Evaluation of a Mobile MR Geovisualisation Interface

Abstract

This paper presents experimental results of a mobile mixed reality interface designed for geovisualization of 3D realistic urban environments which allows dynamic switching between three visualization domains: a virtual reality; an augmented reality and a mixed reality interface to get the best possible representation for visual exploration. On each domain, four different types of geovisualisation and navigation aids can be superimposed including georeferenced 3D maps, 2D digital maps, spatial 3D sound and 3D/2D textual annotations. Interaction is performed using keyboard, mouse, menus and tangible ways. To gather user requirements about urban and virtual navigation and to assess the effectiveness of mobile interface, a two-stage evaluation was performed.
