Project Natal by Microsoft uses the entire body as the controller.

Expect a battle to emerge among the PS3, Xbox360 and Wii this Christmas -- this time centered around games supporting motion sensing systems.

T&A: Initially announced and slated for release by Sony by Spring of this year, the motion controller of which a prototype was shown at E3 last year, will now makes its debut in Autumn this year, based on news from Reuters and BBC.

This puts its right-smack up against the planned launch of Microsoft’s Project Natal for the Xbox360, which according to Robbie Bach, Microsoft’s President for Entertainment & Devices Division at CES 2010, will launch by end-2010.

Project Natal is a radical controller-less motion sensing system where users use their entire body to navigate their avatars in-game. We’ve covered this as a news post awhile back.

The Sony PS3 motion controller is somewhat similar to the Wii motion sensing controller, except that in the PS3’s case, the PlayStation Eye camera atop the HDTV will detect the movements of a special light-emitting sphere on the controller instead of using infra-red sensors like the Wii.

Expect the console gaming season in Christmas 2010 to be one of the hottest ever as different console manufacturers, and game publishers for the Nintendo Wii, Microsoft Xbox 360 and Sony PlayStation 3, release games that tap on these new motion sensing systems.

Meanwhile, here’s a video of Sony’s PS3 prototyped motion sensing controllers in action at last year’s E3 2009 event in Los Angeles, USA.

Games utilizing the Unreal Engine 3 like Epic Games' UT3 had PhysX support since 2007 but it relied heavily on a PhysX hardware acceleration on the PC. Would a software-based PhysX API and engine take this idea further with the consoles?

CORP TALK: Looks like NVIDIA’s been keeping busy of late. The graphics company has announced the signing of a tools and middleware license agreement with Sony (for the PS3) and Nintendo (for the Wii console).

This roughly means that developers for the PS3 and Wii can now use the NVIDIA PhysX technology software development kit (SDK) to author and preview physics effects in real time while developing games for the platforms. The kit consists of an application programming interface (API) software, with robust physics engine, designed to give developers, animators, level designers and artists greater control over character and object physical interactions.

The scalable nature of the physics engine also means that games will look more realistic, more interactive, persistent (constantly evolving) and natural.  What’s even more interesting is NVIDIA’s aggressive move into the software development side of the console gaming sphere, after battling it out on the desktop and notebook front, regardless (for now at least) of whether the hardware comes with an NVIDIA-based chipset or not.

For a list of PhysX-supported games (for PC/Mac and console) to date, check it out here. One thing’s for sure, hopefully, we’ll see more realistic Sixaxis- or Wii motion-controlled games on the PS3 and Wii respectively. (Editor opinions: 1)

Vijay (HardwareZone.com): There are only two major names for game physics engines - PhysX and Havok. While Havok is free for PC game developers, that price isn’t applicable to integrate it with the game nor is it available free for console game developers.

PhysX charges a licensing fee, but it has extensive support from the team behind it to help optimize physics effects for the required games and integrate the PhysX engine into the game. To the game developers, NVIDIA’s extensive support and commitment is their value propostion to delivering a great game despite the cost involved over Havok.

We do wonder if this tie-up with the Wii for PhysX-enabled games could signal the use of an NVIDIA GPU or platform for the next generation Wii. It’s too early to tell, but there could be a small chance with this PhysX development.
