1. A method, comprising:
- receiving a first sequence of three-dimensional (3D) maps over time of at least a part of a hand of a user of a computerized system;
segmenting the 3D maps in order to extract 3D coordinates of a first point located on a knuckle of the finger on the hand and a second point at a tip of the finger;
calculating a line segment that extends through the first point and the second point to a display that is coupled to the computerized system;
identifying a target point where the line segment intersects the display; and
in response to a motion of the hand indicated by the 3D maps, engaging an interactive item presented on the display in proximity to the target point.

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.

12. An apparatus, comprising:
-
a display; and a computer coupled to the display and configured to receive and segment a first sequence of three-dimensional (3D) maps over time of at least a part of a hand of a user of a computerized system in order to extract 3D coordinates of a first point located on a knuckle of the finger on the hand and a second point at a tip of the finger, to calculate a line segment that extends through the first point and the second point to the display, to identify a target point where the line segment intersects the display, and in response to a motion of the hand indicated by the 3D maps, to engage an interactive item presented on the display in proximity to the target point. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A computer software product comprising a non-transitory computer-readable medium, in which program instructions are stored, which instructions, when read by a computer, which is coupled to a display, cause the computer to receive and segment a first sequence of three-dimensional (3D) maps over time of at least a part of a hand of a user of a computerized system in order to extract 3D coordinates of a first point located on a knuckle of the finger on the hand and a second point at a tip of the finger, to calculate a line segment that extends through the first point and the second point to the display, to identify a target point where the line segment intersects the display, and in response to a motion of the hand indicated by the 3D maps, to engage an interactive item presented on the display in proximity to the target point.
