CastAR Hands-On and Off-Record Look at Next Version

At long last I had the opportunity to try out the CastAR, a glasses-based Augmented Reality system developed by Technical Illusions. The hardware has been in the works now for a couple of years, but every time we have come across a demo we were thwarted by the long lines that accompany them. This time I was really lucky. [Jeri] gave us a private demo in a suite at the Palazzo during CES 2015. Reflecting on the experience, CastAR is exactly the type of Virtual Reality hardware I’ve been longing for.

“Superfan” Gaming Peripheral Lets You Feel Your Speed

Virtual reality has come a long way but some senses are still neglected. Until Smell-O-Vision happens, the next step might be feeling the wind in your hair. Perhaps dad racing a sportbike or kids giggling on a rollercoaster. Not as hard to build as you might think, you probably have the parts already.

HAD - Superfan4Off-the-shelf devices serve up the seeing and hearing part of your imaginary environment, but they stop there. [Jared] wanted to take the immersion farther by being able to feel the speed, which meant building his own high power wind generator and tying it into the VR system. The failed crowdfunding effort of the “Petal” meant that something new would have to be constructed. Obviously, to move air without actually going on a rollercoaster requires a motor controller and some fans. Powerful fans.

A proponent of going big or going home, [Jared] picked up a pair of fans and modified them so heavily that they will launch themselves off of the table if not anchored down. Who overdrives fans so hard they need custom heatsinks for the motors? He does. He admits he went overboard and sensibly way overbudget for most people but he built it for himself and does not care.

Touching Light with Haptic Feedback

Many of us have gone on a stationary romp through some virtual or augmented scape with one of the few headsets out in the wild today. While the experience of viewing a convincing figment of reality is an exciting sensation in itself, [Mark Lee] and [Kevin Wang] are figuring out how to tie other senses into the mix.

The duo from Cornell University have built a mechanical exoskeleton that responds to light with haptic feedback. This means the wearer can touch the sphere of light around a source as if it were a solid object. Photo resistors are mounted like antenna to the tip of each finger, which they filed down around the edges to receive a more  diffused amount of light. When the wearer of the apparatus moves their hand towards a light source, the sensors trigger servo motors mounted on the back of the hand to actuate and retract a series of 3D printed tendons which arch upward and connect to the individual fingers of the wearer. This way as the resistors receive varying amounts of light, they can react independently to simulate physical contours.

One of the goals of the project was to produce a working proof of concept with no more than 100 dollars worth of materials, which [Mark] and [Kevin] achieve with some cash to spare. Their list of parts can be found on their blog along with some more details on the project.

Using the Oculus Rift as a Multi-Monitor Replacement

[Jason] has been playing around with the Oculus Rift lately and came up with a pretty cool software demonstration. It’s probably been done before in some way shape or form, but we love the idea anyway and he’s actually released the program so you can play with it too!

It’s basically a 3D Windows Manager, aptly called 3DWM — though he’s thinking of changing the name to something a bit cooler, maybe the WorkSphere or something.

As he shows in the following video demonstration, the software allows you to set up multiple desktops and windows on your virtual sphere created by the Oculus — essentially creating a virtual multi-monitor setup. There’s a few obvious cons to this setup which makes it a bit unpractical at the moment. Like the inability to see your keyboard (though this shouldn’t really be a problem), the inability to see people around you… and of course the hardware and it’s lack of proper resolution. But besides that, it’s still pretty awesome!

In the future development he hopes to add Kinect 2 and Leap Motion controller integration to help make it even more user intuitive — maybe more Minority Report style.

Happy Meal Hack Produces a Google Cardboard Test

Ever since Google Cardboard came out, [Julian Jackson] had been meaning to give it a shot. Affordable virtual reality? Who wouldn’t! But, he never got around to it — until one day he was sitting in McDonald’s with his son, explaining to him how the latest Happy Meal toy worked — it was a pair of penguin binoculars.

Fast forward past Thanksgiving and Black Friday and [Julian’s] son had completely forgotten about the McDonald’s toy in all the excitement, so [Julian] asked if he could have it. His son was mildly confused, but curious also, so he let his dad take his toy.

After attempting to dismantle it with a screw driver to get at the lenses, [Julian] carefully calculated the best place to simply break it without damaging them. With the precision of a heart surgeon he swung back his trusty hammer…  Continue reading “Happy Meal Hack Produces a Google Cardboard Test”

Ask Hackaday: What is The Future of Virtual Reality?

Most of us have heard of Second Life – that antiquated online virtual reality platform of yesteryear where users could explore, create, and even sell content.  You might be surprised to learn that not only are they still around, but they’re also employing the Oculus Rift and completely redesigning their virtual world. With support of the DK2 Rift, the possibilities for a Second Life platform where users can share and explore each other’s creations opens up some interesting doors.

Envision a world where you could log on to a “virtual net”, put on your favorite VR headset and let your imagination run wild. You and some friends could make a city, a planet…and entire universe that you and thousands of others could explore. With a little bit of dreaming and an arduino, VR can bring dreams to life.
