1. A three-dimensional imaging and display apparatus, comprising:
- a processor;
a first circuit coupled to the processor for optically detecting user input in an imaging volume;
a second circuit coupled to the processor for compensating for parallax in the optically detected user input, wherein the second circuit compensates for parallax as a function of a scan coordinate defined by a mirror system position and at least the measured distance from the minor system to a target object; and
a third circuit coupled to the processor for presenting visual image user feedback concerning the optically detected user input.
