2. “Even a good match between person and system is unlikely to last. Tasks change over time and so do we.”

3. Intelligent User Interfaces

4. Intelligent User InterfacesThe term intelligent interface is used to refer to user interfaces that respond flexibly to events in some purposeful way.

5. Intelligent User InterfacesThe term intelligent also includes systems that have explicit human knowledge represented within them.

6. Intelligent User InterfacesIn the sense that an intelligent interface responds flexibly to events, it can be thought of as adaptive.

7. The agent that performs the adaptationthe system specialist the trained user/local expert the end user the system itself

8. The level of concern of the adaptationperceptual and motor skills user goals and meaning the information environment

9. The basic questionswhat is the interface being intelligent about? to what purpose is change made?what is the protocol for agreeing change?who has access to the knowledge employed?

10. What is the interface being intelligent about?

11. What is the interface being intelligent about?The user or the services being provided?

12. To what purpose is change made?

13. To what purpose is change made?Help with skills, goals or the environment?

14. What is the protocol for agreeing change?

15. What is the protocol for agreeing change?How is an adaptation authorised, implemented and evaluated?

16. Who has access to the knowledge employed?

17. Who has access to the knowledge employed?Knowledge engineer,expert or end user?

18. Achievements and challenges

19. Adapting to the user

20. "Excepting the use of psychometric testing it is unlikely in the near or even semi-distant future that any persistent personality or cognitive traits can be derived from monitoring user interaction" Browne 1990

21. Offer the user a tip

22. Offer the user a tip but contain a clear description of the rationale of the adaptation present comprehensive selection and definition opportunities offer a survey of previously performed adaptations allow for future changes to the adaptations. Opperman 1992

23. Adapting to the services

24. Required in domains such as Process Control, where unpredictable events occur

25. Being intelligent about the services

26. Being intelligent about the user's task and the availability of software that could support it.

27. End-user access to the knowledge in the interface

28. Where an expert is working in a complex domain, in which the knowledge is changing following testing, or discovery, then knowledge refinement is critical.

43. “system inferences are made by monitoring the user’s interactions, which typically are information poor.”
