Adaptation refers to the functionality that a system can adapt itself to the context of use, e.g. for the sake of personalization. Adaptivity goes one step further, i.e. the adaptations are not only performed when the user start using the system but the system will also adapt while it is being used. In other words, the systems will dynamically adapt to actions taken by the user or changes in the context. This is especially useful for the sake of personalization or in mobile environments.
Adaptive systems can be considered as having a tripartite nature: (1) the source for adaptivity, that is, “to what will be adapted?”, (2) the target of adaptivity, that is, “what will be adapted?”, and (3) which techniques and methods should be used for that, that is “how to adapt the target?”.
In the past research has been done of self-adaptive systems (e.g., the PhD work of Sven Caseleyn), and on adaptation in navigation and adaptive hypermedia (e.g., the work of prof.dr.ir. Geert-Jan Houben).
Now, we are focussing on adaptivity for Virtual Reality based web-systems (see e.g., the GRAPPLE project) where the focus is on adaptive techniques for Virtual Reality ("what" to aadapt and "how" to adapt), as well as on authoring tools for specifying the Virtual Reality adaptivity rules ("when" to adapt "what" and "how"). The same principles are now also applied to educational games (see e.g. the CADE project).
