摘要:

虚拟现实(VR)和增强现实(AR)技术越来越多地与眼动跟踪相结合。这种结合拓宽了这两个领域,并开辟了新的应用领域,其中视觉感知和相关的认知过程可以在交互式但仍然控制良好的环境中进行研究。然而,从交互式三维场景的眼动跟踪数据进行语义凝视分析是一个资源密集型的任务,这到目前为止一直是经济使用的障碍。在本文中,我们提出了一种新的方法,最大限度地减少时间和信息所需的注释卷的兴趣(VOIs),通过使用对象识别技术。为此,我们在使用图像增强技术从虚拟模型导出的合成数据集上训练卷积神经网络(CNN)。我们在真实和虚拟环境中评估了我们的方法,表明该方法可以与最先进的方法竞争,同时不依赖于额外的标记或预先存在的数据库,而是提供跨平台使用。

英文摘要:

Virtual-reality (VR) and augmented-reality (AR) technology is increasingly combined with eye-tracking. This combination broadens both fields and opens up new areas of application, in which visual perception and related cognitive processes can be studied in interactive but still well controlled settings. However, performing a semantic gaze analysis of eye-tracking data from interactive three-dimensional scenes is a resource-intense task, which so far has been an obstacle to economic use. In this paper we present a novel approach which minimizes time and information necessary to annotate volumes of interest (VOIs) by using techniques from object recognition. To do so, we train convolutional neural networks (CNNs) on synthetic data sets derived from virtual models using image augmentation techniques. We evaluate our method in real and virtual environments, showing that the method can compete with state-of-the-art approaches, while not relying on additional markers or preexisting databases but instead offering cross-platform use.
