Electromagnetic Tracker

Electromagnetic based tracking devices are used in 'fishtank' VR systems such as CAVEs, CUBEs and Hemispheres to monitor the viewer's head position and update the view they see as the user's head moves.

The tracker reports its position in relation to a fixed transmitter, the tracking range is limited to a half-dozen feet at best. Beyond this range, error percentages spike swiftly. Due to the intense processing required to work out an electromagnetic signal in terms of 6DOF position, they suffer from enough latency to be noticeable by the user, and can lead to simulator sickness over extended periods.

The disadvantage of an electromagnetic tracking system is that only one user at a time may interact directly with the fishtank VR, regardless of how many are immersed within it.

Putting the Chemical in Electrochemical Brain Interfaces
Neuroprosthetics along with less invasive brain machine interfaces have really gone from strength to strength over the past decade. However, all of them are still detecting or modifying signals that are electrical in nature, whilst the brain itself is electrochemical. Now, from a rather unlikely source, comes the first evidence that a chemical detector and tracker is actually possible inside a complex multicellular structure.
