Gaze behavior in dyadic conversations can indicate active listening and attention. However, gaze behavior that is different from the engagement expected during neurotypical social interaction cues may be interpreted as uninterested or inattentive, which can be problematic in both personal and professional situations. Neurodivergent individuals, such as those with autism spectrum conditions, often exhibit social communication differences broadly including via gaze behavior. This project aims to support situational social gaze practice through a virtual reality (VR) mock job interview practice using the HTC Vive Pro Eye VR headset. We show how gaze behavior varies in the mock job interview between neurodivergent and neurotypical participants. We also investigate the social modulation of gaze behavior based on conversational role (speaking and listening). Our three main contributions are: (i) a system for fully-automatic analysis of social modulation of gaze behavior using a portable VR headset with a novel realistic mock job interview, (ii) a signal processing pipeline, which employs Kalman filtering and spatial-temporal density-based clustering techniques, that can improve the accuracy of the headset's built-in eye-tracker, and (iii) being the first to investigate social modulation of gaze behavior among neurotypical/divergent individuals in the realm of immersive VR.
在双人对话中,目光行为可以表示积极倾听和关注。然而,与神经典型社交互动期望的参与不同的目光行为可能会被解读为不感兴趣或不专注,这在个人和职业环境中都是有问题的。神经多样性个体,如自闭症谱系障碍患者,通常通过目光行为等广泛的社交沟通差异来表现。本项目旨在通过使用 HTC Vive Pro Eye VR 耳机进行虚拟现实 (VR) 模拟工作面试练习来支持情境社交目光实践。我们展示了神经多样性和神经典型参与者在模拟工作面试中目光行为的变化。我们还根据对话角色(说话和倾听)研究了目光行为的社会调节。我们的三个主要贡献是:(i) 一种使用带有新颖逼真模拟工作面试的便携式 VR 耳机进行社交目光行为自动分析的系统,(ii) 一种信号处理管道,该管道采用卡尔曼滤波和时空密度聚类技术,可以提高耳机内置眼动追踪器的准确性,以及 (iii) 首次在沉浸式 VR 领域研究神经典型/神经多样性个体的目光行为的社会调节。
