摘要

在各个领域,虚拟现实(VR)已成为模拟特定场景和在受控和安全条件下促进培训的重要工具。由于周边视觉在许多情况下都起着至关重要的作用,因此在 VR 模拟中必须适当考虑周边视觉。然而,虽然在 VR 中对周边视觉进行了研究,但却很少将 VR 与真实世界(RW)进行比较。因此,本研究旨在比较 RW 和 VR 对周边视觉刺激和视野(FOV)的反应时间(RT)。这种比较是通过维也纳测试系统的周边感知-R(PP-R)和编程虚拟复制品来实现的。虚拟复制品还经过了额外的测试,结果显示,RT 的可靠性较好,但对被试视场角的测量结果却只有中等至较差的可靠性。两种环境的比较结果表明,在 VR 环境中对周围视觉刺激的反应时间比在 RW 环境中慢。观察到的这一差异与之前调查对眼窝刺激的反应时间的研究结果一致,部分原因可能是所使用的硬件和软件配置的延迟。尽管如此,在两种条件下观察到的反应时间之间的相关性表明,外围视野内的视觉处理过程具有可比性,并肯定了在 VR 中复制真实的 PP-R 的正确性。总之,研究结果支持使用 VR 作为练习和检查特定场景(包括周边视觉)的工具。VR 和 RW 在反应时间上的差异强调了在 VR 研究中继续检查硬件和软件组件的必要性。

Comparative Analysis of Visual Field Characteristics and Perceptual Processing in Peripheral Vision Between Virtual Reality and Real World

Comparative Analysis of Visual Field Characteristics and Perceptual Processing in Peripheral Vision Between Virtual Reality and Real World

In various domains, virtual reality (VR) has emerged as a valuable tool for simulating specific scenarios and facilitating training within controlled and secure conditions. As peripheral vision plays a crucial role in numerous contexts, it must be duly considered in VR simulations. However, while peripheral vision was examined in VR, comparisons between VR and the real world (RW) are rarely made. Therefore, this study is aimed at comparing RW and VR reaction times (RTs) to peripheral visual stimuli and the field of view (FOV). This comparison is achieved using the peripheral perception-R (PP-R) of the Vienna Test System and a programmed virtual replica. The virtual replica underwent additional testing, revealing good reliability for RTs but only moderate to poor for measurements of the participant’s FOV. The comparison between the two environments indicates slower RTs to peripheral visual stimuli in VR than in RW. This observed discrepancy is consistent with the results of previous studies investigating RTs to foveal stimuli and can be partially explained by the latencies in the hardware and software configurations used. Nevertheless, the observed correlations between the RTs in both conditions suggest comparable visual processing within the peripheral visual field and affirm the decent replication of the real PP-R in VR. Overall, the study’s results support the usage of VR as a tool for practicing and examining specific scenarios, including peripheral vision. The discrepancies revealed in the RTs between VR and RW emphasize the need to continue examining hardware and software components in VR research.
