The absence of some forms of non-verbal communication in virtual reality (VR) can make VR-based group discussions difficult even when a leader is assigned to each group to facilitate discussions. In this paper, we discuss if the sensor data from off-the-shelf VR devices can be used to detect opportunities for facilitating engaging discussions and support leaders in VR-based group discussions. To this end, we focus on the detection of suppressed speaking intention in VR-based group discussions by using personalized and general models. Our extensive analysis of experimental data reveals some factors that should be considered to enable effective feedback to leaders. In particular, our results show the benefits of combining the sensor data from leaders and low-engagement participants, and the usefulness of specific HMD sensor features.

使用现成的 VR 耳机检测小组讨论中的领导机会

虚拟现实 (VR) 中缺乏某些形式的非语言交流，即使为每个小组分配了一名领导者来促进讨论，​​基于 VR 的小组讨论也会变得困难。在本文中，我们讨论了现成 VR 设备的传感器数据是否可用于检测促进参与讨论的机会，并支持基于 VR 的小组讨论的领导者。为此，我们专注于通过使用个性化和通用模型来检测基于 VR 的小组讨论中抑制的说话意图。我们对实验数据的广泛分析揭示了一些为向领导者提供有效反馈而应考虑的因素。特别是，我们的结果显示了结合来自领导者和低参与度参与者的传感器数据的好处，以及特定 HMD 传感器功能的有用性。
