BullsEye is a computer vision software application developed by CAVI for optical tracking of graphical markers, ‘fiducials’, on tangible tabletops. BullsEye is comparable in functionality to the open source fiducial tracking system, reacTIVision, but offers significantly faster and more accurate tracking of fiducials and, additionally, features finger tracking. Accurate tracking is crucial when tracking objects for the purpose of 3D projection mapping, and BullsEye is developed to provide tracking with sub-pixel accuracy to accommodate advanced 3D projection on tracked objects on an interactive tabletop. BullsEye can serve events to an interactive table application both through the TUIO protocol and through a Websocket connection.
BullsEye features are detailed in the paper “BullsEye: High-Precision Fiducial Tracking for Table-based Tangible Interaction”.
BullsEye tracking tags mounted on several cubes used as interaction devices, tangibles, to produce and control music on RadarTable – an application for interactive tables.
