The multiple colours are based on timing. If the guy on the right had lifted his hand at the wrong time, it would have reversed their colors. Basically, the selection of a colour is a click, which requires a down and an up event. It associates it with the pointer that creates the next down event. Tuning the timing on these systems is a pain. You may have noticed a glitch where, when they were both drawing in the same window, a grey line was created between them.

Of course, but the question was - How does it remember? It's not like dragging a mouse. You can lift up your hand, and proceed at another point. So, how do you know which finger is which pointer, if you will. Actually, in the meanwhile, I found out. Turns out that each man has a different electric potential (different charge), so on that, it determines the user. But if you do it with two hands (1 user), the charge is same, so there's no way to determine which hand you're using at what point.

I'm no expert on this, but my best bet is this: That drawing app is designed for MPX, so it knows that there is more than one pointer. When it's drawn on, it "remembers" what pointer selected what color.

ok, not bad... does the video projection need to be done in front and the ir behind or can you do it the reverse way around? I guess not or the ir would be in shadow all the time... I spose it has its uses.
