What is adaptation?
• “The idea of an adaptive interface is straightforward.
Simply, it means that the interface should adapt to the
user; rather than the user adapting to the system”
• Adaptation consists in transforming different aspects
of the systems in different levels, according to the
context of use
– For example: concerning the presentation, the contrast can
be adapted according to the preference of the user
• How to consider all the possible dimensions, levels
and contexts?

Cybernetics, Vol 19, n 2, March/April, 1989

Why to adapt?
• ‘One size does not fit all’
• Different contexts of use with different
– Users
• Age, impairments, preferences, profiles…
– Platforms
• Mobile phones, laptops, desktops, idTV…
– Environments
• Levels of light, noise, temperature…
• A context of use: C=(U, P, E)

Adaptivity x Adaptability
• Adaptivity
– Automatic
– Adaptive systems
• Adaptability
– Manually
– Adaptable systems
• Complementary approach
– Mixed-initiative
26

Personalization
X Customization
• Personalization
– Occurs when the system is adapted regarding user
characteristics
• Customization
– Occurs when the users are able to modify the
application according to their needs
• Both concepts can be considered as a subset
of adaptation

Adaptation
means
Re-molding
Redistribution
• UI re-molding denotes any UI reconfiguration that is perceivable to the user and that results from the application of transformations
on the UI (e.g., insertion, deletion, modification)
• UI redistribution denotes the re-allocation of the UI components to different interaction resources
(e.g., for instance in the Painter's palette, the toolbars may move to a PocketPC until the end of the session)

Conclusion of Adaptation:
for what?
• Advantages
– Improve task efficiency and effectiveness
• Optimizes task completion time and rate
• Reduces work load
– Positively impacts
• User’s subjective satisfaction
• Accuracy, human performance
• Predictability, situation awareness
• Shortcomings
– Induces user disruption and generates variability
