There is now another omni-directional treadmill project on Kickstarter, this one called the Wizdish. It’s a passive design, similar to the Omni, however it does not allow the user to lift their feet. It works by wearing special shoes with low-friction tiles on the bottom. This allows you to slide your feet back-and-forth easily without the need to pick up your feet. I actually got to try a prototype of this device, and it was certainly interesting. It did not blow me away, but seemed intriguing enough for me to want to get in on the Kickstarter. And this isn’t even that only other ODTRead More →

In preparation for my 3D game engine, I have been trying to read all I can on 3D engine design and architecture. Although there are some good books out there, it’s very difficult to find a text that will walk you through everything you need to know. That said, 3D Game Engine Architecture: Engineering Real-Time Applications with Wild Magic by David H. Eberly gives it a good attempt. The book covers the author’s Wild Magic engine, and discusses certain choices he made when developing the engine. It briefly touches on OpenGL, discusses abstracting away platform-specific details, 3D mathematics (and there is a lot of math in thisRead More →

Looks like there’s yet another virtual reality project on Kickstarter. Well, I guess this is not strictly a VR thing, but it certainly could be used as such. Basically the ARAIG is a vest that you wear while gaming, and it provides force-feedback when you are getting hit in the game. While it does include vibration (like current controllers), it also has direct stimulation with TENS, which could get pretty intense depending on how much power they are pumping through. I really think a vest like this can add a lot of immersion, specifically in first-person shooters. I backed the project at the $299 level,Read More →

  The above video is demonstrating a 4.5″ flex sensor made by Spectra Symbol that I got from Sparkfun. Hooked it up to an Arduino and had it print the values to the serial monitor. Since I don’t have a tripod, it was going to be difficult to demo with only one hand, so I ended up taping the sensor to my finger. Ghetto? Yes. But it actually was pretty fun, and gets me psyched up to buy a glove to mount this on. So far it seems to work good enough for my needs.Read More →

The Virtuix Omni Kickstarter campaign was fully funded within hours of the doors opening this morning. If you haven’t heard of this device before, it’s basically a passive treadmill. It allows you to walk in any direction inside a virtual world, without actually moving in the real world. At the time of writing, they are sitting on over $454,000 with 47 days left to go. An amazing achievement and testament to how popular virtual reality has become recently. I backed them for $399. Let’s hope they actually ship next January.Read More →
