![]() ![]() ![]() There is more chromatic abberation near the edges (mostly blue), but that could be adjusted in software. Due to my stacking arrangement it does not stretch vertically near the edges as much as horizontally, but still it looks amazing, and the correction you used in your "rift-adjusted" video actually shows doorways as rectangular in these lens stacks. By stacking them, I am taking advantage of the extreme off-center distortion from the edges of these 6-inch diamemeter lenses. I always thought that fresnels would work well.I am surprised at how well it worked with these newer cheap fine-pitched fresnel lenses. I may mount my cut-down fresnel lenses very close to my eyes in modified swim goggles (also available from my local dollar store):Īnd I may try attaching my Nexus 7 to dollar store saftey goggles like these (but they may need a better strap):Ĭybereality wrote:Sounds good, geekmaster. This is a popular lens available from many stores, but most places sell it in multiples of 24: ![]() These cheap dollar store lenses are much higher quality (finer pitch) than used in that device.īy overlapping the fresnel outer edges, their extreme offset simulate looking through the edges of the 5x lenses causing more geometric distortion (desirable in this case, pushing the image beyond the nose boundary).Īny perceived distortion is quickly lost in the game environment in my experience, but it could be compensated in software (including shifting blue for chromatic aberration adjustments).Īnd these lenses are cheap too (only one dollar per eye from my local dollar store). I got the idea from an old "Virtual Reality Construction" book that came with fresnel lenses and a cardboard fold-up frame, which had a string to tape to a CRT monitor so it could hang down against the screen and to use like binoculars on a displayed stereo image. MUCH better than I had expected, and extremely lightweight lenses. In fact, after having such a super-normal FoV, it makes me much more aware of my eyeglass frames (and my nose) which are obstructing FoV that I saw inside the game environment. If you normally wear glasses, but blurriness at the corners is less than from real glasses (even large aviator-style lenses). I played one of cybereality's Rift-adjusted videos from the Vireo Perception thread at fullscreen on my Nexus 7 (7-inch LCD), and it was great. Although it causes chromatic aberation on text (mostly blue), that is rarely noticeable in a game environment. When in focus on my Nexius 7 screen, it completely fills my horizontal FoV, including where my nose should be and as far as I can stretch my gaze away from my nose. Then I cut out the corners to fit my nose and inner eye brow. I cut it into 3 pieces each two inches wide and overlapped them (all with ridges toward the eye, no rotation). It is about 2 inches tall and 6 inches wide.
