At Sony's press conference at E3 2009, Dr. Richard Marx, the man behind the Eye Toy and the PlayStation Eye introduced the PlayStation Motion Controller engineering prototype, whose intended goal was to add to the Eye Toy's capabilities. The Motion Controller features a trackable glowing sphere on the end of the controller, that the PlayStation Eye can use to determine player's actions. Dr. Marx gave a live tech demo, showing off the Motion Controller's true 1-to-1 tracking by using it to control a variety of virtual items: swords, a flashlight, a tennis racket, a light-whip and a mace (this one was really cool, with the weighted end hanging from the end swinging dynamically).
The tech demo continued with a FPS-style setup which looked awesome and a demo of the ability to use the Motion Controller for drawing, illustrating the accuracy of pencil tracking, which is claimed to be a sub-millimeter accuracy. Drawing can be used to paint, set up things, and move troops around in a fashion that looks like drawing football plays, for example. Demonstrations of using the Motion Controller for sword fighting (and using a shield), using throwing stars and practicing archery all looked cool, as well.
