Research On Human Factors Design Of Virtual Reality Headset Combining SEMG And Pressure

With the growth of the virtual reality industry,more and more virtual reality products are becoming visible to the public.However,prolonged use of these products will result in a number of ergonomic issues,which will have a negative impact on users’ health as well as their enjoyment of using the products.In order to successfully advise the best design of product shape,there is a pressing need to investigate the suitable design parameters via experimental study on human factors evaluation.This thesis combines electromyography and pressure studies to examine the changes in neck muscles and facial pressure after wearing various VR glasses.The EMG readings are evaluated in the time domain and frequency domain,and the face pressure data are assessed using the Mann-Whitney U test for independent samples.The last experiment of surface EMG signal and facial pressure is used to determine if the newly created product fits the ergonomic standards based on the previous experimental results,product hardware,and other data for the design and modeling of a virtual reality headset.As demonstrated above,this thesis combines surface EMG signals and pressure signals for the first time,takes the human factors problem and design level as the starting point,conducts systematic human factors evaluation and experiments for the fatigue caused by virtual reality headset on neck and facial muscles,and solves some of the human factors problems brought by virtual reality products,thereby bridging the gap between human factors evaluation and virtual reality headsets.Through the above-mentioned tests and human factors evaluation methodologies,this work aims to build more reasonable and comfortable virtual reality wearable devices,thereby enhancing the usability and user experience of virtual reality headsets.
