DesignTrace: Exploring, Iterating and Tracking Design Alternatives with GenAI

Creativity support tools have begun to incorporate GenAI for exploring ideas. However, our preliminary study with nine designers showed that current GenAI tools lack explicit support for iteratively evolving, reflecting upon and tracking design alternatives. We developed DesignTrace, an early-stage GenAI design tool t…

"Should I choose a smaller model?'': Understanding ML Model Selection and Its Impact on Sustainability

The increasing accessibility of large machine learning (ML) models has resulted in their widespread adoption in everyday products, with a correspondingly negative environmental impact. Selecting more suitable ML models could not only improve training time and achievable accuracy, but also long-term sustainability. How…

FusAIn: Composing Generative AI Visual Prompts Using Pen-based Interaction

Although current generative AI (GenAI) enables designers to create novel images, its focus on text-based and whole-image interaction limits expressive engagement with visual materials. Based on the design concept of deconstruction and reconstruction of digital visual attributes for visual prompts, we present FusAIn, a…

When Should I Lead or Follow: Understanding Initiative Levels in Human-AI Collaborative Gameplay

Dynamics in Human-AI interaction should lead to more satisfying and engaging collaboration. Key open questions are how to design such interactions and the role personal goals and expectations play. We developed three AI partners of varying initiative (leader, follower, shifting) in a collaborative game called Geometry…

DesignPrompt: Using Multimodal Interaction for Design Exploration with Generative AI

Visually oriented designers often struggle to create effective generative AI (GenAI) prompts. A preliminary study identified specific issues in composing and fine-tuning prompts, as well as needs in accurately translating intentions into rich input. We developed DesignPrompt, a moodboard tool that lets designers combi…

ImageSense: An Intelligent Collaborative Ideation Tool to Support Diverse Human-Computer Partnerships

Professional designers create mood boards to explore, visualize, and communicate hard-to-express ideas. We present ImageSense, an intelligent, collaborative ideation tool that combines individual and shared work spaces, as well as collaboration with multiple forms of intelligent agents. In the collection phase, ImageS…

SemanticCollage: Enriching Digital Mood Board Design with Semantic Labels

Designers create inspirational mood boards to express their design ideas visually, through collages of images and text. They find appropriate images and reflect on them as they explore emergent design concepts. After presenting the results of a participatory design workshop and a survey of professional designers, we…

May AI? Design Ideation with Cooperative Contextual Bandits

Design ideation is a prime creative activity in design. However, it is challenging to support computationally due to its quickly evolving and exploratory nature. The paper presents cooperative contextual bandits (CCB) as a machine-learning method for interactive ideation support. A CCB can learn to propose domain-rele…
