Wireless 6DOF Electromagnetic Tracker

Freedom of movement without compromise: precise 6DOF tracking, wireless and without visual connection

The G4 system is a compact, wireless tracker that allows unrestricted movement. It uses the powerful electromagnetic AC technology to deliver high-quality 6DOF real-time data without the complications of hybrid technologies or the need for visual connection. The data from the sensors are transmitted directly to the PC via high-frequency connections (RF), which enables a seamless data stream without drift. G4 is ideal for innovative solutions in the areas of training and simulation, rehabilitation, physiotherapy, biomechanics, sports analysis, and virtual or augmented reality.
