The PSeye is what makes the whole Move system truly 1:1 as in really working in 3 dimensions, far more precise than a Wiimote with motion plus. And you know that thing that happens with the Wiimote, when you lose your pointer on screen 'cause the sensor beam is not receiving the signal properly? That's something that NEVER happens with Move.
PS Eye Specs
New microphone functions
An all-new four microphone array, incorporating multidirectional voice location tracking, enhanced echo cancelling and background noise suppression allows for clear audio chat in even the most noisy of environments, without the need to hold or wear a headset.
Next-generation camera features
A frame rate of up to 120 frames per second allows for super-smooth video and sophisticated low-light operation means that the room doesn’t have to be brightly lit for the camera to deliver crisp, perfectly exposed video. The adjustable zoom lens features a 56º field of view to capture head and shoulders action for close-in audio-visual chat, and a 75º field of view to capture the whole body for a fully physical gaming experience.
