Just means you need an additional camera to capture the side of the person. I think the image processing route is the way to go because it seems superior to having to hold props all the time. Plus it captures jumps, ducking, etc. which a prop system cannot distinguish from your putting your hands up and down, unless you're wearing something on your head as well or something (like a full-gadget suit, like you said). It can also track your head movements by following your eyes, etc.
