Cameras as input devices: "As I’ve written in the past, one of the wonderful aspects of mobile devices is the availability of alternate input devices such as voice and camera. A recent article on camera phone search technology describes several companies using the camera as web input."

Of course, all the noise recently has been around barcodes (in their 2D and 3D variety), but that's not all that can be done here. We're putting out a proposal in this area at the moment with some lovely ideas in it - you know, the kind that when you hear them you break into a grin because they're so very sweet.

I'll write about it soon.
