HMD Upgrade

[Banfield Design] has put together this instructable on how to upgrade or re build a head mounted display to be more immersive and add features.  Though you can already buy glasses style viewers for your media devices, they can use some upgrades. For one, you have to supply your own sound, and putting headphones on, over bulky glasses can be painful on your ears. Another area that could use improvement is the light that comes in around the glasses. The current trend is to make them as small as possible, but that tends to let your peripheral vision see the outside world. [Banfield design] wanted to make them more immersive, so he built them into some ski goggles. This not only helped block the light, but allowed for an over the ear style headphone assembly which is much easier on the ears.

A functional improvement came next, by adding a webcam front and center. He could now switch between a live feed of his environment and whatever other inputs he wanted. This could be really fun with some augmented reality. He has a list of future improvements, but he doesn’t mention adding a second camera for stereoscopic viewing of his surroundings. Why would you do that? because it would make augmented reality much cooler.

CES: Augmented Reality

[youtube=http://www.youtube.com/watch?v=tB-kZmq0syc]

I got my hands on a set of augmented reality glasses that were displayed with a Monkey-Ball style game. This wasnt anything too new as far as the augmented reality goes, however the glasses that were used with the game featured stereo cameras on the center of the outside of the lens, which allowed a true 3D augmented vision that you wouldn’t have to stare into a screen for. These glasses were still in the demo stage, but if they ever make it out into retail, I think that they would be exactly what could bridge AR from a fun toy to a useful tool. Another review video after the break.

Scan Room, Explore Virtually

[Patrick] directed us to his project for alternate realism. The final goal is to be able to walk around in a space wearing a head mounted display, exploring a virtual representation of that space. This virtual representation could be altered, stylized, augmented and modified in countless ways. It is an exploration in perception, similar to enjoying different styles of painting, we could enjoy different styles of viewing a real space. Currently, it isn’t quite real time. He has to scan a room with a somewhat bulky device, then plug into his display to explore it. Being able to scan quickly and reliably enough shouldn’t be far off. [Patrick] notes that others have done almost real time scans at home already.

Head-mounted Computer With Spit, Bailing Wire

Oh, for crying out loud! While we were all giddy reporting on yesterday’s wonderfully done head-mounted computer, [Andrew Lim] of recombu.com comes along and essentially does the same thing with an HTC Magic handset and three dollars worth of Harbor Freight crap. Linux kernel, WiFi, accelerometer, the whole nine yards. Consider our collective ass handed to us.

Funny thing is, either of these could be considered The Consummate Hack. One flaunting the creator’s know-how with its custom-designed parts and delicate engineering, the other exhibiting a more punk flair with random scraps and off-the-shelf technology achieving much the same effect — a solution so obvious we were blind to it. Whatever your outlook, this is a great day to be a hacker!

Head-mounted Computer With Linux, WiFi

hmdlinux

Most wearable computers we’ve seen feature a head-mounted display tethered to a small PC system in a backpack or worn on a belt. Here’s a slick little system that does away with the cord, fitting the entire system in the glasses.

[Pascal Brisset’s] WXHMD is based on the tiny Gumstix Overo Fire computer-on-module which features a beefy, 3D-capable OMAP processor that runs Linux. The Gumstix is interfaced with a Vuzix VR920 head-mounted display that includes a three-axis accelerometer and compass. Tying these together is a custom video digital-to-analog converter board of [Pascal’s] own design, created using direct-to-PCB inkjet printing techniques. For less than $1,000 total in parts, the result is a spatially aware six ounce computer, with display and battery and all, that fits neatly over the bridge of one’s nose.

It’s a fantastic hack and a nicely documented project, though even the device’s creator himself questions whether having a pair of microwave transceivers and a LiPo battery strapped directly over one’s eyes and brain is such a good idea.

Monocular Head Mounted Display

glasses

[Xenonjon] wanted to make a Heads Up Display that he could use while maintaining the ability to see. The most logical choice was a monocular set up.  He had an old Eye-Trek laying around and decided to sacrifice it to make his Heads Up Display. Combining a screen from his TV glasses and a wireless security camera setup, he was able to achieve an untethered monocular HUD. This has a multitude of uses, from displaying vital information, to home made night vision, or just watching TV while you work.

There’s plenty of good pictures and information there. The final result is a pair of safety glasses with the display and a pack that you have to put on your belt that holds batteries and the wireless receiver.  It seems as though it isn’t horribly cumbersome, but we’d have to try it for a while to say if it would be ergonomically sound.

Wearable Project Inspiration

Yesterday, Gizmodo published a roundup of wearable gadgets for people who “don’t mind looking like a tool”. It’s interesting to see what has been deemed commercially viable and put into mass production. The list covers HMDs, embedded WiFi detectors, integrated keyboards, tech jackets, speaker hats, and others. We thought you might find some inspiration from the list for your next project. In the past, we embedded a WiFi detector in a backpack strap for our Engadget how-to. The natural choice for wearable projects is the LilyPad Arduino which was featured most recently in the turn signal jacket.
