Troy New York’s Tech Valley Center of Gravity is following up their January IoT Hackathon with another installment. The April 16-17 event promises to be a doozy, and anyone close to the area with even a passing interest in gaming and AR/VR should really make an effort to be there.
Not content to just be a caffeine-fueled creative burst, TVCoG is raising the bar in a couple ways. First, they’re teaming up with some corporate sponsors with a strong presence in the VR and AR fields. Daydream.io, a new company based in the same building as the CoG, is contributing a bunch of its Daydream.VR smartphone headsets to hackathon attendees, as well as mentors to get your project up and running. Other sponsors include 1st Playable Productions and Vicarious Visions, game studios both located in the Troy area. And to draw in the hardcore game programmers, a concurrent Ludum Dare game jam will be run by the Tech Valley Game Space, with interaction and collaboration between the AR/VR hackers and the programmers encouraged. Teams will compete for $1000 in prizes and other giveaways.
This sounds like it’s going to be an amazing chance to hack, to collaborate, and to make connections in the growing AR/VR field. And did we mention the food? There was a ton of it last time, so much they were begging us to take it home on Sunday night. Go, hack, create, mingle, and eat. TVCoG knows how to hackathon, and you won’t be disappointed.
Thanks to [Duncan Crary] for the heads up on this.
The web is abuzz with the news that the Facebook-owned Oculus Rift has buried in its terms of service a clause allowing the social media giant access to the “physical movements and dimensions” of its users. This is likely to be used for the purposes of directing advertising to those users and most importantly for the advertisers, measuring the degree of interaction between user and advert. It’s a dream come true for the advertising business, instead of relying on eye-tracking or other engagement studies on limited subsets of users they can take these metrics from their entire user base and hone their offering on an even more targeted basis for peak interaction to maximize their revenue.
Hardly a surprise you might say, given that Facebook is no stranger to criticism on privacy matters. It does however represent a hitherto unseen level of intrusion into a user’s personal space, even to guess the nature of their activities from their movements, and this opens up fresh potential for nefarious uses of the data.
Fortunately for us there is a choice even if our community doesn’t circumvent the data-slurping powers of their headsets; a rash of other virtual reality products are in the offing at the moment from Samsung, HTC, and Sony among others, and of course there is Google’s budget offering. Sadly though it is likely that privacy concerns will not touch the non-tech-savvy end-user, so competition alone will not stop the relentless desire from big business to get this close to you. Instead vigilance is the key, to spot such attempts when they make their way into the small print, and to shine a light on them even when the organisations in question would prefer that they remained incognito.

If you’re looking for a quick and easy project to get into virtual reality, making your own VR skateboard controller is actually pretty easy to do!
First you’ll need some kind of VR headset. You could buy a fancy one, like the Oculus, or a Samsung Gear VR — or you could use something as simple as Google Cardboard — and you could even make your own. All it takes is a phone, an Arduino, a Bluetooth module, and an accelerometer-plus-gyroscope IMU.

In Star Trek IV: The Voyage Home, the usually unflappable Spock found himself stumped by one question: How do you feel? If researchers at the University of Memphis and IBM are correct, computers by Spock’s era might not have to ask. They’d know.
[Pouya Bashivan] and his colleagues used a relatively inexpensive EEG headset and machine learning techniques to determine if, with limited hardware, the computer could derive a subject’s mental state. This has several potential applications including adapting virtual reality avatars to match the user’s mood. A more practical application might be an alarm that alerts a drowsy driver.

A lot of people got drones for Christmas this year (and many Hackaday readers already had one, anyway). A lot of these drones have cameras on them. The expensive ones beam back live video via RF. The cheaper ones just record to an SD card that you can download later.
If you are NASA, of course, this just isn’t good enough. At the Langley Research Center in Virginia, they’ve been building the Greased Lightning (also known as the GL-10) which is a 10-engine tilt-prop unmanned aerial vehicle. The carbon fiber drone is impressive, sure, but what wows is the recent video NASA released (see below).

Think of Virtual Reality and it’s mostly fun and games that come to mind. But there’s a lot of useful, real world applications that will soon open up exciting possibilities in areas such as medicine, for example. [Victor] from the Shackspace hacker space in Stuttgart built an Augmented Reality Ultrasound scanning application to demonstrate such possibilities.
But first off, we cannot get over how it’s possible to go dumpster diving and return with a functional ultrasound machine! That’s what member [Alf] turned up with one day. After some initial excitement at its novelty, it was relegated to a corner gathering dust. When [Victor] spotted it, he asked to borrow it for a project. Shackspace were happy to donate it to him and free up some space. Some time later, [Victor] showed off what he did with the ultrasound machine.
As soon as the ultrasound scanner registers with the VR app, possibly using the image taped to the scan sensor, the scanner data is projected virtually under the echo sensor. There isn’t much detail of how he did it, but it was done using Vuforia SDK which helps build applications for mobile devices and digital eye wear in conjunction with the Unity 5 cross-platform game engine. Check out the video to see it in action.

[Alvaro Ferrán Cifuentes] has built the coolest motion capture suit that we’ve seen outside of Hollywood. It’s based on tying a bunch of inertial measurement units (IMUs) to his body, sending the data to a computer, and doing some reasonably serious math. It’s nothing short of amazing, and entirely doable on a DIY budget. Check out the video below the break, and be amazed.
Cellphones all use IMUs to provide such useful functions as tap detection and screen rotation information. This means that they’ve become cheap. The ability to measure nine degrees of freedom on a tiny chip, for chicken scratch, pretty much made this development inevitable, as we suggested back in 2013 after seeing a one-armed proof-of-concept.
But [Alvaro] has gone above and beyond. Everything is open source and documented on his GitHun. An Arduino reads the sensor boards (over multiplexed I2C lines) that are strapped to his limbs, and send the data over Bluetooth to his computer. There, a Python script takes over and passes the data off to Blender which renders a 3D model to match, in real time.
All of this means that you could replicate this incredible project at home right now, on the cheap. We have no idea where this is heading, but it’s going to be cool.
