Data Science Day @ Columbia University

Maps on mobile/wearable devices often make it difficult to determine the location of a point of interest (POI). For example, a POI may exist outside the map or on a background with no meaningful cues. To address this issue, we present Personalized Compass, a self-contained compact graphical location indicator. Personalized Compass uses personal a priori POIs to establish a reference frame, within which a POI in question can then be localized. Graphically, a personalized compass combines a multi-needle compass with an abstract overview map. In this demonstration, we present a prototype iOS map application with Personalized Compass. Attendees will have the opportunities to interactively use Personalized Compass to perform a series of map-based location and direction tasks.
