在多模态远程呈现系统中，经常发生由丢包或通信延迟引起的时间中断和延迟。众所周知，这些人工制品可以影响存在感。然而，丢包和通信延迟如何影响多感官事件的时间感知在很大程度上是未知的。本文模拟了视觉模态下的随机丢包和通信延迟，并研究了它们对视-触觉碰撞时间判别的影响。我们的研究结果表明，跨模事件的同步感知对丢包率非常敏感。丢包造成时间延迟的印象，影响后续事件的感知。随着丢包率的增加，视觉事件的感知时间呈线性增加，时间分辨能力下降。感知时间也受到通信延迟的影响，导致时间被略微高估。
Temporal discontinuities and delay caused by packet loss or communication latency often occur in multimodal telepresence systems. It is known that such artifacts can influence the feeling of presence [1]. However, it is largely unknown how the packet loss and communication latency affect the temporal perception of multisensory events. In this article, we simulated random packet dropouts and communication latency in the visual modality and investigated the effects on the temporal discrimination of visual-haptic collisions. Our results demonstrated that the synchronous perception of crossmodal events was very sensitive to the packet loss rate. The packet loss caused the impression of time delay and influenced the perception of the subsequent events. The perceived time of the visual event increased linearly, and the temporal discrimination deteriorated, with increasing packet loss rate. The perceived time was also influenced by the communication delay, which caused time to be slightly overestimated.
