Keywords:Integrated assessment system, occupational health, ergonomics, joint angle, focus group
AbstractA good work posture is one of vital contributors to occupational health and to increase the efficiency of industrial workers. Recently, numerous research works have developed an Integrated RULA- KinectTM system for work posture assessment; however, usability of the developed system remains unknown. The objective of this study was to develop a prototype of Integrated RULA-KinectTM system. Additionally, this study performed usability testing on the Integrated RULA- KinectTM system and RULA Employee Assessment Worksheet to determine feedbacks and reactions from the potential users. A focus group session was conducted among eight potential users, which divided into 2 groups (novice and expert). The results of the focus group session revealed that both novice and expert users agreed that the Integrated RULA-KinectTM system is easy to use compared to RULA Employee Assessment Worksheet. This study concluded that the Integrated RULA-KinectTM system is able to counter some limitations of the RULA Employee Assessment Worksheet.
