Ergonomic Risks on Driver’s Posture Interface

Abstract

This research paper presents a study and analysis on the existence of ergonomic risks to drivers while sitting in the vehicle seat for prolonged periods in static posture during driving of a vehicle. The main aim of this research article is to understand and prove the hypothesis on the existence of ergonomic risks of drivers in the sitting static posture in the vehicle. The vehicle in the study here is a car. Test subjects are samples, for the field experiments at the three percentiles namely the 5th, 50th and 90th percentile range of drivers in Singapore. The demographic parameters for the test subjects identified for the purpose of this research encompass the gender, age range and competency level. The dependent variable use for this research is “driver posture” whilst the independent variable used is the “ergonomic risks”. The research is important to understand the existence of ergonomic risks for awkward sitting postures in order for ergonomists and especially car manufacturers to take into consideration of ergonomic safety factors in designing car seats in this modern era and advanced technology age.
