Contracting work for mtronix, a Berlin company that specializes in precision measurement instruments. ETD is short for Eye Tracking Device, although, to be more precise, it’s actually the pupil that’s being tracked. The technology is being used for LASIK as well as for medical research on the vestibulear system and how our eyes can contribute to our sense of balance. In fact, the system has made it up to the International Space Station (ISS) where these effects are researched in zero-gravity. ETD is built around the same processor as the gluiph, the TriMedia.
