  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

  28. Geotagging + Geolocation • Geographic navigation of content • Current location as as a content filter Example: Zillow Source: iTunes App Store

  29. Geotagging + Geolocation • Geographic navigation of content • Current location as as a content filter Example: Around Me 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

  32. WolfWalk Content First freshman class posing in front of Holladay Hall (1890), NCSU University Archives Photo Collection

  33. WolfWalk Content View of card catalog in D.H. Hill Library (1972), NCSU University Archives Photo Collection

  34. Motivation

  36. Markus Wust, Content Lead for the WolfWalk Project

  37. Jason Casden, Lead Developer for the WolfWalk Project

  38. Demo

  39. Implementation

  40. 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

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

  42. Geodata Processing

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

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

  45. 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)

  46. Future Directions

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