Dataset for Motion Artifact Removal in GSR Signals from Smart Cane

Dataset for Motion Artifact Removal in GSR Signals from Smart Cane This dataset accompanies the publication: Villalba-Bravo, R., Trujillo-León, A., & Vidal-Verdú, F.Adaptive Filter to Remove Motion Artifacts from GSR Sensor Embedded on Handle CaneIEEE SENSORS 2024, Kobe, Japan, pp. 1–4.DOI: 10.1109/SENSORS60989.2024.10784798 Description This dataset includes Galvanic Skin Response (GSR) signals recorded in an experiment involving a single participant walking on a treadmill while using a smart cane. The cane was equipped with both a galvanic skin response (GSR) sensor and a force-sensing resistor (FSR) . Motion artifacts caused by walking were recorded and filtered using an adaptive Notch filter whose center frequency was dynamically adjusted based on the FSR signal. The dataset contains 4 sessions, each stored in its own folder. Folder Structure Each folder corresponds to a measurement session (e.g., Session_01/, Session_02/, etc.) and contains the following files: Session_1/├── cane_FSR.txt├── noisy_cane_GSR.txt├── filtered_cane_GSR.txt└── ref_GSR.txt ... Session_4/├── cane_FSR.txt├── noisy_cane_GSR.txt├── filtered_cane_GSR.txt└── ref_GSR.txt File Descriptions 1. ref_GSR.txt Source: Stationary reference sensor Description: Clean GSR signal used as ground truth for motion-free skin conductance. Format: CSV (2 columns, no headers) timestamp: Unix timestamp (e.g., 1718353970.03125) gsr_value: Reference GSR signal (artifact-free) 2. noisy_cane_GSR.txt Source: GSR sensor embedded on the smart cane Description: GSR signal contaminated by motion artifacts during walking. Format: CSV (2 columns, no headers) timestamp: Unix timestamp gsr_value: Noisy GSR signal 3. cane_FSR.txt Source: Force-sensing resistor (FSR) under GSR sensor Description: Pressure data from the cane's handle, used to detect steps and model motion artifacts. Format: CSV (2 columns, no headers) timestamp: Unix timestamp fsr_value: Force signal amplitude 4. filtered_cane_GSR.txt Source: Filtered output from adaptive Notch filter Description: GSR signal from the cane after motion artifact removal. Format: CSV (2 columns, no headers) timestamp: Unix timestamp gsr_value: Filtered GSR signal Data Format and Notes All time values are recorded in Unix POSIX format with fractional seconds.
