摘要
In this paper, we study how different mental stress levels are distributed in a conceptual design process. Firstly, we reviewed a Stroop Test experiment conducted earlier in our lab to confirm the use of heart rate variability (HRV) as a reliable index of mental stress. Secondly, we reported our experiment on seven designers; HRV data and body movements were recorded along with design processes. Design data was segmented and HRV parameter as indicator of mental stress was computed for each segment. Then the mental stresses were classified into seven levels. The result showed that most of the activities in a design process were performed at low levels of mental stress. The design activities reduce as the level of mental stress increases. No correlation was found between types of design activities and mental stress.
