Game controllers have always been imperfect. They let you do stuff in a game using a combination of buttons and joysticks, but you rarely feel like you're actually in the game.
Well, now a new controller called the Knuckles Cap Sense will allow a computer to recognize your fingers. This means game developers can tell the difference between you pointing and holding a fist, or how many fingers you're holding up, and perhaps even if you're showing one finger in particular.
"This. Is. Magic," said one commenter on Steam's development site.
While it's not exactly magic, it's rather cool. Other companies like Facebook's Oculus, whether it be pulling the trigger on a virtual gun or pointing at a virtual menu. But full-hand controllers have been largely elusive.
Valve, which partnered with HTC to design, had initially shown off the Knuckles controller late last year to some developers, and now it's publishing documentation for developers.
Valve said it's begun sending initial units to developers for feedback and plans to make further announcements sometime soon.
