Exploratory Visualization Of Smartphone-Based Life-Logging Data Using Smart Reality Testbed
Smartphones are now an integral part of our everyday life - people carry them around almost everywhere every time and use them in diverse contexts. Therefore, a smartphone can be used as a life- logging device that constantly and naturally records people’s life for future reference. We developed a smartphone-based life-logging platform with which users can record diverse contextual information such as smartphone activities, timestamps, locations, and accompanying people, along with other sensor data. Using this platform, we collected smartphone-based life-logs from a group of university students. To enable users to visually explore one’s life-logs based on the multidimensional data gathered from their mobile devices, we designed and implemented a web-based interactive visualization tool. We reported preliminary findings we made through our visualization tool.
