I like to imagine that Google Cardboard is an internal company joke at the expense of Google Glass.
How can this not be some kind of internal sniping?

#132Ha, I made a thing like this back in 1994 or so out of an old monochrome 640x480 laptop screen, a couple of those plastic fresnel lenses and a whole bunch of glue and cardboard. It worked about as well as you'd expect.
I was totally into the Virtual Reality hype of the day. It's funny to think that 20 years later it might almost be useful. Maybe I'll buy an Oculus Rift to celebrate :-)

#133It's very cool that they are doing this. But, for anyone who tries it, there's something very important to keep in mind: Low latency is critical to VR! Unfortunately, Android sensors and graphics pipelines have very poor latency. If you try this and get terrible motion sickness, don't dismiss VR as a vomit inducer. In fact, many people have reported that spending time in VR, and taking a break whenever motion sicknes…
VR will finally become mainstream when someone fully leverages its motion sickness inducing potential, and develops an effective weight loss system.

#134Earlier quoted context omitted.
> Android sensors and graphics pipelines have very poor latency. I'm not familiar with the sensors latency but the graphics pipeline certainly doesn't have "very poor latency". If you aren't dropping frames the app is just running in double buffering. Android then adds a single extra frame of latency as it doesn't "race the beam" so to speak, so the grand total latency added by the system in the graphics pipeline is…
16ms is way too long for VR.
Game developer here: 16ms is the magic number in frame rates as it means you're hitting 60fps, which is about the same as the human brain's visual refresh rate.

#136has anyone ordered from knoxlabs.com? they seem to be selling it as well.

#137Guys has anyone tried using lenses with 50 mm focal length? Does it have to be exactly 45 mm? I measured the distance from the lens area to the screen of the phone and it is 46mm. I was thinking of using 50 mm lenses. Any ideas? Thanks

I'm not thrilled about this company or my order - fair warning below for others who ordered a lens from them.
tl;dr - the site may have autogenerated an account for you with a weak password if you told it to check out as guest.
First - they didn't have an exact lens match, so I tried ordering two sets of close-to-recommended lenses. My lenses arrived today (10 days after my order, which is probably pretty decent) but I only got one of each, not two sets. OK, this was probably my screw-up, but I definitely knew what I needed and remember trying to tweak quantities on my order to get this right. This is probably my screwup but part of me wishes that it wasn't so easy to screwup online retail (yes, by the customer) like this.
But my bigger worry is this! Now that I've got two individual, unpaired lenses, tonight I'm going back to place a new order. I didn't create an account with my original order so I'm checking out again and choosing the "don't create an account" option again when the site tells me I have an account. That's weird because I definitely know I didn't choose to create an account. But I can't check out in without signing in, so I try using the password generation routine I've been using for years. That doesn't work, so I ask it to email me my password and the email I receive tells me my password is "optics".
1) For obvious reasons, it's really, really, really bad to send a username and password together in an email (my username happened to be my email, but the body of the message makes this explicit, too) 2) I definitely did not create that account or with that password - this seems to have generated one "for" me 3) In doing so, it used a really insecure password and I suspect that same default password is in place for other accounts that have been generated automatically and without consent on the site.
I don't really mean to come slam these guys and their site - it seems like a bit of a mom & pop shop for some specialized equipment - but others who've placed an order here should beware.
