凝视跟踪（GT）系统已经吸引了研究人员以及商业部门的注意。商业系统很容易获得，但它们通常以相同的尺寸制造。在这项研究中，我们提出了一个三维（3-D）-可打印的框架和一个开源的系统，以制造一个可穿戴GT系统具有低成本的配置和合理的性能。3D打印机实现了可重复和可调整的设计。GT硬件的估计价格不到100欧元，系统的平均精度为2.58°。我们的GT系统具有24 Hz的采样率，可以分析人类兴趣点。本研究的另一个贡献是使用我们提出的GT和机器学习来开发感兴趣对象的自动识别。这个组合系统的输出是一个由标记对象组成的数据库。具有最高频率的标签指示对应用户最感兴趣的对象。我们的组合系统具有7 Hz的采样率和3.8%的分类误差。
Gaze tracking (GT) systems have attracted the attention of researchers as well as the commercial sector. Commercial systems are readily available, but they are usually fabricated at the same size. In this study, we propose a three-dimensional (3-D)-printable frame and an open-source system to fabricate a wearable GT system with low-cost configuration and reasonable performance. A 3-D printer achieves repeatable and adjustable design. The estimated price to make the GT hardware is less than €100, and the system's average accuracy is 2.58°. Our GT system has a 24-Hz sampling rate, which can analyze human interest points. Another contribution of this study is developing the automatic discrimination of interest objects using our proposed GT and machine learning. The output of this combination system is a database that consists of labeled objects. The label with the highest frequency indicates the object of the highest interest for a corresponding user. Our combination system has a 7-Hz sampling rate and a 3.8% classification error.
