Abstract：
Combining eye tracking and virtual reality (VR) is a promising approach to tackle various applied research questions. As this approach is relatively new, routines are not established yet and the first steps can be full of potential pitfalls. The present paper gives a practice example to lower the boundaries for getting started. More specifically, I focus on an affordable add-on technology, the Pupil Labs eye tracking add-on for the HTC Vive. As add-on technology with all relevant source code available on GitHub, a high degree of freedom in preprocessing, visualizing, and analyzing eye tracking data in VR can be achieved. At the same time, some extra preparatory steps for the setup of hardware and software are necessary. Therefore, specifics of eye tracking in VR from unboxing, software integration, and procedures to analyzing the data and maintaining the hardware will be addressed. The Pupil Labs eye tracking add-on for the HTC Vive represents a highly transparent approach to existing alternatives. Characteristics of eye tracking in VR in contrast to other headmounded and remote eye trackers applied in the physical world will be discussed. In conclusion, the paper contributes to the idea of open science in two ways: First, by making the necessary routines transparent and therefore reproducible. Second, by stressing the benefits of using open source software.
摘要：
结合眼动追踪和虚拟现实（VR）是解决各种应用研究问题的一种有前途的方法。由于这种方法相对较新，例程尚未建立，第一步可能充满潜在的陷阱。本文给出了一个实践示例，以降低入门的界限。更具体地说,我专注于负担得起的附加技术，HTCVive的PupilLabs眼动追踪附加组件。作为具有GitHub上可用的所有相关源代码的附加技术，预处理的高度自由度，可视化，并分析VR中的眼动追踪数据。同时,一些额外的准备步骤的硬件和软件的设置是必要的。因此,从拆箱开始，VR中的眼球追踪细节，软件集成，以及分析数据和维护硬件的过程将得到解决。HTCVive的PupilLabs眼动追踪附加组件代表了对现有替代品的高度透明的方法。与在物理世界中应用的其他头戴式和远程眼睛跟踪器相比，VR中的眼睛跟踪的特征将被讨论。总之,本文从两个方面为开放科学的思想做出了贡献：第一，通过使必要的例程透明，因此可重复。第二,通过强调使用开源软件的好处。
