I’ve got one. Why don’t you?

I got it after realizing making my own hmd was prohibitively expensive, and most of the other commercially available products were seriously lacking in one area or another (resolution vs f.o.v. vs price vs size vs reliable reviews.)
The headplay was a good compromise (for me) though I had to implement my own motion tracking using a ps3 controller. Currently dismantling it for a ben heck inspired virtual boy casemod. Will submit in about a month.
If you are looking to make your own hmd though I suggest you start with the work of Steve Mann…

Severely dated, but incredibly, incredibly brilliant.

sadly, the hmd is no longer available from the manufacturer’s site as a replacement part for $25, but you can still get the whole “spy car” kit off ebay for a little over double that. the hmd takes composite input from a headphone-sized plug that can easily be wired up to the jack for a standard RCA cable.

as the proud owner of one of these (admittedly lo-res) hmds, I’ve got a question for the hackaday crowd: how can I get my laptop (compaq presario 2200, ubuntu hardy) to provide this 320×240 hmd with graphical input? the hmd is connected to the laptop via a rca-vga convertor, and stuff occasionally pops up on the hmd when I change the laptop’s display mode, but telling the laptop to display stuff on the hmd via ubuntu’s screen resolution doesn’t seem to have any lasting effect. any suggestions?

(my goal is to have my laptop take input from a camera mounted on top of the hmd, run that input through my homebrew facial recognition software, and display the output on the hmd.)

It’s like the HMD monocles from the Spygear line, 320×240 B&W kopin, but they went the other way, with cheaper and bulkier (I suspect) optics instead.

I forgot about headplay, technology looks interesting. It appears that they may actually be running a “true” 800×600 display instead of (800×600)/3 of a typical color masked LCD. It looks to use a projector type technology(LCOS), as it has 120Hz framerate, but 360 color fields per second, so each color gets its own full field. Should be OK if they’re using RGB LEDs like they should be (although hilarious if they had a spinning color wheel in there!). This also explains why you MUST use their external box, it needs very special drivers. They just had spare horses so they provided a mini media player inside. Hmmm… technically, this technology should scale linearly with DLP projector prices and color capability.

For daily use, however, I believe you either need a translucent display (Heads up Display) or a sidelook display (Heads Down Display). If you can’t operate with the HMD on, what’s the point? The myvu comes close, and will probably cause the least nausea. They focused on making the framework around the display translucent so you don’t get as disoriented as normal HMDs. A lightweight sidelooker for the non-eyeglass crowd is the eyetop.

If you want just a single HUD, the Kopin site is the best way to buy single displays of any rez. Otherwise, canabalize! (my motto).

Framed versus frameless- the framed versions have a plastic bezel around them to protect the edges and fill space to mount to camcorders/consumer gadets better, the frameless versions are the barebones glass-ended displays with no protection bezel- as big as the display itself is what you get on a ribbon cable.

Basically, yeah, the same 640×480 module unit is used in both of these HMDs in the review, and you can buy it for 240$ bare from Kopin, and make your own frame from stratch, via shapelock molding, lost wax casting, etc. Save money, and get the smallest possible form factor for hacking it into another device!

Hope that helps.

they list it in the low volume ( i assume its one uinit too) as
VGA $240 KCD-VDCF-BA Framed
just dont know what they mean by “Framed”? does this mean you get the whole thing just without the Myvu Crystal printed on the side? or the bare guts?
