The WWW for eLearning
“Even a good match between person and system is unlikely to last. Tasks change over time and
so do we.”
Intelligent User Interfaces
Intelligent User Interfaces
The term intelligent interface is used to refer to user interfaces that respond flexibly to events in some
purposeful way.
Intelligent User Interfaces
The term intelligent also includes systems that have explicit human knowledge represented within them.
Intelligent User Interfaces
In the sense that an intelligent interface responds flexibly to events, it can be thought of as
adaptive.
The agent that performs the adaptation
the system specialistthe trained user/local
expertthe end userthe system itself
The level of concern of the adaptation
perceptual and motor skillsuser goals and meaning the information environment
The basic questions
what 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?
What is the interface being intelligent about?
What is the interface being intelligent about?The user or the services being provided?
To what purpose is change made?
To what purpose is change made?Help with skills, goals or the environment?
What is the protocol for agreeing change?
What is the protocol for agreeing change?How is an adaptation authorised, implemented and evaluated?
Who has access to the knowledge employed?
Who has access to the knowledge employed?Knowledge engineer, expert or end user?
Achievements and challenges
Adapting to the user
"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
Offer the user a tip
contain a clear description of the rationale of the adaptationpresent comprehensive selection and definition
opportunitiesoffer a survey of previously performed adaptationsallow for future changes to the adaptations.
Opperman 1992
Offer the user a tip but
Adapting to the services
Required in domains such as Process Control, where unpredictable events
occur
Being intelligent about the services
Being intelligent about the user's task and the availability of software
that could support it.
End-user access to the knowledge in the interface
Where an expert is working in a complex domain, in which the
knowledge is changing following testing, or discovery, then knowledge
refinement is critical.

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