This characteristic is important for navigation, including planning travel, making decisions while en route, and developing a user's cognitive map. But what happens on a small display, such as that of a cell phone, when, instead of seeing the entire area of interest, the user can view only a discrete section of the map at any time? This article presents research investigating the implications of a small display for map use and spatial knowledge acquisition. A research study was conducted with 80 participants using a map to answer distance and direction questions in one of four viewable-extent conditions, ranging from 10°/o to 100% of the map viewable at a time. Map-use results showed that small viewable extents hindered performance with respect to accuracy and response time but had no effect on participants' confidence in their performance on the navigation tasks. Tests of spatial knowledge acquisition showed differences across conditions for recall tasks, but a sketch-map analysis revealed no differences based on viewable extent.

Map design evaluation for mobile display / J. Dillemuth in Cartography and Geographic Information Science, vol 32 n° 4 (October 2005)  

Public [article]  inCartography and Geographic Information Science > vol 32 n° 4 (October 2005) . - pp 285 - 301 Titre : Map design evaluation for mobile display Type de document : Article/Communication Auteurs : J. Dillemuth, Auteur Année de publication : 2005 Article en page(s) : pp 285 - 301 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie numérique [Termes IGN] appareil portable [Termes IGN] carte topographique [Termes IGN] conception cartographique [Termes IGN] ordinateur de poche [Termes IGN] ordinateur portable [Termes IGN] petit écran [Termes IGN] photographie aérienne [Termes IGN] représentation cartographique [Termes IGN] téléphonie mobile [Termes IGN] utilisateur Résumé : (Auteur) How to effectively represent spatial information on handheld mobile devices is a key question, given the increasing use of personal digital assistants (PDAs) and cell phones concurrent with the development of location-based services. The mobile use of digital maps on small displays presents new capabilities and challenges that differ from using paper maps in a mobile setting or viewing digital maps on a desktop computer. This research addresses these issues through a study that evaluated maps on a mobile device used for a field-based navigation task. Map representations at two levels of generalization were compared by analyzing subject performance in a pedestrian route-following task, in which a handheld computer was used as a navigation aid. Subject time and accuracy as well as interaction with the mobile device during the task were measured. The results carry implications for map design for small, mobile displays and identify factors that affect the use of maps while moving. Maps are and will increasingly be used on small displays in mobile contexts for a variety of purposes and in many different environments. The requirements and preferences of mobile users, as well as how these maps are used in different contexts, must be understood in order to inform more effective designs.
