Requirements Analysis for Tangible User Interfaces for Collaborative Use

On a requirements analysis process, software designers identify and collect information about users needs, requirements of the system and its user interface. In order to design user interfaces for collaborative use it is important to know what are functional requirements, individual and social users needs. This paper presents a process of requirements analysis for Tangible User Interfaces design, specifically for software that are used by a group of people working to achieve a common goal. The process followed to obtain requirements was based on Computer Support Cooperative Work perspective. As a case of study we considered the use of tangible medias in collaborative web design.
