Abstract
A cursor is provided which has a cursor body and a lens holding portion. The lens holding portion has a liquid crystal display screen therein, adapted for use as a lens. Multiple cross-hairs can be displayed on the lens using the liquid crystal display screen, and can also be modified to display supplemental information on the liquid crystal display. At least two sensors can also be coupled with the cursor for re-orienting the cursor, and adjusting the displayed cross-hairs on the liquid crystal display relative to the orientation.
