人类的感觉处理对刺激接近身体很敏感。因此，这些感知机制也会根据其位置调节VR中内容的可检测性。我们在一项用户研究中对此进行了评估，并进一步探讨了交互过程中用户表示的影响。我们还分析了如何体现和电机性能的影响，这些因素。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运动任务。同时，他们检测到出现在不同位置的视觉刺激。我们发现，在虚拟环境中主动执行运动任务时，当在用户身体附近呈现时，检测额外视觉刺激的性能更高。这种效果与用户如何被表示无关，并且仅在用户还参与次要任务时发生。我们进一步发现，与使用键盘进行交互相比，在VR中通过虚拟工具和手进行交互时，运动性能得到了改善，具体表现也有所增加。本文有助于更好地理解虚拟现实中视觉内容的可检测性，这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，体现和运动性能的影响。
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 article 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.
