This project is a continuation of a previous project entitled “Geographic relevance visualisation in mobile applications that developed methods of representing the relevance of geographic information in map representations. The objective of this project is to evaluate these methods and developed representations with human subject experiments.

Geographic information is recently ever more used on mobile devices, such as Smartphones. Consequently mobile services building on and employing geographic information, such as location-based services (LBS) or map services have been and still are developed. Yet, most of these services lack a clear concept of geographic relevance, its application for filtering superfluous information, and its appropriate explicit representation. Investigating the fundamental aspects of geographic relevance is not solely fruitful for further developing today’s mobile geovisualisation services, but may also contribute to other fields within Geographic Information Science (GIScience).

We aim at refining the development of and empirically evaluate methods and metaphors for the effective representation of geographic relevance in mobile geovisualisation applications and services. Drawing upon and extending previously developed techniques we may transfer knowledge and deepen the integration of methods currently being developed in complementary research fields such as geographic information visualisation and mobile geographic information seeking, and time geography.

The fundamental research question of the project is how we can support spatio-temporal based decision-making in mobile situations and mobile user activities by employing geographic relevance? The more specific research questions can be formulated as follows:

 - How effective and efficient are representations of geographic relevance?

 - Are such visualisations supporting mobile users with limited cognitive processing capacities?

Main outputs are expected in three areas: 1) additional knowledge about adapted map representations on mobile devices, 2) new insights how relevance metaphors for geographic relevance work, and 3) a set of methods for representing geographic relevance.

This project is likely to make fundamental contributions at the intersection of GIScience, including (cognitive) geovisualisation research, and applied adaptive, mobile geovisualisation service development, deployment, and use. The proposed research will provide answers to the essential research question “How can we efficiently employ and represent geographic relevance to communicate spatio-temporal information within a mobile context”? The outcomes of the project will specifically lead to a better understanding of the nature and applicability of the relevance concept in GIScience. Capitalising on an interdisciplinary approach, this project will draw upon expertise in GIScience, geovisualisation, cognitive psychology, computer science and related fields. This research may foster the advancement of knowledge in two complementary fields – GIScience with geovisualisation and experimental psychology. We expect the developed relevance representation methods to be of immediate use to a wide range of application areas dealing with geographic information communication.

In a broader scope, better understanding of visual information processing involved in using mobile displays and extracting knowledge from graphics is fundamental prerequisite for supporting mobile users during navigation, in mobility related activities, and for rapid decision-making processes. Efficient representation of geographic information supporting cognitive processes in everyday life situations should be an urgent objective for an information society reliant on geographical knowledge and geographically informed decision-making.

Abstract

Synopsis: With this proposal we seek a one-year extension of a previously three year, SNF-funded project entitled “Geographic relevance visualisation in mobile applications“. The first portion of this project had an initial duration of three years (01.01.2009 - 31.12.2011).Motivation: Geographic information is recently ever more used on mobile devices. Consequently mobile services building on and employing geographic information, such as location-based services (LBS) or map services have been and still are developed. Yet, most of these services lack a clear concept of geographic relevance, its application for filtering superfluous information, and its appropriate explicit representation. Investigating the fundamental aspects of geographic relevance is not solely fruitful for further developing today’s mobile geovisualisation services, but may also contribute to other fields within Geographic Information Science (GIScience). We therefore propose to thoroughly evaluate the so far developed representations of geographic relevance within our group.Research objective: We propose to refine the development of and empirically evaluate our methods and metaphors for the effective representation of geographic relevance in mobile geovisualisation applications and services. This proposed research is based upon previous research aimed at developing novel adaptation methods and visualisation techniques for mobile geovisualisation services. Drawing upon and extending the previously developed techniques we propose to transfer knowledge and deepen the integration of methods currently being developed in complementary research fields such as geographic information visualisation and geographic information retrieval, and time geography.Fundamental research question of the proposed project is: How can we support spatio-temporal based decision-making in mobile situations and mobile user activities by employing geographic relevance? The more specific research questions can be formulated as follows:?How effective and efficient are representations of geographic relevance? ?Are such visualisations supporting mobile users with limited cognitive processing capacities? Main outputs are expected in three areas. First, knowledge integration across complementary research fields (as mentioned above) is carried out at the theoretical level (relevance representation methods of geographic objects), a test bed for developing and implementing methods of relevance representation is implemented, and methods are evaluated with users (empirical evaluation of usefulness and usability). Expected results are 1) additional knowledge about adapted representations, 2) new insights how relevance metaphors for geographic relevance work, and 3) a set of methods for representing geographic relevance.
