There is a long history of interest in looking behavior during human interaction. With the advance of (wearable) video-based eye trackers, it has become possible to measure gaze during many different interactions. We outline the different types of eye-tracking setups that currently exist to investigate gaze during interaction. The setups differ mainly with regard to the nature of the eye-tracking signal (head- or world-centered) and the freedom of movement allowed for the participants. These features place constraints on the research questions that can be answered about human interaction. We end with a decision tree to help researchers judge the appropriateness of specific setups.

在人类互动过程中观察行为的兴趣由来已久。随着（可穿戴）基于视频的眼动仪的进步，在许多不同的交互过程中测量凝视已经成为可能。我们概述了当前存在的用于调查交互过程中凝视的不同类型的眼动追踪设置。设置的不同主要在于眼动追踪信号的性质（以头部或世界为中心）和参与者允许的活动自由度。这些特征限制了可以回答有关人类互动的研究问题。我们以决策树结束，以帮助研究人员判断特定设置的适当性。
