Abstract

Understanding team dynamics and their physiological impact is essential across high-stakes industries such as healthcare, aviation, and defense. In stressful environments, optimizing team performance requires not only assessing communication but also monitoring physiological indicators of stress. Electrodermal activity (EDA) and heart rate variability (HRV) are commonly used to capture autonomic responses, offering insight into emotional arousal and cardiovascular regulation.

This pilot study compares a commercial wearable device, the EmbracePlus, with a research-grade device, the Shimmer3 GSR+, to evaluate differences in physiological signal acquisition. Twelve participants completed a five-phase experimental protocol while wearing both devices simultaneously on the non-dominant wrist/forearm. EDA was analyzed by examining the tonic and phasic signal components, and photoplethysmography (PPG) was processed to assess signal quality and HRV. This comparison contributes to the broader effort of validating emerging wearable technologies for research applications.
