Mobile smartphone applications may assist seniors in their mobility and connect them with the community. This project involves the development of a new version of the Urban Connector application to: (1) identify a metric of social connectivity from the mobility perspective from existing literature; (2) update the Urban Connector application to consider data privacy policies when automatically collecting mobility data; and (3) design a survey and an analysis framework to gather information on how seniors use the Urban Connector application for social connectivity from the mobility perspective.
