Assistive technologies nowadays have an increasing application in overcoming the everyday needs of visually impaired persons. Going to the grocery store for groceries is a challenge for any visually impaired person who moves without a personal assistant. Creating a perception of the space in which the person is located and the possibility of orientation in such an environment is significantly reduced. The solutions and services currently available are based solely on reading products using some form of assistive technology. In this research, user needs were analyzed to define the necessary information to master the shopping process. The research aims to define a conceptual system architecture to deliver InnIoTShop information service to users moving through smart stores. The proposed architecture is based on the IoT concept, and an InnIoTShop service taxonomy has been created for this service. For data collection, processing, and fusion, the concept of Fog/Cloud Computing and M2M and M2H technology was used, which enables the adaptation of information to visually impaired persons. The paper also validated specific elements of the system architecture, which confirmed individual service functionalities' operation.

如今，辅助技术在克服视觉障碍者的日常需求中的应用越来越广泛。对于任何没有私人助理而行动不便的视力障碍人士来说，去杂货店买杂货都是一个挑战。在这样的环境中，人们对人所处的空间的感知以及定向的可能性大大降低了。当前可用的解决方案和服务完全基于使用某种形式的辅助技术阅读产品。在这项研究中，分析了用户需求以定义必要的信息以掌握购物过程。该研究旨在定义一种概念性的系统架构，以向通过智能商店移动的用户提供InnIoTShop信息服务。拟议的架构基于IoT概念，并且已为此服务创建了InnIoTShop服务分类。在数据收集，处理和融合中，使用了雾/云计算以及M2M和M2H技术的概念，从而可以使信息适应视障人士。本文还验证了系统体系结构的特定元素，从而确认了各个服务功能的运行。
