普遍的基于眼睛的交互指的是基于眼睛的交互在日常生活中变得无处不在的视觉，例如在环境中的多个显示器上。虽然当前的头盔眼球跟踪器很好地与类似距离处的显示器交互，但是场景摄像机通常不能覆盖远程和近距离显示器，例如墙上的公共显示器和手持便携设备。在这篇文章中，我们描述了一种方法，允许在多个这样的显示器上进行稳健的检测和凝视映射。我们的方法使用一个额外的场景摄像头来扩展眼睛跟踪器的观察和凝视映射区域，并根据视图中的显示自动在两个摄像头之间切换。初步研究结果表明，我们的系统达到了与单摄像头系统相似的凝视估计精度，同时提高了可用性。
Pervasive eye-based interaction refers to the vision of eye-based interaction becoming ubiquitously usable in everyday life, e. g. across multiple displays in the environment. While current head-mounted eye trackers work well for interaction with displays at similar distances, the scene camera often fails to cover both remote and close proximity displays, e. g. a public display on a wall and a handheld portable device. In this paper we describe an approach that allows for robust detection and gaze mapping across multiple such displays. Our approach uses an additional scene camera to extend the viewing and gaze mapping area of the eye tracker and automatically switches between both cameras depending on the display in view. Results from a pilot study show that our system achieves a similar gaze estimation accuracy to a single-camera system while at the same time increasing usability.
