The Internet of Things envisions that objects of everyday life will be equipped with sensors, microcontrollers, transceivers for digital communication and suitable protocol which communicates among them and with users, becoming an integral part of Internet. Due to the growing developments in digital technologies, Smart Cities have been equipped with different electronic devices based on IoT and several applications are being created for most diverse areas of knowledge making systems more efficient. However, Assistive technology is a field that is not enough explored in this scenario yet. In this work, an integrated framework with an IoT architecture customized for an electronic cane (electronic travel aid designed for the visually impaired) has been designed. The architecture is organized by a five-layer architecture: edge technology, gateway, Internet, middleware and application. This new feature brings the ability to connect to environment devices, receiving the coordinates of their geographic locations, alerting the user when it is close to anyone of these devices and sending those coordinates to a web application for smart monitoring. Preliminary studies and experimental tests with three blind users of the Cane show that this approach would contribute to get more spatial information from the environment improving mobility of visually impaired people.

物联网构想，日常生活对象将配备传感器，微控制器，用于数字通信的收发器以及在它们之间以及与用户进行通信的合适协议，从而成为Internet不可或缺的一部分。由于数字技术的不断发展，智能城市已经配备了基于IoT的不同电子设备，并且正在为最多样化的知识领域创建多个应用程序，从而使系统变得更加高效。但是，在这种情况下，辅助技术领域还没有得到足够的研究。在这项工作中，设计了一个集成框架，该框架具有为电子手杖（为视障人士设计的电子旅行辅助设备）定制的IoT架构。该架构由五层架构组成：边缘技术，网关，互联网，中间件和应用程序。这项新功能使您能够连接到环境设备，接收其地理位置的坐标，在用户靠近这些设备中的任何一个时向用户发出警报，并将这些坐标发送到Web应用程序以进行智能监控。对三个盲人使用者的初步研究和实验测试表明，这种方法将有助于从环境中获取更多空间信息，从而改善视力障碍者的活动能力。
