Objective The objective was to determine the effect of two head-mounted display (HMD) augmented reality (AR) devices on muscle activity and eye strain of electric utility workers. The AR devices were the Microsoft HoloLens and RealWear HMT-1. Backgro

More than ever, human factors engineers and ergonomists need to justify our practice’s value to management. How can we effectively communicate with management? How should we present a Return on Investment (ROI) that leadership will find useful that

The design of the structures that workers use to enter and exit utility trucks can affect the safety of workers. Workers can access the truck via the cab or via the truck bed on the side or rear. Large vehicles, such as aerial trucks in a utility fle

The purpose of this study was to evaluate the maximum grip force a user can exert on a motorcycle clutch. In a laboratory setting subjects (57 male; 34 female, 95% right-handed) were asked to exert maximum grip strength using their left hand on an ac
