18. Today’s mobile computing technology provides a rich toolset for significantly enhancing the user experience with library digital collections

19. Mobile Enhanced Digital Collections

20. Mobile Enhanced DCs
More than just a small screen version of an existing digital collection

21. 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

22. 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

23. Two Basic Technologies
Touch-based Interfaces
Geotagging + Geolocation

24. Touch-based Interfaces
“Swipe” gesture
Interact “directly” with digital objects
Example: Classics

44. Content Workflow Select sites to be included
Select images from existing digital image collection to represent sites
Author site descriptions
Author image descriptions
Enter content in database
Generate image derivatives

45. Technology WolfWalk Database (MySQL) WolfWalk Data Service (PHP/XHTML)
iPhone OS 3.0 (Objective-C)
MapKit Framework (Google Maps)
CoreLocation Framework (geolocation)

46. Geodata Processing

47. Lessons Learned
Not easy to repurpose existing image metadata (dates, descriptions)

48. Lessons Learned
Not easy to repurpose existing image metadata (dates, descriptions)
Mobile application development is different from website development (installed vs. networked content)

49. Lessons Learned
