EDA Signal Dataset Collected During Startle Events While Walking With a Smart Cane

EDA Signal Dataset Collected During Startle Events While Walking With a Smart Cane Description This dataset includes Electrodermal Activity (EDA) signals collected from seven participants during an experiment in which they walked on a treadmill at a constant speed of 1 km/h while using a smart cane. During the walking task, participants were exposed to auditory startle stimuli designed to elicit stress responses. The smart cane was equipped with a Galvanic Skin Response (GSR) sensor integrated into its handle to continuously record physiological signals in a natural walking context. The data is organized by participant. All participants provided written informed consent both to take part in the experiment and to allow their anonymized data to be publicly shared for research purposes. Furthermore, the experiment was approved by the Ethical Committee of the Universidad de Málaga (reference 46-2024-H). Folder Structure Each folder corresponds to a particiapnt session (e.g., S0/, S2/, etc.) and contains the following files: S0/├── S0_DataExperiment.mat├── S0_audioEventVector.mat└── S0_SA_Score.mat ... S8/├── S8_DataExperiment.mat├── S8_audioEventVector.mat└── S8_SA_Score.mat In addition, the dataset includes a CSV file named caneFeatures_pre_post.csv, containing the extracted features from the GSR, tonic and phasic signals, allowing for the replication of the statistical analyses presented in the study. File Descriptions 1. S*_DataExperiment.mat Description: This file contains the EDA signals acquired at a 4 Hz sampling rate during the experiment, stored in MATLAB .mat format as a structured variable. Format: MATLAB Struct (3 fields) GSR: Contains the raw GSR signal along with associated time information: TimeStampDate (UTC date-time format) and TimeStampPosix (POSIX timestamp). TONIC: Contains the tonic component of the EDA signal with the same timestamp fields. PHASIC: Contains the phasic component of the EDA signal with the corresponding timestamps. 2. S*_audioEventVector.mat Description: This file contains information about the timing of the auditory startle stimuli presented during the experiment. The data is stored as a MATLAB struct sampled at 32 Hz. Format: MATLAB Struct (3 fields) data: A binary step signal indicating the presence of auditory events (0 = no stimulus, 1 = stimulus being played). TimeStampDate: A vector of timestamps in MATLAB datetime format, corresponding to each sample in the data field. 3. S*_SA_Score.mat Description: This file contains the self-reported State Anxiety (STAI-State) scores provided by each participant before and after the experimental session. The data is stored as a MATLAB struct. Format: MATLAB Struct (2 fields) Training: Numeric score reported after the training session. Experiment: Numeric score reported after the experimental session.
