New Computer Programming Study Findings Have Been Reported by C. Pontonnier and Colleagues (Assessing the Ability of a VR-Based Assembly Task Simulation to Evaluate Physical Risk Factors)
By a News Reporter-Staff News Editor at Computer Weekly News -- Current study results on Computer Programming have been published. According to news reporting from Rennes, France, by VerticalNews journalists, research stated, "Nowadays the process of workstation design tends to include assessment steps in a virtual environment (VE) to evaluate the ergonomic features. These approaches are cost-effective and convenient since working directly on the digital mock-up in a VE is preferable to constructing a real physical mock-up in a real environment (RE)."
The news correspondents obtained a quote from the research, "This study aimed at understanding the ability of a VR-based assembly tasks simulator to evaluate physical risk factors in ergonomics. Sixteen subjects performed simplified assembly tasks in RE and VE. Motion of the upper body and five muscle electromyographic activities were recorded to compute normalized and averaged objective indicators of discomfort, that is, rapid upper limb assessment score, averaged muscle activations, and total task time. Rated perceived exertion (RPE) and a questionnaire were used as subjective indicators of discomfort. The timing regime and complexity of the assembly tasks were investigated as within-subject factors. The results revealed significant differences between measured indicators in RE and VE. While objective measures indicated lower activity and exposure in VE, the subjects experienced more discomfort than in RE. Fairly good correlation levels were found between RE and VE for six of the objective indicators. This study clearly demonstrates that ergonomic studies of assembly tasks using VR are still challenging. Indeed, objective and subjective measurements of discomfort that are usually used in ergonomics to minimize the risks of work-related musculoskeletal disorders development exhibit opposite trends in RE and VE."
According to the news reporters, the research concluded: "Nevertheless, the high level of correlation found during this study indicates that the VR-based simulator can be used for such assessments."
