Question?!?! Peripheral Vision AGHH

Tried oculus rift dev kit for first time yesterday and must say its quite the expereince. I was told it would cover your field of view which it did not. 1 inch black borders on all sides make me feel like i am wearing goggles. wider field of view would make it that much more immersive even without high end resolution.

Will the consumer product cover our peripherals completely? Thats what im most worried about...

In the Rift DK, the main limiting factor to FoV is that the lens borders define the edges of what you can see when you rotate your eyes. In a future Rift model, the FoV could be improved by using larger lenses, with a portion removed to fit closer to the nose and eyebrow ridge, getting the lens center where it belongs. Using the A lenses, with your eyelashes brushing them, maximizes your FoV (so much that looking to the outer edges requires rotating your eyes to the point where they actually hurt a little, at least in my case). In my experience, using the C lenses discards about half the pixels (and significant FoV).

"Completely" is unlikely, considered that each eye can see about 180-degrees (when looking outward to avoid nose occlusion), and combined peripheral vision (including eye rotation) is about 270-degrees. Palmer did play with a 270-degree HMD in his pre-Rift days, but that would be impractical in a stylish consumer Rift device using modern affordable technology.

However, there is still some room for improvement in a consumer Rift model, especially in the inner edges (i.e. more stereoscopic overlap with less occlusion by a center divider, which can be achieved with lens offset and matching tangential lens distortion correction).

Very informitive. Would you think it possible if we "curved" the lenses around our eyes instead of using larger surface area/flat looking eye pieces?

I purchased several pairs of +10 diopter aviator-style (large lenses) reading glasses from an ebay store, for HMD experiments. They wrap around my eyes, and they have huge pincusion distortion making the screen look very dished out (curved around my face). And quite interestingly, they have almost no chromatic aberration.

However, +10 is not enough for a 7-inch display (but perhaps enough for a 10-inch display), at least for my eyeglass prescription (somewhat myopic).

Considering that reading glasses are rated in diopters, while magnifying lenses are rated in 'x' magnification (i.e. 3.5x), here is a conversion chart:

In this case, +10 diopter is about 3.5x magnification (somewhat less than the lenses used in the Rift DK), which is why I mentioned above that they may work well with a larger display (such as an iPad3 display, some of which I also purchased for that project). I would like to find some +20 diopter glasses, if such a thing is available anywhere at an affordable price. +10 is the strongest I could find at the time (before the Rift began shipping).

There are some things you can try like what this guy at Hackaday did to improve the sense of immersion.

In this forum, you only put the video identifier between youtube tags, like this:



Beware that apple recently patented putting ambient lighting in an HMD, along with tons of other obvious ideas (including rectangular shapes with rounded corners, and the color black).
