SLIDE 27IS246 - SPRING 2003 Discussion Questions Catherine Lai on “FotoFile” –FotoFile incorporates some automatic image analysis to help with annotations, for example, face recognition. But can we and how can we take more advantages of the context to determine appropriate situation for annotation? For example, if one picture is about a karaoke contest, there is a good chance that subsequent pictures taken within a three-hour span and close to the same location will describe the same event. –How is the use of narrative structure to help organize content so much different from annotating content manually? Does annotating contents mean to do data entry of predefined metadata like date and location as opposed to entering captions?

SLIDE 28IS246 - SPRING 2003 Discussion Questions David Warthen on “FotoFile” –In the short section on the “Use of Narrative Structure” the authors assert they can use the “narrative structure… as a source of their [photos] organization and annotation”, thereby turning annotation into a “more enjoyable” activity. However, they do not really explore this further. How might the system exploit this approach to capturing annotation? (e.g. from an actual narrative presentation) How might the system facilitate one of the envisioned usages, where “the storyteller shares groupings of photos and annotations over the internet”?

SLIDE 29IS246 - SPRING 2003 Discussion Questions David Warthen on “FotoFile” –The authors pay a great deal of attention to annotating personal photos, which they note requires significant effort. However, they do not attempt any cost/benefit analysis to see whether this effort pays off with reuse, or potential reuse, of the photos. If one considers the task from this point of view: How would one measure the ROI of investing in annotation? Might a “80/20” rule apply where it is only beneficial to invest in annotating the (loosely) 20% of pictures accessed 80% of the time? Might this imply introducing workflow annotation opportunities to the user upon first attempted re-use rather than upon entry in the system (beyond the basic “trip to Greece” or “Sam’s baby pictures” type of annotation)? Or, alternatively, would this present an insurmountable barrier to accessing the pictures for re-use at all?

SLIDE 30IS246 - SPRING 2003 Discussion Questions David Warthen on “FotoFile” –The authors have organized FotoFile to use scrapbook/photo album metaphors (enhanced with keyword retrieval and browsing). These metaphors have the benefit that consumers are familiar and comfortable with them, and root the use of FotoFile in the context of existing human activities. However, such metaphors can also be limiting. Let’s explore alternatives, including: Why separate limit FotoFile to pictures, video, and audio, rather than all data on the computer? These might include written documents, , contact lists, etc. Why limit FotoFile to the personal pictures on the computer, as opposed to tying them into online resources as well (encyclopedias, picture searches and picture archives, etc.)? What alternatives to scrapbook narrative presentation might be compelling? Perhaps a hyperlinked approach? Or a free-form associative approach?

SLIDE 31IS246 - SPRING 2003 Discussion Questions Lily Chen on “VideoMAP and VideoSpaceIcon” –Since the current version of VideoSpaceIcon cannot be simply applied when the camera operation is tracking or dollying, in which the camera position changes, I am very curious at how the "3D space model" the author defined for this approach will be constructed--how will they represent this 3D icon?

SLIDE 32IS246 - SPRING 2003 Discussion Questions Lisa Wang on “VideoMAP and VideoSpaceIcon” –How has spatial mapping of video advanced in the last ten years? –Has there been further research on three dimensional space modeling?
