Minneapolis firm Spyeglass has put a demo on YouTube showing how consumers can interact with a large touch screen. The clips show a viewer touching an element, and dragging it to the center of the screen. It's a nifty trick, but the platform's key may be the laptop that powers the sign. Clearly the screen is programmable, which is where the real future lies. Rather than just drag [1] a screen element, viewers could tap it for more information. In a sense, a billboard [2] whose content consumers control.
