Abstract
The technology disclosed relates to automatically interpreting a gesture of a control object in a three dimensional sensor space by sensing a movement of the control object in the three dimensional sensor space, sensing orientation of the control object, defining a control plane tangential to a surface of the control object and interpreting the gesture based on whether the movement of the control object is more normal to the control plane or more parallel to the control plane.
Claims16
A method of navigating a multi-layer presentation tree using gestures of a control object in a three-dimensional (3D) sensor space, using a 3D sensor, the method including:
- processing an output of a camera of the 3D sensor thereby sensing a movement of the control object in any direction in the 3D sensor space using a control plane that remains tangent to a surface of the control object throughout the movement of the control object, the control plane being defined by a sensed orientation of the control object;
- and
- interpreting by a computing device a direction of the movement of the control object as scrolling through a particular level of the multi-layer presentation tree when a direction of the movement of the control object is more normal with respect to the surface of the tangent control plane than parallel with respect to the surface of the control plane.
A method of interpreting a gesture of a control object in a three-dimensional (3D) sensor space relative to one or more objects depicted in a display, the method including:
- interpreting, by a computing device, a sensed movement of the control object moving in any direction through the 3D sensor space using a 3D sensor as a path on the display;
- and
- duplicating an object, of the one or more of the objects depicted in the display, that intersect the path as interpreted.
