User-centered Design and Evaluation of a Geovisualization Application Leveraging Aggregated Quantified-Self Data
No full textIndividual movement traces recorded by users of activity tracking applications such as Strava provide opportunities that extend beyond delivering personal value or insight to the individual who engages in these “quantified-self” (QS) activities. The large volumes of data generated by these individuals, when aggregated and anonymized, can be used by city planners, Departments of Transportation, advocacy groups, and researchers to help make cities safer and more efficient. This opportunity, however, is constrained by the technical skills and resources available to those tasked with assessing bicycling behavior in urban centers. This paper aims to address the question of how to design cartographic interfaces to serve as mediated platforms for making large amounts of individual bicycling data more accessible, usable, and actionable. Principles of cartographic representation, geovisual analytics techniques, and best practices in user interface/experience design are employed to arrive at an effective visualization tool for a broad urban planning audience. We use scenario-based design methods to encapsulate knowledge of map use practice gleaned from the development process, and conduct a post-implementation, two-part user study with seven domain experts to further assess the usability and utility of the interactive mapping tool
Designing an Experience: Maps and Signs at the Archaeological Site of Ancient Troy
No full textMaps and signage are essential for visitors to understand and appreciate the cultural, historical, and natural importance of a heritage site. Unfortunately, the on-site maps and signage at the archaeological site of ancient Troy near Çanakkale, Turkey, create a poor visitor experience. A UNESCO report found that the site suffered from “poor and confusing wayfinding” and “visual clutter and chaos” (Riorden 2009, 9–10). To understand how the maps and signage failed to help visitors, I completed a content analysis of the maps and signage found at Troy in the summer of 2014, based on recommendations from cartographic semiotics and the field of experiential graphic design. The analysis uses a case study of the archaeological site of Ancient Troy to derive insights into user experience design at preserved sites of cultural or historical significance
