Microsoft's Kinect motion-sensing Xbox 360 peripheral, unveiled last night at the E3 conference, is targeted toward the emerging casual gaming market, experts believe - leaving Sony's PlayStation Move to cater to hardcore gamers.
The BBC's Rory Cellan-Jones says the PlayStation Move - a much less 'radical' device than the Kinect - offers more precision gaming than the Microsoft peripheral.
Even though the Kinect allows players to turn their bodies into controllers, using gestures to control the action on screen, the device does not offer the same precision that a controller allows when playing video games such as first-person shooters.
The Kinect appears to offer a more casual gaming experience, similar to that provided by Nintendo's Wii gaming console. Whether or not it offers the same precision as the Wii Motion Plus is yet to be seen.
Despite expert opinions, Microsoft certainly reckons its Kinect device will deliver the goods for hardcore gamers too. The company has already announced a compatible game, Metal Gear Solid Rising, in which precision swordplay is king.
Microsoft's Kinect is set to hit the shops for November.
