The Good, the Bad, and the AHA! Blends

We present and discuss quality assessment of visual blends based on how humans perceive them. This work represents part of a wider study aimed at determining the fundamental characteristics of a good blend. Based on the obtained insights, we hope to make a more comprehensible explanation of some less clear and not fully described aspects of the conceptual blending mechanism that play a fundamental role in creative thinking. Additionally, we intend to bring these insights into the design of artificial creative systems.
