Behold: Valve’s VR And AR Prototypes

Just in case anyone secretly had the idea that Valve Software’s VR and other hardware somehow sprang fully-formed from a lab, here are some great photos and video of early prototypes, and interviews with the people who made them. Some of the hardware is quite raw-looking, some of it is recognizable, and some are from directions that were explored but went nowhere, but it’s all fascinating.

An early AR prototype that worked like looking through a tube into another world.

The accompanying video (embedded below) has some great background and stories about the research process, which began with a mandate to explore the concepts of AR and VR and determine what could be done and what was holding things back.

One good peek into this process is the piece of hardware shown to the left. You look into the lens end like a little telescope. It has a projector that beams an image directly into your eye, and it has camera-based tracking that updates that image extremely quickly.

The result is a device that lets you look through a little window into a completely different world. In the video (2:16) one of the developers says “It really taught us just how important tracking was. No matter [how you moved] it was essentially perfect. It was really the first glimpse we had into what could be achieved if you had very low persistence displays, and very good tracking.” That set the direction for the research that followed.

Learn 40 Years Of Mech Prototyping At Lightspeed

So, what are you doing for the next five and a half hours?  If you’re as busy as we are, you might have to digest this amazing 18 part series of videos over the course of a week or so, but we can almost guarantee you’ll learn a lot. It’s a speedrun through the best collection of Mechanical Engineering knowledge we’ve every come across.

In this epic Youtube video series [Dan Gelbart] shares his knowledge of 40 years of prototyping mechanical designs in a way we’ve never seen before. Not only does he show you how to build things, but he gives away a life time of “tips and tricks” that only a veteran builder would know. There are so many little gems of wisdom in this video series, it’s hard to know where to start with our description. He covers all the usual topics: everything from materials, adhesives, coatings, and such. But the real value of this series is all the little trinkets of information he shares along the way.

Don’t be intimated by some of the tools he’s using – chances are there is a DIY version of the piece of equipment out there, and often you can find a hackerspace or enthusiast in the area who will help you out with their gear. We think this video series should be a must watch for any engineering student or hacker. We made a video playlist for you so you can start watching the videos after the break.
