Interactive Visualization and Capture of Geo-Coded Multimedia Data on Mobile Devices

VisualCommunity: a platform for archiving and studying communities

“…1 . The geo-coded video and narrative data can be conveniently captured by a GeoVideo mobile APP, which is available for iOS or Android platforms [ 11 ]. Section 4 shows its functions.…”

“…To help address this gap we develop a computational platform, named VisualCommunity, for easy community data capture, archiving, and analysis. This platform includes (1) a mobile APP (named as GeoVideo) helping users capture geo-coded video and narrative data with their mobile phones [ 11 ], and (2) a visualization system for easy and interactive study of the various acquired data. AI tools for semantic image segmentation and speech transcription are included, so that users can automatically process the collected data to extract visual and textual semantic information, which can also be linked to the associated location on the map.…”

“…A key aspect of VisualCommunity’s creation is usability and transferability amongst users; domain experts were consulted throughout its development process; the mobile APP has been developed for both iOS and Android systems and is available in the corresponding APP stores [ 11 ]; and the visualization system is publicly available for download onto desktops or laptops environments. In this paper, we introduce the design and development of the platform, and present examples to illustrate functionality and effectiveness.…”
