Reaction: A Review of Overview+Detail, Zooming, and Focus+Context Interfaces

The paper is a very descriptive. It has a detailed survey of techniques used in Overview+Detail, Zooming, and Focus+Context Interfaces. The paper has rich examples with diagrams. It does a good job in bringing out the different ways the basic visualization tasks are implemented. It talks about how these tasks can be implemented and what are some of the practices that work. It provides reasoning for techniques that work using granular tasks and also cognitive loads. Unlike many other papers this survey evaluates the examples against the verified results in the field. The Mac OS dock fish eye example is interesting. The discussion on google maps gives some idea about zooming and how it needs to be really good or it might hinder the over all use of the application itself.

The paper has been summarized very well. It first enlists all the approaches and describes them in simple terms. It also points out that there is no ideal way of building a visualization and approaches and tasks to be used depend on the objective the visualization.
