17. Today’s mobile computing technology provides a rich toolset for significantlyenhancing theuser experience with library digital collections

18. Mobile Enhanced Digital Collections

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

20. 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

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 • Reduce the disconnect between user and object brought about by digitization

22. Two Basic Technologies • Touch-based Interfaces • Geotagging + Geolocation

23. Touch-based Interfaces • “Swipe” gesture • Interact “directly” with digital objects Example: Classics Source: iTunes App Store

24. Touch-based Interfaces • “Swipe” gesture • Interact “directly” with digital objects Example: Classics Source: iTunes App Store

25. Touch-based Interfaces • “Pinch and zoom” • Fluid interface for navigating image details Example: Love Art: National Gallery, London Source: iTunes App Store

26. Touch-based Interfaces • “Pinch and zoom” • Fluid interface for navigating image details Example: Love Art: National Gallery, London Source: iTunes App Store

30. The WolfWalk Project

31. 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

41. Demo

42. Implementation

43. 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

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

45. Geodata Processing

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

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

48. 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)

49. Future Directions

50. Augmented Reality • Live camera • Compass • Geotagged content Example: Layar (Google Android) Source: Layar.eu
