The next frontier in human-computer interaction will be all about making you feel the virtual, digital world as though it were real and tangible. And haptics, a technology that's advanced at a snail's pace over the past 40 years, is the key to making that happen.

Not all games suffer from this malady, of course — indeed, many excel with taps and gestures. But console-style experiences in particular never feel right without physical buttons and joysticks.
