Sony has treated a handful of its development partners to more detailed information about the firm’s upcoming motion-control gadget for the PlayStation 3.

Although Sony announced that Motion Control – which is still at the prototype stage – will eventually work alongside the Eye Toy peripheral, Sony has since stated that the Eye Toy will be able to simultaneously track up to four Motion Control units, according to a report by website Kotaku.

Sony has also reportedly told development partners that the motion-capture controller will even include facial-tracking and head-tracking capabilities.

Gamers holding the wand will even benefit from force feedback during gameplay, Sony reportedly told development partners recently. Eye Toy will be responsible for voice input and recognition, Sony added.

A “range of first-party and third-party content” will be available for Sony’s Motion Control, which the firm’s planning to launch during Spring 2010. ®
