Abstract

This invention comprises a method and apparatus for displaying full color, high resolution dynamically generated real images and allowing the user to have direct interaction with the image. This input/output device provides an intuitive computer/video interface that permits the operator to grab, translate and manipulate a real image. The apparatus comprises a pair of coaxially positioned parabolic mirrors and a video imaging device allowing for 360 degree viewing. The real image, that appears floating within the opening of a viewport, is completely interactive by means of a detection system that tracks the operator, allowing the user to place his/her hand or finger through the image and engage it. Applications for this device are wide ranging, and include, for example, computer-aided design (CAD) and the entertainment/gaming industry by abandoning the conventional keyboard and mouse and allowing the user to have direct contact with the image.

Claims
