Intelligent User Interfaces
The term intelligent interface is used to refer to user interfaces that respond flexibly to events in some
purposeful way.
![Page 5: 6.1 Intelligent User Interfaces: achievements and challenges](https://reader035.vdocument.in/reader035/viewer/2022062309/56815736550346895dc4d899/html5/thumbnails/5.jpg)
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.

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

"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

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

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