Nintendo PowerGlove (1990)

For all intents and purposes, the PowerGlove was a failure. It didn't sell all that well, nor did it lead to any must-have games that would utilize it. But it was the technological forerunner for the Wii's innovative controller system, and it became a pop-culture icon.

Using a mix of touch sensors and visual sensors it was designed to turn human movement into onscreen controls, but it never quite got the point of being accurate enough to be fun. In fact, in many cases it outright failed.
