iPod VR Mashup


Someone built an iPod VR display. Okay mayby "built" is a bit strong, all he did was connect it to the video iPod's AV cables and took a bunch of pictures of himself.

I've wondering if small portable video devices will eventually spark the VR / LCD goggles you always see in the future sci-fi movies.

Well, I support that. I do think the iPod is one of the most influential wearable computers at the moment. Plus he also wants to build a VR glove controller for his video iPod.

Removable HMD for Glasses


Man, I wish I grok'd Japanese. This removable HMD for glasses looks pretty sweet. One of my problems is that I wear glasses, and I would prefer to have an HMD that rides on top of them.

List of HMD & VR helmets


Christoph Bungert has made a list of HMD and VR helmets, which lists things like price, resolution, number of panels, and more. I think this is the kind of community resource that really helps people who are interested in working with mediated reality / augmented vision.

The only thing it's missing is editorials!

Microvision Ruggerdizing Military HMDs

Microvision recently received a $740,000 subcontract to help ruggerdize their helmet based head mounted displays, which are currently used by the U.S. military. It looks like the military is taking to wearable technology quite well, and want the same kind of durability they get from their other tools.
Under the contract, Microvision will deliver prototypes that meet or exceed military standards. General Dynamics C4 Systems awarded the subcontract.

Here's a video of their current military gear.

Eyetop HMD with Camera


The Eyetop Camera is an Head Mounted Display with a 752x582 resolution video camera on the side. It uses PAL/NTSC and gets 25 frames a second.

Eyetop Camera incorporates a professional rugged aluminum video camera and LED system into the frame of the best-selling Eyetop Classic ‘video glasses.’ .You can film what you see and control it with the monitor embedded in the lens of the glasses, or even get another set of information on that high-quality active matrix LCD screen from any external video source.

Okay so at this point, you're probably like me, drooling on your keyboard, wondering what members of your family you can sell into slavery in order to get one of these. Well that's where Nicolas from Eyneo comes in:

That product was for sale at $4,000+ and is out of stock now. It will be replaced with a new version at far lower price point first semester 06. Price unknown today. Thanks, nicolas

Well I guess my family members and girlfriend are safe... for now.

Wild Planet Night Vision Toy

Here's a review of WildPlanet's "Infra-Red Nightvision Goggles". I had seen these before, but after trying out the "Eye-Link Communicators" from the same company and being a bit disapointed, I wasn't about to go spend $80 on another potentially too small, not useful enough wearable computing spy toy. I then read about this other guy who is currently hacking his, and it sounds somewhat promising!

I recently purchased one of [the IR Nightvision Goggles]. From what research I've done so far, it is a pretty good candidate for hacking into a fairly low-end eyetap/wearable display.

Comfort-wise, it's not great, but it is a lot better than the Cybermaxx displays from days of old. There are plenty of spots here more padding could be attached to make it more comfortable. The batteries are in a belt pack, and the headpiece connects to them via what looks like a standard power connector.

The camera is fixed-focus, and is surrounded by a ring of IR LEDs. These cannot be turned off without modifying the device or turning the whole thing off. They tend to wash out the view in normal indoor lighting conditions, but only in a spot in the middle.

The display itself appears to be a kopin cyberdisplay with a yellow-green LED backlight. The backlight is a surface mount LED on its own small PCB behind the display, so replacing it with something a bit less bilious is fairly simple.

Tekgear sells a white LED backlight ( for 28
that might fit. I haven't tried it.

The driver chip is a MCVVQ111, apparently the FB version. According to other posts on [the wear-hard list]:

"MCVVQ111FB is a MOS8 device MOS8 has already closed down. MCVVQ111AFB is MOS20 device and is a replacement for MCVVQ111FB.[...] Please note that the loop filter of MCVVQ111AFB on pin 7 is different from that of MCVVQ111FB."

According to freescale semiconductor:

" The MCVVQ111 VirtuoVue Monochrome Video Display is designed to accept a standard monochrome video signal (525 or 625 lines), and convert it for display on the CyberDisplay320 LCD Display Panel. [...] A separate OSD input is provided."

The camera in the night vision monocle is on a separate board from the display driver chip. They are connected by a four pin cable that includes power, ground, and (I assume) video signal and video ground. At any rate, there is not another chip to render a proprietary signal into standard video, so I assume that the camera outputs standard video. I'll be checking into this over the next week or so.

There are at least two ways you could make this into an eyetap.

The first is by disconnecting the video output from the camera, routing it to a computer, doing some processing, and then sending it back to the display board. This is probably better, as it would allow some scaling of the image to match what the other eye sees. As manufactured, the image on the display is smaller than life, so the effect is somewhat like looking through a telescope backwards with one eye while having the other eye open.

The second is by hooking into the OSD connections of the cyberdisplay driver chip and using the built-in OSD input. This is probably less optimal, as you would need to hook up an OSD generator, connect to a very tiny pin on the chip, etc.

Of course, if you don't want an eyetap, then you still have a very small display, driver board, and camera with IR LEDs, all for ~$80.

I hope it works out well!

