The aim of this user study is to evaluate the Elastic Windows approach experimentally and compare it with the independent overlapping windows approach in terms of supporting users in their tasks. The primary objective is to show that multi-window operations, provided by hierarchical window organization, in Elastic Windows outperforms the status quo independent overlapping windows approach in tasks dealing with multiple documents, source codes, etc. The user performance times on a range of tasks, analyzed by a number of statistical methods, are taken as a measure of achieving this objective.

The secondary objective is to identify usability problems of the Elastic Windows interface and examine some of the human factors issues. Post-study comments from subjects has been quite useful in revealing overlooked problems with an interface.
