I had a go on Kinect Joy Ride yesterday, it was fun for a bit but didn't feel particularly engaging. I couldn't see it having much replay value.

It’s made of two main parts: a projector and an IR VGA camera. The former bounces out a laser (don’t worry, Microsoft insists it’s safe) across the entire field of play, which the camera picks up to separate you from your sofa on what’s called a ‘depth field.’ It’s essentially all the pixels that Kinect gets back as IR noise measured in varying colour dependant on how close they are to the system. That way bodies appear a bright shade of red, green etc, and things further away appear grey.
The software takes this image and runs it through a host of filters so that Kinect can work out what’s a person and what’s not. The system follows a basic system of guidelines, such as ‘a body is from x-foot tall to x-foot tall’ and ‘a person has two arms and two legs’ to work out that your coffee table or dog aren’t extra players. It’s also taught to be able to pick you out if you’re wearing baggy clothes or have hair coming over your shoulders. When we saw this as the developers see it, it was impressively accurate at sussing out each body part (right shoulder, for example) from not much information.
Motion tracking is never completely clean – how good is Kinect?
It's a very clever system that they've got. They look at the depth data, they work out fairly quickly if it's a human, and then they apply their algorithms to give you all the bones or whatever. And if you're standing up in front of it, it kind of works, and now with the new software libraries, if you're sitting down on the sofa, it works. OK, so one big thing that people were questioning was whether you could sit on the sofa. The new libraries work, but there are certain things, like in our fitness game, where you sit on the floor where it kind of gets confused. But the most expensive motion capture systems you can get out there, probably Vicon, it's like: you can break those as well, and that's why you employ clean up animators to go an fill in all the little gaps and stuff like that. So, we don't have the luxury of having that offline clean up ability, we have to do it live.
how did you get to have a go on joy ride????
go on tell us![]()

One important factor here - Kinect is just a method of providing data to software. We all know software can evolve, change and get better. So just as the games have gotten better since launch in 2005, so will Kinect titles.![]()

Personally I think there's some very clever stuff going on and there's way more hardware in the camera than I thought. Some of the voice recognition / tracking stuff is amazing.

As far as Microsoft is concerned they know that they'll have to lose money to make money especially when up against stiff competition.Agree with you ... This definitely looks like another loss leader for microsoft ... You're getting some pretty nifty tech for £130. Looking forward to it being hacked and driven on a PC for more practical applications
I thought I was tight on these forums but WTH ! - I'm really surprised at how many forum members think that this is 'overpriced' but would rather pay £400 for a fantec wheelAs far as Microsoft is concerned they know that they'll have to lose money to make money especially when up against stiff competition.
Personally I've wasted a lot more $$$ on bits of plastic and PCBs in my time this is just a drop in the ocean by comparison.
Roll on November, roll on hacking this beaut.
There is nothing new in the tech at all a lot of the functions have been around in expensive web cams for long time they have just taken a load of different parts and packed them into one package.
