One of the main problems with those systems is how to adequately support and enhance the spatial interactions of a traveler to new urban areas, which is crucial for successful self-orienting and wayfinding. The methodology employed allows for conceptualizing, implementing and evaluating research prototypes that aim to satisfy the special user requirements. Outlined in this article are the techniques designed and integrated in the developed prototype, the methods used for their evaluation through field-based studies and the challenges encountered during this process. New techniques with a measurable impact on the effectiveness, efficiency and satisfaction of navigation were tested and found to dramatically enhance the sense of personal geo-identification in new places. Examples of those techniques are landmark visibility indication, multi-path routing based on time availability, multi-perspective landmark photos and reverse overview + detail maps. Overall, the outcomes of this research verify the capacity of UCD to help overcoming current usability issues with pedestrian navigation systems. By demonstrating an effective UCD methodology and discussing the lessons learned, we intend to aid the development of next generation navigation appliances.

Field-Based usability evaluation methodology for mobile geo-applications / Corné P.J.M. Van Elzakker in Cartographic journal (the), vol 45 n° 2 (May 2008)  

Public [article]  inCartographic journal (the) > vol 45 n° 2 (May 2008) . - pp 139 - 149 Titre : Field-Based usability evaluation methodology for mobile geo-applications Type de document : Article/Communication Auteurs : Corné P.J.M. Van Elzakker, Auteur ; Ioannis Delikostidis, Auteur ; Peter J. M. Van Oosterom, Auteur Année de publication : 2008 Article en page(s) : pp 139 - 149 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Navigation et positionnement [Termes IGN] cartographie pour écran mobile [Termes IGN] convivialité [Termes IGN] généralisation automatique de données [Termes IGN] Pays-Bas [Termes IGN] positionnement cinématique [Termes IGN] service fondé sur la position [Termes IGN] utilisateur Résumé : (Auteur) An important aspect of a Dutch research project into usable (and well scaled) mobile maps for consumers is presented: the development of an appropriate field-based usability evaluation methodology for the prototype of a geo-mobile application that will be the result of a user centred design approach. Automatic generalisation, required for the user's orientation in space, but also for progressive data transfer, will be an important aspect of the prototype. What is reported here is an effective and technically unique user research methodology, based on a combination of video observation, thinking aloud and semi-structured interviewing. The experiments that have led to this outcome revealed some interesting usability issues that deserve further investigation.

Usability testing dynamics maps / Ioannis Delikostidis in GIM international, vol 21 n° 12 (December 2007)

Public [article]  inGIM international > vol 21 n° 12 (December 2007) . - pp 16 - 19 Titre : Usability testing dynamics maps Type de document : Article/Communication Auteurs : Ioannis Delikostidis, Auteur Année de publication : 2007 Article en page(s) : pp 16 - 19 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] appareil portable [Termes IGN] Bluetooth [Termes IGN] cartographie dynamique [Termes IGN] convivialité [Termes IGN] données multiéchelles [Termes IGN] lisibilité perceptive [Termes IGN] positionnement par GPS [Termes IGN] structure de données localisées [Termes IGN] téléphonie mobile Résumé : (Auteur) Increasing use of geo-information in "smart phones" and PDAs has led to users being disoriented by map displays on small screens, while outdated maps, storage capacity and processing power further inhibit use. High-bandwidth wireless connections resolve some such limitations but map display remains an impediment to wider use. The authors describe research into dynamic presentation of maps at the desired level of detail.
