Immersive VR with a 200-Degree Stereoscopic Camera

VR is in vogue, but getting on board requires a steep upfront cost. Hackaday.io user [Colin Pate] felt that $800 was a bit much for even the cheapest commercial 360-degree 3D camera, so he thought: ‘why not make my own for half that price?’

[Pate] knew he’d need a lot of bandwidth and many GPIO ports for the camera array, so he searched out the Altera Cyclone V SOC FPGA and a Terasic DE10-Nano development board to host it. At present, he has four Uctronics OV5642 cameras on his rig, chosen for their extensive documentation and support. The camera mount …read more

Soon You’ll Sit Inside a Robot’s Head at Work

MIT’s Computer Science and Artificial Intelligence Lab, CSAIL, has created a process of teleoperating a Baxter humanoid robot with an Oculus Rift VR headset. This project is partially aimed towards making manufacturing jobs a hell of a lot of fun telecommutable. It could even be a way to supervise robot workers from a distance.

In a nutshell, the user controls the robot remotely in a virtual reality environment. The user does this specifically in a VR environment modeled like a control room with multiple sensor displays, making it feel like they are sitting inside the robot’s head. By using hand …read more

Low-Tech Chair Enters the Matrix

This video demonstrates a really interesting experiment: sticking a Vive Tracker onto an ordinary chair in order to sync it up perfectly with its VR counterpart. The result? A chair that is visible in VR as a virtual object, but has a 1:1 physical world version occupying the same space. This means that unlike any other virtual object, this chair can be seen, touched, felt, moved, and actually sat in while the user is immersed in VR.

The purpose of this experiment seems to have been to virtually explore seating arrangements for real-world environments, and spawned a theatre planning tool …read more

Cheap And Easy Motion Tracking

[Koppany Horvarth] set out to create a dirt-cheap optical tracking rig for VR that uses only two cameras and a certain amount of math to do its thing. He knew he could do theoretically, and wouldn’t cost a lot of money, but still required a lot of work and slightly absurd amount of math.

While playing around with a webcam that he’d set up to run an object-tracking Python script and discovered that his setup tended to display a translucent object with a LED inside of it as pure, washed-out white. This gave [Koppany] the idea that he could use …read more

VR and Back Again: An XRobots Tale

Our friend [James Bruton] from XRobots has engaged in another bit of mixed-reality magic by showing how one can seamlessly step from the virtual world into the real world, and back again. Begone, green screens and cumbersome lighting!

Now, most of what you’re seeing is really happening in post-production — for now — but the test footage is the precursor for a more integrated system down the road. As it works now, a GoPro is attached to the front of a HTC Vive headset, allowing [Bruton] to record in both realities at the same time. In the VR test area …read more

Take A Bicycle Tour Anywhere In The World

Imagine yourself riding through the countryside of Tuscany in the morning, then popping over to Champagne for a tour in the evening without taking a plane ride in the intermission. In fact, you don’t have to leave your living room. All you need is a stationary bicycle, a VR headset, and CycleVR.

[Aaron Puzey] hasn’t quite made the inter-country leap quite like that, but he has cycled the entire length of the UK, from its southern point to its northernmost tip. The 1500km journey took 85 hours over the course of eight months to complete.

CycleVR is actually a VR …read more

Ping Pong Ball Improves the Google Daydream Controller

[Matteo] has just released a new installment of his Google Daydream VR controller hack, which we first covered last year (when he got it working with iOS). This time around he’s managed to forge a half Daydream, half PlayStation Move controller hybrid.

The original controller only managed a mere 3 DOF (Degrees of Freedom) using the internal accelerometer; although this conveyed rotational motion around the 3 axis, transitional information was completely lacking. [Matteo] resolves this by forming a simple positional marker out of a white LED enclosed in a standard ping pong ball; He tracks this setup using an iSight …read more

Sharing Virtual and Holographic Realities via Vive and Hololens

An experimental project to mix reality and virtual reality by [Drew Gottlieb] uses the Microsoft Hololens and the HTC Vive to show two users successfully sharing a single workspace as well as controllers. While the VR user draws cubes in midair with a simple app, the Hololens user can see the same cubes being created and mapped to a real-world location, and the two headsets can even interact in the same shared space. You really need to check ou the video, below, to fully grasp how crazy-cool this is.

Two or more VR or AR users sharing the same virtual …read more

David Krum: The Revolution in Virtual Reality

[David Krum] is associate lab director at the Mixed Reality Lab at the Institute for Creative Technologies at USC. That puts him at the intersection of science and engineering: building cool virtual reality (VR) devices, and using science to figure out what works and what doesn’t. He’s been doing VR since 1998, so he’s seen many cool ideas come and go. His lab was at the center of the modern virtual reality explosion. Come watch his talk and see why!

What is Virtual Reality, Really?

We all know what VR is, right? It’s that trope in sci-fi where you’re stuck …read more

Making VR Controllers From The Ground Up

VR is going to be the next big thing in five to seven years, and with that comes the problem of what the controllers will look like. The Vive and PS Move are probably close to what the first successful consumer VR setup will look like, but there’s plenty of room for experimentation. [ShinyQuagsire] decided to experiment with VR, IMUs, and computer vision and managed to make a VR controller from the ground up.

The design of [Quagsire]’s VR controller is very similar to the PS Move controller: there’s a glowy ball on top of a Wii-nunchuckish controller. There’s a …read more
