Progress So Far…

Mid Year AssignmentLiterature Review (Completed)

Project DevelopmentWorking GPS & Compass bearings (Completed)Augmented overlay (Completed)Marker-based tracking (In development)

Issues Encountered

GPS on each phone tested returned a different result

Phones tested on: Nokia Lumia 920 , HTC Surround, HTC 7 Mozart

No useable libraries for marker-less augmented reality for Windows Phone Platform

Determining how marker based tracking can be incorporated to improve location based accuracy

Determining position to overlay virtual objects in viewing space Size and distance for overlaying objects
