Sensomotoric Instruments (SMI) is a German-based eye tracking company who has released an eye tracking kit for the Oculus DK2 & Gear VR, and most recently for the HTC Vive. At SIGGRAPH this year, Nvidia was showing a foveated rendering demo where it only renders high resolution to the sections of the scene that you are actually looking at. It’s really an imperceptible difference that would allow mobile technologies to render higher resolution scenes, or potentially help make it more feasible to wirelessly transfer data to a desktop VR HMD.
At SIGGRAPH, I had a chance to talk with Walter Nistico, Head of R&D and Lead Architect Computer Vision, as well as Tom Sengelaub, Manager Solution Delivery, about SMI tracking, and some of the applications in foveated rendering, medical applications for autism research and concussion detection, marketing and analytics, and even deception detection with Converus’ EyeDetect.

Researcher Hao Li told me that eye tracking is pretty essential in order to take VR social presence to the next level, and so I expect that the second generation of the Oculus Rift and HTC Vive would both include eye tracking technologies. In talking to Walter and Tom at SIGGRAPH, they’re also very confident that we’ll start to see eye tracking technologies in the next generation of VR headsets.
From SMI’s perspective, they’re hoping to be able to license their eye tracking algorithms to the big headset manufacturers. In my interview with Tobii eye tracking, they also told me that they’ve also been in discussions with some of the major VR HMD manufacturers. SMI says that the hardware required for eye tracking is not a huge barrier, and so it will likely be a matter of whether the eye tracking algorithms are going to be developed in-house or licensed from one of the big eye tracking players.
