Head Mounted Displays Get Cheaper
Jason Swank writes "It looks like previous model of Sony's Glasstron was mentioned back in July, but it seems like they are now better and MUCH cheaper: 52" Virtual Viewing, 3.5 ounces, and only $499.
" The one we reported on last july costed 5 times as much, but
the cheaper model is 800x255, the $2600 version is 800x640. Still it
looks pretty sweet. I wonder if I could use these without my contacts. That would make things a lot easier.
The prices might be going down on those HMD's, but i've had my solution now for a while. My Princeton Graphics EO75 shoulder-mounted display works wonders. I drag around my portable 750 watt gasoline-powered generator, and my killer APC UPS and bear the weight of my 47 pound monitor on my shoulders. It's a wonder for my six-pack, and damn, radiation... does a body good! I don't even need a nightlight anymore. And the CO from the generator is a breath of fresh air wherever I go. Complements never cease, from the "What the fsck is wrong with you?" to the "Damn, you're messed up." Walking in public is fun for the whole family. We don't need to go shopping anymore. People throw enough fruits and vegetables at us to last all week! Get your very own Shoulder-Mounted FST monitor today!!!
I cant confirm this, because I dont know where I got the information in the first place. Your brain has a mapping from parallax distance to focal length. That is it uses the parallax distance of an object to determine how to focus on it. With head mount displays "everything" is in focus (not just things at a given depth). There were some kids early on that were using this sort of technology (as part of a study or something) and after a while they lost that mapping (to some degree I am sure), and where unable to correctly focus on objects in the real world. One solution to this is to use gaze tracking to change the focal length of the image dynamicly, but I dont know if that would even work. I imagine you would need to have a sytem that can track the users gaze and change the focal length faster than a human can change the shape of the lense in thier eye. Unfortunately there are other such mappings that we dont have an understanding of and well have to find them out as well.
As a continuation, I had always thought that a solution could be doing depth of field in software and displaying the resultant image. You still need the gaze tracking hardware to figure out what the user is looking at and thus what depth should be in focus, but you wouldn't need the extra optical hardware, but now that I think about it this is of no use at all (well it would probably look pretty). The problem is that the blured image would still be completely in focus everyware. And once again, since your mind no longer has to keep track of focal lengths... disaster.
