Today’s mobile computing technology provides a rich toolset for significantly enhancing the user experience with
library digital collections
Mobile Enhanced Digital Collections
Mobile Enhanced DCs
• More than just a small screen version of an existing digital collection
Mobile Enhanced DCs
• More than just a small screen version of an existing digital collection
• Leverages emerging mobile technology to create new and improved interfaces to digital collections
Mobile Enhanced DCs
• More than just a small screen version of an existing digital collection
• Leverages emerging mobile technology to create new and improved interfaces to digital collections
• Reduce the disconnect between user and object brought about by digitization
Two Basic Technologies
1. Touch-based Interfaces
2. Geotagging + Geolocation
Touch-based Interfaces
• “Swipe” gesture• Interact “directly”
with digital objects
Example: Classics

Touch-based Interfaces
• “Pinch and zoom”• Fluid interface for
navigating image details

Geotagging + Geolocation
• Geographic navigation of content
• Current location as as a content filter
Example: Zillow

The WolfWalk Project
WolfWalk in a Nutshell
• Our first attempt to create a geomobile digital collection
• Images sourced from university archives collection
• iPhone app to be released Fall 2009
WolfWalk Content

Motivation
Todd Kosmerick (University Archivist) and Adam Berenbak, NCSU Special Collections Research Center
Markus Wust, Content Lead for the WolfWalk Project
Jason Casden, Lead Developer for the WolfWalk Project
Demo
Implementation
Content Workflow
1. Select sites to be included
2. Select images from existing digital image collection to represent sites
3. Author site descriptions
4. Author image descriptions
5. Enter content in database
6. Generate image derivatives
Technology
• WolfWalk Database (MySQL)• WolfWalk Data Service (PHP/XHTML)• iPhone OS 3.0 (Objective-C)• MapKit Framework (Google Maps)• CoreLocation Framework (geolocation)
Geodata Processing
Lessons Learned
• Not easy to repurpose existing image metadata (dates, descriptions)
Lessons Learned
• Not easy to repurpose existing image metadata (dates, descriptions)
• Mobile application development is different from website development (installed vs. networked content)

• Rapidly evolving development environment (maps)
Future Directions
Augmented Reality
• Live camera• Compass• Geotagged content
Example: Layar (Google Android)

Recent advances in mobile computing are truly amazing.
Experiment!
