I wonder if setups like Gear and Daydream will be able employ eye tracking and/or FovR in the near future. They already have front facing cameras that might work for it.

The front facing cameras aren't for tracking the eyes.  They are for getting a 3D image of the room.

But there are various projects to try adding on a camera for other headsets, I don't see why Gear can't have one.

 The psvr needs tangible upgrades not token gestures. 

I think people are going to be very impressed with the jump.

Higher resolution, larger field of view are definitely going to happen.

Foveated rendering, wireless would be awesome, but I'd expect only the former.

I wonder at this point if VR wouldn't work better in a helmet. You'd have more space to put components and you could space them out more. It would probably be more comfortable due to better weight distribution as well.

I don't really think it'd be worth it.  The headsets aren't terribly heavy.  

The halo design on the PSVR is actually very comfortable.  

Impressed because the PSVR is very basic and the tech has come on a lot since? So a PSVR2 in 2021 should be a lot better then the first? I hope they release a $299 VR beast and bring it's price down over the course of the gen.

I was referring to the front facing cameras on the smartphones these headsets use.

Eyetracking cams usually work with an array of infra-red lights around the eyes and infra-red cams tracking the pupil movements (~250Hz seems to be the magic number to enable FovR). Smartphone (visible light) cams probably won't get enough light to reliably track the pupil, especially at 240+ images per sec. Btw I've yet to see a phone with cams at both ends of the display.

Is that not bad for your eyes having infra-red lights shining into them?

Sun light contains infra-red....
Point a remote at your eyes, it doesn't hurt :)

Haha when I wrote the comment I was thinking back to physics class. I'd a feeling I'd be pulled up on it!

Do you really need both ends, though? One could be enough to reasonably predict the focus of the other as well - at least enough for the general area for foveation, even if it may not be precise enough for something like aiming. Obviously bespoke hardware would be better, but it could be enough for the entry level.

You need a front facing one for head tracking, one facing your eyes to track your pupils. You can turn your head to the right and your pupils to the left independently!

Blinking to select, how does it filter out natural blinks, and won't that get tiring. Just imagine playing those click thousand times a minute games :)
