Electrophysiological assessment of cushions as attachment objects

Purpose: This study aimed to investigate the effects a cushion has on electrophysiological signals and to identify the important design elements required for manufacturing better therapy cushions. Design/methodology/approach: Four types of attachment cushions were manufactured by changing the shell fiber (cotton or microfiber) and the interlining (synthetic loose fiber or buckwheat). The products were evaluated by 20 healthy individuals (10 stable cushions and 10 unstable cushions). We examined the participants by electroencephalography (EEG) and electrocardiography (ECG). Findings: The authors found significant differences in both EEG and ECG between participants with unstable and stable attachment types. Originality/value: A complex approach to emotional product evaluation was attempted by analyzing differences due to design variables of cushions through subjective evaluation as well as EEG and ECG.
