在5G不断商用背景的推动下，虚拟现实（Virtual Reality，VR）技术将在生活中的诸多场景中具有广阔的前景，并且目前基于VR技术已有诸多应用。然而，若需要在虚拟场景中实现近乎真实的体验，用户指令的输入和系统的实时反馈显得尤为重要。目前在VR场景中的主流指令输入方式通常由VR头戴设备相搭配的手柄等硬体实现，由于用户需要利用手动的方式操作手柄以实现对相关动作的实现，从而降低了用户在VR场景中的沉浸式体验。为了使得VR场景适用于更加自主化和现实化的需求，本文在直播平台的支持下，开发了基于Leap Motion的手势控制系统，并且实验结果表明了所设计的手势控制系统满足了在直播场景下的基本需求。

Driven by the background of continuous commercialization of 5G, virtual reality (VR) technology will have a broad prospect in many scenes of life, and there are already many applications based on VR technology. However, the input of user commands and real-time feedback from the system are particularly important if a near-real experience is needed in virtual scenes. At present, the mainstream command input in VR scenes is usually achieved by the VR headset with the handle and other hardware, which reduces the immersive experience of the user in VR scenes because the user needs to operate the handle manually to achieve the relevant action. In order to make the VR scene suitable for more autonomous and realistic needs, this paper develops a Leap Motion-based gesture control system with the support of a live streaming platform, and the experimental results show that the designed gesture control system meets the basic needs in the live streaming scene.
