Sony has officially revealed the name of its upcoming motion-control peripheral at the Games Developer Conference (GDC) in San Francisco today: PlayStation Move.

Shu Yoshida, president of Sony Worldwide Studios, announced the peripheral’s name today along with some features not yet revealed since the device’s announcement at E3 2009. 

Yoshida revealed that the device should be available in the US Fall (between September and December in New Zealand), and will constitute a “more precise experience” for both casual and hardcore gamers. He insinuated that there will be a degree of backwards compatibility with existing PlayStation 3 titles along with the games developed with the Move in mind.

Peter Dille, senior vice president of marketing for Sony Computer Entertainment, also revealed that PlayStation Move will be sold as standalone controllers, bundled with PlayStation Eye camera or with PlayStation 3 consoles.

Sony hopes to release a bundle consisting of a game, controller and Eye camera for under US$100.

Scott Rodhe, vice president of Sony Worldwide Studios, explained that Move allows true 3D rotation, and that the peripheral features buttons and an analogue trigger. There will also be a Sub-controller attachment that bears a striking similarity to the Nintendo Wii’s Nunchuk attachment for its Wii Remotes

A game called Move Party, developed by Supermassive Games, was demonstrated. It uses video capture to create an augmented reality experience for players. Using the Eye camera, it captures the player and places them in a virtual on-screen environment, replacing the wand on-screen with another implement (such as a sword or a tennis raquet).

Rodhe also demonstrated how PlayStation Move can be used on existing games with a demonstration using LittleBigPlanet. One player used a regular Sixaxis PlayStation 3 controller to move a sackboy while another player using a move helped him navigate a level by moving platforms with the Move controller.

Many of the activities demonstrated made use of an orbed controller in each hand for each player. For instance, a fighting game with the working title “Motion Fighters” was demonstrated, which let the player throw virtual punches from a behind-the-back perspective using two Move controllers.
