Sony patents 'Eyepad,' a Moveenabled PS3 tablet controller
It's important to remember, especially in situations like this, that the existence of a patent does not necessarily correlate to the existence of a product, or even a company's desire to build what it has patented. So, with that in mind, let's take a look at Sony's ridiculously named PlayStation 3 tablet controller patent.

The device Sony refers to as an "EyePad" in its patent application, seen in the sketch above, would theoretically come equipped with the usual trappings you'd expect from a PS3 controller: D-Pad, buttons, analog stick, SIXAXIS motion sensors, etc. The more interesting bits, however, are a bit harder to pick out from the drawing.

First of all, those shaded stripes on the edge are not a creamy nougat center, as we had originally surmised, but rather illuminated strips of LEDs or comparable light source. This would allow the EyePad, in conjunction with an EyeToy camera, to function as a PlayStation Move controller.

Secondly, those dots on either corner of the apparent display (which could actually be a normal display, touchscreen or Vita-esque touchpad, according to the filing) are paired stereoscopic cameras. The cameras are arranged in such as way that their respective fields of vision provide a full, 360-degree view of any object placed onto the surface of the EyePad's screen, allowing for objects to be fully scanned in three dimensions and then rendered in game. Theoretically the player could also place their face within this field, allowing for face mapping in character customization applications, for instance.

Again, we doubt this patent represents anything more than a combination of day-dreaming and butt-covering on the parts of Sony's engineers and legal department, respectively, but the ideas presented here are definitely interesting.
