High-performance AR and VR systems work with extremely sensitive, precise, robust, and responsive motion sensors. A VR/AR system developer must consider the use of sensors that provide a truly immersive experience, which relies in the use of highly accurate and sensitive sensors. The use of the right VR sensors can also avoid motion sickness in the device user as a result of incorrect heading information derived from imprecise inertial sensor data.
What sensors are needed for VR and how do they work? VR Sensor coils in EM motion tracking are wound around a ferromagnetic core and placed in the transmit (Tx) and receive (Rx) ends of the Electromagnetic Motion System to generate and receive the magnetic field signals. Premo’s 3D coil technology is composed of 3 orthogonal coils wound on a single cube shaped core or a “low profile” core that receives voltages that represent vectors of the 3 orthogonal components. We review here the different options.
In PREMO we offer a wide range of VR magnetic sensors (both on a cube or a “low profile” core) that covers a wide range of size and sensitivity requirements.
The current VR sensors developed by PREMO with cube cores provide many advantages compared to other standard products found in the market today.
Unmatched sensing precision of 0.001m to, track the smallest
, and slowest movements for optimum 3D motion tracking.
Premo Group uses high permeability NiZn material in all 3DC Low Profile coils (coils are wound directly over ferrite core with high surface resistivity). This material sldo has high thermal stability across the operating temperature range.
Other advantages of these VR low profile sensors are:
