5DT – Virtual Reality for the Real World! Page 1 of 3 Siggraph 2004, Los Angeles, California, USA Release Date: August 10, 2004 5DT Releases New Head Mounted Display (HMD) Series 5DT , a world pioneer in Virtual Reality (VR) peripherals and training systems, today released a new advanced Head Mounted Display (HMD) Series. The series includes: - 5DT HMD 800-26 800x600 Resolution, Liquid Crystal on Silicon (LCOS) technology, 26° Field of view (FOV) HMD - 5DT HMD 800-40 800x600 Resolution, Organic Light Emitting Diode (OLED) technology, 40° FOV HMD - 5DT Virtual Binoculars 800-26 800x600 Resolution, LCOS, 26° FOV Generic Virtual Binoculars - 5DT Virtual Binoculars 800-45 Effective 600 Circular Resolution, OLED, 45° FOV Custom Virtual Binoculars - 5DT Virtual Laser Range Finder 800-45 Effective 600 Circular Resolution, OLED, 45° FOV Custom Virtual Laser Range Finder (V-LRF) - 5DT Virtual Night Vision Goggles 800-45 Effective 600 Circular Resolution, OLED, 45° FOV Custom Virtual Night Vision Goggles (V-NVG) - 5DT Virtual Monocular Display 800-45 Effective 600 Circular Resolution, OLED, 45° FOV Virtual Monocular Display .... The 5DT HMD 800-26 offers 800x600 Resolution (Liquid Crystal on Silicon [LCOS] technology) and a 26° FOV. This is 5DT’s economic HMD model. ..... The 5DT HMD 800-40 offers 800x600 Resolution (Organic Light Emitting Diode [OLED] technology) and a 40° FOV. The unit also has a 3m long cable. This is 5DT’s high end HMD. Both units offer superior sound quality packaged in a sleek, comfortable and extremely light headmount design. ..... ‘Our latest HMD Series addresses most of the problems that were experienced by simulator users and system integrators to date. They need a wide field of view and a crisp image packaged in a comfortable lightweight headmount with an interface cable that is long enough to not restrict movement. We have now reached a performance level where the focus will move away from the HMD to the realism and functionality of the application software.’ Said Mario Schehle, Virtual Reality Hardware Division Manager of the 5DT Group. http://www.5dt.com/downloads/MediaReleaseSiggraph2004HMD.pdf | ||

$4950 USD for the stereo unit! ouch, I don't think I'll be buying one any time soon. http://www.5dt.com/products/phmd.html Ben | ||

4950 for 40 FOV and stereo..... maybe | ||

Truely, what the heck is so difficult to make the FOV 90 degrees? Resolution? I just don't understand why companies are spending so much money on near-to-the-eye tech and not be able to create a large FOV HMD. | ||

Optics will be prohibitively expensive. | ||

Please do tell how this one achieve such a wide FOV. http://www.est-kl.com/aufbau_general/index_hard_hmd.html?http://www.est-kl.com/hardware/hmd/seos/seos_12040.html | ||

BOPrey, No one said it could not be done. They said it was expensive. What do you think that HMD cost that your referring to?!?! | ||

If you don't want to stress your imagination - that one is 66000 EUR... | ||

It's only 66000 Euros, i think i'm going to buy two of them ;-) | ||

BTW I think that was $4950 for the 28 degree stereo model. | ||

Anonymous, Yes, I know. My questions were, what are these optics made off? What kind of glass cost 60K Euros? | ||
| BOPrey Rating: N/A |
Also, I would want to find out how they achieve that FOV, number of lens and F-length, etc. | ||

The optics would be very difficult. There would be a large number of components making the system heavier. Also, you need to have the pixels to fill the field. Most of these displays are running around 2 minutes of arc per pixel. For example, if you have 800 pixels in 28 degrees, that comes out to 2.1 minutes for each pixel. If you put the same display into 90 degrees, each pixel would be 6.75 minutes and the image would not look sharp. If you want higher resolution then you either need a high resolution micro display (very expensive) or you need to decrease the stereo overlap between the eyes. That is, you can have a 90 degree fov with only a 40 degree stereo overlap. There are compromises in all of these system designs. | ||

Optics for high field of view HMDs are expensive for several reasons. These HMDs use several aspheric glass optical elements which are very expensive. The SEOS hmd is using a rear projection screen as well in there (expensive for high-resolution screen material) The eyepieces are adjustable focus. Low volume makes everything much more expensive as well. These are complex lens assemblies, not just a simple magnifier. Also, the high-resolution microdisplays are expensive in low quantities (which as Anonymous said are necessary for higher FOV displays) | ||

Thanks for clearifying the aspheric optic part of the equation. I had the sense that, in order to achieve WFOV, the image has to be projected directly onto the retinea, and yes, these lens are expensive in low volumne. It is interesting to know that SEOS uses a rear projection screen as well. | ||

This simple design give a very very wide FOV. http://www.cse.wustl.edu/~pless/omnivisFinal/nagahara.pdf | ||

Let us know how much it cost you to build one and maybe we'll follow your example. | ||

I will ask someone to make the mirrors for me. For the displays, I am going disassamble my i-glasses. |
