The EZSort tool helps interface designers organize information for Web sites based on users' expectations gathered from card sorting exercises. It includes two packages: Usort and EZCalc. Usort provides a simple user interface for the card sort study participants to group cards by direct manipulation within a Graphical User Interface. EZCalc analyzes the card sort data gathered from Usort using cluster analysis statistical tool and generates tree diagrams that present clearly the page groupings suggested by the data. The output diagrams from EZCalc feature directly adjustable criteria bars and dynamic feedback on the resulting groupings. This tool is available for download from the IBM Ease of Use Web site.
