This enchanting gadget will learn from your existing remotes and is compatible with most common devices. After some practice, you'll be a TV controlling wizard. The wand uses accelerometer technology to recognize specific gestures for which command to transmit. Yes clearly it is a novelty item. Form tramples function with just 13 commands for $80 from ThinkGeek.com. You can view some gesture control animations at TheWandCompany.com
As their documentation states, "You look like an idiot waving a wand in front of a TV. Unless it suddenly works."
