Those clever folks at the MIT Media Lab have done it again. This I/O brush looks like what I think of as the kind of brush men used to use for shaving, but it picks up color, texture, and movement of any brushed surface. Sound amazing? It is. According to the Media Lab I/O brush web site, they're looking into a consumer version.
What do you think a system like this would cost? I'm thinking it wouldn't actually be that expensive. Existing monitors could be adapted for touch screen. There's a camera, a couple of LEDs, and two touch sensors. None of that's particularly expensive, I don't think.
I'll be in line for this, that's for sure :)
