What's Up With The PlayStation Move's Coloured Balls?

The first press shots of the PlayStation Move look delicious, courtesy of the bright coloured balls perched atop the peripheral. Wondering why there's so much variety? So were we.

While many people's first instinct is that the Move will ship with different coloured spheres, or that perhaps they're interchangeable, truth is that while at rest, the ball has a pearly, transparent finish. The different colours come from gameplay situations, as the sphere pulsates and changes hue depending on what's happening on the screen.

Sony's VP of worldwide studios Scott Rodhe told Kotaku that the lights are generated by three LEDs inside the sphere, meaning - in theory, at least - the ball can render pretty much any colour imaginable.

Stephen was playing SOCOM 4 earlier, for example, and the Move's ball went orange. Why orange? Because the controller worked out that there was no orange on the screen at that time, making the Move easier for the PlayStation Eye to detect and for you to make out against the backdrop of the game.

So if you're playing a different game, in a different area, the colour will change. Pretty neat!

How The PlayStation Move Is NOT A Wii Remote [Kotaku]


    ...that's actually a little bit brilliant.

      Yeah it is, but a ball on top of the thing? Why not just give it a slightly transparent case and make the whole thing change colours? At least then it would look half respectable

        Err..i think the point of it being a sphere is so it can easily work out it's position. The position and size of the sphere (would look pretty much like a circle to the camera) would be enough information to figure it out. Combined with the information from the gyroscopes within the controller you can then calculate the orientation of the controller.

          I still dont think the ball is necessary, the pictures show that it's easily big enough to fit into an adults hand so couldnt the PS Eye just pick up whatever light your hand wouldnt cover? Even if that limited the accuracy, the magnetic thingy and the accelerometer would still put it far above the wiimote in terms of accuracy
