Automated Matlab signal pipeline synchronizing EDA, EEG, and survey data

Design · All designs
Evidence · no claims cited

Description

The signal pipeline is an autonomous Matlab program into which raw signals from the Empatica E4, the CytonRK headsets, and Qualtrics survey data are fed, producing a synchronized and processed dataset without subjective human intervention. Each recording has an independent layered database so raw data or any processing step can be revisited, and a graphical interface allows visual inspection of each stage, including automated peak-alpha frequency identification.

Design Implications

Context

Requirements

  • Individual per-participant data files were needed because some steps, such as Fourier transforms into time slices, took nearly 10 hours to process

Constraints

  • Ledalab's conservative curve-matching approach may produce false negatives, so the research measured event amplitude rather than frequency

Target Learners

  • high school science students

Learning Goals

  • processing multimodal physiological and survey data for observational classroom research
