Complete integration of GSR (galvanic skin response)
This version of Pro Lab comes with a GSR data filter and analysis tools, which enable researchers to reduce noise and detect peaks in their GSR data. This, together with the introduction of GSR-related metrics, completes the integration of the Shimmer3 GSR+ Unit in Pro Lab for screen-based and scene camera projects. You can design your study and record, visualize, analyze, and export GSR data, together with eye tracking data, in a single software solution.
The option to apply a GSR data filter allows for noise reduction. This smoothens the data and helps to remove the most common types of artefacts that can affect the GSR signal, such as high-frequency noise or sudden artefact changes. It also ensures proper event detection of Skin Conductance Responses (SCRs).
Visualization of skin conductance responses in Replay
SCRs are visualized in the GSR data chart in the Replay section of Pro Lab. This enables the qualitative analysis of participants’ emotional reactions related to known events expected to cause a reaction, such as visual attention to stimuli.
Export of GSR-related metrics
The GSR-related metrics that are being introduced in this version of Pro Lab include SCR count, event-related SCR amplitude, and GSR average. These metrics can be exported together with eye tracking and event metrics in one file for more in-depth analysis in third-party software.
Gaze trail in Replay
Gaze trail has been added in Replay, visualizing historical eye movement data and the applied gaze filter. This helps to understand and interpret behavior when performing the qualitative analysis of single recordings.
