Digital war room for design

In this paper, we describe the requirements elicitation for a digital war room --- a group work facility to support people interacting with digital (and analog) materials. The target user group is product design teams and construction engineers/architects. Main requirements for an interactive group work space include fluent sharing of documents within the facility and ability to comment on them, support for both analog and digital sketching and writing by hand, minimum of three displays allowing parallel tasks and comparison of different alternatives and the importance of the physical properties of the facility.
