The problem that we aim to solve is the issue of indoor navigation in the Engineering Complex. Currently, it is easy for new students or visitors to get lost in the maze-like Engineering buildings. Our proposed solution aims to make the Engineering spaces more accessible and usable by helping students and visitors get to where they need to be.

The design content of our project involves a front-end mobile application as well as a back-end framed work that is used for localization. Should our solution utilize existing infrastructure like wifi or use no additional infrastructure like the camera based solution, we would include creating data gathering hardware. For the bluetooth solution, our project scope includes the design of physical beacons to install on site. Our goal is to successfully navigate students to their destinations in a user friendly and low footprint manner.

We have since settled on utilizing Wifi, Pedestrian Dead Reckoning (PDR) and magnetometer for our localization. Wifi scans available access points every 30 seconds and provides use with an update of the users absolute position. To fill in the gaps between Wifi scans, we utilize PDR and magnetometer localization to provide relative motion. PDR counts the steps a user takes and their bearing to predict their location. Magnetometer detects the change in magnetic field as the user moves to estimate the users motion.
