Abstract

This paper presents a low-cost gaze tracking solution for bedbound people composed of free-ware tracking software and commodity hardware. Gaze interaction is done on a large wall-projected image, visible to all people present in the room. The hardware equipment leaves physical space free to assist the person. Accuracy and precision of the tracking system was tested in an experiment with 12 subjects. We obtained a tracking quality that is sufficiently good to control applications designed for gaze interaction. The best tracking condition were achieved when people were sitting up compared to lying down. Also, gaze tracking in the bottom part of the image was found to be more precise than in the top part.

床上的凝视互动
本文提出了一种由免费软件和商用硬件组成的低成本卧床患者注视跟踪解决方案。凝视互动是在一个巨大的墙壁投影图像上完成的,房间里的所有人都能看到。硬件设备为辅助人员留下了自由的物理空间。通过对12名受试者的实验,验证了跟踪系统的准确性和精密度。我们获得了足够好的跟踪质量来控制为凝视交互设计的应用程序。与躺着相比,人们坐着时的追踪效果最好。此外,在图像底部的凝视跟踪被发现比在图像顶部更精确。
