VR/AR EM Motion Tracking Sensors


Electromagnetic motion tracking systems work by using a low frequency isotropic magnetic field generator (3D emitter) and one or several isotropic 3D magnetic sensors. Emitter and receiver sides need special 3D magnetic coils to generate and receive the magnetic field signals.This wide offering is led by two brands that became the leading providers of virtual visualization technology: Samsung and HTC Corporation. There are very big differences between them when searching for an HMD, so a comparison is helpful, so let’s consider their specifications and applications.


This HMD is based on the use of a mobile phone as hardware platform to run the applications, games or 360-degree videos. The Gear VR has evolved to this latest version, with less weight, a most convenient design and remote control for an easy-to-use navigation and interaction. In our review we will consider the latest version of Gear VR with an Oculus-powered controller.

Premo’s 3DCoils and 3DCoilCube motion tracking magnetic sensors use a 3D emitter antenna that generates an electromagnetic field. The use of low frequency/long wavelength signals allow tracking sensors to be embedded or out of sightline, ideal for any virtual reality controller.


Due to Premo’s wide experience in these products, we offer a large portfolio of Tx/Rx electromagnetic tracking sensors, covering all kinds of range, dimensions or performance constraints. From cube to low-profile configurations, and from lower to higher sensitivities, the range of possibilities is very wide.
They are entirely customizable and deliverable within 4 weeks. We are equipped to produce over 50 million 3DCoils and 3DCoilCubes per year.
