Description

Feature info is an interactive map tool that allows viewing background information about a map feature in response to a user action. Mobile devices come with a number of limitations, e.g. small screen real estate and the variety of screen sizes, that can affect map and feature info usability. Existing recommendations for feature info design [1], [2], [3] focus mostly on content, i.e. effective communication of data, leaving the “interaction design” aspect overlooked. This Master’s Thesis attempts at improving the visualization and usability of feature info interfaces in the context of mobile tourist applications and presents nine feature info design guidelines that address specific usability problems. The problems were identified through heuristic evaluation of five tourist applications and a user interview. Literature survey and two usability experts provided ideas regarding how several of these problems can be resolved. Three guidelines were evaluated in a lab-based usability test with twenty participants. On average, assessed guidelines demonstrated a significant positive effect on feature info usability by decreasing task completion time by 33% and increasing task completion rate and System Usability Scale (SUS) score by 26% and 28% respectively. Proposed guidelines are not restricted by any specific use case and can be applied to other application domains. Researchers and business practitioners can use the guidelines as a reference in their daily work.
