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.
