Searched the forums, hawked google for a bit; Couldn't find any reasonable methods for using something like the following...

http://www.icuiti.com/iwear/products_vr920.html

Anyone have any ideas? The idea here is to use a head-mounted display or equivalent device with an N800 and the like.
Just starting programming and whatnot, so I don't know much about this stuff, but I figured perhaps there was a way to transmit video via USB (The host-mode project I noticed is progressing nicely).

Halp?

I think that any device plugged into USB host on the N800 will be limited to 12Mb/s which will get you a 640x480x16bit image at 2.5 frames per second at best.

If you get a different Linux handheld with a compactflash slot you could get a compactflash vga card but those are pretty much just as bad off in the "lacking bandwidth" department: http://tuxmobil.org/cf_vga.html

Seems like someone has the idea of mangling the signal coming out of the LCD controller back into a VGA signal on his gumstix: http://ask.metafilter.com/43115/Conv...-of-LCD-to-VGA

The Dell X51V seems to have a VGA-out "presentation" module. I haven't heard anything about Linux support for the vga-out (though I haven't looked that hard). I suspect that we're not talking about 640x480x16bitx30fps in this case either, though.

Unfortunately it looks like the only real solution is a UMPC or an MID (when they start coming out later this year).

If you find something keep us posted.

What would you use it for other then watching movies?

How would you know where on the screen you were touching?

It's for my sophomore science fair; I'm doing a presentation on the uses for ubiquitous computing. The design I'm using has a gutted webcam mounted on the rim of a baseball-cap, which hangs just in front of the display.
The display is not wholly immersive, and I am planning on writing software that would allow use of the touchscreen as a touchpad(ala` http://www.mulliner.org/bluetooth/xkbdbthid.php).

Thank you for your reply, Johnx.

Has a look at this site; it was just posted on another site I visit:

It a Sony UMPC + HUD:
http://www.cs.vassar.edu/~priestdo/latest.html

or wait for the new SHINY oled HUD:


"A new Linux-based portable media player (PMP) features an eyeglass-like head-mounted display with 800 x 600 resolution. Dreamax's Indicube i-800 PMP provides an experience similar to sitting two meters away from a 54-inch screen, the vendor claims. It uses an 0.44-inch eMagin OLED display, claimed to offer the smallest pixel pitch in the industry."

Edit: Site is /.ed at the moment......
