Using immersive video to evaluate future traveller information systems

An immersive video system that has been developed for the purpose of evaluating future traveller information system (FTIS), in particular, FTIS scenarios that rely on a pervasive computing infrastructure is presented. Immersive video uses multiple video streams captured from a first person perspective at key locations in a scenario. By dynamically reconstructing a user's visual and aural experiences, the immersive video system creates a lab-based framework that captures a number of the contextual factors of real-world mobile information system use. Graphical user interfaces, displayed on a PDA and a wearable display, are used in the evaluation. Both the technical basis of the immersive video system and its application to the study of user perceptions and reactions to pervasive information services are presented.
