final presentation: mobile augmented reality for spatial navigation
DESCRIPTION
A presentation on my final year project. It explains, the processes and investigation into the use of Augmented Reality in an outdoor museum setting, specifically Bunratty Folk Park, Co. Clare. The design is focused on the user, using personas, scenarios, storyboards and the iterative design process.TRANSCRIPT

BUNRATTY FOLK PARK
BUNRATTY FOLK PARK
Irish visitor attraction run by Shannon Heritage
19th century life is recreated
Buildings from the mid-west have been relocated to the 26-land surrounding Bunratty Castle
30 buildings are set in a rural or village setting there.
BUNRATTY FOLK PARK
The buildings are outfitted, as they would have appeared in their era
Old tools and artifacts are displayed around the Folk
Park
Bunratty Folk Park attracts many visitors from Ireland and around the world annually
VISITOR ATTRACTION MOBILE AIDS
Draw attention to the museums unique role as three-dimensional, geographically located place
Mobile guides are designed for assisting people on the move
AUGMENTED REALITY
What is Augmented Reality? Layers digital information to a real world environment
through a camera, creating a mixed reality
Allows for the navigation of a physical area and connected digital space at the same time
Enhance the visitors experience while allowing them to
interact in the real world in natural ways and give a better context of information
AUGMENTED REALITY
In Bunratty Folk Park: Allows the visitor to point a camera at an exhibit, the
device recognises its by it’s location and layers digital information on to the display
3- dimensional virtual objects can be positioned with
real ones on display
Leads to dynamic combination of a live camera view and information
BUNRATTY FOLK PARK NAVIGATIONAL AID
Smartphone PlatformMost people carry mobile phones and are comfortable
with them
Ideal Augmented Reality Technology Global tracking tools Wireless communication capabilities Location based computing Large display for interaction
DESIGNINGFOR THE VISITOR
HUMAN CENTRED DESIGN
Goal of the Navigational Aid Easy to use, clear and understandable Useful to visitors Creating interaction between the visitor and the aid through
the user interface Engage the visitor
To ensure this… It is necessary to understand the visitor of a navigational aid in
Bunratty Folk Park Identify visitor motives and goals while going through the Folk
Park.
HUMAN CENTRED DESIGN
Understanding the technology and Related Works Literature
Similar Technologies Electronic Tours in Museum Settings Interactions design in Outdoor Museums
Understanding the User over time Observations
Interviews
HUMAN CENTRED DESIGN
Findings Most visitors do not use the map Most visitors have mobile phones Visitors want more information View the Folk Park at their own pace Information should be straight to the point Large social interaction within groups
NEXT STEPS FROM RESEARCH
Define Visitors Goals
Define Functionalities of the Aid
Develop Personas – visitors who use the Aid
Develop Scenarios – how the persona uses the navigational aid in the Folk Park
Draw up Storyboards on scenarios

ITERATIVE DESIGN PROCESS
Prototyping and User Testing Low Fidelity Prototyping
Sketches Paper Prototyping Post-It Prototyping PowerPoint Prototyping
High Fidelity Prototyping Wikitude
INITIAL SKETCHES IN PHOTOSHOPPros:• Good for idea generation• Cheap• Concepts seem feasible
Cons:• Not great feedback gained• Photoshop not fast enough for making changes
POST IT PROTOTYPING
Benefits
• Fast
• Cheap
• Prepared to scale
• Buttons can be moved and resized fast
• Gives a more realistic feel for size than a computer screen
POST IT PROTOTYPING
After Assessment:
• Sub Options removed• View Options made bigger

• Selection highlighted in blue
• Home button added for easy navigation to main menu
POWERPOINT PROTOTYPINGBenefits • Used for User Testing• Interactive• Functionalities work when following the story of Scenario 1• Quick• Easy arrangement of slides
User Testing• Participants found• 15 minute sessions screen captured• ‘Talk Allowed’ technique used
• Notes taken
• Post-Interview
POWERPOINT PROTOTYPING Problems Found and Fixed for next Iterative Session
Some exits gave confusion Map information not clear
• Setting a reminder not clear enough
• User feedback taken in to consideration
HIGH FIDELITY PROTOTYPING
Test usability with navigation, map and some AR features
Feedback on the use and feel of the aid in hand
WIKITUDE
Popular augmented reality browser for mobile devices
Mapping Point of Interest abilities Multiplatform Shows the points of interest of
Bunratty Folk Park Markers can be selected in and an
information pop-up appears
WIKITUDE
User Testing Application well received
Understandable
Participants playful with the technology
FINAL CONCEPT DESIGN
FINAL DESIGN CONCEPT
Key Issues Fix issues found in previous Iterative
sessions
Design with design guidelines in mind
Appealing to the Visitors Mental Model Icon Design
Aesthetic Design Colour/Font Buttons Look
VIDEO PROTOTYPE
Flexible tool for capturing the use of an interface
Elaborate simulation of how the navigational aid will work
Does not need to be realistic in every detail
Gives a good idea of how the finished system will work
FUTURE WORK
Additional High Fidelity prototyping
Investigate further tracking methods
Build the navigational aid for a smartphone
Add a social feature where visitors can leave their trace through the aid
Short movies dotted around the Folk Park that visitors can view
