- LLMs-Assisted decision-making in sustainable contextsPublication . Rodrigues, Ana; Cabral, Diogo; Campos, Pedro; Rodrigues, Ana Isabel; Pereira Campos, Pedro Filipe; Campos, PedroPromoting sustainability through creative approaches offers a path way to achieving sustainability goals, yet the resulting solutions often lack efficiency and effectiveness. Addressing this challenge, we introduce SAIESE, a Creativity Support Tool (CST) leveraging a Large Language Model (LLM) to support the creative process, the generation, evaluation, and selection of sustainable ideas. Our work articulates LLMs role in exploration and selection, focusing on sustainable ideas based on three metrics- Environmental Impact, Economic Benefits, and Social Effects. Our evaluation demonstrates that the prototype outperforms human evaluative tasks in usability, creative thinking, and decision-making while reducing cognitive workload. However, its effectiveness in promoting creativity de pends on the clarity of ideas, underlining the importance of hu man collaboration in ambiguous contexts. This work articulates the potential of AI in creativity, expanding current research on CSTs by highlighting sustainability-oriented creative processes and decision-making support.
- Inside the solution diamond: the role of CSTs supporting divergent and convergent thinkingPublication . Rodrigues, Ana; Cabral, Diogo; Campos, Pedro; Rodrigues, Ana Isabel; Pereira Campos, Pedro Filipe; Campos, PedroInspired by the growing development of Creativity Support Tools (CSTs) to enhance creative work over the past ten years, we in vestigate the evolution of these tools in supporting divergent and convergent thinking based on the Double Diamond model. How ever, the approaches developed so far do not represent the complete design space, indicating the existence of a limitation during the creative process. This article presents the Divergent-Convergent Thinking Framework (DCTF) to support an understanding of the composition of the creative spectrum. Based on a literature review (N=96), our framework synthesizes key categories of creativity and, particularly, research on CSTs. We propose six dimensions and four challenges and opportunities to guide the analysis of already developed CSTs, the development of future CSTs, and how to inte grate them into users’ workflow. To test its relevance, we present a possible scenario for the framework’s applicability in the context of sustainable design-oriented creativity. We demonstrate how the framework guides the selection of ideas, supporting the cyclical transition between divergent and convergent thinking.
