Adaptive
navigation support is a specific group of technologies that support
user navigation in "virtual spaces" adapting to the
goals, preferences and knowledge of the individual user. These
technologies, originally developed in the field of adaptive hypermedia,
are becoming increasingly important in several adaptive Web applications
from Web-based adaptive hypermedia to adaptive virtual reality.
This paper provides a brief introduction to adaptive navigation
support, reviews major adaptive navigation support technologies,
and presents a sequence of projects performed by our group to
study adaptive navigation support in different contexts.
