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.
These sensors offered to the AR/VR market include more than six degrees of freedom (6DOF): 3 positions and 3 orientations generated by 3 transmitter coils and 3 receiver coils.Typical operating frequencies range are from a few kHz (even Hz) to several kHz (20-50-60kHz).
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.
Choosing the right digital hardware in virtual reality and augmented reality systems is one of the most important decisions you will make. Cubic design is the most effective approach to an isotropic magnetic coil emitter or receiver.
Already used in some of the world's most advanced VR/AR devices, the 3DCoilCube has an unmatched precision of 0.001m and can track the smallest, slowest movements for optimum 3D motion tracking.
There are four different cubic formats available, depending on core size: 3DCC08 (3DCoilCube VR Rx antenna 8x8mm), 3DCC10 (3DCoilCube VR Rx antenna 10x10mm), 3DCC20 (3DCoilCube VR Tx antenna 20x20mm), 3DCC28 (3DCoilCube VR Tx antenna 28x28mm)
The low profile 3DCoil design achieves electromagnetic sensitivity isotropy by clever design techniques and fine-tuned windings calculations. By using these, the sensor volume required shrinks to SMT PCB mounted components standards (<3.5mm height).
We offer 4 EM Motion Tracking Sensors as standard solutions: 3DV06 (3D VR Rx sensor 7x7x2.3 mm), 3DV09 (3D VR Rx sensor 9.5×9.5×3.1 mm), 3DV11AOI (3D VR Rx sensor 13×11.6×3.45 mm), 3DV15 (3D VR Rx sensor 17×15.3×3.8 mm).
PREMO biggest competitive advantage is the short time-to-market performance when developing a custom-made solution according to customer specifics.
A wide variety of EM sensors can be designed to meet AR/VR systems requirements. From cube configurations to low-profile configurations, and from lower to higher sensitivities, the range of possibilities is very wide:
• Shapes (i.e. rectangular, quasi-cub, ultralow-profile)
• Inductance: Tx (20μH – 2mH), Rx(300μH – 7mH)
• Operation frequency (3 – 300kHz)
• Standard cables to male/female connector
• FPC connection
• Over-Molded (low pressure molding)
PREMO has entered a strategic partnership with Amfitech, highly specialized in electromagnetic tracking systems development and customization.
AmfiTrack is an embedded stand-alone, high precision and low cost electromagnetic tracking system based on electromagnetic field (EMF) tracking, using an EMF transmitter and one or more EMF receivers
Our VR/AR EM Trackers are included in AmfiTrack six degrees of freedom (6DOF) 3D tracking system.
