Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
The measure of a design problem s hardness is a window into human intelligence. We propose a new measure of problem hardness based on the transient microstate percentage of EEG signals. Based on the heuristic that different segments of design protocol data have different perceived hardness, we use this transient microstate percentage to segment design protocol data into domain-valid segments. Currently, two main techniques exist to analyze design protocol data: simultaneous thinking aloud and retrospective protocol analysis. Our method based on physiological measurements (EEG) mitigates the strengths and weaknesses of both methods. It was able to classify some segments as expected and discover new segments. Using EEG to solve this problem is a typical inverse problem where a thought process is reconstructed from potential-valued signals of the brain. We discuss limitations and challenges of such an approach.