Covert Eyetap For Sale



Someone's selling their covert head mounted display. Might be worth getting since most of the commercial HMDs out there are so geeky.

I am willing to sell this prototype for $1200, I will include documentation of my previous efforts as well as an upgrade that I never went through with (that gives more eye clearance and moves the screen closer to the center of your vision by relocated the connector board using spare hirose connectors that eMagin is willing to supply at about $3 each).

Keep in mind that this display is a true 800x600 pixel 24 bit color display.

This prototype gets its signal from a VGA cable. And it gets power from any USB

For this kind of cash though, I'd probably make sure you can get your money back if it isn't what you want.

HMD for Swimmers

"When you're swimming, remembering how many lengths you've swum can be hard. I know that when I used to swim, I would trick myself into thinking I'd done 25 laps when maybe I'd only done 20," she says.

Williams' system incorporates an electronic device, which houses a compass, at the back of the headstrap on the goggles.

When the swimmer turns, the compass detects that the co-ordinates have changed and registers the time.

The information, including the total time spent swimming, the number of laps completed and the speed traveled are shown in a tiny heads-up display inside the goggle lens, using a system that reflects information off tiny mirrors. [CNN]

Olympus’s See-Thru HMD


Yet another HMD, luckily this one is really targeted at the wearable market instead of the videophone market.

"[It has a] 3.8-inch translucent screen with a diagonal length of 10 cm seems to exist 50 cm ahead of the user."

It also weighs 27g, so not too bad considering.

Mobile Phone Video HMD

This HMD is designed by France Telecom for Orange mobile phone users, and is basically designed for watching video. Even though it's designed for watching movies and TV while standing in line at the bank, I'm up for anything that will help HMDs get adopted in the marketplace. Just because it's designed for video doesn't mean it has to do video.

It also has headphones, and weighs 70 grams. Due to come out in October of this year.

MicroOptical Interview

microoptical.jpgPretty tame interview with MicroOptical Marketing Vice President Mark Basler. Not very noteworthy, except for the following passage:

"We've talked to a lot of wireless telecom executives, and they're very interested in replacing cell phone displays with these kinds of glasses," Basler says. "These companies want to be able to sell consumers more and more display-intensive functions that will use up air time, but in order to do that they'd have to make the handsets so big that no one would buy them. That's where we come in." Possible partners also include phone makers like Motorola, Nokia and Samsung.

Automotive HMD

nomad_hud.jpgMicroVision has introduced a new head mounted display for $4,000, which is being marketed towards automotive service enviornments. This means that your local grease monkey may be wearing one of these devices, if you own a porche.

The system lays schematics on top of what you would normally see, and uses 802.11b wireless to connect as a thin client to the shop's server to pull schematics. They also say you can view webpages over the monocromatic display, but somehow I think this might not be the ideal way to surf the web.

Eye Link & M1OEM Kit Hack

Tony Havelka wrote to the wear-hard mailing list about a hack from TekGear using the Eye Link Communicator, a kid's toy that I've written about on here before, and their M1 OEM Kit. TekGear's Lily Bergen has described a cheap way to make use of their OEM kit for their 320x240 grayscale HMD ($375USD), which is not very useful without a viewfiender and casing. Hopefully this will not be the first hack of the Eye Link Communicator.

It is likely that for many people, TekGear's Ingineo Eye Top is a better solution to the low end HMD market at $449USD. At least for people who don't wear glasses already.

In related news, TekGear is publishing a monthly newsletter. How neat! It's basically a platform for their products, but I love their high end geek swag, and hopefully this will help provide information to our community.

Prototype HMD/POV cam from Motorola and Frog Design

In Time's new article, Coolest Inventions for 2003, they profile a device from Motorola and Frog Design which part of their Offspring Wearable prototypes. It's odd that Time would list a device that isn't really available, but it is quite cool. It houses a digital pinhole camera above the right lens, a miniature display on the inside of the left lens, and an ear piece that pops out the side. They intend to market this as a cell phone accessory available for the public in 2006.

I for one applaud a major hardware manufacturer such as Motorola to produce a Head Mounted Display with a Point Of View Camera included. The design looks pretty nice too, but I hope they anticipate their male market as well as their female consumers.

Three years seems like a long time to wait to buy this gadget, but since it's a Motorola product, HMDs and POV cams are going to be commonplace when it is available to the public.

In addition, if you're interested in exoskeletons, check Time's bit in this article about Keijiro Yamamoto's Power Suit, which uses air power to augment your strength. Costs 15-20k, so only sutiable for rich gargoyles.

Update (Nov 10th, 4:53PM):
This turns out to be the same prototype that was popularized a while ago with a variety of other wearable toys, all of which utilize bluetooth to communicate. I also really like the wearable camera they are producing, although it's not nearly as sweet as the POV cam in the shades.

From PhoneScoop:
Goggles: Integrated into the frame of exciting,
stylish sports eyewear, this device incorporates a
heads-up display, digital camera, ear bud and
microphone. Due to the power requirements, there is a
tethered cord that runs out the back to an external
power supply. You can view 800 X 600 displays while
simultaneously staying in touch with the world around
