Online Virtual Simulation Course Design for VR Glasses Fit Analysis

Abstract

With the development of the metaverase, virtual reality technology is invading various fields. As a carrier of virtual reality (VR) technology, VR glasses have become a new type of smart wearable devices and are widely used. It’s crucial to improve the wearing comfort of VR glasses. Based on the practical requirements for industrial design education, an online course of virtual simulation for students majoring in industrial design was designed and developed. The aim of this course is to test the fit of the VR facial interface to people’s face shapes through a virtual simulation experiment, which can be conducted by five 3D Chinese statistical head models generated from 3400 3D Chinese head scans using the principal component analysis (PCA) panel. After the alignment between the facial interface and the headforms, deviation analysis was carried out and the analysis report was generated. The report contains gap analysis texture maps and data including positive max deviation, negative max deviation, positive mean deviation, negative mean deviation, and the standard deviation of the gap distribution. This online course provides a platform for industrial design students to evaluate the fit of a VR facial interface design on Chinese population effectively and can also be used as an accurate reference for the improvement of the wearing comfort for other head worn products such as glasses, headphones and masks.
