注视跟踪是一项重要的技术，因为系统可以从人正在看什么和在哪里给出关于人的信息。已经有许多尝试使用监视器或可穿戴设备来制造鲁棒且准确的注视跟踪器。然而，这些装置通常需要每个会话的精细个体校准和/或需要人佩戴设备，这可能不适合某些情况。在本文中，我们提出了一个强大的和完全非侵入性的视线跟踪系统，既不涉及复杂的校准，也不使用可穿戴设备。我们通过建立一个实时系统，有效地使它通过直接的眼睛反射分析来实现这一点。我们还展示了我们的系统，包括幼儿实验的几个有趣的应用。
Gaze tracking is an important technology as the system can give information about a person from what and where the person is seeing. There have been many attempts to make robust and accurate gaze trackers using either monitor or wearable devices. However, those contraptions often require fine individual calibration per session and/or require a person wearing a device, which may not be suitable for certain situations. In this paper, we propose a robust and a completely noninvasive gaze tracking system that involves neither complex calibrations nor the use of wearable devices. We achieve this via direct eye reflection analysis by building a real-time system that effectively enables it. We also show several interesting applications for our system including experiments with young children.
