As Imaizumi described, the ideas were figuratively -- and literally -- shocking. "We tried running electric shock waves, install a pulse reader ... we also tried to build a controller that's receptive to the strength of the [player's] grip," he divulged. "We tried a lot, even a transforming controller." While it's too bad the truly shocking DualShock will never see the light of day, at least we may now know where Nintendo got the idea for its pulse reader: Kojima's dumpster ...
Back to the video, Imaizumi also extolled the virtues of Project Natal, mentioning its ability for gesture, voice and color-based interaction. But, as far as we know, Natal doesn't have the ability to zap players with electric shocks. That's just never gonna happen. (Uh-oh ... did we just say -- yep. Never say never again.)
