User discomfort evaluation research on the weight and wearing mode of head-wearable device

Abstract

Augmented reality glasses are unlike regular glasses, its built-in camera, sensors and modules make it a small computing device capable of independent data processing. Because of the different product structures and wearing modes of AR glasses, its center of gravity and weight have become an important factor of the wearing experience. This research investigates mainly from the perspective of ergonomics and human-computer interaction, through the psychology and subjective experimental research under different structures and wearing modes, figuring out the relationship between users’ subjective discomfort for AR glasses and weight, the threshold value for each wearing mode under different weight, also figuring out the relationship between discomfort rate and the load in each support points, finally put forward a design constraints guidance to enhance the AR glasses wearing experience. The experimental results show that users have different weight thresholds for each AR glasses with different structures and wearing modes. Different wearing modes under the same weight can affect users’ feeling of discomfort.
