Patent ID: 6898307

Claim:
A method of verifying a projected image within a three-dimensional view plane of an augmented-reality display system as a preselected movable real object disposed in three-dimensional free space, whereby the preselected movable real object may be employed as an interface tool for the system, comprising steps of: identifying a representative characteristic of the preselected movable real object within the three-dimensional view plane, the preselected movable real object is comprised of three equidistant line points disposed in free space, and wherein the representative characteristic comprises shape and location of the preselected movable real object and is exclusive of preselected marked standards and printed identifiers; determining dimensional aspects of the preselected movable real object from the projected image including the detection of projected dimensions of the three equidistant line points; computing a corresponding dimensional identity and location of the preselected movable real object at an object point relative to the view plane including calculating X, Y and Z coordinates in real space of the preselected movable real object at the object point based on the projected dimensions of the three equidistant line points in the view plane and known augmented-reality display system geometric dimensions; and verifying whether the dimensional identity and location are reasonably consistent with predetermined standards for the preselected movable real object.
