Thi sounds stupid

I have a silly question.  How does the focus ring on the color qcam work? 
Like if I want to focus for a closer distance which way do I turn it.  My
problem is that I'm running a setup here that won't allow me to view my
pictures on the machine that the camera is plugged into so it's not like I
can set up xfqcam and then focus.  Any suggestions appreciated.
