The Shimmer3 GSR+ unit is a wearable GSR (galvanic skin response) sensor. It is designed to measure the conductance of the skin and integrated with Tobii Pro Lab to enable the combined use of eye tracking and GSR data in research easily and efficiently in one end-to-end solution.
The participant's live GSR data is displayed in Tobii Pro Lab's Record area and in the Moderator tool. This provides a way to set up and evaluate the GSR signal quality before the experiment starts and monitor it during the recording.
Tobii Pro Lab supports simultaneous recording and automatic synchronization of GSR and eye tracking data from our screen-based eye trackers, as well as the export of raw GSR data for analysis in third-party software.
GSR can indicate the level of emotional intensity of a person, varying with the arousal dimension of affect. It has been closely linked to autonomic emotional and cognitive processing and is widely used as a sensitive index of both emotional processing and sympathetic activity.
What we see makes us react and act. The combination of eye tracking and GSR enables researchers to get a more comprehensive understanding of human behavior and link visual attention with the level of arousal.
Psychology — the study of emotions, fear, and stress
Clinical research — the study of traumatic stress disorders
Media and ad testing — identification of the more engaging moments of a commercial
Usability — evaluation of task difficulty and confusion in web and software development
Shimmer3 GSR+ unit is a wireless sensor that monitors skin conductivity. It provides connections and preamplification for one channel of GSR data acquisition. The GSR+ unit measures the skin conductivity between two reusable electrodes attached to two fingers of the hand. Alternatively, the sensor is also compatible with disposable electrodes that can be attached to the palmar surface or any other part of the body.
Shimmer3 GSR+ also provides an additional channel that can capture the optical pulse or PPG (plethysmograph) signal to estimate the heart rate (not supported in Pro Lab yet). Designed to be wearable, the GSR+ unit is free from wired constraints and provides reliable data via a wireless transmitter. Reusable finger electrodes and wrist strap are included.
The GSR set also includes the Shimmer Dock which enables charging of a single GSR+ unit .
