Representation types and visualization modalities in co-design apps

This paper’s primary goal is to analyze representation types and visualization modalities of web-based and mobile applications for collaborative processes in urban planning. To this end, a comparative study of several case studies, based on literature review, analysis of EU projects’ websites, academic/commercial websites, web-platforms, application Platforms as a Service (aPaaS), Software as a Service (SaaS) dealing with co-design for urban design and planning purposes, has been done. We analyzed 56 commercial and non-commercial apps active from 2010 to 2020 across different countries. Despite the increasing level of innovation and commercialization of Augmented/Virtual Reality solutions and immersive visualization devices in the last few years, the emerging framework of ICT solutions for participatory processes in the urban planning field is still characterized by bidimensional representations and non-immersive visualizations modalities
