Pervasive Gaming with Mobile Devices KARNUNG LIANG SUPERVISOR: DR BRETT WILKINSON
Overview Recap Timeline Development Environment Progress Issues Encountered Project Preview Testing Evaluation Conclusion
Recap To evaluate the benefits of using Marker/marker-less augmented reality to improve location sensing accuracy within a pervasive gaming environment. Is object tracking a viable way to improve location sensing accuracy and stable placement of virtual objects?
Timeline Initial
Amended Timeline
Development Environment Windows Phone 7.8 Silverlight and XNA Visual Studio 2010 WP7.1 SDK Libraries SLARToolkit (Silverlight Augmented Reality Toolkit) OpenCV (Object Tracking Library)
Progress So Far… Mid Year Assignment Literature Review (Completed) Project Development Working 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

Testing Testing period to start in late May to early June Waiting for conditional ethics approval Development not completed yet Three different modes to be tested GPS only With marker tracking With marker-less tracking Survey User Experience
Testing - Evaluation Screenshots of what user sees Time it takes to locate an object Coordinates and bearings of the user Survey
Conclusion & Future Work To be completed Completion of game by end of breakready for testing Testing Marker-less Tracking Future Work Improved Markerless tracking Better gameplay
