Hello everyone, and let me start by saying that this site is a plethora of informative data! There is great sense of community in here, and without all the help and support of some its members this work would have been a lot more difficult. Many thanks to Foisy, 3dpmaster, LostBrain and Geekmaster among the many for been very helpful with many of their threads.
VR was an aspect of my interest during the late 80's and 90's era. Clearly the technology was not ready for prime time at that time. The Rift is a definite breakthrough in that it brought VR back into the public consciousness. So let us see how it all pans out in the near future.

I have made some single display prototypes, one been a 7 inch and the second 9.6 Ipad 3 display.
The Ipad 3 version was interesting because the visual fidelity was great. However, the draw back (at least for me) was the size and then trying to fit the right optics for it. At the end it all came down to the size which didn't make it practical for me. The 7 Inch was OK, but the resolution clearly isn't as nice as the Ipad variant.
Foisy's InfiniteEye v.1 was a great concept to use as reference since it can split the image on different LCD's. Lost Brains approach is interesting but beyond my tinkering abilities!

So my Portal Dual Hmd derives some aspects closer to the Infinite Eye v.1. I will like to test some optic ideas that derives from Geekmaster suggestion on different threads with some of my own implementations. I wouldn't say there is anything new here, it may be more of an amalgamation.
So the first unit will be a dual 7 inch 1280 x 800 since the components are low price due to the phone market. However, with the Nexus 7 2 @ 1920 x 1200 around the corner, this will likely be the final LCD's on this unit, after the replacement parts are available.
The second unit will probably incorporate a design change from the first including better ergonomics, hopefully. I will update on that after the first prototype is in good working order.
I will include some pictures here of the first prototype.
I will update as I put it together later this week.

Tracker:
Currently I'm testing the Yei 3Space sensor but it isn't working to my linking...at the moment ( Baggyg and Foisy have been of great help with that). More playing around with the calibration, definitely needs it. I do not think I would want to have a large FOV image recklessly jittering all over my face in which can only lead to one thing, and that can not be of any good

Edit: I am including Jake Portal Kid character I drew for fun!

PS. Here is a Youtube video of some early test of the version 2 of Portal Dual

Update:
I have finally taken the time to upload the software and hardware files for the Portal Dual. The software was intended to fit the needs of Ultra Wide FOV HMD's. The Portal engine is an incomplete demo where you can import files and walk around a simple environment. It has the data to synchronize dual display with no noticeable performance issue.
The software is functional but it is not where it should be. The best case scenario is to perfect the visor side of the engine and make into a driver that can be then incorporated to other SDK's such Unity and UDK or any other SDK for that matter.
If not anyone can just take the current form of the engine and continue make it more robust, flexible and easy to use.
I cannot further development but I hope this can be useful to others that have the passion and ambition to help build from it.
The software can be adjusted to work on dual display or single ones, but imputing the proper resolution. I have a dedicated page where you can find the download files.
For the software side there are two things.
1. The Portal Engine= is the engine.
2. The Portal Visualizer= this is the source code.

If anybody wants, they can upload it in “Github” for everyone to keep track of the evolution of it.
Please let me know if anyone has any questions.
One thing to keep in mind is that I am not a software engineer, so I will answer the best to my knowledge
Cheers All!
