In this article, we propose a novel technique based on Head Movement tracking to explore multilayer digital content. We extend an existing method by Kazemi et al. dealing with the extraction of facial landmarks to define the “head‐gaze” of the user. We use the “head‐gaze” to calculate the users' on‐screen coordinates. Hovering the cursor over an interactive area for a given time threshold allows users to explore the next layer contents. Our experimental sessions allowed us to measure the technique's level of control and usability. Our results were promising, and users were able to interact with considerably small regions. Furthermore, our lightweight method can be used with a low‐cost camera or webcam and a wide range of screen sizes and distances.

迈向基于头部运动的多层数字内容探索系统

在本文中，我们提出了一种基于头部运动跟踪的新颖技术来探索多层数字内容。我们扩展了Kazemi等人的现有方法。处理面部标志的提取以定义用户的“凝视”。我们使用“凝视”来计算用户的屏幕坐标。将光标悬停在交互式区域上给定的时间阈值，使用户可以浏览下一层的内容。我们的实验课程使我们能够测量技术的控制水平和可用性。我们的结果令人鼓舞，并且用户能够与相当小的区域进行交互。此外，我们的轻量级方法可以与低成本相机或网络摄像头以及各种屏幕尺寸和距离配合使用。
