The overall objective of this project is the creation of intelligent, collaborative, interactive information displays for outdoor use. Here intelligent means that information is shown conditional on the current context (meaning demands/wish/request and intentions/aim/ambition of the viewer as well as the characteristics of the setting/surrounding area). By collaborative we mean the capacity to relate the contents presented on a stele to the information shown on other steles, their associated history and the history of the different viewers. The term interactive is defined in this context as a presentation of information depending on active user operation (e.g. language, touch or gesture) and also passive user operation (e.g. approaching, facial recognition, sounds).
