本文提出了一种凝视交互式数字装配教学的研究，它在真实的任务设置中提供了对学生数据的并发记录。该指令允许免提凝视，作为手指点击的替代品，并支持图像旋转以及通过头部运动进行图像缩放。在两家乐高玩具店对72名儿童进行的用户研究表明，他们中的可以立即使用它。59名参与者可以记录观看时间和瞳孔放大的数据。平均而言，孩子们有一半的时间在听指导(S.D.10.9%)。记录的瞳孔大小在整个建造过程中都显示出减小的趋势，但当孩子不得不后退时除外：发现在倒退之后是瞳孔扩大。这项研究的主要贡献是证明了凝视跟踪技术能够支持健壮的交互和同时的、非侵入性的野外凝视和瞳孔数据记录。之前的研究已经发现，瞳孔扩大与任务努力的变化有关。然而，疲劳、头部运动或环境光线等其他因素也可能会产生影响。最后一部分总结了我们对这种复杂的真实任务学生数据收集的方法，并对未来的应用程序如何利用学生信息提出了建议。
This paper presents a study of a gaze interactive digital assembly instruction that provides concurrent logging of pupil data in a realistic task setting. The instruction allows hands-free gaze dwells as a substitute for finger clicks, and supports image rotation as well as image zooming by head movements. A user study in two LEGO toy stores with 72 children showed it to be immediately usable by 64 of them. Data logging of view-times and pupil dilations was possible for 59 participants. On average, the children spent half of the time attending to the instruction (S.D. 10.9%). The recorded pupil size showed a decrease throughout the building process, except when the child had to back-step: a regression was found to be followed by a pupil dilation. The main contribution of this study is to demonstrate gaze-tracking technology capable of supporting both robust interaction and concurrent, non-intrusive recording of gaze- and pupil data in-the-wild. Previous research has found pupil dilation to be associated with changes in task effort. However, other factors like fatigue, head motion, or ambient light may also have an impact. The final section summarizes our approach to this complexity of real-task pupil data collection and makes suggestions for how future applications may utilize pupil information.
