SEOS 120/40 Ultra Wide Field-of-View

Posted March 3, 2014 by David in VR History

Virtual Reality has come a long way the past couple of years thanks to the extremely competitive phone and tablet markets developing high resolutions screens and positional tracking systems and making them affordable to the general public.

Its not hard to forget that just a few years ago top of the range HMD’s would cost tens of thousands of dollars and only be used in commercial or government programs with large budgets.

Here at Virtual Reality Reviewer we plan to take a look at some history’s more unusual VR experiences and shine a light on the forgotten developers who trail blazed a path to where we are today.

For our first trip down memory lane we are going all the way back to 1999 when the SEOS 120/40 HMD was released on the world. This HMD from what we can find online was mostly used for driving or flight sims as it was extremely bulky and it weighted 2.2lb. It used two LCD displays and had a resolution of 1280 x 1024 per eye which was HD at the time.

Also in the 90s you would have needed a top of the range PC running two powerful GPU’s as there were two 1280 x 1024 video inputs on the SEOS one for each eye.

Not much else is listed about this HMD on the net but we did find the original maker’s website here and this is also a trip back to the 90’s as its an archived site that time has forgotten.

I have never seen this HMD in the wild and I suspect that this could be quite a rare piece as the original price tag would mean that very few people in the private market could afford one and as companies find equipment obsolete they either store it and forget about it or dump it completely.

If you have ever got the chance to use a SEOS HMD please let us know your thoughts below we would love to hear them.
