BullsEye is a software system that makes it possible to track graphical markers and fingers on interactive tables. The position and movements of objects equipped with BullsEye markers are converted into a stream of real-time data, making it possible to use the objects as interaction tools. BullsEye is a system developed by CAVI that is similar to a commonly used system called ReacTIVision. However BullsEye offers more precise tracking. BullsEye can supply output for a common protocol for interactive tables (TUIO), and for WebSocket.

BullsEye tracking tags mounted on several cubes which are used as an interaction device to produce and control music on RadarTable – an application for interactive tables.
