It offers a simple case study for pilot human factor experiments in automatic user modelling; it affords the possibility of a device independent menu-selection system; in automatic user modelling are raised, such as the user's perception of a dynamic system, the need of user control and the measurement of user satisfaction. The personalized directory system is being used as a test-bed to examine such issues, and will refine our insight into the human factors implications of user modelling.EngComputer Scienceunknown1983-118-710.11575/PRISM/31182
