Abstract
The objective of this thesis was to design and explore the implementation of an indoor positioning and tracking technique that was low in cost, relying on Bluetooth Low Energy (BLE) sensors, and to integrate it into the Society of Devices Toolkit (SoD-Toolkit) developed at the Agile Surface Engineering lab at the University of Calgary. The resulting system maintains a database of all tracked and untracked users, and uses the signal strengths of pre-positioned BLE beacons to estimate the user's location in an indoor environment. Through an evaluation of the proposed technique, we observed an accuracy of approximately 0.86 meters when a user's average distance to each Bluetooth beacon was less than 1.5 meters. The technique was, also, successful in achieving an 80% tracking accuracy across disjoint tracked spaces when the user density in the space is kept below 0.17 users per square meter, suggesting it could prove to be a practical alternative and/or complement to existing indoor positioning systems.
