A lot has been said about whether foveated rendering (in short, rendering the area we are looking at with more quality than the rest) is the best solution to create HMDs with a high resolution with contained graphics power requirements. For this, a system is necessary that allows us to follow our gaze quickly enough so that we do not notice it.
FOVE has been featured at the TechCrunch Disrupt. This Tokyo-based startup claims to have achieved a system capable of following our gaze and adjusting the level of detail of the area to be rendered with the necessary speed, and has shown a prototype of it. They have not revealed the details of their technology, as they are still pending patent registration, but they have claimed that they use infrared technology capable of following the movements of our eyes with minimal latency and enormous accuracy.
In addition, FOVE participates in the Microsoft Ventures Accelerator program in London, and its creators have stated that they intend to talk to Microsoft to offer them the possibility of integrating it into the Xbox platform, although at the moment they have not finalized anything. They are of the opinion that console gamers are usually reluctant to pay for a device that costs more than the console itself, and apparently FOVE would be more expensive than Oculus Rift, which is logical if it integrates eye tracking technology.
At the moment there are several functional prototypes like the one you see in the image, and they plan to launch a Kickstarter campaign along with the SDK next year, with the aim of having a commercial version in 2016.
