Hi:

   I am considering buy a HMD for AR. Now I found
there are total four equivalent product on market:

1 cyberEye CE-500

2 Cy-Visor 

3 i-glass SVGA

4 Eye-Trek FMD 700

5 Tekgear 

   All of them have high resolution. But there are
still some  difference on price and performance. Since
I never bought HMD. So I wish someone can give me some
advice about that . 


best wishes

calvin

Hello Calvin,

You actually can do AR with an opaque display but
it will be video see-through AR by using a camera
to capture the real world.

I have not tried most of the display you mention but
I do know that the previous version of the i-glasses
was only 640x480 which is poor. Moreover, the
pixels are "time interlaced" (I dont think I have the
good term here), which basically means that when
you move your head, you will see the RGB 
components separated for each pixels instead of
seing one composite color per pixel. You may want
to pay attention to that.

Yohan

Hi Calvin

>  there are total four equivalent product on market:

I've noticed that you've posted this couple of times so I'll do my best
to give you some kind of a reply on some of the products I know - I 
hope I'm up to date and haven't got things wrong but there appear to be
a few fundamental problems with some of the choices that you've listed 
(perhaps that why other folk have not responded).

>  2 Cy-Visor 

You couldn't do AR with this if you wanted to, there's no see through 
mode.
  
>  3 i-glass SVGA
 
despite your assertion I think that these are fairly low res - but then
again they're low cost

  
>  4 Eye-Trek FMD 700

Once again you couldn't do AR with this if you wanted to, there's no 
see through mode.

all the best,

Mark

hi,Mark  :

First thanks for your advice about HMD. But I really
do not think I can choose one kind since almost you
deny eevry kind  of HMD I had metioned. since I will
almost do the video-see through AR system. maybe I can
minimize the range. How do you think about it ?


best wishes



calvin

Forgive me if I've not read your mail properly. As far as I know if 
you're going to do AR in see through mode you are limited to either 
getting hold of a second hand (or end of range) glasstron or the 
I-glasses at the 'low' cost end. But this may not be a bad thing, there 
are of course all sorts of issues to do with HMD's, I've done immersive 
work with  a virtual research V6 which by many standards has a low 
resolution image, but for the stuff I want to do its good because of 
its field of view, it all depends on your priorities and in the end its
all down to content rather than kit.

If you've alot of money take a look at Kaiser's range 
<http://www.keo.com/>.

all the best,

Mark
