Chapter 1 Human Sensors on the Move

In this section we provide an extensive summary of human sensors on the move, or mobile systems that are designed to collect data from smartphones that users carry in their everyday life. One can rely on people’s own mobile phones to collect data as they are at their close vicinity 90% of the time (Dey et al. 2011). These devices have immense potential to collect rich data about people’s behaviour and habits, as well as their environment. In this chapter, we first outline the general idea of human sensor, then dive into some technical challenge before we present a number of systems to generate context on mobile phones.
