Sega Activator

The Sega Activator was a 1993 infrared motion controller—an octagonal ring on the floor—that barely registered 20% of punches and completely ignored kicks, turning Street Fighter II into an interpretive dance. It cost $80, which is 30% cheaper than the Kinect's bundle impact, yet delivered zero competitive value. This peripheral is even more frustrating than #3 R.O.B., which at least performed its single function slowly, while the Activator failed at its core task entirely.
