GVD300-N ($99) Non-stereoscopic LCD glasses (400x225x2) Gyromouse Pro Wireless ($40) I've found that the best way to do headtracking is to hold the gyromouse to my forehead with a pair of ski goggles so that the "nose" of the mouse rests on the top of the glasses. I'm working on a better way to deconstruct and reassemble these two components into the ultimate poor-man's HMD. So far the straight-out-of-the-box results are very promising. Any help or suggestions for good helmets, counter-balancing strategies or experiences disassembling gyromice greatly appreciated! | ||

Hey Buckfalfa, can the "GVD300-N ($99) Non-stereoscopic LCD glasses (400x225x2)" be hooked up to a PC ? Do the have a VGA port or do you do it some other way ? | ||

Hey Water1, The GVD300-N glasses take a standard rca-style video and audio input (those yellow, red, white cables.) My 9600XT card has a composite output (two, actually!) so I plug into that. As far as a review of these glasses, they're about what you'd expect for $99. I can't read text on them, and you need to really boost the brightness to see detail (in games like Doom3.) I figure it's about a 26-degree FOV. On the plus side they came with a rechargeable battery pack and they're really lightweight. Based on Trimersion's specs, I'm betting that this setup comes pretty close to their model (minus the wireless- which is an option that could be added to the GVD300-N- and the console-controller options.) Now all I need is one of those swell "Power Ranger VR" helmets to hollow out (I hear that's what Trimersion uses for their form factor!) Cheers! | ||

If anyone has any good ideas on modding the GVD300-N to support stereoscopic display, I'm all ears! I'm figuring there has to be a way to pipe a different composite signal to each eye (since they're separate screens.) | ||

Another note on gyromouse placement- I've found that I can also get good results by mounting the gyromouse to the back of my head (my current solution is taping it to the hook part of a plastic clothes hangar and squeezing my head through the middle!) Works great as a counter-balance to the LCD glasses, too. My wife thinks I'm a loon (and rightly so.) I'm just so excited over the ability to achieve this level of immersion for so little money! | ||

Do you think a model like this (Link at bottom) that has 960*240 rez. would help with reading text or is that still too low of a rez. and not worth the extra money for this unit ? http://cgi.ebay.com/HOT-INNOVATEK-V-490-i-Glasses-Virtual-VIDEO-HMD-MONITOR_W0QQitemZ5833577633QQcategoryZ67771QQssPageNameZWDVWQQrdZ1QQcmdZViewItem | ||

I don't have much experience with different LCD glasses, so I can't be of much help there. Looks like those glasses would be 480x240x2 vs. 400x225x2 in the GVD300s (perhaps a 9-12% increase in resolution?) The glasses pictured in that link are the exact same form factor as the GVD300-N. My goal was to come in at a much lower price than the Trimersion 3001 and a fraction of the Z800s (albiet at a fraction of the performance level.) I figure the more $ you spend on the components, the closer you'll come to the price of a pair of Z800s. From what I hear, those are far better for headtracking, image and sound quality than anything I could hope to homebrew for $900. Then again, any increase in image quality over the GVD300s would greatly improve your virtual reality experience. Just be sure you weigh your price vs. performance numbers carefully. Cheers! | ||

http://www.kopin.com/BDM-230K.pdf Found this link to the optics system the Trimersion uses. No idea what the cost is, but the specs are pretty close to the GVD300 (320x240x2 vs. 400x225x2) | ||

I think if you could get your hands on an old VFX1 shell and stuff your affordable tracker and HMD in it, you'd reduce the...ahem..."[loon factor]" of your hmd Buckfalfa-- if that is your real name. ;) Check this out: http://www.geocities.com/mellott124/VFX2.htm There is another post around here where someone stuffed their z800 in a VFX1. He used canned insulation foam to create a custom fitted mount inside the VFX1 visor. | ||
| Q. Rating: N/A |
1) Can GVD300-N handle a s-video input, if not is there any type of an adapter to do this? 2) also how is the experience of using it for movies? | ||
| Buckfalfa Rating: N/A |
1) It only has input for composite video (but s-video to composite adapters are cheap and most video cards with s-video come with adapters.) 2) Movies are okay- the "screen-door" effect is minimal but still noticeable if you're looking for it. | ||

Extremly difficult to fit the screen in front of your eyes. Movies are ok. With IPOD works great!!! Oscar |
