3D POINTING SYSTEM

摘要

A method of determining a direction in which a person is pointing comprising: acquiring a 3D image of the person; determining a first set of spatial coordinates for a location of an eye of the person responsive to the 3D image; determining a second set of spatial coordinates for a location of a pointing region of a body part or an instrument that the person orients to indicate a pointing direction; determining a line responsive to the spatial coordinates; and determining a pointing direction for the person responsive to the line.
