I/O gadgets

Here are some input/output gadgets that look pretty cool:

• A pen-shaped document scanner: DocuPen. I wonder if software could put the page back together, removing the distortions.


• A pen input device for cellphones from Nokia. I wonder why more smartphones don't allow sending ink messages yet, since it seems more convenient than digipad typing.


• One more head mounted display. Although I really look forward to having one of these and nearly bought a SV-6 from MicroOptical, the social pressure of looking seriously weird is still too strong ;-)


• Production-ready e-paper from Philips (see the video). It feels like e-paper has been "nearly done" for longer than Duke Nukem Forever now and I'm still waiting for an actual consumer device from E-Ink.


• Wearable keyboards like SenseBoard or LightGlove (via I4U). I also own a HalfKeyboard and just ordered a Virtual Keyboard.

Update: There is also the matchbox sized projector ;-)
I also forgot digital pens like Logitech's io pen, but it's still too bulky and could use some support for converting to Tablet PC's ink.
Another wearable display: Second Sight.

Update: I just saw the sixth episode of "24" (third season) and noticed that Chase wears a MicroOptical wearable display. Cool ;-)
