When it is useful to build an adaptive computer system? I think a good example is a tutorial system that adapt to the skills of the user. It stores not only the progress of the learning process of a participant, it recognizes the infirmities and can provide him to handle the next chapter better than the previous ones. 4.2 Adaptive computer systems Today we have many adaptable systems, but less adaptive systems, why? Let me list some very relevant reasons for this. • it is very difficult to use the knowledge about a user in an adaptive computer system • in an adaptable system the user decides whether or not he want to adapt something • in an adaptive system the computer system must decide what part of the system must be adapted to support the user The conclusion must be that personalized computer systems should be a mixture of adaptable and adaptive systems. 4.3 A look in the future The demand in the research of HCI is that not the user must adapt to the computer system that he want to use, the system adapts to the preferences and capabilities of the user and infers the intention and goals of him. Another directive is that: ”Wherever you are you take your preferred settings and programs with you and the computer knows you.”. If we want a distributed, personalized computer system we need a distributed user model which we can access over a network. 5 Summary We have seen that we need to collect information about a user in a user model. • information about the user in a platform-independent user model • a distributed UM-Shellsystem • a communication-system between the UM-Shell and the application In the personalization of computer systems we have two main problems: • in an adaptable computer system the user decides about the adaption • adaptive systems must predict the intention of the user In the future we want personalized computer systems that gently adapt to the skills and preferences of the user and if the user want, he can adjust the system in any kind. 8
