Until recently, this has mainly been applied to static and non-cartographic stimuli, but due to technological developments and reduced cost of equipment, interactive and cartographic applications are now feasible. Li et al. (2010) suggest a new analysis method which applies Hägerstrand’s Space-Time-Cube (STC; Hägerstrand, 1970) to eye movement data. However, in an interactive three-dimensional STC, identifying and exploring key behaviours can be difficult. In order to ameliorate these difficulties, we propose a variation of the STC method, which uses two-dimensional projections of the STC onto the XT and YT planes. These two-dimensional projections are found to facilitate rapid identification of significant patterns in the data set. A prototype implementing this and other dynamical methods has been developed, and is presented with examples illustrating the benefits of working with two-dimensional projections of the STC.

Vertical colour maps – A data-independent alternative to floor-plan maps / Alexander Salveson Nossum in Cartographica, vol 48 n° 3 (October 2013)  

Public [article]  inCartographica > vol 48 n° 3 (October 2013) . - pp 225 - 236 Titre : Vertical colour maps – A data-independent alternative to floor-plan maps Type de document : Article/Communication Auteurs : Alexander Salveson Nossum, Auteur ; Hengshan Li, Auteur ; Nicholas A. Giudice, Auteur Année de publication : 2013 Article en page(s) : pp 225 - 236 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] carte d'intérieur [Termes IGN] couleur (rédaction cartographique) [Termes IGN] couleur à l'écran [Termes IGN] positionnement en intérieur [Termes IGN] représentation cartographique 3D [Termes IGN] visualisation cartographique Résumé : (Auteur) Location sharing in indoor environments is limited by the sparse availability of indoor positioning and lack of geographical building data. Recently, several solutions have begun to implement digital maps for use in indoor space. The map design is often a variant of floor-plan maps. Whereas massive databases and GIS exist for outdoor use, the majority of indoor environments are not yet available in a consistent digital format. This dearth of indoor maps is problematic, as navigating multistorey buildings is known to create greater difficulty in maintaining spatial orientation and developing accurate cognitive maps. The development of standardized, more intuitive indoor maps can address this vexing problem. The authors therefore present an alternative solution to current indoor map design that explores the possibility of using colour to represent the vertical dimension on the map. Importantly, this solution is independent of existing geographical building data. The new design is hypothesized to do a better job than existing solutions of facilitating the integration of indoor spaces. Findings from a human experiment with 251 participants demonstrate that the vertical colour map is a valid alternative to the regular floor-plan map.

Developing a framework for describing and comparing indoor maps / Alexander Salveson Nossum in Cartographic journal (the), vol 50 n° 3 (August 2013)  

Public [article]  inCartographic journal (the) > vol 50 n° 3 (August 2013) . - pp 218 - 224 Titre : Developing a framework for describing and comparing indoor maps Type de document : Article/Communication Auteurs : Alexander Salveson Nossum, Auteur Année de publication : 2013 Article en page(s) : pp 218 - 224 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] analyse comparative [Termes IGN] carte d'intérieur [Termes IGN] données descriptives [Termes IGN] positionnement en intérieur [Termes IGN] visualisation cartographique Résumé : (Auteur) Traditionally, research on cartography has primarily been focused on visualisation of outdoor environments. Recently, however, indoor cartography has increasingly attracted attention both from the academic world and from commercial enterprises. Indoor cartography calls for markedly different visualisation strategies. Frameworks for describing map communication and use exist for general maps. But so far, no such framework exists for indoor maps. This article presents and discusses several map types for indoor spaces found in the literature and commercial products. The different characteristics of each one are identified and described. On this basis, a framework for indoor maps is developed and presented. Arbitrary indoor maps can be described by their properties using the framework. This allows indoor maps to be compared and described using a common platform.
