ABSTRACT:
A method for generating positional information of an object is carried out by providing a reflector in the object and by providing a personal device containing a light generator and an imager. The personal device is mounted on a person holding the object at a mounting location that is identified to provide a first unobstructed line-of-sight between the light generator and the object and a second unobstructed line-of-sight between the imager and the object.
