Abstract: Present methods available to user centered design practitioners for gathering information pertaining to end-user usability of computer applications have proven be expensive, labour intensive, time consuming and somewhat ineffective. A usability software tool is described which results in relatively simple and effective feedback of end-users reactions to the use of software applications. A critical event is identified by the user and the screen activity for a period of time prior to the critical event is captured. A file of these screen-clips as well as textual information entered by the end-user is provided to the design practitioner for review and analysis.
