Currently, the availability of technology developed to increase the autonomy of visually impaired athletes during sports is limited. The research proposed in this paper (Part I and Part II) focuses on the realization of an electromagnetic system that can guide a blind runner along a race track without the need for a sighted guide. In general, the system is composed of a transmitting unit (widely described in Part I) and a receiving unit, whose components and main features are described in this paper. Special attention is paid to the definition of an electromagnetic model able to faithfully represent the physical mechanisms of interaction between the two units, as well as between the receiving magnetic sensor and the body of the user wearing the device. This theoretical approach allows for an estimation of the signals to be detected, and guides the design of a suitable signal processing board. This technology has been realized, patented, and tested with a blind volunteer with successful results and this paper presents interesting suggestions for further improvements.
目前，为提高视障运动员在运动中的自主性而开发的技术的可用性有限。本文提出的研究（第一部分和第二部分）专注于实现一种电磁系统，可以在不需要有视力引导员的情况下引导盲人跑步者沿着赛道前进。一般来说，该系统由一个发射单元（在第一部分中有详细描述）和一个接收单元组成，本文描述了其组件和主要特点。特别关注定义一个电磁模型，该模型能够忠实地表示两个单元之间以及佩戴设备的用户身体上的接收磁传感器之间的相互作用的物理机制。这种理论方法允许对要检测的信号进行估计，并指导设计合适的信号处理板。这项技术已经被实现、专利，并通过一位盲人志愿者进行了测试，取得了成功的结果，本文还提出了进一步改进的有趣建议。
