Abstract:

This paper describes a software system named STARCAT - for STream Analysis of Responses by CATegory. The system analyzes sequences of user command strings that have been captured in a special timestamped CMS console file user response times, URTs, and system response times, SRTs, are associated with each string strings are assigned - by command name, environment, or experimenter-chosen groupings - into categories and category statistics are reported for one, two, and three-string subsequences. STARCAT provides a new tool, valuable to various interface and system design studies, for the quantitative analysis of interactive terminal performance. Author
