"We built a similar gestural interface in our motion capture studio when I was in grad school, and we found more things to dislike about it than one would expect. * It's hard to map natural gestures onto the intended actions. * You have to build in some modal state to all of the gestures so that the user can do things like scratch his nose or turn to face someone without destroying his work. * Constantly motioning with your hands is tiring, and the users' motions become increasingly "sloppy" as a result. * If the application requires text entry, switching to a keyboard while wearing a gloves (or similar) is awkward, and on-screen soft keyboards aren't very efficient. * Even with a bit of practice, the interface was still much slower to use than a traditional mouse and keyboard combination." - Jon Parise
