the head, a direction of a gaze performed by the user and an interactive item presented in the direction of the gaze on a display coupled to the computerized system are identified. An indication is extracted from the 3D maps an indication that the user is moving a limb of the body in a specific direction, and the identified interactive item is repositioned on the display responsively to the indication.

Abstract: A method, including presenting, by a computer, multiple interactive items on a display coupled to the computer, receiving an input indicating a direction of a gaze of a user of the computer. In response to the gaze direction, one of the multiple interactive items is selected, and subsequent to the one of the interactive items being selected, a sequence of three-dimensional (3D) maps is received containing at least a hand of the user. The 3D maps are analyzed to detect a gesture performed by the user, and an operation is performed on the selected interactive item in response to the gesture.

Abstract: A method includes receiving and segmenting a first sequence of three-dimensional (3D) maps over time of at least a part of a body of a user of a computerized system in order to extract 3D coordinates of a first point and a second point of the user, the 3D maps indicating a motion of the second point with respect to a display coupled to the computerized system. A line segment that intersects the first point and the second point is calculated, and a target point is identified where the line segment intersects the display. An interactive item presented on the display in proximity to the target point is engaged.
