Optimized Pressure Sensor Dataset for Driving Posture Recognition (DPR)

Dataset Overview

This dataset provides a comprehensive collection of 172,000 pressure maps (64×160 sensors) recorded from 30 participants assuming 20 distinct driving postures. The dataset was developed to enhance Driving Posture Recognition (DPR) using pressure sensor arrays, offering a privacy-preserving, cost-effective, and accurate alternative to camera-based monitoring systems.

This dataset enables sensor array optimization for real-world applications in automated vehicles, driver safety, and ergonomic research by leveraging Machine Learning and Deep Learning techniques.

Key Features

• Participants: 30 healthy adults with different anthropometric characteristics (BMI, height, weight).
• Acquisition Conditions: Laboratory setup with driving simulator.
• Devices: XSENSOR X3 PRO pressure sensor array, ensuring high accuracy (±10%) and fine spatial resolution.
• Data: 172,000 labeled pressure maps (64×160 sensors) across 20 postures.
• Data types: Raw CSV & PNG formats for both direct analysis and visualization.

Data Collection Methodology

1. Participants were introduced to the setup and guided through familiarization with the seat.
2. The operator instructed the participant on the posture to mimic during data collection.
3. The participant and the operator simultaneously pressed four highlighted points on the matrix before assuming each posture.
4. Each session lasted approximately 8 minutes per participant. Pressure maps were saved as ‘CSV’ files. A MATLAB script was used to generate grayscale images from the data.
