Why the study?
Portable physiological devices facilitate data collection in interactive states, but the performance of the Empatica E4 wristband during naturalistic interactive conversations needed validation against an established device.
Does the Empatica E4 wristband provide reliable IBI, HRV, and EDA measurements compared to the MindWare device during rest and interactive conversation?

Supports E4 for resting IBI/HRV monitoring; leaves open EDA reliability in interactive settings.
Does the Empatica E4 wristband provide reliable IBI, HRV, and EDA measurements compared to the MindWare device during rest and interactive conversation?
The Empatica E4 wristband provides reliable IBI and HRV data, especially during rest, but fails to produce reliable EDA data during interactive conversational states.
