Co-designing vacant lots using interactive 3D visualizations - Development and application of the Land.Info DSS.

[Display omitted] • Co-production and agile software development methods were used to create a video-game based DSS. • The DSS was developed and applied in workshops for the design of multifunctional open space. • Co-production with residents can result in improved processes and outcomes. • Residents required additional information to orient themselves in the DSS. • Realism and DSS ease of use contribute to dialogue during co-design sessions. Collaborative processes of co-production between end-users and designers can be an effective means to produce shared understanding about a system and has been shown to improve the quality of, and support for, design outcomes. In spatial design and planning, co-production usually involves engaging community members in the design and planning of their local environment (co-design). However, to support co-design of landscapes it has been recommended that decision support systems (DSS) be developed for both the specific decision setting, and in conjunction with meaningful public guidance and input, to transition professional practice to working with rather than for the public. The research presented here responds to these recommendations by developing and evaluating a process for involving end user residents in the co-production and application of the Land.Info DSS in the design of multifunctional landscapes within their communities. The research used participatory workshops incorporating a structured elicitation process, agile software development, and user evaluation to design and test a video game-based DSS in context of two real-world design settings in Detroit, MI, USA. In this paper, we describe and evaluate the process and outcomes, with the results showing improved evaluation over the course of development and overall positive outcomes from this type of collaboration. We also found that residents required additional information to orient themselves in the DSS. In addition, visualization realism and ease of use of the DSS contributing to dialogue during co-design sessions. The paper ends with recommendations for future development and research.
