It’s called the ButtKicker. The device attaches to your couch. When the screen shows an impact—say, two hockey players slamming into each other—the ButtKicker shakes. It lets you feel the action while you watch it.
It’s now set up at the SAP Center in San Jose, California—the ice hockey arena that is the home of the San Jose Sharks. The side panels of the rink have 76 built-in sensors. When a player hits that wall, people can feel the impact through their ButtKickers.
