BIOPAC provides software and hardware that allows research teams to study physiological measures, whether in this reality or in virtual reality, or for a single person or multi-person groups. Here are a few studies focusing on BIOPAC equipment’s ability to record physiological signals, including ECG, EDA, and Respiration.
Pairs Performing Under Pressure
How does acute stress affect real-time cooperation and competitive interaction between people? Pairs of women played a turn-based game while AcqKnowledge Software was acquiring and analyzing the dyad’s ECG signals to see when participants became stressed. Did they cooperate and play better when under acute stress?

A Pair, Inside & Out
People coordinate with one another to achieve joint goals, often spontaneously and without much conscious effort. However, in an interaction, do pairs coordinate their bodily rhythms as well? Using a BioNomadix unit to record Respiration, this study aimed to see whether dyads coordinated bodily rhythms through mutual adaptation (i.e., reciprocity) or by producing more predictable patterns.

Next-Gen Stress Reducer
Reducing stress is a well-proven way to reduce a person’s chance of becoming sick. By creating a relaxing virtual reality environment that people could enter, could they better manage their stress and feel better? A BIOPAC Data Acquisition System was used to record participants’ ECG, EDA, and RESP data while they were in the virtual world.
