The overall architecture of the environment is to include (a) Project Spaces for professional and public users, (b) a Co-design and Communication Interface between the project spaces, and (c) a Data Platform providing complex data integration and analytics. The environment will harvest and exchange ideas and comments from large public audiences and professional experts alike. It provides modelling and visualization tools to support co-creation and understanding of design concepts especially during the critical early stage of the project life cycle. It thus enables intuitive understanding of complex design issues and constructive feedback. For this new generation collaborative digital environment, a co-design methodology will be created as well as validated technology, including software and human-machine interfaces, communication protocols and data management.
The specific objectives are:
- To design and develop a new Public Project Space ("Project Playground") where intuitive and gen-erative HMI support citizen's understanding of complex urban design issues, and enable them to con-tribute creative design ideas;
- To design and develop a new Co-design and Communication Interface ("Co-Design Space") which connects the public "Project Play Ground" to professional studios of experts e.g. urban designers, ar-chitects, and developers, and functions as unidirectional exchange for design ideas and comments es-pecially in the crucial early phase of the design and development process;
- To design and develop a Central Data Platform ("Data Space") where information of ongoing pro-jects will be pooled, integrated, and analysed. In the Data Space, highly heterogeneous data are pro-cessed into comprehensive Project Information Models (PIM), from which Moderated Models (MoM) can be derived and displayed to respective users in their project spaces.
From user perspective, U_CODE offers three so-called Project Spaces in which each stakeholder and user group can engage in its own way with urban planning work: (1) Professional Designers´ Pro-ject Space, (2) Public Project Space, and (3) Project Space for the co-design of Professional and Public. The differ-ent spaces are linked to U_CODE´s data bank and information platform (Data Space), from which they are served data analytics and services, e.g. public sentiment analysis from social media. The conception of digital project spaces for the co-designing of professionals and citizen experts, as well as for the co-designing of citizens among themselves, are the very design and development tasks within the project.
