BULLSEYE: A Compact, Camera-Based, Human-Machine Interface

BULLSEYE is a flexible, computer input device that operates by generating and analyzing the image of known “props” at 60 Hz to determine position, orientation, and user-controlled internal state variables. The compact device, containing both the camera and processing engine, has been built and fielded. This paper provides an overview of the concept and hardware, then examines the problems and design strategies associated with the interrelated areas of the environment, prop design, and color detection.
