This video, created by SensoMotoric Instruments, demonstrates their latest technology, the External Video Package for the iView-X Red remote eyetracker. It is being used here to track the player's attention within a videogame without the need for special headgear.

I am not affiliated with the product, but I do have written permission to upload this video for use in my blog post. The ownership of the video remains with SensoMotoric Instruments.

In the UK, interested parties should contact Tracksys.
