Eye tracking capability within virtual reality headsets allows for a similar technique that follows the same principles as your eyes.
While the product itself isn't available just yet, it won't arrive until the second quarter of 2019, HTC showed off the HMD with built-in eye tracking at this year's CES.
Interestingly, HTC says the headset can be powered via a PC or "other methods", hinting that customers can will be able to tap into the power of the smartphones for using the Cosmos on the go. And it is so confident in its VR ecosystem that it's opening up an unlimited subscription tier for all the VR experiences you can get.
Besides just enabling new controller-less experiences, the company also notes the new headset could have a significant impact on accessibility since it could open up VR experiences to people who aren't able to use traditional hand controllers.
This is the issue with launches like the HTC Vive Cosmos, that we're told is "coming soon".
HTC's Viveport Infinity subscription offers unlimited access to VR
Although an exact release date has not yet been given, the Cosmos developers kit is expected to be available in the next few months.
The VR market is different than it was in 2016 when HTC first released the Vive.
While Facebook and Oculus are out there going after regular folk with the Oculus Go and the upcoming Oculus Quest, HTC Vive seems to be headed the opposite direction by attempting to push VR experiences even further with new Vive Pro Eye. I haven't been impressed by any dual-camera setups yet, be it the Vive Focus or the bevy of Windows MR headsets, but I'll reserve judgment for now.
Viveport Inifity launches April 5.
On the consumer front, HTC outlined enhancements to its subscription service as well as a headset for the masses called Cosmos.
"This year, Vive has set out to bring everyday computing tasks into VR for the first time", said HTC Vive vice president Michael Almeraris in a statement. It doesn't look like the Cosmos has wires though, which makes me wonder whether the recent HTC Vive wireless adapter - the one using Intel's WiGig tech - is built straight into the headset this time. The Vive Cosmos can be paired with a PC, and will get smartphone connectivity in the future.
