When Sony announced PlayStation Move at E3 2009, it was hard not to be cynical. By this time the Wii was selling more than Xbox 360 and PlayStation 3 combined, and it was all down to a feature Sony (and Microsoft) had written off as a pointless gimmick: motioncontrol. Now here was Sony’s Jack Tretton enthusiastically spruiking the PlayStation’s own motioncontroller – a wand similar to the Wiimote, but black and capped with a coloured sphere that looked like an iridescent afro. Again: it was hard not be cynical. But Sony’s wand had something the Wiimote didn’t: the PlayStation Eye. Successor to the EyeToy and built using better versions of basically the same technology, the Eye sports a higher resolution and framerate than its progenitor, as well as a wider field of view and greater sensitivity to movement. Used in conjunction with Move, it recognises the colour and size of the controller’s afro, which it combines with data from the wand’s internal sensors to accurately calculate its position in space. The result is smooth and responsive motion tracking superior to the Wiimote’s – superior even to the Wiimote with MotionPlus add-on.
(To illustrate this fact for yourself, simply grab a copy of Sports Champions 2 and try out the boxing – you'll see that it's much more responsive and satisfying than the Wii Sports version. Same goes for tennis, which is actually pretty fun.)
In 2013, Sony announced a successor to the PlayStation Eye: the imaginatively titled PlayStation Camera for PlayStation 4. With two 1280 x 800 motion tracking cameras, an even wider aperture, and better depth and movement sensing capabilities, it and the Move wands form the core of the four piece tech ensemble that is PlayStation VR.
