Specification of an interactive system will describe and conceptualize: a multi-users 4D CAD interaction system, using recent touch-based technologies, e.g. a
touch-based tabletop device, for taking into account time in the early stage of architectural
This system will be prototyped.
It will be a “tangible” result, which will be potentially transferred to construction practitioners after the project. Specifications will also deal with BIM-based information system functionalities.
