Technology Overview

Motion controls and social gaming were the hot topics at this week's Game Developers Conference, the annual convention of game designers, programmers and executives.

Sony shook up the conference with a splashy introduction of the PlayStation Move, a new wand-shaped PlayStation 3 motion controller system that will rival Nintendo's popular Wii.

Sony showed off several games that use the new system, which utilizes a PlayStation Eye camera to detect players' movements. Among them were the action brawler "Motion Fighter," over-the-top party game "TV Superstars," athletic simulator "Sports Champions," mini-game collection "Move Party," third-person shooter "SOCOM 4" and wacky downhill racer "Slider."

"It's just scratching the surface," said TechSavvy technology analyst Scott Steinberg. "If you talk with game developers themselves, they will tell you they don't know what they're quite capable of doing because they're just coming to grips — no pun intended — with the hardware itself. At this point, we're just seeing some very early possibilities."

The biggest buzz, however, seemed reserved for social gaming, a form of easy-to-play online multiplayer games. With the success of such social games as the real-time crop-growing simulator "FarmVille" and the gangster role-playing saga "Mafia Wars," several conference sessions this year were devoted solely on how to tap into the gaming world's Next Big Thing.

"I feel like people are motivated more this year," said Game Developers Conference director Meggan Scavio. "They seem genuinely excited to be doing what they're doing, and there's an air of anticipation. I think they've discovered there's still new business models out there. There's still new ways to develop and make games that they hadn't thought of before."

There's still wow factor, too. On the sprawling expo floor, attendees gawked at the VirtuSphere, a huge hamster ball-like virtual reality doodad that allows users inside to control a virtual character by walking around inside it. Folks also crowded in front of a mock living room populated with hipsters rocking out with the upcoming guitar game "Power Gig."
