Playstation Trackball Controller

This is a conceptual image I created in 2003 to show the feasibility of placing a trackball on the Playstation game controller. Read more about the benefits of the trackball…
If you wish, tell Sony about this idea, and send them the URL to this page.

Videos of the controller in action show comparisons between joystick and trackball precision in the PS2 version of Unreal Tournament. Pictures show a Playstation 2 controller (in developmental stage, judging by the rough exterior), which has had its right thumbstick replaced by a trackball.
According to a press release on the web site, the new controller technology, dubbed REFLEX Control™, is intended for release in Fall of 2005.
