Small VR 3D motion tracking sensor for immersive experience and tracking in augmented reality environments

PREMO claims to offer the smallest VR electromagnetic motion tracking sensor with a size of just 6mm x 6mm x 2mm. These components are fully magnetically isotropic 3DCoilTM trimmed for VR devices. They have been designed with a fully protected LDS metallized housing that makes the external footprint 7mm x 7mm and includes three identical axis of 1mH at 20kHz. These products target systems that compete with IMU, which have several disadvantages solved by 3D electromagnetic tracking. The 3DV06 Series features a low profile – less than 2.5mm – and is fully isotropic. These parts are delivered in tape and reel for SMT pick and place according to EIA 481 (2,000pcs/reel). It has been engineered to be RoHS and REACH compliant and has been also tested to endurance in conformity with AECQ200 for automotive and wearable applications. Some examples are VR gloves, motion capture clothing, AR/VR pointers for tools/medical devices for training purposes, and more. “IMU systems are complex from a mechanical point of view and are prone to accumulated errors, since they integrate acceleration vs time in order to calculate speed and position,”, states Sergio Cobos, R&D engineer at PREMO. “This accumulates errors along time, and creates a drift that affects position, latency and accuracy. Instead, EM systems do not experience this error, and that enables this technology to reduce latency and increase accuracy.”
