AI feedback system · 4 test conditions
I designed all four conditions myself.
View on GitHub ↗Designers now treat generative AI as a creative partner, not just an image library. Most studies compare how good the AI's output is; fewer look at how its feedback changes the way a designer thinks.
Should AI feedback read the designer's sketch or only the task, and should it come back as text or as an image?
Writes feedback on the idea as it changes, using the users and needs the participant set.

48 students from five universities took part, each in one condition; 42 gave valid data. They had 20 minutes to sketch a chair for a long-term care center, asking the AI for feedback after every sketch, then filled in a questionnaire and joined a short interview.
Image feedback reliably helped people produce more ideas. Variety depended on the pairing: images worked best with Sketch-based feedback, text with Task-based. Easy-to-follow Task-based suggestions made people feel more supported. No single mode won on every measure, so how the AI gives feedback matters as much as what it generates.

Turn the question into comparable conditions.
The study needed more than one AI-feedback mode, so the condition structure became part of the product design.
