Reaction: Toward a Deeper Understanding of the Role of Interaction in Information Visualization

The author of this paper has emphasized on a very good point i.e the interaction aspect of information visualization has been overshadowed by the representational aspect.Moreover, representation and interaction both go hand in hand for a successful information visualization. One is incomplete without the other. There still is tremendous amount of scope for research in interaction aspect of information visualization. This paper is an attempt to encourage more research this field.The various interaction techniques have been effectively described.

After tremendous amount of research the authors have classified interaction techniques in seven categories. The content is extremely informative and each of these categories have been explained thoroughly with good illustrations. However, the interaction techniques might straddle between two categories. It is not always possible to classify a particular technique under one category. Interaction is an important aspect of visualization. In order to achieve success, the user intent should be given more weight. In other words, the focus should be on the user intent rather than how a particular technique provided by Info Viz. works.
