Smart Device-Based PDR Methods for Indoor Localization

Abstract

Smart devices, such as smartphones and smartwatches, are indispensable nowadays for everyone’s daily life due to their mobility and powerful computation capability. Sensors embedded in these devices are relatively low-cost and convenient to carry. Consequently, leveraging the sensors embedded in smart devices has provided new opportunities for indoor PDR developments. In this chapter, we first introduce various types of smart devices and device-based carrying modes. We then describe the types and functionalities of sensors built into these devices, as well as common steps and evaluation metrics in smart device-based PDR methods. Several methods are summarized based on the usage of smart devices, sensors, techniques, and performances. Lastly, we present challenges and issues that remain for current smart device-based PDR methods.
