Investigation of Simulator Sickness in Walking with Multiple Locomotion Technologies in Virtual Reality

Abstract

With the increasing development of Virtual Reality, locomotion has become an essential component of interaction in VR. Currently, various locomotion technologies have been developed to provide users with a natural walking experience in virtual environments. However, the multiple walking techniques impact users' walking experience in different ways. Simulator sickness is a common issue in VR experiences. Since different walking methods may influence simulator sickness differently, we conducted a user study to evaluate simulator sickness in walking with three relevant walking methods: real walking, arm-swing, and omnidirectional treadmill, and the results indicated that these three walking methods caused different levels of simulator sickness, and people perceived stronger sickness when they walked on the omnidirectional treadmill.
