ITR: Contributions of Eye Movements and Shared Attention to Collaborative Tasks

在远程协作中，合作伙伴可以访问的信息比面对面协作少得多。这个项目使用心理学实验来检验知道搭档在看哪里会如何影响合作任务的表现和策略。第一阶段的问题是：当伴侣们身体上共同在场时，他们如何意识到对方在哪里，他们如何获得共同的注意力？第二阶段将这些基本结果应用于远程协作；伴侣们戴着眼睛追踪器，将注视信息传送到对方的电脑显示器上。探索了任务和表征的空间：任务以系统的方式变化（例如，一些任务适合并行活动，而另一些任务则需要对每一步达成共识），并且比较了相同凝视信息的不同表征。目标是了解哪种表示最适合哪些任务。随着技术的进步，眼球追踪变得更容易、更不麻烦、更便宜，基于目光的计算机界面可能有一天会加入无处不在的输入设备的行列，比如鼠标。如果要将这项技术整合到“每个公民界面”中，就必须了解人们如何使用注视中的信息来实现共同关注的焦点。这可能为以计算机为媒介的协作提供新技术的基础。

During remote collaboration, partners have access to much less information than during face-to-face collaboration. This project uses psychological experiments to examine how knowing where a partner is looking affects performance and strategies on collaborative tasks. Phase 1 asks: When partners are physically co-present, how aware are they of where the other is attending, and how do they achieve shared attention? Phase II applies these basic results to remote collaborations; partners wear eye-trackers that transmit gaze information to each other's computer displays. A space of tasks and representations is explored: Tasks are varied in systematic ways (e.g., some lend themselves to parallel activity, while others require consensus for each step), and different representations of the same gaze information are compared. The goal is to understand which representations work best for which tasks. With technological advances making eyetracking easier, less cumbersome, and more affordable, a gaze-based computer interface may someday join the ranks of ubiquitous input devices like the mouse. If this technology is to be integrated into the "every citizen interface," it is necessary to understand how people use the information in gaze to achieve a joint focus of attention. This could provide the foundations for new technology for computer-mediated collaboration.
