Chapter 9. Activity Recognition with Mobile Phone Sensors

While the previous chapter focused on pattern recognition in images, this chapter is all about recognizing patterns in sensor data, which, in contrast to images, has temporal dependencies. We will discuss how to recognize granular daily activities such as walking, sitting, and running using mobile phone inertial sensors. The chapter also provides references to related research and emphasizes best practices in the activity recognition community.

The topics covered in this chapter will include the following:

Introducing activity recognition, covering mobile phone sensors and activity recognition pipeline
Collecting sensor data from mobile devices
Discussing activity classification and model evaluation
Deploying activity recognition model

Introducing activity recognition

Activity recognition is an underpinning step in behavior analysis, addressing healthy lifestyle, fitness tracking, remote assistance, security applications, elderly...
