Abstract
Spatial awareness is identified as a key feature of today’s mobile devices. While outdoor navigation has been accessible and broadly used for some time already with the help of GPS, indoor positioning has not yet made it into mainstream life. GPS and other GNSS systems offer accuracy of a scale different to that required for efficient indoor navigation. This research aims to investigate how a number of sensors such as a Digital Compass, Bluetooth and Accelerometer may be combined to calculate device position and orientation to perform directional querying in a spatial database. These three technologies were chosen because they appear in some mobile devices available today and are likely to become even more widespread in the nearest future.
