Reaction : A review of overview+ detail, zooming, and focus+ context interfaces

One interesting thing about Overview+detail is that several applications allow thumbnails sizes to be changed according to the viewer’s choice. This reduces trade-offs between time to access data and visual clarity. But most users are unaware of such features in an application. It was also evident that use of lenses is more suitable towards application such as "draw" and less suitable to text viewing applications.

We see several practical issues mentioned in the paper in our day to day lives. For example, the paper mentions that users are unaware of how to zoom (using mouse click) or how to reverse it. In an IPod map view, a single finger tap zooms in and a double finger tap zooms out. People generally know how to zoom in but not how to zoom out.

Further, Focus+context techniques in source code navigation have really made the lives of programmers easy!
