MSc thesis topic: Virtual Reality for Urban Climate Communication
Virtual Reality (VR) offers novel opportunities to communicate environmental information, to realise place-based education and allow for grounded decision making. Geo-spatial scientists embrace these opportunities as their domain is inherently spatial and therefore offers existing tools to create content for virtual experiences such as geographic information systems. At the same time, VR allows for experiencing not just the present state of an environment but also its past or its future, this is essential for making well-informed planning decisions. Furthermore, VR also allows for exploring what-if scenarios and advancing solutions to challenging problems through a discovery-based approach.
In this MGI project, the focus is on urban climate and in particular wind.
Climate effects in urban environments like temperature, wind or radiation have a perceptual impact on human comfort in open spaces. They substantially influence the experience and use of urban spaces (Lenzholzer, 2015) and are therefore a strong design criterion for outdoor thermal comfort, i.e. turbulent urban wind in some areas like: Downwash/ Downdraft Effect, Wake effect, Venturi Effect, Height – Speed Effect, Downwind Eddy and Counter- Current effect. The need to adapt certain urban areas to climate conditions is well known, decisionmaker like politicians or civilians, next to professionals in urban design fields, are not aware about urban climate adaption strategies (Lenzholzer et al., 2020). To raise awareness about urban climate conditions Lenzholzer et al. call for “effective methods” like “exhibitions, games or workshops” which educate citizens and politician’s through “easily understandable information” (Lenzholzer et al., 2020).
Representations of UC i.e. urban wind (UW) in architecture, engineering, and urban design projects are mainly visual ones, like maps, graphs, symbols, suggestive sketches, translating wind behaviour with arrows (Lambert et al., 2014) or wind simulations, which show analysed wind flow behaviour in an (urban) environment based on CFD Models. Educating about UC, as a visual representation can provide a ‘’fast’’ understanding of complex and heterogeneous data (Tufte, 1997) therefore visual representations play a significant role in communication. In case of UC, visual representations can reveal invisible information or show indicators of UC (Belgacem et al., 2018, Masson, 2000).
New technologies like Virtual Reality (VR) with Head Mounted Displays (HMD) create opportunities to improve education and, in this way, the learning outcome. VR & HMDs can enrich educational environments to visualize complex structures and provide assessment and timely feedback, but VR is still in its formative years regarding how it can be used, and, how it can be designed in an educational context.
To examine if VR with HMD are more effective learning tools than classic multimedia a comparsion study is needed.
