LLMs-Assisted decision-making in sustainable contexts
Publication . Rodrigues, Ana; Cabral, Diogo; Campos, Pedro; Rodrigues, Ana Isabel; Pereira Campos, Pedro Filipe; Campos, Pedro
Promoting 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 thinking
Publication . Rodrigues, Ana; Cabral, Diogo; Campos, Pedro; Rodrigues, Ana Isabel; Pereira Campos, Pedro Filipe; Campos, Pedro
Inspired 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.
Maps between different kinds of two-level credibility-limited revision operators
Publication . Garapa, Marco; Fermé, Eduardo; Reis, Maurício D. L.; Garapa, Marco; Fermé, Eduardo; Reis, Maurício
Two-level credibility-limited revision
is a non-prioritized revision operation. When revising through a two-level credibility-limited revision, two levels of credibility and one level of incredibility are considered. When revising by a sentence at the highest level of credibility, the operator behaves like a standard revision, if the sentence is at the second level of credibility, the revision process results in a standard contraction by the negation of that sentence. If the sentence is not credible, then the original belief set remains unchanged. In this article, we introduce a novel constructive method for two-level credibility-limited revision operators, based on a modified version of entrenchment relations. Additionally, we propose a semantics for this type of operators, based on Grove’s systems of spheres. Furthermore, we present axiomatic characterizations for the newly proposed operators.
Tapest[o]ry: an interactive tapestry to raise awareness of marine noise pollution
Publication . Santos, Laura; Campos, Pedro; Dionisio, Mara; Quintal Santos, Laura Sofia; Pereira Campos, Pedro Filipe; Campos, Pedro; Dionisio, Mara
Through the years, the tapestry technique has been used for utilitarian purposes and
to tell stories. In our artwork, we took inspiration from this ancient craft and the
need to reconnect with our senses. This piece invites visitors to touch, feel, and
listen. Tapest[o]ry is a living tapestry that listens and responds with a narrative
representing the sea’s natural “murmurs” and harmful anthropogenic sounds.
The tapestry is turned into an interactive artwork by combining layers
of wool, crochet, and felt intertwined with hidden conductive threads.
Through storytelling and audience interaction, Tapest[o]ry hopes to
awaken empathy for the invisible chaos in our oceans and invite
reflection on how we, too, are part of this delicate rhythm.
DreamScape: fostering financial cognition through a serious game
Publication . Santos, Ana; Freitas, Constança; Bala, Paulo; Campos, Pedro F.; Dionisio, Mara; Bala, Paulo; Pereira Campos, Pedro Filipe; Campos, Pedro; Dionisio, Mara
Financial literacy is critical for economic empowerment, yet access
to effective financial education remains uneven. Serious games provide
an interactive and accessible approach to financial education,
fostering decision-making and cognitive development through im
mersive gameplay. In this demonstration, we present DreamScape,
a narrative-driven serious game designed to teach financial literacy
through interactive storytelling and puzzle-based mini-games. By
leveraging narrative immersion and problem-solving mechanics,
this online demo illustrates how interactive systems and creative
design can foster economic empowerment, contributing to a more
financially literate and equitable society.
