Having finished implementing LastHistory we wanted to find out how well our considerations had worked and if people would actually find it useful.

1. Problem Setting

…

So, there are large data pools…How are ideas currently visualized?

So much for the data space and its attributes. Next, we have to think about who our users are and what they want to do. All lifelogging applications are first of all about

2. UserRequirements

Questions, an Idea Visualization should be able to answer

(1) How many ideas are in the idea pool? (2) Who are the most active users? (3) Which ideas have been most commented? (4) Which ideas are similar? (5) Which topics/tags do ideas belong to? (6) Are there groups of related ideas (which could be combined)? (7) Are there relationships between ideas (other than tags)? (8) How have idea submissions/comments developed over time?

Summary of requirements based on expert interviews

Generic / non functional requirements

Domain specific / functional requirements

expressivity effectiveness good usage of space scalability performance

R1 display all attributes of an ideaR2 sort ideas by different attributesR3 filter by attributes to allow data reductionR4 contrast the relationship of attributesR5 explore development over timeR6 explore relationship between ideasR7 edit ideas within the visualizationR8 partial loading/displaying of large idea pools

(not implemented)

3. IdeaViz

4. Initial Validationand Future Work

Would you tell me, please, which way I ought to go from here?
