A Survey of Mobile Phone Sensing
Mobile phones or smartphones are rapidly becoming the central computer and communication device in people's lives. Application delivery channels such as the Apple AppStore are transforming mobile phones into App Phones, capable of downloading a myriad of applications in an instant. Importantly, today's smartphones are programmable and come with a growing set of cheap powerful embedded sensors, such as an accelerometer, digital compass, gyroscope, GPS, microphone, and camera, which are enabling the emergence of personal, group, and community-scale sensing applications. The authors believe that sensor-equipped mobile phones will revolutionize many sectors of their economy, including business, healthcare, social networks, environmental monitoring, and transportation.
