I noticed the i-o Display Systems is advertising both the i-glasses SVGA and the i-visor (Cy-Visor). Both claim to be 1.44m pixels that will display 800x600 images. Yet they don't explain when one would choose the i-glasses SVGA over the i-visor and vice versa. From the little information I have received, I would think the I-Visor/Cy-Visor would be the better deal because it allows many more input sources whereas the i-glasses SVGA only allows PC source input. The i-visor also claims a 31 degree FOV to the i-glasses 26. So what does the i-glasses SVGA do that the I-Visor/Cy-Visor does not? I must say that when it comes to the world of HMD's the information available is few and far between. Even this site does not have adequate answers. The reviews section is pathetic. I think there are a total of 2 reviews for HMD's, the last being over a year old. What makes it so hard is that it's impossible to try before you buy. I have no idea where I would go to see a working demonstration, yet there is no source for solid unbiased reviews. |

I am confident that either myself or others who post on these boards probably could do a better job making this site more informative and updated. I too would like more information about the comparisons between the I-Visor/Cy-Visor and the I-Glasses SVGA. Unfortunately, this site seems to be targeted mostly at 3-D technologies; not at hmds in general. Don't misunderstand what I am saying; I like 3-D, however, I would appreciate some more information concerning hmds, even if they're not 3-D. |

The information and reviews in this news group is only as good as the information it receives. If manufacturers do not give detailed descriptions of their products then it is very time consuming and almost impossible to keep up to date. However with regards to the difference between the Cy-visor and i-glasses SVGA, this is simply a question of design. The Cy-visor has a flip-up display and supports all video formats including PC and the i-glasses SVGA is based on a new design of the other i-glasses models and only accepts PC signals, however a smart cable is available as option for composite and S-video formats. Both products use the new display technology LCoS and possibly the same display panels. The I-glasses have a slightly smaller field of view which I believe is due to the fact they have no IPD adjustment, they have also increased the frame update rate to 120Hz compared to 75Hz on the Cy-visor. Which unit you should choose is entirely up to your personal preference, they are both very good HMD's and there is currently no other HMD that offers the image quality that they do in that price category (correct me if I'm wrong). Via the following links you can see the pdf specifications for both units: 1. i-glasses SVGA 2. Cy-visor DH-4400VP If you have any further questions I would be more than happy to try and answer them for you. Regards, Cybermind Nederland |

w.r.t. different frame rates : the SVGA panels from microdisplay.com are rated for 60-270Hz frame rate. Since you need three images (RGB) per frame, this will give a maximum color frame rate of 90Hz. The 120 vs. 75 Hz frame rate IMHO is just the maximum accepted input rate, which is more related to the input ADC quality. |

Well then, I am satisfied with the information that I have received, however, I must make one correction. The Cy-Visor has a much poorer image quality than Olympus' Eye-Trek FMD-700. I know this because I once owned the Cy-Visor and now own an Eye-Trek. The only disadvantage the Eye-Trek has is that it currently has no stereoscopic 3D capabilities (with the possible exception of TekGear's Eye-Trek ripoff). |

We've tested the Cy-visor 3D and are very impressed with it's performance and have received the same feedback from our customers, it offers 3 modes of stereoscopy for PC and video and cost less than US$ 2000.- You can see the specifications via the following link: Cy-visor 3D We haven't tested the i-glasses SVGA 3D yet, but hopefully we will do so today. The i-glasses SVGA 3D is about US$ 200.- cheaper than the Cy-visor but doesn't support dual input and for video input an optional smart cable is required. We are glad to hear that Krosse feels that the Olympus Eye-Trek FMD-700 is better than the Cy-visor and would like to say that we respect everybodys personal views, we always try to give an unbias opinion based on our personal experience however our experience say's otherwise so I think it all depends on your personal preference. We would like to wish everybody visiting this discussion group a Merry Xmas and a Properous New Year. Cybermind Interactive Nederland |

