Mobile brain/body imaging (MoBI) for the study of the human improvisational creative process. In the spirit of the "Exquisite Corpse," an improvisational creative game, three artists created three art-pieces. The artists were equipped with 64 channel wireless EEG (2 channel EOG) and 3 inertial measurement units on forearms and head. We report the most relevant features for offline classification both in motion and EEG data pertaining to baseline, planning, and execution phases, of the improvisational creative process. The angular velocity in the left-right direction and the magnitude ratio (right / left hand) of the movement jerk were features that consistently shared the most mutual information with the class labels. The most relevant features for classification in the EEG data varied for each artist, and relate to their approach to the artwork. These features were mostly found in the parietal, central and frontal electrodes across frequency bands and time-domain features.
