Engadget - What's that, you're not into changing the channel with that boring old remote, or even with your voice? Murata's ground-up Tactile Controller brings a real twist to every couch potato's favorite gadget. Quite literally. The company's prototype remote uses touch-pressure pads and pyroelectricity to analyze the position of a piezoelectric film. In English: a plastic film produces tiny amounts of electricity at various voltages (output as data) when it's forced into a variety of positions, letting you change the channel simply by twisting the controller in either direction, or flexing to adjust volume.
