沉浸式虚拟环境（IVE）为非语言交流的实验研究提供了丰富的可能性。在这里，测试了“数字变色龙”效应——这表明虚拟演讲者（代理）如果模仿他们的头部动作，就会更有说服力。使用专门构建的 IVE，我们重新创建了“数字变色龙”实验的全身模拟版本。代理的行为在三种情况下被操纵：1）模仿（变色龙），其中复制参与者的点头；2）回放（点头狗），使用前一个参与者回放的点头，因此与内容无关；3）原始（人类），其中使用预先录制的演员的动作。结果并不支持最初发现的不同条件下代理人说服力评级存在差异的结论。然而，动作捕捉数据揭示了 a) 说话者和听众的实时动作 b) 原始条件、模仿条件和回放条件之间的系统差异。我们的结论是，自动模仿模型过于简单化，这种范式必须解决非语言交互的交互动态才能充分发挥其潜力。
Immersive virtual environments (IVEs) present rich possibilities for the experimental study of non-verbal communication. Here, the 'digital chameleon' effect, -which suggests that a virtual speaker (agent) is more persuasive if they mimic their addresses head movements-, was tested. Using a specially constructed IVE, we recreate a full-body analogue version of the 'digital chameleon' experiment. The agent's behaviour is manipulated in three conditions 1) Mimic (Chameleon) in which it copies the participant's nodding 2) Playback (Nodding Dog) which uses nods from playback of a previous participant and are therefore unconnected with the content and 3) Original (Human) in which it uses the prerecorded actor's movements. The results do not support the original finding of differences in ratings of agent persuasiveness between conditions. However, motion capture data reveals systematic differences in a) the real-time movements of speakers and listeners b) between the Original, Mimic and Playback conditions. We conclude that the automatic mimicry model is too simplistic and that this paradigm must address the reciprocal dynamics of non-verbal interaction to achieve its full potential.
