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.
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.
Off-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.
My first day on the ground at CES started with a somewhat amusing wait at the Taxi Stand of the McCarran International Airport. Actually I’m getting ahead of myself… it started with a surprisingly efficient badge-pickup booth in the baggage claim of the airport. Wait in line for about three minutes, and show them the QR code emailed to you from online registration and you’re ready to move to the 1/4 mile-long, six-switchback deep line for cabs. Yeah, there’s a lot of people here for this conference.
It’s striking just how huge this thing is. Every hotel on the strip is crawling with badge-wearing CES attendees. Many of the conference halls in the hotels are filled with booths, meaning the thing is spread out over a huge geographic area. We bought three-day monorail passes and headed to the convention center to get started.
Building the Booths
[Sophi] knows [Ben Unsworth] who put his heart and soul into this year’s IEEE booth. His company, Globacore, builds booths for conferences and this one sounds like it was an exceptional amount of fun to work on. He was part of a tiny team that built a mind-controlled drag strip based on Emotive Insight brainwave measuring hardware shipped directly from the first factory production run. This ties in with the display screens above the track to form a leader board. We’ll have a keen eye out for hacks this week, but the story behind building these booths may be the best hack to be found.
[Ben] told us hands-down the thing to see is the new Oculus hardware called Crescent Bay. He emphatically mentioned The Holodeck which is a comparison we don’t throw around lightly. Seems like a lot of people feel that way because the line to try it out is wicked long. We downloaded their app which allows you to schedule a demo but all appointments are already taken. Hopefully our Twitter plea will be seen by their crew.
In the meantime we tried out the Oculus Gear VR. It uses a Galaxy Note 4 as the screen along with lenses and a variety of motion tracking and user controls. The demo was a Zelda-like game where you view the scene from overhead. This used a handheld controller to command the in-game character with the headset’s motion tracking used to look around the playing area. It was a neat demo, I’m not quite sold on long gaming sessions with the hardware but maybe I just need to get used full-immersion first.
Window to another Dimension
The midways close at six o’clock and we made our way to the Occipital booth just as they were winding done. I’ve been 3D scanned a few times before but those systems used turntables and depth cameras on motorized tracks to do the work. This uses a depth-camera add-on for an iPad which they call Structure Sensor.
It is striking how quickly the rig can capture a model. This high-speed performance is parlayed into other uses, like creating a virtual world inside the iPad which the user navigates by using the screen as if it were a magic window into another dimension. Their demo was something along the lines of the game Portal and has us thinking that the Wii U controller has the right idea for entertainment, but it needs the performance that Occipital offers. I liked this experience more than the Oculus demo because you are not shut off from the real world as you make your way through the virtual.
We shot some video of the hardware and plan to post more about it as soon as we get the time to edit the footage.
Find Us or Follow Us
We’re wearing our Hackaday shirts and that stopped [Josh] in his tracks. He’s here on business with his company Evermind, but like any good hacker he is carrying around one of his passion projects in his pocket. What he’s showing off are a couple of prototypes for a CANbus sniffer and interface device that he’s build.
We’ll be at CES all week. You can follow our progress through the following Twitter accounts: @Hackaday, @HackadayPrize, @Szczys, and @SophiKravitz. If you’re here in person you can Tweet us to find where we are. We’re also planning a 9am Thursday Breakfast meetup at SambaLatte in the Monte Carlo. We hope you’ll stop by and say hi. Don’t forget to bring your own hardware!
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.
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.
The Oculus Rift and all the other 3D video goggle solutions out there are great if you want to explore virtual worlds with stereoscopic vision, but until now we haven’t seen anyone exploring real life with digital stereoscopic viewers. [pabr] combined the Kinect-like sensor in an ASUS Xtion with a smartphone in a Google Cardboard-like setup for 3D views the human eye can’t naturally experience like a third-person view, a radar-like display, and seeing what the world would look like with your eyes 20 inches apart.
[pabr] is using an ASUS Xtion depth sensor connected to a Galaxy SIII via the USB OTG port. With a little bit of code, the output from the depth sensor can be pushed to the phone’s display. The hardware setup consists of a VR-Spective, a rather expensive bit of plastic, but with the right mechanical considerations, a piece of cardboard or some foam board and hot glue would do quite nicely.
[pabr] put together a video demo of his build, along with a few examples of what this project can do. It’s rather odd, and surprisingly not a superfluous way to see in 3D. You can check out that video below.
One of our readers has been playing around with virtual reality lately, and has come up with a pretty cool beta run of his research — virtual interaction using your hands.
Using an Oculus Rift, the Leap Motion controller and a beta run of Unity 4.6, [Tomáš Mariančík] put together a test environment for physical interaction. The Leap Motion controller is capable of tracking your fingers with extremely high detail, which allows him to create a pair of virtual hands inside the test environment that almost perfectly mimic his movements. The hack here is making it all work together.
In the following demo he shows off by interacting with holographic menus, grabbing body parts off of anatomically correct human being (thanks to Unity3D), and manipulating his environment.
