[Larry] put a different spin on a television remote control. He used an Arduino and an IR receiver to learn the codes from the factory remote. Now that he can use an IR LED to playback these signals he worked on an alternative to pressing buttons as the input. The ultrasonic range finder seen above allows him to wave his hand in front of the device to change channels and alter the volume levels. Check it out after the break.

There are many other ways that gestures could be used with this system, including a laser based input method. We’d like to see [Larry's] system incorporated into a coffee table of some kind, as long as there was an opening for the range finder to work.
