For my class on  	<a href="http://www.cs.washington.edu/education/courses/590h/"> 	human-computer interface design</a>, I observed an 	<a href="http://www.cs.washington.edu/homes/map/espresso/">espresso stand in action</a>. Then I attempted 	to observe a subject's <a href="http://www.cs.washington.edu/homes/map/mental-models/"> mental models</a> 	as he navigated a web site.  <br>
