1. A data holding device holding instructions executable by a logic subsystem to: render a three-dimensional virtual gaming world for display on a display device; receive a virtual skeleton, including a plurality of joints, the plurality of joints including a left hand joint and a right hand joint, the virtual skeleton providing a machine readable representation of a human target observed with a three-dimensional depth camera; render a control cursor in the three-dimensional virtual gaming world for display on the display device, a screen space position of the control cursor tracking a position of the left hand joint or the right hand joint of the virtual skeleton as modeled from a world space position of a corresponding hand of the human target; lock the control cursor to an object in the three-dimensional virtual gaming world if a grab threshold of the object is overcome; when the control cursor is locked to the object, move the object with the control cursor such that the world space position, of the corresponding hand of the human target moves the object in the three-dimensional virtual gaming world; and unlock the control cursor from the object at a release position of the object within the three-dimensional virtual gaming world if a release threshold of the object is overcome.
