Cameron Moll posted this on his site, Authentic Boredom. It’s great little video from San Francisco based Punchcut, addressing five considerations when it comes to gestural based interaction. There’s a nice article that also accompanies the video as well that delves further into each of the five points made in the video. I fully suggest everyone gives it a read. Now… if only mobile game developers would take these considerations to heart (#4!) Until then, enjoy your tiny virtual D-pads.
