摘要：

Two studies of using the thinking aloud method for user interface testing showed that experimenters who were not usability specialists could use the method. However, they found only 28-30% of known usability problems when running a single test subject. Running more test subjects increased the number of problems found, but with progressively diminishing returns; after five test subjects 77-85% of the problems had been found.
