Usability Glossary: adaptive interfaces
Adaptive user interfaces are interfaces that change over time, in
response to how they are used, to improve the quality of the
interaction.
Adaptive systems also include those that detect common user tasks
and make these tasks more accessible.
Any adaptive interface has, at some level of detail, a model of the
user's behavior that is refined, and provides an interaction that fits
the behavior as best as it can.

Présentation d’ADAPTS
Modern interactive electronic technical manuals (IETM)
provide a wealth of information about a system: how it
is constructed, operates, and what do in a case of each
particular problem.
The focus of the ADAPTS, an Electronic Performance
Support System for maintenance technicians integrates
adaptive guidance from diagnostics systems with
adaptive access to technical information, thus
supporting both sides of the process: what-to-do and
how-to-do it.

Problématique
The amount of potentially relevant information could be very big
and it’s a serious challenge for a technician to find the information
that is most suitable to his experience and context of work.
Dynamic assessment of the technician’s knowledge, experience,
preferences, and work context is the focus of ADAPTS.
ADAPTS accepts real-time inputs from the Condition-Based
Maintenance (CBM) system, then plans a course of Action. The
strategy is dynamically adjusted as the technician interacts with the
user interface.

Adaptivité: modèles utilisateurs
The core of user modeling approach in ADAPTS is estimating
technician’s experience with system tasks and components of various
levels – from subsystems to addressable units.
The experience is calculated from various evidences of user
experience collected by the system. To maximize the user modeling
power ADAPTS uses a multi-aspect overlay user model.
The user model independently accumulates several aspects (roles) of
the experience and knowledge of each technician for each component
or task. In total, there are 12 aspects for evaluating user experience
with components and 8 aspects for evaluating user experience
with tasks.
