Somebody should do a Kickstarter to make and ship copies of this kit for $5 or $10.

You can order one here...

(full disclaimer, this is my company, we make and ship lots of stuff so this will get delivered, unlike some kickstarter projects)

Fisher Price should release a version that takes a smartphone instead of a picture disc.

or maybe one with a USB port or SD slot.

They also get a choice of LG or Samsung Android wear device, as well as everyone will get a Moto360 when they ship.

I don’t really understand why they do that. Isn’t there more than enough demand? They don’t have to create weird incentives to attract the wrong people! They want people to attend who will actually get the most benefit (knowledge about making things on various Google platforms) from it and benefit Google in turn, not anyone else.

There was some HN discussion about this a few weeks ago. It was mentioned that the freebies attract opportunists who just want to acquire gadgets to flip them on ebay. Legitimate developers are crowded out of the conference as a result.

In my opinion, the solution is to put the gadgets in generic packaging and, maybe, if there's enough time, key them to an attendee's badge. Then, the flippers will have to market them as "open box" and "like new".

It'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…

> In fact, many people have reported that spending time in VR, and taking a break whenever motion sickness creeps up, actually reduces motion sickness outside of VR. As in, people are saying "After playing in my Rift for a few weeks, I can suddenly read in the car for the first time!" Is this because the VR experience is causing your brain to recalibrate your vestibular system [1]? [1] http://en.wikipedia.org/wiki/Ve…

Hopefully not recalibrating it to "ignore" your vestibular system..

I did something like this using the open source vnc viewer for android. I had the idea that you could make a 10,000 x 10,000 pixel virtual screen and then use it for programming. You could turn your head and phone would then show a different part of the screen. Also I had it so if you tilted your head left or right it would zoom in or out based on the direction.

It worked well enough, but my phone's resolution was only 1280x800 which is 640x800 per eye. Not enough to really be able to program well.

I just got the quad hd LG G3 though, so I'm going to try it again as soon as I can get a good setup (I'm in hong kong right now so ordering things online is a little tricky). If anyone wants the (hacky) source code, and a brief manual, let me know.

BTW, I just used a hat with cardboard and tape to hold the phone and several pairs of high strength reading glasses worn on top of each other to get the lenses right.

I suspect it's more like "decoupling" vision and vestibular system.

I'm not sure where to buy the lenses in China. Would these work? http://item.taobao.com/item.htm?id=38928988190

I wonder if these would work http://www.aliexpress.com/item/LED-44-5mm-convex-lens-optica... They look close. I need something in Australia. That thing on tabao looks so geeky, I am not sure which is worse the cardboard or the plastic.:)

Yeah, I don't know what the purpose is of the cardboard device on taobao. The logos are for online video services, so maybe it's so you can watch stuff on a small screen but make it feel like you're in a cinema :)

In case it's useful for anyone else:

- Ring magnet 20mm x 4mm: http://item.taobao.com/item.htm?id=23637980267

- Ring magnet 18mm x 4mm: http://item.taobao.com/item.htm?id=17740389918

- Ceramic magnet 20mm x 3mm: http://item.taobao.com/item.htm?id=18786950677

Obviously, I only just ordered these so I have no idea whether these items will turn out to be suitable.

> 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…

John Carmack talked about latency issues in modern graphics pipeline in length: http://www.altdev.co/2013/02/22/latency-mitigation-strategie...

Eh. Only if you want the price of that Fisher-Price VR viewer to jump from $20 (plastic housing and a couple of lenses/magnets) to $500.
