Intelligent user interface, AI, artificial intelligence, beyond Clippy
Two research articles on adaptive interfaces:
- the first one shows that accuracy is more important than predictability to achieve a useful interface.
- the second studies several alternative designs for adaptive interfaces, and finds a dedicated "smart menu" to be the best option.

Predictability and accuracy in adaptive user interfacesWe present a study that examines the relative effects of
predictability and accuracy on the usability of adaptive UIs.
Our results show that increasing predictability and accuracy
led to strongly improved satisfaction. Increasing accuracy
also resulted in improved performance and higher utilization
of the adaptive interface. Contrary to our expectations,
improvement in accuracy had a stronger effect on performance,
utilization and some satisfaction ratings than the improvement
in predictability.
...fast and largely mechanical
interactions caused users to pay more attention to the operational
properties of the interfaces. For example, in the
more complex and more slowly-paced interactions of the
first experiment, users were less concerned with distance
between the extra toolbar and the original location of the
adapted buttons but they frequently commented that they
appreciated that all relevant functionality was grouped in
one place, allowing them concentrate on the task rather
than on navigating the interface.
...it is surprising that Greenberg’s design proved
successful, since it drastically restructures the interface
after each adaptation. This result might be explained by
the very high complexity of the interface (a hierarchical
menu with over a thousand leaf elements), which prevented
the users from developing strong motor memory
for the location of different elements.
