I tried what you said. I can get a clear image in my eye through the reflection a CD cover in dark room. But the problem is that image of my cellphone is not projected from infinity distance which meas my eye can only focus on cellpone image or outside object, not simultaneously. I can not get a focused ,mixed image and clear image.

any idea of this?

I hadn't really thought about that as i intended to make a closed system anyway. I dont see how that could be done? At the end of the day it is the lens on the eye that focuses a set distance for the retina so i cant see how it could be done?

Oh, i also used a mirror and had the cd facing away in my test as per my pictures before, that make the screen the correct orientation.

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.

it seems the Japanese has just found the way. Their new product airscouter is just what i want. but it's extremely expensive.

anyone has any idea how the projector of airscouter works?

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
