   ABSTRACT     = {Design patterns are recognized in the software 
      engineering community as useful solutions to recurring design 
      problems that improve the quality of programs. They are more and more 
      used by developers in the design and implementation of their 
      programs. Therefore, the visualization of the design patterns used in 
      a program could be useful to efficiently understand how it works. 
      Currently, a common representation to visualize design patterns is 
      the UML collaboration notation. Previous work noticed some 
      limitations in this representation and proposed new representations 
      to tackle these limitations. However, none of these pieces of work 
      conducted empirical studies to compare their new representations with 
      this common representation. We designed and conducted an empirical 
      study to collect data on the performance of developers on basic tasks 
      related to design pattern comprehension to evaluate the impact of 
      three visual representations and to compare them with the common one. 
      We used eye-trackers to measure the developers' effort during the 
      execution of the study. Collected data show that there exists for 
      certain tasks a representation that is more efficient than the common 
      one. We also found tasks for which the common representation works 
      better.}
