EMF sensors detect position and orientation using stable electromagnetic fields. Unlike optical systems that rely on cameras, lighting, and line-of-sight, EMF-based tracking works independently of visual conditions. This makes it powerful for tracking hand movements in complex, cluttered, or obstructed environments.
In EMF-based motion tracking, a central transmitter emits an electromagnetic field, while multiple receivers, embedded in a glove on fingertips, measure changes in the field as the hand moves. These changes are then converted into precise 3D position and orientation data, which MANUS Core further processes into skeletal and ergonomic information.
MANUS Metagloves integrate EMF technology into professional-grade hand-tracking hardware. Each glove houses EMF receivers embedded in the fingertips, which continuously read the electromagnetic field generated by a central transmitter located in the top casing on the back of the hand. As the fingers move through space, the receivers detect the strength and direction of the electromagnetic field, and advanced algorithms convert these signals into accurate, real-time 3D position and rotation data.
The sensor data will be further processed into skeletal and ergonomic information in MANUS Core, our real-time software platform. The result is drift-free, occlusion-free hand and finger tracking that remains accurate and stable across sessions, even in challenging lighting or crowded workspaces.
EMF sensors offer several key benefits over traditional optical or inertial tracking systems:
MANUS Metagloves combine EMF tracking with inertial measurement units (IMUs) and flex sensors to deliver professional-grade, 3D hand and finger tracking. This hybrid system overcomes the limitations of other technologies by providing drift-free, occlusion-resistant, real-time tracking with consistent accuracy across sessions.
