Questions
What is Pervasive Gaming?
Takes gaming away from computer screens and incorporates the physical and social aspects of the real world with the virtual world.
Different types of pervasive gaming Location Based Context Aware Augmented Reality
Why Mobile Devices? Makes use of GPS, Compass and Camera

Research Question
To evaluate the benefits of using markerless augmented reality to improve location sensing accuracy within a pervasive gaming environment.
What is markerless augmented reality? Uses natural features instead of fiducial markers
What do I mean by location sensing accuracy? GPS Compass

“To evaluate the benefits of using markerless augmented reality to improve location sensing accuracy within a pervasive gaming environment.”
Motivation Current augmented reality pervasive gaming
systems only make use of GPS and Compass
Not very accurate[8]
GPS - Up to 100 meters offset Compass – Up to 40 degrees offset. Due to
interfering magnetic fields.
Markerless AR uses previously defined position Object tracking accurate up to 20mm
SA = Selective AvailabilityWAAS = Wide Area Augmentation System

Research Objective
To create a game that makes use of these technologies Minecraft like block game
Create and destroy objects
Test if using markerless AR tracking along with GPS can improve the positioning of virtual objects
Test if objects placed in the virtual world can be found easily in the same spot every time

GPS Location Overlayed AR
Locate Scan Play
Technology To Be Used
Windows Phone 7.5 / 8
Visual Studio 2010 IDE
XNA 4.0
Markerless Augmented Reality Libraries / SDK T-Immersion (AR SDK) Open CV (object tracking Library)
User Evaluation Questionnaire
User Testing Place an object walk away and come back
User Interface Testing Test usability of UI on mobile device
Scheduled Testing over certain time Place an object and come back another day
Termination Criteria
Positive Termination Criteria Every works as planned Smooth integration with GPS and AR tracking
Negative Termination Criteria Markerless AR does not work Unable to combine the two technologies
