Game-based approaches are promising tools for enabling participation and collaboration in the expansion of renewable energy. The main advantage is that complex social-economical, technical or ecological interdependencies can be integrated as part of the game-logic to illustrate a broad range of impacts and synergies for different scenarios. Many of these approaches are paper-based although computers can support these decision-making processes by providing more comprehensive game logics, visualisations, calculations and real-time indicators (e. g., biodiversity measures, viewsheds, etc.). This article presents a computer-supported planning game for discussing the impacts of agrivoltaics (AV) at local level by collaborative development of different energy scenarios using a game-based approach. Results indicate that the provision of real-time indicators allow an objective discussion of different trade-offs. However, it is important for group work that the computer inputs do not interfere with the process, which is what we want to achieve with the development of a new human-machine interface.
