This book demonstrates the usefulness of the modern smartphone for providing location aware applications to the tourist as an end user.
During the course of this book it has been demonstrated that the modern smartphone has the accuracy and responsiveness required to provide excellent location aware functionality to the tourist end user. The GPS section outlines how a developer can leverage this functionality to make apps that use close quarter location positioning to help the average tourist in a host of different ways. It has also been demonstrated that bluetooth and other technologies such as QR coding are effective at providing location aware functionality in situations where GNSS(GPS) is ineffective, such as in indoor environments.
Lastly, the book outlines how an engineer could provide augmented location services when GPS is not available by using the RSSI signal from Bluetooth devices.
