Towards better requirement definition for multimedia travel guiding applications

There are many current efforts in investigating personalized traveler assisting applications through the perspective of human-centric computing and ambient intelligence. In this work we examine a number of existing approaches within a particular context of travel planning services. Specific attention is paid to the domain of designing tools supporting authored itineraries created by professional and amateur guides or interested travelers who want to share their visit and post-visit experience in the form of multimedia excursions to be accessed from mobile devices. Based on the analysis of existing implementations we propose a set of requirements for advancing human-computer interaction models used in multimedia traveler assisting applications.
