In architecture, physical models, either for study and initial analysis of the project either for exhibition, where a more definitive model is used to present the characteristics of the final project, play a key role as a tool in the creative process of the architect and the planning and design of projects. However there are always some difficulties associated with it such as the time spent and the costs involved in their production and modification whenever it is necessary to predict the outcome of changes in the project or viewing details of the interior of the model, which may not be feasible.Aiming to assist architects to overcome the difficulties encountered in the current process of design in architecture, Microsoft Language Development Center in collaboration with the Department of Architecture and Urban Planning of Instituto Universitário de Lisboa (ISCTE-IUL) launched a hypothesis for solving the problem consisting in the use of visualization and interaction technology in augmented reality with 3D virtual model of the architecture project, on same scale of the study model, through a tablet-type device.The hypothesis verification went by creating a prototype allowing the display of virtual information, like 3D virtual models of buildings and their environment using augmented reality. This system allows these models to be viewed through a tablet using vision techniques based on texture tracking, which needs a visual brand planar (an image) reference, that works as a plan for registration and positioning of the model. The system also allows several features that facilitate either the modifying of the 3D model either the interaction with it, such as occlusion of objects and the support of interactive cutting planes for interior detail, widely used in architecture. To enrich the viewing experience and interact with the 3D model, the system will use a mobile computing platform with touch screen, allowing for touch-based interaction.
