Visual information plays an essential role in enhancing neural activity during mental practices. Previous research has shown that using different visual scenarios during mental practices that involve imagining the movement of a specific body part may result in differences in performance. Many of these scenarios utilize the concept of embodiment, or one’s observation of another entity to be a part of oneself, to improve practice quality of the imagined body movement. We therefore hypothesized that applying immersive virtual reality headsets, with their ability to provide rich immersion and illusion by presenting egocentrically simulated virtual scenarios, and action observation to motor imagery practice will result in significant improvement. To explore the possible synergy between immersive systems and motor imagery, we analyzed the electroencephalogram signals of our participants as they were presented the same virtual hand movement scenario with two different mediums: an immersive virtual reality headset and a monitor display. Our experimental results provide evidence that the immersive virtual reality headsets induced improved rhythmic patterns with better discriminating spatial features from the brain compared to the monitor display. These findings suggest that the use of immersive virtual reality headsets, with the illusion and embodiment they provide, can effectively improve motor imagery training.

通过沉浸式虚拟现实观察动作可增强运动图像训练。

视觉信息在增强心理练习过程中的神经活动中起着至关重要的作用。先前的研究表明，在心理练习中使用不同的视觉场景，包括想象特定身体部位的运动，可能会导致性能差异。这些场景中的许多场景都利用实施例的概念，或者一个人对另一个实体的观察成为自己的一部分，以提高所想象的身体运动的练习质量。因此，我们假设使用沉浸式虚拟现实头戴式耳机，并能够通过呈现以自我为中心的虚拟场景来提供丰富的沉浸感和幻觉，并将动作观察应用于运动图像实践，将带来显着改善。为了探索沉浸式系统与运动图像之间可能的协同作用，我们分析了参与者的脑电图信号，因为他们使用两种不同的媒介呈现了相同的虚拟手部动作场景：沉浸式虚拟现实耳机和显示器显示屏。我们的实验结果提供了证据，即与显示器显示屏相比，沉浸式虚拟现实耳机能够改善节奏模式，并更好地区分大脑的空间特征。这些发现表明，沉浸式虚拟现实头戴式耳机的使用以及它们提供的错觉和体现可以有效地改善运动图像训练。我们的实验结果提供了证据，即与显示器显示屏相比，沉浸式虚拟现实耳机能够改善节奏模式，并更好地区分大脑的空间特征。这些发现表明，沉浸式虚拟现实耳机的使用以及它们提供的错觉和体现，可以有效地改善运动图像训练。我们的实验结果提供了证据，即与显示器显示屏相比，沉浸式虚拟现实耳机能够改善节奏模式，并更好地区分大脑的空间特征。这些发现表明，沉浸式虚拟现实耳机的使用以及它们提供的错觉和体现，可以有效地改善运动图像训练。
