  1. ECE992: Ubiquitous ComputingLead Review • Why we tag: motivations for annotation in mobile and online media – Morgan Ames; MorNaaman • Flickr and public image-sharing: distant closeness and photo exhibition – Nancy A. Van House • Social uses of digital imagery with a focus on smart phones applicability – LorantFarkas; SeveriUusitalo; Jan Blom • Presented by: Michael A. Farrar • November 18, 2008

  2. Why we tag: motivations for annotation in mobile and online media • Morgan Ames; MorNaaman • Problem: The motivations for why people create semantic metadata (tags) about photo content are unknown. • A new class: Flickr + ZoneTag • Photo organization • Annotation • Sharing environments. • Goal: To determine the motivations. TAGS

  3. Hypothesis: “…the traditional use for annotation, personal organization and retrieval, is now augmented by the ability for users to expose their photos on-line...” • Change VS. TAGS • Why we tag: motivations for annotation in mobile • and online media – Morgan Ames; MorNaaman

  4. Background: Related work and tagging applications of study. • Tagging, paper, taxonomy, Flickr, academic article, ToRead – Marlow et al. • Social vs. organizational incentives • An extension of • From where to what: metadata sharing for digital photographs with geographic coordinates – Naaman et al. • Metadata creation system for mobile images – Sarvas et al. • Sharing of media metadata • Based on spatial/temporal context • Why we tag: motivations for annotation in mobile • and online media – Morgan Ames; MorNaaman

  5. Background (cont.): Related work and tagging applications of study. • Flickr: 5 million users; over 250 million images • Privacy settings • Title and caption assignment • Textual labels (tags) • Searching TAGS • Why we tag: motivations for annotation in mobile • and online media – Morgan Ames; MorNaaman

  6. Background (cont.): Related work and tagging applications of study. • ZoneTag: 500 users; uploading over 45000 photos to Flickr • Upload camera phone images • Context-based tag suggestions • Optional pre-upload settings “Users who are not interested in tagging are not burdened by the extra step and still find ZoneTag useful.” • Why we tag: motivations for annotation in mobile • and online media – Morgan Ames; MorNaaman

  7. Approach: Qualitative examination (interviews). • Results: ZoneTag and Flickr usage. 61% Includes ZoneTag-tagged, Flickr-tagged, and non-tagged images • Why we tag: motivations for annotation in mobile • and online media – Morgan Ames; MorNaaman

  8. Results: Tagging classifications. • Why we tag: motivations for annotation in mobile • and online media – Morgan Ames; MorNaaman

  9. Results: Motivations for tagging. “A clever feedback system…providing the photographer with the satisfaction of…” “…participants mentioned tagging their photos in part to make the tags appear in others’ suggested tag list.” “…tagging was a socially contagious activity.” • Why we tag: motivations for annotation in mobile • and online media – Morgan Ames; MorNaaman

  10. Flickr and public image-sharing: distant closeness and photo exhibition • Nancy A. Van House • Problem/goal: Unclear statement of problem/goal; embedded in previous publications? • “This paper presents an empirical study in progress of the use of Flickr.com, part of an on-going research program on personal digital media, including images.” • “In this paper, we report on early findings of a study of Flickr and put these findings about the uses of new media and technology in the context of photographic practices more generally.”

  11. Background/hypothesis: An earlier work classification of Flickr. • The social uses of personal photography • Memory, narrative, and identity • Reflection and sustainment of relationships • Self-representation • Self-expression • How does Flickr fit in? • Flickr and public image-sharing: distant closeness and • photo exhibition – Nancy A. Van House

  12. Approach: An extension of earlier work. • Interviews and photo elicitation • 12 Flickr users • A convenience sample of acquaintances • Student Flickr users at UC Berkeley • Flickr and public image-sharing: distant closeness and • photo exhibition – Nancy A. Van House

  13. Results: The social uses of Flickr. • Memory, identity, and narrative • Some archive – memory • Others stream – identity; narrative • Maintaining relationships • Audience known by the author • Contacts; groups; commenting functions • Daily logons; email-like TUESDAY, NOV 18, 2008 “One woman said that comments had substantially increased her photographic activity.” • Flickr and public image-sharing: distant closeness and • photo exhibition – Nancy A. Van House

  14. Results: The social uses of Flickr. • Self-representation • Self-expression • Photo exhibition • Discussion: • Distant closeness – staying close to, informed about, people who may be distant physically and/or socially. “I think people perform for the camera…a chance to show themselves…in front of an audience.” “Everyone’s photos: an ever-changing set of images.” • Flickr and public image-sharing: distant closeness and • photo exhibition – Nancy A. Van House

  15. Social uses of digital imagery with a focus on smart phones applicability • LorantFarkas; SeveriUusitalo; Jan Blom • Problem: The user perceptions towards digital imagery are unknown. • Picture searching • Personal/public organization • Personal/public sharing • Goal: To propose proper design principles for imaging applications implemented on smart phones equipped with digital cameras.

  16. Hypothesis: The pervasiveness of smart phones. • Improvements to searching and sharing • Background: ? • The references are not referenced! • Approach: Patterns of existing applications. • How do users generally perceive digital • pictures? • User habits towards digital cameras • User habits/opinions towards sharing • Social uses of digital imagery with a focus on • smart phones applicability – LorantFarkas; SeveriUusitalo; Jan Blom

  17. Results: Digital photography behaviors. • Search behavior – browsing and clear-targeted • Personal vs. public • Further distribution • Control and awareness • Annotation of metadata • Manual vs. automatic • Content • Immediate vs. archived TUESDAY, NOV 18, 2008 • Social uses of digital imagery with a focus on • smart phones applicability – LorantFarkas; SeveriUusitalo; Jan Blom

  18. Design solutions: Opportunities. • Demand for metadata • User’s searching experience • Restrictive use of self-created content • Feedback mechanisms • Immediacy • Displaying content • Searching results • Archived content • “Business models enabling private providers to make money by sharing content and consumers making payments to download this material.” • Social uses of digital imagery with a focus on • smart phones applicability – LorantFarkas; SeveriUusitalo; Jan Blom
