Sony Computer Entertainment will shed more light on its fabled and as yet unnamed motion controller next week during two seperate events at the The Game Developers' Conference in San Francisco.

The first event on Thursday (NZ time) is media only and is shrouded in mystery. The conference schedule also has an "Introducing the PlayStation 3 Motion Controller" session pencilled in for Friday (NZ time) and many PlayStation 3 fans will be hoping the presenting Sony developers Kirk Bender and David Coombes can give more insight into the controller's capabilities.

The Friday session's description says the motion-sensing device will allow gamers to interact with their console in HD using 3D position and orientation tracking, camera input and a controllable RGB LED. It will "bridge the gap between camera, motion and traditional interfaces", Sony says.

If successful the controller should put some serious pressure on the Nintendo Wii, which has dominated the motion controller market in recent years. Microsoft's Xbox 360 motion sensing interface, codenamed Project Natal, is due later this year and also looks very promising. Instead of a traditional controller like the Wii Remote, Nunchuk or PS3 motion controller, Natal will allow players to control games using an RGB camera, depth sensor and multi-array microphone.

Sony has been very protective of its motion controller imagery and specs but I'll be on location next week to update all of you New Zealand PC World readers on the latest news.
