Long-term perspectives of stakeholders’ perceptions of visualisation media in participatory planning : the case of Sanguan Temple Square in Guangzhou

Despite recent developments in the field of visualisation technology and evaluation studies, little research has been carried out on how stakeholders perceive different visualisation tools over the longitudinal development of planning projects. Using questionnaires and semi-structured interviews, this study examines the effectiveness of analog tools (sticky notes, photographs, paper maps, 3D physical models), digital visualisations (2D digital images, 3D modelling) and news coverage throughout a community micro-regeneration process. 3D physical models and 3D modelling were considered the most useful in terms of aiding comprehension and discussion. The longitudinal impacts of different visualisations were observed, ranging from information and communication to social, cultural and political influences on public awareness, cultural rehabilitation and political attitudes. The findings suggest using a combination of analog and digital visualisations overall suits stakeholders’ needs best.
