论文摘要
人类感觉处理对刺激与身体的接近敏感。因此，这些感知机制还可以根据其位置调节VR中内容的可检测性。我们在用户研究中评估了这一点，并进一步探讨了在交互期间用户表示的影响。我们还分析了这些因素如何影响实施方案和运动性能。在双任务范式中，参与者通过虚拟手，虚拟控制器或键盘执行了电动机任务。同时，他们检测到在不同位置出现的视觉刺激。我们发现，尽管在虚拟环境中积极执行电动机任务，但在用户身体附近呈现时，检测其他视觉刺激的性能较高。此效果与用户的表示方式无关，并且仅在用户也从事次要任务时才发生。与与键盘交互相比，通过虚拟工具和手相互作用，我们进一步发现了运动性能和增加的实施例。这项研究有助于更好地理解VR中视觉内容的可检测性，具体取决于其在虚拟环境中的位置，以及不同用户表示对信息处理，实施例和运动性能的影响。
Human sensory processing is sensitive to the proximity of stimuli to the body. It is therefore plausible that these perceptual mechanisms also modulate the detectability of content in VR, depending on its location. We evaluate this in a user study and further explore the impact of the user's representation during interaction. We also analyze how embodiment and motor performance are influenced by these factors. In a dual-task paradigm, participants executed a motor task, either through virtual hands, virtual controllers, or a keyboard. Simultaneously, they detected visual stimuli appearing in different locations. We found that, while actively performing a motor task in the virtual environment, performance in detecting additional visual stimuli is higher when presented near the user's body. This effect is independent of how the user is represented and only occurs when the user is also engaged in a secondary task. We further found improved motor performance and increased embodiment when interacting through virtual tools and hands in VR, compared to interacting with a keyboard. This study contributes to better understanding the detectability of visual content in VR, depending on its location in the virtual environment, as well as the impact of different user representations on information processing, embodiment, and motor performance.