One thing about the i-glasses SVGA over the Cy-Visor is that it appears that the i-glasses is more immersive. The Cy-Visor looks like a very open design while the i-glasses looks like a pair of goggles that completely block outside light. Does the Cy-Visor have some kind of shield that can be attached to make the viewing more immersive? |

CybermindNL, Can you tell me how I would set up a video to be shown in page flipping mode with the Cy-Visor? Would the video in above below format do the trick? How fast of a pc or laptop must you have? Will you ship to the U.S. and what is the exact price? Thanks, Steven |

Neil: Both the Cy-visor and i-glasses SVGA are not immersive, however the Cy-visor has interchangeable eye-caps which when placed on the Cy-visor gives a immersive effect, these cannot however be used with prescribed glasses Steve: Page flipping modes requires a odd and even field to be sent to both LCD's, the control box rearranges the images to give you stereoscopy, for more information see the PDF file on the Cy-visor 3D in my previous message. For above, below format you will need Sync-double mode which is not supported by the Cy-visor 3D. The Cy-visor 3D is US$ 1995.00 and we do ship to the US. Anonymous: We are not aware of the life span of the LCD's in the Cy-visor, we will have to contact the manufacturer to answer this question, the Cy-visor has a standard one year warranty and at this moment they are repairable. It is not possible to wear 2D headsets and produce 3D images with a Anaglyph glasses, this would require a single CRT Lens and the i-glasses and Cy-visor both have two LCD's. Merry X-mas to all, Cybermind NL |

Cybermind NL, Would you tell me the differences between the hi-Res900-3D, Cy-Visor SVGA 3D, and the I-glasses SVGA 3D in terms of obtaining high resolution for 3D Video - and ofcourse price? I see you can send a seperate signal to each eye of the hi-Res900-3D. My goal is to use two video cameras to record 3d Video and view the synced full resolution pictures for each eye. I don't know how that would be accomplished. I thought that Page Flipping or Sync Doubling would allow that but your answer to my earlier question stated: "Page flipping modes requires a odd and even field to be sent to both LCD's, the control box rearranges the images to give you stereoscopy" I assume the unit then blanks out the correct corresponding fields for each eye. I don't see the difference in this than from using interlaced 3d since the info for each eye would only be half the fields of the screen. Wouldn't Page Flipping still yield a half resolution screen for each eye compared to a 2d Video image? And you stated that Sync Doubling is not an option for the Cy-Visor. I would like to obtain full resolution for each eye for hyper clarity, color and brightness. Is this possible with any of these three units? Thanks, Steven |

Steven, our hi-Res900™ 3D is a ruggedised version of the Cy-visor 3D, it is the ideal solution for our customers that require a multi-user HMD and full immersion, the optics are exactly the same as the Cy-visor 3D as is the stereoscopic modes that are supported. All three models, the Cy-visor 3D, i-glasses SVGA 3D and hi-Res900 3D offer excellent image quality. The i-glasses SVGA 3D is the cheapest model at 1995.00 Euro followed by the Cy-visor 3D at 2225.00 Euro and then our hi-Res900 3D at 3995.00 Euro. What I mentioned in my previous reply was based on the assumption that you were sending a single sync-double signal to the headset and not two separate video signals. However it is possible to send two separate signal to the left and right eye with the Cy-visor 3D and the hi-Res900 3D. You will also achieve your goal of full clarity for both eyes. In our previous message dated the 21st December there is a link to the pdf data sheet on the Cy-visor 3D, which also explains the different 3D modes and how they work. I hope this clarifies your query and apologies for the misunderstanding with regards to your first message. Regards, Cybermind NL |

Cybermind NL, Thanks for the response. I am still unclear, however, as to how I would deliver full screen left and right eye perspectives to the two separate feeds on the Cy-viser 3d. Would you mind discussing how this would be done? The 3d Format and whether you would use a special graphics card, etc. Thanks, Steven |

Steven: You can send left and right eye image to 2 difernet VGA output on dual optput nVida graphic card by the help of Quadro drivers. It work only with OpenGl aplication suporting native OpenGl stereo (Quake 2,3, profesional software). It is probably possible to code D3D wrpaers with similar future (VRCaddy with proper configured Winx3D could theoreticaly do that). .. |

