I can imagine that are many different stuff to test and they can be very complicated, and I am really sorry if I made it look like I find HCI research is a trivial matter. By the way, the experiment I referred to as trivial is explained in http://www.asktog.com/SunWorldColumns/S02KeyboardVMouse3.html.
