1. A method, comprising:
- receiving, by a computer executing a non-tactile three dimensional (3D) user interface, a set of multiple 3D coordinates representing a gesture by a hand positioned within a field of view of a sensing device coupled to the computer, the gesture comprising a rising motion along a vertical axis in space wherein the hand performs the rising motion for at least an unlock gesture distance at a minimum unlock gesture speed; and
transitioning the non-tactile 3D user interface from a locked state to an unlocked state upon detecting completion of the gesture.

Abstract
A method, including receiving, by a computer executing a non-tactile three dimensional (3D) user interface, a set of multiple 3D coordinates representing a gesture by a hand positioned within a field of view of a sensing device coupled to the computer, the gesture including a first motion in a first direction along a selected axis in space, followed by a second motion in a second direction, opposite to the first direction, along the selected axis. Upon detecting completion of the gesture, the non-tactile 3D user interface is transitioned from a first state to a second state.

6. An apparatus, comprising:
-
a sensing device; and a computer executing a non-tactile three dimensional (3D) user interface and configured to receive, from the sensing device, a set of multiple 3D coordinates representing a gesture by a hand positioned within a field of view of the sensing device, the gesture comprising a rising motion along a vertical axis in space wherein the hand performs the rising motion for at least an unlock gesture distance at a minimum unlock gesture speed, and to transition the non-tactile 3D user interface from a locked state to an unlocked state upon detecting completion of the gesture. - View Dependent Claims (7, 8, 9, 10)

11. 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 non-tactile user interface, cause the computer to receive, from a sensing device, a set of multiple 3D coordinates representing a gesture by a hand positioned within a field of view of the sensing device, the gesture comprising a rising motion along a vertical axis in space wherein the hand performs the rising motion for at least an unlock gesture distance at a minimum unlock gesture speed, and to transition the non-tactile 3D user interface from a locked state to an unlocked state upon detecting completion of the gesture.

12. A method, comprising:
-
receiving, by a computer executing a non-tactile three dimensional (3D) user interface, a set of multiple 3D coordinates representing a gesture by a hand positioned within a field of view of a sensing device coupled to the computer, the gesture comprising a rising motion along a vertical axis in space; determining whether the gesture of the hand included a rising of the hand by at least 20 centimeters; and transitioning the non-tactile 3D user interface from a locked state to an unlocked state upon detecting completion of the gesture, wherein the transitioning of the user interface from a locked state to an unlocked state is performed only if the upward gesture included a rise of the hand by at least 20 centimeters.