Michel, Thanks for answering. I need to send the separate signals for 3D Video - is that possible to do with a dual head graphics card or by some other means? Separating above/below for instance. I want full screen resolution for each eye, synced of course. Thanks, Steven |

Steven: Yes. By the help of OpenGl based stereo-video player witch I have developed in recent time (in alpha testing stage now). You will need an dual output nVida graphic card, hack it to quadro, use RivaTuner to force left and right surface output to different conectors. I did not tested that setup, but somebody on this WWW did (maybe Alex ?). Let me know when you have such setup (tested with some stereoscopic OpenGl application). I can send you the code for aplha testing ... |

Yes, I had Quake3 arena running with on an ASUS v7100 2V1D (GeForce2MX) graphics card. I used RivaTuner's quadro hack. It was under Win2000. It ran smoothly on two monitors. I never got to testing it with two projectors for lack of a proper non-depolarizing screen. And I never got it to run (not properly, that is), with other applications and drivers (tried WinX3D and VRCaddy among others). Running above-below or side-by side-video is no problem on this setup. Just extend the player to both monitors or projectors (note that this might only work with certain OS'es - it think I used Win2000). But Michal, what's this issue with an OpenGL video player? What's the use of OpenGL with video? Isn't it primarily for 3D-animations in games, CAD/CAM, 3D Studio Max etc? Please enlighten me! Alex |

Alex: I use the OpenGl in this player for following tasks: 1) Standardized HW page flipped output in window or full screen. No other API gives you standard for in window HW page flipped stereoscopic output now. 2) For HW accelerated zooming of the video images and image mainpuations at all. OpenGl have commands for both 2D and 3D data manipulation, it is de-facto DirectDraw and D3D in one, it can cover all graphic task including e.g. HW accelerated 2D video effects for video editing software. To develop other standard by Microsoft (D3D, Direct Draw ...) was probably one of the bigest stupidity in the computer history, but this is another story ... Steven: The Alex described method is much more easy and faster than the one suggested by me. You do not need any special player for such experiments ... |

Another queston regarding i-glasses vs cy-visor: I have never tried either one, so I was wondering what would be the visual difference between a 76" screen at 13' (i-glasses) vs a 44" screen at 6.5' (Cy-Visor). From what I gather this would be the difference between a larger screen that appears farther away and one that is smaller but closer to the viewer. But that doesn't tell me what looks better. Anyone with experience with both (Cybermind nl)? |

Neil: Lets say that the i-glasses image size is 38" at 6.5'and the Cy-visor 44" at 6.5'then you can see that the Cy-visor offers a slightly larger virtual image. You should also take into account the diagonal field of view, Cy-visor 31.5° & i-glasses 26°. The image size of the i-glasses is smaller than the Cy-visor but the image quality is equally good. We believe that the i-glasses has compensated the image size and the field of view by doing away with the IPD adjustment found on the Cy-visor. Annonymous: We have the i-glasses SVGA 3D and the Cy-visor 3D both in stock and unless I-O have come out with a new version it is not possible to feed two separate signals into the i-glasses and as far as we know it only supports frame sequential. The Cy-visor 3D however, which is now called the 3D i-visor accepts two separate inputs for video and PC signals, so maybe you confused the i-visor with the i-glasses. Cybermind NL |

CyberMind NL, Please describe the interlaced mode of the CyVisor 3D (as referenced in http://www.cybermind.nl/Info/CyVisor3D.PDF bottom of p2). Are the Blue and Yellow images 800x600 each (ie video card outputting 800x1200)?? Or is the entire interlaced image 800x600?? If it is the first (800x1200), what frame rate can they handle? I would ultimately like the 800x1200 at 75Hz or better. Thanks. |

MH and Alex.. can you elaborate on the use of the GeForce2MX? Why does it need to be hacked to the Quadro2MXR? What exactly does your code do? Does it render the two views independently and send them to the separate frame buffers for the two RAMDACs on the MX? Where does this software sit? Between the application and the OpenGL driver? Which applications did you have running, and what sort of frame rates could you get? I am interested in running this for the twin input capability on the Cy Visor 3D. I understand that Quake 2 and Quake 3 have some inbuilt support for stereoscopy.. anyone got any info on this? |

