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 prolong ed period s 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 sample s , for the field experiments at the three percentiles namely the 5 th , 50 th and 90 th 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 use d 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 factor s in designing car seats in this modern era and advance d technology age.
