[WiiFlash] The Wiimote z-Depth?

[Merrill, Jason]

OK, but what exactly are the two points? I don't mean to be dense, but I
thought the IR points were the actual lights inside the sensor bar.  So
what is the difference between an IR point's x and the sensor x?  If
it's actual points in the sensor, then can't you just measure that
distance with a ruler? LOL.  This is confusing. You said, "So if one
point is exactly in the middle of the screen" - how is a "point"
(whatever a point is) in the "middle of the screen" (when the screen is
not part of the detection hardware)?  What then does Sensor X and Sensor
Y mean?