- Do the i-glasses-3D and Cy-Visor-3D retain true full 800x600 resolution per eye in page-flipping mode? - Are the stereo-reverse buttons easy to reach? Do the HMD's look for Revelator/nVidia trigger signal or any color-line-codes to set stereo-orientation automatically? - What is the maximum input frequency in page-flipping mode? (According to the specs the max. vertical input frequ. is 75Hz, but this is too slow for most page-flipping-drivers.) - What is the maximum frame rate per eye in page-flipping mode? - What is the maximum input resolution which works for line-sequential (interlace) mode on the Cy-Visor (Miles already asked this) - Does the Cy-Visor have dual-composite-video input or dual-Y/C-video-input or both? - Will any of the HMD's presented at CeBIT this March? Thank you Christoph |

Anon. we haven't got any actual reports over the lifespan of the i-glasses or the I-visor but our tests have proven that they are capable of running for a long duration without any problems, the I-visor does however have a built-in power save mode that turns of after two hours of use (this function can be removed). Miles, the entire interlaced image is 800x600 and not 800x1200, the image is split into odd and even lines so that only the even lines (50% of the image) are set to the left eye and the odd lines to the right eye. Christoph, the i-glasses SVGA 3D and Cy(I)-visor 3D both retain there full colour mode when viewing page flipping mode. Both the i-glasses SVGA 3D and Cy-visor 3D have a stereo reverse button, The i-glasses SVGA 3D looks for the revelator/nVidia trigger signal to set the stereo orientation automatically, the Cy-visor 3D must be set manually to page flipping mode or any other mode. The maximum input frequency for the Cy-visor 3D is 75Hz which is not too low for page flipping mode, our test show that we have a flikker free image with the Cy-visor 3D at 75Hz and if necessary we can also adjust the left and right eye independantly to avoid flikker via the control box. The i-glasses SVGA however has a maximum input frequency of 100Hz and does not have the option to adjust screen flikker. We can honestly say that there is not a noticeable difference in the image quality produced by the Cy-visor and I-glasses in page flipping mode, we can only assume that the control box of the Cy-visor 3D rearranges the image in such a way to avoid screen flikkering produced by shutter-glasses at the same frequency. The Cy-visor 3D accepts dual composite video and dual VGA input. As far as we are aware the HMD's will not be presented at the CeBIT in March but will be at the Siggraph. Hope this helps.

Thank you for the info. My question regarding input frequency wasn't about flicker, but about compatibility. The ASUS page-flipping driver for example, which is my favorite for certain reasons, works only at 100Hz upwards. Another issue is frame rate. 75Hz provides up to 37 frames per eye. High end hardware can do more for action games. Christoph |

Hmm... I missed reading this post earlier. Very informative & interesting reading here comparing the I-Glasses SVGA 3D and the Cy(I-visor 3D. Would Cybermind NL have any more comments about these two units? Any faults/returns in the last few months? Based on the information I have read so far, I am still leaning twowards purchasing the Cy-Visor 3D. The larger FOV, multiple inputs and Sony InfoLithium Battery support (up to 6hrs?) are all advantages over the I-Glasses SVGA 3D unit. My 2 remaining concerns for now are: - Flicker? Under what circumstances might one experience flicker on the Cy-Visor? Surely seperate dual VGA or video inputs would allow the unit to do 75Hz for *each* eye's display? - IPD adjustment? I recall using the VFX1 many years ago and it's IPD adjustment seemed to be a once off thing yes... get it right once and leave it? |

Hi could you briefly (if possible!!) explain what graffics cards/ motherboards/ chipsets/ drivers are necessary for achieving 3d stereoscopic using either of the 2 aforementioned glasses. Also, are there any cheaper 3d stereoscopic video glasses available? Can you achieve anything as good with cheaper non 3d glasses and a 2d -3d conversion box? cheers! |
