We present GlassesViewer, open-source software for viewing and analyzing eye-tracking data of the Tobii Pro Glasses 2 head-mounted eye tracker as well as the scene and eye videos and other data streams (pupil size, gyroscope, accelerometer, and TTL input) that this headset can record. The software provides the following functionality written in MATLAB: (1) a graphical interface for navigating the study- and recording structure produced by the Tobii Glasses 2; (2) functionality to unpack, parse, and synchronize the various data and video streams comprising a Glasses 2 recording; and (3) a graphical interface for viewing the Glasses 2's gaze direction, pupil size, gyroscope and accelerometer time-series data, along with the recorded scene and eye camera videos. In this latter interface, segments of data can furthermore be labeled through user-provided event classification algorithms or by means of manual annotation. Lastly, the toolbox provides integration with the GazeCode tool by Benjamins et al. (2018), enabling a completely open-source workflow for analyzing Tobii Pro Glasses 2 recordings.
我们介绍了 GlassesViewer，这是一款用于查看和分析 Tobii Pro Glasses 2 头戴式眼动追踪器的眼动追踪数据以及该头戴设备可以记录的场景视频和其他数据流（瞳孔大小、陀螺仪、加速度计和 TTL 输入）的开源软件。该软件提供了以下用 MATLAB 编写的功能：（1）用于浏览 Tobii Glasses 2 生成的研究和记录结构的图形界面；（2）用于解包、解析和同步组成 Glasses 2 记录的各种数据和视频流的功能；（3）用于查看 Glasses 2 的注视方向、瞳孔大小、陀螺仪和加速度计时间序列数据以及记录的场景和眼睛摄像机视频的图形界面。在后一个界面中，还可以通过用户提供的事件分类算法或手动注释对数据段进行标记。最后，该工具箱提供了与 Benjamins 等人（2018）的 GazeCode 工具的集成，为分析 Tobii Pro Glasses 2 记录提供了完全开源的工作流程。
