Kinect is Microsoft’s big gamble with the Xbox 360. The company has put major stock behind the tech. However, despite claims of accurate body tracking, the tech still suffers from recognition issues.
Kinect is actually a very cool concept and a vision of the future. However, the challenge I see with the tech is getting it to perform reliably today. It seems like just about every time it was publically presented something goes haywire.
We have seen Kinect act oddly with different lighting, failing to even register the person properly. Other times we have seen the tech pick up certain individuals while the person standing next to them seems to be ignored.
Kinect seems to also have a difficult time tracking foreign objects when brought close to the body like a piece of paper. This contrasts to the trailer shown at E3 last year of the boy scanning in a skate board into the Kinect.
