Smartphone-based Ergonomic Risk Assessment

Current field ergonomic risk assessments are based on observational methods. These methods are time-consuming, labor intensive and error prone because they often require subjective judgements for interpreting risk factors. To address these issues, the presenter Dr. SangHyun Lee has developed a smartphone-based automated risk assessment system, which only requires video images of workers taken by ordinary digital video recording devices such as smartphones without any sensor/marker/suit attached. The goal of the system is to expedite the current ergonomic risk assessment process by automating quantifications of posture information.
