摘要

虚拟现实(VR)中许多沉浸式体验的一个重要组成部分是 "视差",即自我运动的错觉。传统上,vection 被描述为一种视觉现象,但最近的研究表明,vection 可以受到多种感官的影响。本研究的目的是通过操纵 VR 环境中视觉、听觉和触觉刺激的可用性,研究多感官线索对牵引力的作用。为此,研究人员向 24 名成年人(Mage = 25.04)展示了一个旋转刺激物,旨在诱发圆形吸力。所有参与者都完成了包含单一感官线索、两种线索组合或三种线索同时呈现的试验。视场(FOV)的大小在四个级别(无视觉、小、中、全)中进行调节。每次试验后,受试者都会以口头方式对视觉强度和持续时间进行评分。结果表明,当三种感觉线索单独出现时,都会诱发牵引,其中视觉线索诱发的牵引强度最高,持续时间最长。与不出现这些线索的情况相比,出现听觉和触觉线索会进一步增加牵拉强度和持续时间。这些发现支持了这样一种观点,即牵引可以通过多种类型的感觉输入来诱发,并且当多种感觉输入结合在一起时可以得到加强。

Multisensory Effects on Illusory Self-Motion (Vection): the Role of Visual, Auditory, and Tactile Cues.

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 (Mage = 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.

期刊介绍: Multisensory Research is an interdisciplinary archival journal covering all aspects of multisensory processing including the control of action, cognition and attention. Research using any approach to increase our understanding of multisensory perceptual, behavioural, neural and computational mechanisms is encouraged. Empirical, neurophysiological, psychophysical, brain imaging, clinical, developmental, mathematical and computational analyses are welcome. Research will also be considered covering multisensory applications such as sensory substitution, crossmodal methods for delivering sensory information or multisensory approaches to robotics and engineering. Short communications and technical notes that draw attention to new developments will be included, as will reviews and commentaries on current issues. Special issues dealing with specific topics will be announced from time to time. Multisensory Research is a continuation of Seeing and Perceiving, and of Spatial Vision.
