The aim of this study is to evaluate the Elastic Windows approach analytically and compare it with other information management systems. The primary benefit of an analytical study is to make comparisons across a number of systems without any of the costs associated with user studies (e.g. subject cost and time, experiment design, etc.). Analytical studies also yield relatively concise measures which can be used by designers to improve interfaces by seeking to increase measures.
A number of metrics and factors are determined that significantly influence the effective and efficient use of information management interfaces. In order to develop metrics, a general model of information management interfaces is proposed based on the information presentation hierarchy. Using this model, metrics are determined from the perspectives of organization, access and manipulation of information in regards to both static and dynamic aspects of interfaces.
