Physiological Data Acquisition for Deeper Insights into Prototyping
MetadataShow full item record
Based on the work of  a confirmatory study was conducted and two additional questions were investigated: How does iterating ideas affect the stress level of the participants while explaining their final design? And; Does the workspace setup influence the activity level of the participant while designing a prototype? The answers were found with the help of physiological data acquisition (electrocardiogram and acceleration). Our results confirm the previously conducted study. The data also suggests that the stress level during the interview is affected: Participants who were able to test their designs show in average a decreasing stress level, compared to participants who were not allowed to test where an increase thereof can be observed. Furthermore, the results show that the workspace setup influences the activity level of the participant.
