Homebrew Linear Actuators Put The Moves On This Motion Simulator

Breaking into the world of auto racing is easy. Step 1: Buy an expensive car. Step 2: Learn how to drive it without crashing. If you’re stuck at step 1, and things aren’t looking great for step 2 either, you might want to consider going with a virtual Porsche or Ferrari and spending your evenings driving virtual laps rather than real ones.

The trouble is, that can get a bit boring after a while, which is what this DIY motion simulator platform is meant to address. In a long series of posts with a load of build details, [pmvcda] goes …read more

This Is Your Solution For Open Source Motion Tracking

The HTC Vive Tracker adds real-world objects to your virtual world. While these real-world objects in virtual environments are now mostly limited to a Nintendo Zapper for a Duck Hunt clone and a tennis racket, the future is clear: we’re going to be playing Duck Hunt and Wii Sports while wearing headsets. The future is so bright, it burns.

Of course, with any piece of neat computing hardware, there’s an opportunity for building an Open Source clone. That’s what [Drix] is doing with his Hackaday Prize entry. He’s created an Open Source Vive Tracker. It’s called the HiveTracker, and it …read more

A Mobile Computer to Make William Gibson Jealous

The personal computers in science fiction books, movies, and games are way cooler than the dinky pieces of hardware we’re stuck with in the real world. Granted the modern laptop has a bit more style than the beige boxes of yesteryear, but they still aren’t half as l33t as the custom PowerBooks in Hackers. Luckily for those who dream of jacking into the Matrix, the average hacker now has access to the technology required to make a custom computer to whatever fanciful specifications they wish.

A perfect example is this “cyberdeck” created by [Tinfoil_Haberdashery]. Inspired by William Gibson’s Neuromancer, …read more

N64 Emulated in VR Makes Hyrule go 3D

The Nintendo 64 had some groundbreaking and popular 3D games, and [Avaer Kazmer] felt it was only right to tamper with things just enough to trick an emulator into playing Ocarina of Time in VR, complete with stereoscopic 3D. The result is more than just running an emulator on a simulated screen in virtual reality; the software correctly renders a slightly different perspective of the world of Hyrule to each eye in order to really make the 3D pop in a way the original never could, and make it playable with VR controllers in the process. The VR emulator solution …read more

Redirected Walking in VR done via Exploit of Eyeballs

[Anjul Patney] and [Qi Sun] demonstrated a fascinating new technique at NVIDIA’s GPU Technology Conference (GTC) for tricking a human into thinking a VR space is larger than it actually is. The way it works is this: when a person walks around in VR, they invariably make turns. During these turns, it’s possible to fool the person into thinking they have pivoted more or less than they have actually physically turned. With a way to manipulate perception of turns comes a way for software to gently manipulate a person’s perception of how large a virtual space is. Unlike other methods …read more

Leap Motion Announces Open Source Augmented Reality Headset

Leap Motion just dropped what may be the biggest tease in Augmented and Virtual Reality since Google Cardboard. The North Star is an augmented reality head-mounted display that boasts some impressive specs:

  • Dual 1600×1440 LCDs
  • 120Hz refresh rate
  • 100 degree FOV
  • Cost under $100 (in volume)
  • Open Source Hardware
  • Built-in Leap Motion camera for precise hand tracking

Yes, you read that last line correctly. The North Star will be open source hardware. Leap Motion is planning to drop all the hardware information next week.

Now that we’ve got you excited, let’s mention what the North Star is not — it’s …read more

Firefox Reality, A Browser For VR Devices

The browser you are reading this page in will be an exceptionally powerful piece of software, with features and APIs undreamed of by the developers of its early-1990s ancestors such as NCSA Mosaic. For all that though, it will very probably be visually a descendant of those early browsers, a window for displaying two-dimensional web pages.

Some of this may be about to change, as in recognition of the place virtual reality devices are making for themselves, Mozilla have released Firefox Reality, in their words “a new web browser designed from the ground up for stand-alone virtual and augmented …read more

What We Need To Try In Haptic Hacks

Looking for ideas for your haptics projects? [Destin] of the Smarter Every Day YouTube channel got a tour from the engineers at HaptX of their full-featured VR glove with amazing haptic feedback both with a very fine, 120-point sense of touch, force feedback for each finger, temperature, and motion tracking.

In hacks, we usually stimulate the sense of touch by vibrating something against the skin. With this glove, they use pneumatics to press against the skin. A single fingertip has multiple roughly 1/8 inch air bladders in contact with it. Each bladder is separately pneumatically controlled by pushing air into …read more

Google Light Fields Trying to Get the Jump on Magic Leap

Light Field technology is a fascinating area of Virtual Reality research that emulates the way that light behaves to make a virtual scene look more realistic. By emulating light coming from multiple angles entering the eye, the scenes look more realistic because they look closer to reality. It is rumored to be part of the technology included in the forthcoming Magic Leap headset, but it looks like Google is trying to steal some of their thunder. The VR research arm of the search giant has released a VR app called Welcome to Light Fields that uses a similar technique on …read more

Reverse Engineering Opens Up the Samsung Gear VR Controller

We love a bit of reverse engineering here at Hackaday, figuring out how a device works from the way it communicates with the world. This project from [Jim Yang] is a great example of this: he reverse-engineered the Samsung Gear VR controller that accompanies the Gear VR add-on for their phones. By digging into the APK that links the device to the phone, he was able to figure out the details of the Bluetooth connection that the app uses to connect to the device. Specifically, he was able to find the commands that were used to get the device to …read more
