Overview

Validation study demonstrates moderate-to-excellent accuracy of a smartphone-based posture tracking system, suggesting potential for low-cost real-time ergonomic risk monitoring on construction sites.

Key Points

  • To develop and validate Ergo-PAS, an Android smartphone-based posture analysis prototype that monitors postures and provides real-time alerts for ergonomic risks in construction.
  • Mounted synchronized Android smartphones containing inertial measurement units on the trunk, upper arm, and forearm of participants (N=5) during controlled posture tasks.
  • Assessed posture detection accuracy against a reference optical Vicon motion capture system using Pearson's correlation, intraclass correlation coefficients, and linear regression calibration.
  • Ergo-PAS exhibited moderate-to-excellent validity versus motion capture, with Pearson's correlation ranging from 0.13–0.99 for trunk flexion, 0.50–0.95 for upper-arm elevation, and 0.57–0.94 for forearm movements.
  • Reliability varied across body segments with intraclass correlation coefficients spanning 0.08–0.99, while linear regression revealed stable slopes across participants alongside joint-specific intercept differences.
