4 Personalization of Services
Personalization is a key feature that facilitates the use of complex services on mobile devices (Short 2000). Personalization in CRUMPET includes • adaptation to the user's tourism-related interests and to other preferences; • adaptivity, i.e. automatic update of the user model based on the user's interaction history; • location-awareness, i.e. the system's awareness of a user's current spatial context. The latter feature is presented in more detail in section 5.
