Making memories: applying user input logs to interface design and evaluation

In this paper, we describe our approach to designing interface components that automate the logging of user input. These recorded logs of user-system interactions can serve as a basis for usability assessment, and we present here the usability measures that can be automatically derived from this logged data. Making user logs an integral component of the system data model extends their usefulness beyond providing information on user behavior. In our prototype, logs are used for creating a more collaborative interface by increasing the system's contextual awareness of user interactions.
