We extended the mobility monitoring tool LifeMap [3, 7], for data collection in smartphones. LifeMap continuously collects a user’s mobility every two minutes using WiFi, GPS, and cellular sensors. We added an image-capturing functionality to collect images captured by users. LifeMap visualizes the visited places along with collected data on map and list form, as shown in Figure 5. Users can confirm and delete collected data at each place for privacy issues. We also developed a crawler to collect location, as well as interaction data from social networks, such as check-in histories, posted tips, pictures, and basic user information. To preserve privacy issues, we only used public data without private authorization.
