A critical component to many immersive experiences in virtual reality (VR) is vection, defined as the illusion of self-motion. Traditionally, vection has been described as a visual phenomenon, but more recent research suggests that vection can be influenced by a variety of senses. The goal of the present study was to investigate the role of multisensory cues on vection by manipulating the availability of visual, auditory, and tactile stimuli in a VR setting. To achieve this, 24 adults (M_age = 25.04) were presented with a rotating stimulus aimed to induce circular vection. All participants completed trials that included a single sensory cue, a combination of two cues, or all three cues presented together. The size of the field of view (FOV) was manipulated across four levels (no-visuals, small, medium, full). Participants rated vection intensity and duration verbally after each trial. Results showed that all three sensory cues induced vection when presented in isolation, with visual cues eliciting the highest intensity and longest duration. The presence of auditory and tactile cues further increased vection intensity and duration compared to conditions where these cues were not presented. These findings support the idea that vection can be induced via multiple types of sensory inputs and can be intensified when multiple sensory inputs are combined.

虚拟现实 (VR) 中许多沉浸式体验的一个关键组成部分是矢量，定义为自我运动的错觉。传统上，矢量被描述为一种视觉现象，但最近的研究表明，矢量可能受到多种感官的影响。本研究的目标是通过操纵 VR 环境中视觉、听觉和触觉刺激的可用性来研究多感官线索对 vection 的作用。为了实现这一目标，对 24 名成年人（ M_年龄= 25.04）进行了旋转刺激，旨在诱导圆形运动。所有参与者都完成了包括单一感官提示、两个提示的组合或所有三个提示一起呈现的试验。视野 (FOV) 的大小通过四个级别进行控制（无视觉、小、中、全）。每次试验后，参与者口头评价运动强度和持续时间。结果表明，所有三种感觉线索在单独呈现时都会引起运动，其中视觉线索引起最高强度和最长持续时间。与不存在这些提示的情况相比，听觉和触觉提示的存在进一步增加了运动强度和持续时间。这些发现支持这样的观点，即运动可以通过多种类型的感觉输入引起，并且当多种感觉输入组合时可以增强。
