6 CONCLUSION
This paper presents a co-creative design tool called
Collaborative Ideation Partner (CIP) that supports
idea generation for new designs with stimuli that vary
in similarity to the user’s design in two dimensions:
conceptual and visual similarity. The AI models for
measuring similarity in the CIP use deep learning
models as a latent space representation and similarity
metrics for comparison to the user’s sketch or design
concept. The interactive experience allows the user to
seek inspiration when desired. To study the impact of
varying levels of visual and conceptual similar
stimuli, we performed an exploratory study with four
conditions for the AI inspiration: random, high visual
and conceptual similarity, high conceptual similarity
with low visual similarity, and high visual similarity
with low conceptual similarity. To evaluate the effect
of AI inspiration, we evaluated the ideation with CIP
using the metrics of novelty, variety, quality and
quantity of ideas. We found that conceptually similar
inspiration that does not have strong visual similarity
leads to more novelty, variety, and quantity during
ideation. We found that visually similar inspiration
that does not have strong conceptual similarity leads
to more quality ideas during ideation. Future AI-
based co-creativity can be more intentional by
contributing inspiration to improve novelty and
quality, the basic characteristics of creativity.
