Abstract
A three-dimensional imaging and display system is provided in which user input is optically detected in an imaging volume by measuring the path length of an amplitude modulated scanning beam as a function of the phase shift thereof. Visual image user feedback concerning the detected user input is presented.
Claims20
A method for detecting a user input in a three-dimensional volume, the method comprising:
- optically detecting a user input in an imaging volume;
- compensating for parallax in the optically detected user input as a function of a scan coordinate defined by a minor system position and the measured distance from the minor system to a target object;
- and
- presenting visual image user feedback concerning the optically detected user input.
