Abstract
Eye trackers based on video-oculographic (VOG) methods are a convenient means for oculomotor research. This work focused on the development of a VOG device that allows mobile eye tracking. It was especially designed to support a head-mounted gaze driven camera system presented in a companion paper [Wagner et al. 2006] (see Figure 1). The target applications of such a device can be seen in surgery, medical and behavioral sciences as well as in the documentation and teaching of manual tasks. One major aim was the design of a lightweight head mount at low costs. Since the actuators of the gaze camera require close-to-real-time control, the software was implemented on standard PC-hardware by using well-known VOG algorithms that were optimized for short latencies.
基于视频眼动学(VOG)方法的眼动仪是眼动研究的一种便捷手段。这项工作的重点是开发一种允许移动眼动追踪的VOG设备。它是专门为支持一种头戴式凝视驱动相机系统而设计的,该系统在一篇配套论文[Wagner et al. 2006]中提出(见图1)。这种设备的目标应用可以在外科、医学和行为科学中看到,也可以在手工任务的文档和教学中看到。一个主要的目标是设计一种低成本的轻量化头戴装置。由于凝视相机的执行器需要接近实时的控制,因此该软件是通过使用著名的VOG算法在标准pc硬件上实现的,该算法针对短延迟进行了优化。
