Original design only did everything.
An early prototype for Sony’s Move controller featured a thumbstick and a trackball, among other bells and whistles.
The revelations come courtesy of a Sony patent dug up by PlayStation Lifestyle.
Regarding the thumbstick, the patent clarifies, “In some embodiments, the joystick 114 is used to control aspects of a game console such as manipulating an onscreen cursor. In other embodiments, the joystick is used to control movement or actions of onscreen avatars.”
