The holy grail of display technology is to replicate what you see in the real world. This means video playback in 3D — but when it comes to displays, what is 3D anyway?
You don’t need me to tell you how far away we are from succeeding in replicating real life in a video display. Despite all the hype, there are only a couple of different approaches to faking those three-dimensions. Let’s take a look at what they are, and why they can call it 3D, but they’re not fooling us into believing we’re seeing real life… yet.
Over the years we have featured a huge array of projects featuring the Raspberry Pi, but among them there is something that has been missing in all but a few examples. The Raspberry P Compute Module is the essentials of a Pi on a form factor close to that of a SODIMM module, and it is intended as a way to embed a Pi inside a commercial product. It’s refreshing then to see [Eugene]’s StereoPi project, a PCB that accepts a Compute Module and provides interfaces for two Raspberry Pi cameras.
What makes this board a bit special is that …read more
You may remember that earlier this year Leap Motion revealed Project North Star, a kind of open-source reference design for an Augmented Reality (AR) headset. While it’s not destined to make high scores in the fashion department, it aims to be hacker-friendly and boasts a large field of view. There’s also an attractive element of “what you see is what you get” when it comes to the displays and optical design, which is a good thing for hackability. Instead of everything residing in a black box, the system uses two forward-facing displays (one for each eye) whose images are …read more
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
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
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
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
[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 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
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
