A method for specification of collaborative interfaces through the use of scenarios

The complexity and the extension of tasks in the world today demand an extensive interaction among people with different knowledge backgrounds, who need to work in cooperation, aiming at a common goal. We present a method to model the tasks and actions that a group of users carries out when working cooperatively through a computational system interface. For this purpose, we use scenarios for requirements gathering for user-cooperative interfaces. Along with the method, we propose the use of a notation that was developed to support interaction characteristics of users in cooperative work.
