眼球追踪设施通常仅限于监控单个人观看静态图像或预先录制的视频。在本文中，我们描述了一个系统，该系统可以研究联合行动期间与其他活动协调的视觉注意力。该软件并行连接两个眼球追踪系统并提供屏幕任务。通过根据动态屏幕区域定位眼球运动，它可以自动跟踪屏幕上移动的物体。利用现有的 SR 技术，该系统还可以将每个参与者的眼动轨迹和鼠标位置交叉投影到另一个参与者的屏幕工作空间上。该系统以与后续人类编码相同的格式保存眼球追踪和屏幕事件的完整记录，允许对多种模式进行分析。该软件提供了自发多模式通信的新方法：联合行动和联合关注。这些能力通过二维模型协作屏幕组装的实验范例得到了证明。该软件可根据开源许可证使用。
Eyetracking facilities are typically restricted to monitoring a single person viewing static images or prerecorded video. In the present article, we describe a system that makes it possible to study visual attention in coordination with other activity during joint action. The software links two eyetracking systems in parallel and provides an on-screen task. By locating eye movements against dynamic screen regions, it permits automatic tracking of moving on-screen objects. Using existing SR technology, the system can also cross-project each participant's eyetrack and mouse location onto the other's on-screen work space. Keeping a complete record of eyetrack and on-screen events in the same format as subsequent human coding, the system permits the analysis of multiple modalities. The software offers new approaches to spontaneous multimodal communication: joint action and joint attention. These capacities are demonstrated using an experimental paradigm for cooperative on-screen assembly of a two-dimensional model. The software is available under an open source license.
