Choosing state-of-the-art standard components that are commodities like capacitors, resistors, Op Amps or drivers is relatively fast, as there are plenty of compatible options, of similar performance and cost. However, when it comes to DSP (digital signal processors) and microcontrollers, a joint decision is made usu- ally between the hardware engineer and the system architect, taking into consideration software/firmware designers, computing capacity, memory, A/D D/A resolution and the capacity for real-time error compen- sation and correction. 6 VR EM MOTION TRACKING SENSORS & APPLICATIONS Choosing the right digital hardware in virtual reality and augmented reality systems is one of the most im- portant important decisions you will make, and it’s trickier than it seems. Every aspect of the future product, from cost to performance, flexibility and marketing strategies will de- pend on those decisions for the duration of the product lifetime. 7 VR EM MOTION TRACKING SENSORS & APPLICATIONS That being said, the performance of a virtual and augmented reality motion tracking system also lies in the selection of the right tracking technology: > Visual/ Optical > IMU (Inertial Measurement Units) > Electromagnetic, within which we can point out two types: • DC permanent or pulsed magnets • AC Electromagnetic sensing 3DCOILS, THE PRISTINE 3D EM TRACKER FOR VIRTUAL AND AUGMENTED REALITY 8 VR EM MOTION TRACKING SENSORS & APPLICATIONS Introducing 3DCoils, the pristine 3D EM tracker for virtual and augmented reality. Among its many advantages, it boasts: > Lower Latency: real-time data output provide immediate feedback without post-processing of position and orientation data. > No line of sight needed: LF Magnetic Fields can reach antennae through solid objects. > Sensors are never occluded. > No fixed referenced emitter or multiple fixed calibration elements. > Can deliver longer range tracking than competing technologies. > Operates at lower power levels. > Offers the best signal-to-noise ratios. > Multiple tracking systems can be used in the same environment, without any cross-talk interference. > Can be embedded inside any kind of enclosure or housing, except for ferromagnetic materials. > Even completely covered, they still track position and orientation seamlessly, due to the long wavelength and low field attenuation in paramagnetic and diamagnetic environments. > No Drift. > Unmatched precision of 0,01m, with reliable & repeatable tracking results. 3DCoilCubesTM and 3DCoilsTM are extremely flexible 3D EM trackers for VR, entirely customizable and easy to setup. It is possible to fine-tune the settings to meet application needs or environment changes. So, what key parameters should you look at to choose a TX emitter coil or a specific RX receiving sensor coil?
