     3== Executive Summary ==
     4''This report outlines a study into photo sharing.''
     5
     6''The study started with a literature review of related work and then went on to define core "concepts" in information sharing in general through knowledge elicitation techniques.''
     7
     8''Multiple task models were created based on the use of existing photo sharing systems and then combined into a single general task model. New tasks were defined which extended the task model to address issues which were identified in the knowledge elicitation process but are not supported by existing systems.  The extended tasks addressed user's needs through the use of emerging trends and technologies identified in the literature review.''

    8796An affinity diagram (Beyer & Holtzblatt, 1998) was used to collate all of the knowledge elicited from the critical decision and repertory grid methods and attempt to reveal common issues and themes. The diagram is built from the bottom up, allowing common structure and themes to emerge from individiual notes captured during interviews.

    92102Some significant and interesting themes emerge from the affinity diagram. Firstly, it reveals that as human beings we tend to share information more in socially significant times. That might be at a special social occasion or when something remarkable or unusual happens. Humans are also very good at predicting the emotional responses of others and judging what is and isn't a significant event.
     
    129139Alternative task sequences were identified from the task hierarchy and drawn onto a whiteboard, showing different possible paths through the hierarchy and conditions which apply.

    131 The next stage was to combine the two individual task models into a single generalised task model and the resulting hierarchy graph is shown in Fig. 2.1.

    136147The task model supports the findings of the knowledge elicitation techniques used earlier which indicated that humans like to store memories and share those memories using a high-tech solution and they are good at judging social situations. It does not reveal any privacy concerns which were suggested by these techniques. The task model also supports previous work which indicates the new opportunities being created by the proliferation of digital cameras, communication & commenting on the Internet, telling stories with and about photos, distributed collaboration and the use of metadata in the form of tagging.
