AI-Augmented Design Tools for Surfacing and Developing Design Reasoning

My research focuses on how digital fabrication and CAD tools can support the development of design reasoning—helping learners understand, articulate, and reflect on the decisions behind their modeling workflows. I design AI-enhanced, agentic tools that surface decision moments, externalize reasoning, and enable reflection through comparisons and previews. Broadly, my work explores how AI can augment, rather than replace, human agency and expertise in design.

Designers of physical objects make assumptions on the material and fabrication workflow early in the design process. Recovering from bad assumptions is hard, because the design and resulting CAD model are locked-in to those assumptions. We present CAMeleon, a software tool to interactively explore fabrication workflows at any stage of the CAD process.

OriStitch is a computational fabrication workflow to turn existing flat fabrics into self-folding 3D structures. It uses machine embroidering of functional threads in specific patterns on fabrics, users then apply heat to deform the structure into a target 3D structure. OriStitch is compatible with a range of existing materials (e.g., leather, woven fabric, and denim).

We present Y-AR, a Computer Aided Design (CAD) interface for 3D wire bending. Y-AR uses mixed reality to let designers create structures that physically connect to objects in the environment. The interface incorporates springs as design primitives which (1) apply forces to hold objects, and (2) counter-act dimensional inaccuracies inherently caused by mid air modeling and measurement errors in AR.

Multi-Self” is a BCI-VR tool designed to enhance metacognitive monitoring in architectural design by providing real-time, visual biofeedback on emotional responses. In a pilot study with 24 participants, the tool was found to encourage design exploration, foster self-awareness, and help modulate uncertainty, though feedback accuracy received mixed responses.

The Emotive Room project explores how interactive technologies can modulate users' emotional states through real-time brain-computer interfaces. By adjusting the color and form of interior spaces in response to users' stress levels, the design aims to promote calmness or boost energy as needed. This approach opens new pathways for enhancing well-being in built environments.
