Smart cities emergence has allowed a wide variety of technological services to metropolitan areas. These services can improve life quality, minimize environmental impacts, improve health service, improve security, and bear the increasing number of people in the cities. Life quality encompasses manysubjects, and accessibility for People with Disabilities (PwD) is one. In this article, smart cities focused on helping PwD are called Assistive Smart Cities (ASCs). In this sense, the article proposes a Model for Assistive Smart Cities called MASC. Related works do not cover geographically broad areas, such as cities and metropolitan regions. Moreover, they are not generic in terms of disabilities and are usually intended only for one type of disability. Given this scenario, the MASC covers large regions and supports various disabilities, such as hearing, visual impairment, and limitation of lower limb movements. Unlike the related works, MASC uses the interactions of PwD to compose histories of contexts offered as services. MASC proposes an ontology-based on ubiquitous accessibility concepts. The model evaluation focused on performance, functionality, and usability. Performance and functionality evaluations were performed using data generated by a context simulator called Siafu and data from the Open Street Maps (OSM) platform. Usability was evaluated using a smart wheelchair prototype. The results of usability show 96% acceptance regarding ease of use and 98% regarding system utility. The results indicate that the model supports massive applications, managing information to generate trails. Besides, MASC provides services for different types of users, namely PwD, healthcare professionals, and public administration.

在智慧城市中帮助残疾人的智能模型

智慧城市的出现为大都市区提供了各种各样的技术服务。这些服务可以提高生活质量,最大限度地减少对环境的影响,改善卫生服务,提高安全性,并在城市中承载越来越多的人口。生活质量包括许多主题,残疾人 (PwD) 的可及性就是其中之一。在本文中,专注于帮助残疾人的智慧城市被称为辅助智慧城市 (ASC)。从这个意义上说,本文提出了一种名为 MASC 的辅助智能城市模型。相关作品不涵盖地理广泛的区域,例如城市和大都市区。此外,它们在残疾方面不是通用的,通常仅用于一种类型的残疾。鉴于这种情况,MASC 覆盖大片区域并支持各种残疾,例如听力、视力障碍和下肢运动受限。与相关作品不同,MASC 使用 PwD 的交互来编写作为服务提供的上下文的历史。MASC 提出了一种基于无处不在的可访问性概念的本体。模型评估侧重于性能、功能和可用性。使用名为 Siafu 的上下文模拟器生成的数据和来自 Open Street Maps (OSM) 平台的数据执行性能和功能评估。使用智能轮椅原型评估可用性。可用性结果显示 96% 的易用性和 98% 的系统实用性。结果表明,该模型支持海量应用,管理信息以生成路径。此外,MASC 为不同类型的用户提供服务,即 PwD、
