Microsoft has claimed that Kinect is capable of true 1:1 tracking - and that the system responds to movement "as fast as pushing a button".
The comments echo those of Dance Central creators MTV/Harmonix, who said earlier this month that the game follows your movements "as if you're in a mirror".
MS Kinect boss Kudo Tsunoda said that Kinect was already capable of 1:1 - and that it didn't need "fixing" to achieve it.
He told Xbox360Achievements: "We've done tests back at the office where we have a TV, flash a light on the screen and we'll have a controller, and have someone there hitting a button, and someone with Kinect clapping as soon as they see the light on the screen, and both things go just as fast as one another.
He added: "We already have the 1:1 stuff working really well and the response time is just as fast as pushing a button or making a gesture."
Kinect is due for release on November 10 in the UK - five days after the US.
