Hello guys !
With all the stuff around about Palmer's awesome HMD and John Carmack promoting VR, I gathered my motivation back to finish this project

Since the RIFT works on the same concept, I know there will be some video games for it (Doom 3 BFG and any game with Cybereality/Emerson custom drivers).
Here are its specifications :
resolution : 640x768 per eye
HFOV : ~130° (I'm not sure of it but it is greater than binocular vision which is 120°)
VFOV : full
weight : 800gr without the straps; 1kg with them (It's pretty heavy I know, but the system I built to tie the HMD to the head is quite comfy)
input : HDMI (although the controller board can take VGA and component video, I just didn't need them so I didn't make holes for it in the plastic case)
the screen is still the same : Sharp 7.2" LQ072K1LA03 1280x768
and the optics are the same as in the OP (I tried different lenses but finally the aspheric ones are the best I found for this screen)
I did not mount the lenses on an IPD or focal adjustable system (It was too complicated to design in a DIY way for me :p) but it's not a problem, the exit pupil is huge so there is no need for IPD adjustability and the focus is set to infinity.
The binocular vision covers the central part of the screen and leaves the egdes of the screen for peripheral vision. Unlike the RIFT, the centers of the stereo images need to be shifted toward the center of the screen.
Here is a picture with the centers of the images in front of each lens

And here the same picture, zoomed and shifted in order to keep the centers at the same location but using the all panel

Could you (Cybereality and/or Emerson) take that into account if you make parameters for your video drivers?
For my tests I used 3D videos and the excellent player Bino3D which allow me to set the parallax (I set it to -1 (the minimum)) but it is not possible to zoom the image so I loose the pixels on the edges (and so I loose a little HFOV).
Maybe I should try to modify it (its source code is available).

but what I'm interested in, is games (with headtracking)
I never tried an HMD before this one (I ordered a ST1080 but I'm still waiting for the french customs to stop retaining it)
I'll wait to see what's happening with the Oculus RIFT and I'll buy the same headtracker (Hillcrest ?)
Enough talk, here are some photos and videos
