4. User Interface Design Environment Adaptive Interface User Model Adaptation Strategy

5. Basic Construct of User Model Using one interaction technique How many successful uses User cancels, requests help => difficulties Which technique used to perform action Repeated patterns How long the user spends on each help session Assumes technique used frequently is the preferred technique

6. Adaptation Strategy Suggestions; user has control Reorganizations made less frequently

7. Role of Built-in Knowledge in Adaptive Interface Systems Daniel Crow Barbara Smith

8. Daniel Crow School of Computer Studies – University of LeedsUniversity of Leeds Pattern identification and machine learning in human-computer interaction

9. Barbara Smith Professor - University of Huddersfield, West Yorkshire, U.K. Professor Interested in constraint programming and related fields of AI, specifically in Algorithms, Problems and Empirical Studies

10. Task-Oriented Interfaces DB_Habits – adaptive interface system Uses command sequences Use small amounts of low-level system knowledge Adaptive - individual modelling with descriptive methods Malleable – adaptation to individual user Collaborative – interface as bridge between 2 agents

11. User Modelling Pattern recognition Assumption: repeated sequences rep. tasks Collaborative dialogue to confirm “task” Identify equivalent commands in logfile Fit between patterns and tasks Pattern freqency Order of tool usage
