First Claim
Patent Images
1. A cursor for use with a sheet bearing an image, the cursor comprising:
- a body movable by an operator over the sheet;
electronics for generating modifiable information representing any of a plurality of different objects;
a transparent two-dimensional display mounted to the body in a manner such that a portion of the image on the sheet is visible to the operator through the display and coupled to the electronics such that the operator views a selected one of the objects superimposed upon the image portion of the sheet through the display.

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.
