The trackit Bar is a scanner for the scanner.
It will track the scanner position in 3d space. This is why no markers are needed on the item itself. The Bar is basically using the Scanner as global marker tracking mode.
The Trackit scanner itself is what scans the item. This works much like any other scanner.
Tripod is used to mount the Trackit Bar.
For Desktop/Laptop only. I cant see this being a mobile phone device.
Yes you would have to avoid blocking line of sight from the Trackit Bar and the Trackit Scanner.
There is a good youtube video from the event that explains something and shows some hands on.
