Sony plans to release a new motion controller next spring for the PlayStation 3 video game console.
The controller will work with the PlayStation Eye camera, which can track players' voices, faces and body motion. Sony did not say how much the controller will cost.
Motion controllers let people play video games without complex buttons and levers. They were popularized by Nintendo Co.'s Wii when it launched in 2006.
Now Sony Corp., and Microsoft Corp. with its own motion control device, "Project Natal," are pushing past that technology. Natal, which combines a camera, depth sensor, microphone and processor, eliminates the need for any button-mashing device.
