Hacked Headset Brings VR to the Commodore 64

The venerable Commodore 64 got a lot of people started in computers, and a hard core of aficionados keeps the platform very much alive to this day. But a C64 just doesn’t have the horsepower to do anything more than some retro 8-bit graphics games, right?

Not if [jim_64] has anything to say about it. He’s created a pair of virtual-reality goggles for the C64, and the results are pretty neat. Calling them VR is a bit of a stretch, since that would imply the headset is capable of sensing the wearer’s movements, which it’s not. With just a small LCD screen tucked into the slot normally occupied by a smartphone in the cheap VR goggles [jim64] used as a foundation for his build, this is really more of a 3D wearable display — so far. The display brings 3D-graphics to the C64, at least for the “Street Defender” game that [jim64] authored, a demo of which can be seen below. We’ll bet position sensing could be built into the goggles to control the game too. Even then it won’t be quite the immersive (and oft-times nauseating) experience that VR has become, but for a 35-year old platform, it’s not too shabby.

Looking for more C64 love? We’ve got a million of ’em — case mods, C64 laptops, tablets, even CPU upgrades.

CastAR Shuts Doors

Polygon reports CastAR is no more.

CastAR is the brainchild of renaissance woman [Jeri Ellsworth], who was hired by Valve to work on what would eventually become SteamVR. Valve let [Jeri] go, but allowed her to take her invention with her. [Jeri] founded a new company, Technical Illusions, with [Rick Johnson] and over the past few years the CastAR has appeared everywhere from Maker Faires to venues better focused towards innovative technologies.

In 2013, Technical Illusions got its start with a hugely successful Kickstarter, netting just north of one million dollars. This success drew the attention of investors and eventually led to a funding round of $15 million. With this success, Technical Illusions decided to refund the backers of its Kickstarter.

We’ve taken a look a CastAR in the past, and it’s something you can only experience first-hand. Unlike the Oculus, Google Cardboard, or any of the other VR plays companies are coming out with, CastAR is an augmented reality system that puts computer-generated objects in a real, physical setting. Any comparison between CastAR and a VR system is incomplete; these are entirely different systems with entirely different use cases. Think of it as the ultimate table top game, or the coolest D&D game you could possibly imagine.

You’re the Only One not Playing with Unity

It wasn’t too long ago that one could conjecture that most hackers are not avid video game players. We spend most of our free time taking things apart, tinkering with microcontrollers and reading the latest [Jenny List] article on Hackaday.com. When we do think of video games, our neurons generally fire in the direction of emulating a console on a single board computer, such as a Raspberry Pi or a Beaglebone. Or even emulating the actual console processor on an FPGA. Rarely do we venture off into 3D programs meant to make modern video games. If we can’t export an .STL with it, we’re not interested. It’s just not our bag.

Oculus Rift changed this. The VR headset was originally invented for 3D video games, but quickly became a darling to hackers the world over. Virtual Reality technology is far bigger than just video games, and brings opportunity to many fields such as real estate, construction, product visualization, education, social interaction… the list goes on and on.

The Oculus team got together with the folks over at Unity in the early days to make it easy for video game makers to make content for the Rift. Unity is a game engine designed with a shallow learning curve and is available for free for non-commercial use. The Oculus Rift can be integrated into a Unity environment with the check of a setting and importing a small package, available on the Oculus site. This makes it easy for anyone interested in VR technology to get a Rift and start pumping out content.

Hackers have taken things a step further and have written scripts that allow Unity to communicate with an Arduino. VR is fun. But VR plus physical reality is just down right exciting! In this article, we’re going to walk you through setting up your Oculus Rift and Unity game engine to communicate with the outside world via an Arduino.

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 camera.

To gel everything together, he adds motion tracking to his already extensively developed software stack, which enables him to unshackle the Daydream controller from Android. He deciphers the Bluetooth packets and streams the sensory information straight to a web browser over a webSocket connection.

The results are quite impressive and the tracking is smooth. Not only does this add to the final goal of hacking his way towards a platform independent VR motion controller, he aptly gets some inspiration from Sony, extends Google’s hardware and even manages to use Apple’s webcam along the way. How’s that for carving passages between the walled gardens of consumer electronics?

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 environment isn’t new, but anchoring that virtual environment into the real world in a way that two very different headsets share is interesting to see. [Drew] says that the real challenge wasn’t just getting the different hardware to talk to each other, it was how to give them both a shared understanding of a common space. [Drew] needed a way to make that work, and you can see the results in the video embedded below.

Vive Tracker Brings Easier VR Hacking

CES 2017 is over and there were VR gadgets and announcements aplenty, but here’s an item that’s worth an extra mention because it reflects a positive direction we can’t wait to see more of. HTC announced the Vive Tracker, to be released within the next few months.

The Tracker looks a bit like a cross between a hockey puck and a crown. It is a self-contained, VR trackable device with a hardware port and built-in power supply. It can be used on its own or attached to any physical object to make that object trackable and interactive in VR. No need to roll your own hardware to interface with the Vive’s Lighthouse tracking system.

Valve have been remarkably open about the technical aspects of their hardware and tracking system, and have stated they want to help people develop their own projects using the system. We’ve seen very frank and open communication on the finer points of what it took to make the Lighthouse system work. Efforts at reverse-engineering the protocol used by the controller even got friendly advice. For all the companies making headway into VR, Valve continues to be an interesting one from a hacking perspective.

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!
