HMPD - has anyone built one of these?

If the plastic reflective surface is curved to create a slight magnifying mirror effect, then your eye will be able to focus on the image as though it were further away. As long as the plastic is relatively thin it won't affect focus onto distant objects.

Now, getting a proper curved shape is another issue. Perhaps a magnifying mirror can have its reflective surface removed, leaving you with a curved glass. But, I have doubts the curve is the exact curve necessary. But, it may be good enough.

The Airscouter is monochrome, low FOV, and does not use any real novel design. We have a few threads about it if you search, but basically, it uses a scanning image projection element that is very similar to the Private Eye P4, or the Virtual Boy.

this makes an interesting reading, may give people some ideas..

That is the patent that the Headplay uses. It is interesting, but not really suitable for the kind of stuff we are making.

can you give me some more info palmer ,ive been looking around for a diy hmd and still not sure what the best way round to go debating on single display similar to what you have done , or twin displays mirror no mirror ,fresnels leep optics ,its all abit confusing which way to go, also its ni on impossible to get leep optics anywhere no one seems to sell anything similar very frustrating..

ps have also been looking at pico laser projectors because they never go out of focus so you can have a curved suface then maybe put right with warpilizer software thew my brain hurts
