PositionMe

Indoor positioning data collection application created for the University of Edinburgh's Embedded Wireless course. This repo contains the modifications I've made to the positioning app to fulfill the coursework 1 criteria. It involved using sensor data to create a live indoor positioning view so the user can plot a path as they collect indoor positioning data within the Univeristy buildings. This required applying knowledge of the Google Maps API See the assignement pdf for more details.

v1.4

• Correction fragment now keeps floor plans intact which helps user to align trajectory to the floor plan.
• UI updates made so up and down buttons blend in with theme.
• Fixed bugs where certain buildings weren't displaying the floor map correctly.
• Implemented toasts which alerts user that auto floor changes are disabled if using the up and down buttons
• Implemented travelled distance indicator on maps fragment

V1.3

• Features 2a-2e all implemented and working
• Testing carried out and can confirm all floor plans automatically update based on elevation changes.
• Start location automatically centres just outside nucleus to make testing easier, marker can be changed by dragging and dropping as usual.

TODOs

• If time allows, modify the corrections fragment to keep map state from maps fragment to allow easier correction of trajectories.

V1.2

• Features 2a-2b successfully implemented and working.
• User is able to enter and exit building and floor plan will display/ disappear respectively.

TODOs

• 2c-2e still needs to be implemented.
• Test entering and exiting MurrayLibrary and remaining buildings to see if floor plans display correctly for them.

V1.1

• Features 1a-1d from requiremenrts document implemented and working.
• Created a new Maps fragment which user gets directed to via a "Live View" button on the RecordingFragment
• Plots a live view of the path traversed by the user as well as their orientation based on PDR values
• Displays live error distance between PDR location and GNSS location

TODOs

• Implement features 2a-2e from the requirements document
• I.E. use GroundOverlays and layer floorplans on the map, impelement automatic map overlay when usxer enters buildings
