Amplifying Vertical Linear Vection in VR Motion Ride Using Horizontal Motion Visual Stimuli: Investigating Intensities of Physical and Visual Stimuli

Abstract

The proliferation of VR attractions has increased attention to vection generation technology for enhancing perceived realism. Given the rising interest in Mixed Reality (MR) attractions―which allow users to visually interact with the real world―it is not feasible to manipulate all visual stimuli coordinates for generating linear vection. Consequently, our focus has shifted to optical illusions, capable of creating a three-dimensional effect with two-dimensional visual stimuli. We developed a dynamic visual image that amplifies perceived vertical displacement by applying such illusions to floor surfaces. This paper describes the results of three experiments with our dynamic visual image. These empirical explorations of our proposed method will facilitate the determination of actual travel distances and parameters.
