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

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

HandHolo: A Homebrew ARG

Taking a dive into VR or augmented reality — once, dreamed-of science fiction — is not only possible for the average consumer, but crafting those experiences is as well! Hackaday.io user [kvtoet]’s HandHolo is a homebrew method to cut your teeth on peeking into a virtual world.

This project requires a smartphone running Android Oreo as its backbone, a Bluetooth mouse, a piece of cardboard and a small mirror or highly reflective surface. The phone is slotted into the cardboard housing — prototype with what you have! — above the mouse, and the mirror angled opposite the screen reflects the …read more

Magic Leap Finally Announced; Remains Mysterious

Yesterday Magic Leap announced that it will ship developer edition hardware in 2018. The company is best known for raising a lot of money. That’s only partially a joke, since the teased hardware has remained very mysterious and never been revealed, yet they have managed to raise nearly $2 billion through four rounds of funding (three of them raising more than $500 million each).

The announcement launched Magic Leap One — subtitled the Creator Edition — with a mailing list sign up for “designers, developers and creatives”. The gist is that the first round of hardware will be offered for …read more

Racing Simulator Built From Scrapheap Finds

Paradise means something different for everyone, it could be a sitting by a fire on a rainy night or lying on a sun-kissed beach. But for us, and makers like [liltreat4you], it’s a well stocked scrap pile out behind the house. After buying a racing wheel and pedals for his Xbox, he took a trip out to his little slice of paradise and found nearly all the hardware he needed to build a professional looking race simulator. According to his breakdown, most of the money he spent on this build ended up going into that sweet red paint job and …read more

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
