Technological ubiquity and advances in the use of networked devices, such as smartphones, have become a fundamental element in the dynamics of information in the social environment. Social problems can be discussed in these networks, receiving the aid from these devices, in order to unite community members in a network that is strengthened for common goals, transforming the local reality. The motivation for this work lies in the fact that lack of security is one of the problems that have most afflicted Brazilians in recent years. From this reality, the main objective of this study was the development of a usability analysis model suitable for smartphone applications and that allows identifying of the viability of using a collaborative security application in the social context of a city of the State of Minas Gerais, Brazil. The objective was designed to investigate how the different dimensions inherent to the social context interfere with the acceptance of technological resources, specifically, of a smartphone application in a community. Data collection was performed by applying two questionnaires to 22 participants living in the municipality (eight men and 14 women), one being a demographic survey and the other to evaluate usability focusing on users’ perception of the use of the application. The application usage scenario is family safety facing the challenges of mitigating public security issues. The analysis of the results was based on the reinterpretation of usability from the perspective of the Theory of Innovation Diffusion and the Recursive Model of Access to Technology. In order to validate the reliability of the instrument used to collect the data regarding the usability of the application, Cronbach’s alpha coefficient was applied. The result indicates that the instrument used was concise and efficient. The study enabled conclusions pointing that this type of interpretation allows us to glimpse at horizons that go beyond explicit aspects of usability, helping to understand environmental and social factors intrinsic to the context of technological diffusion in a developing society.

强调协作安全性的应用程序的可用性评估模型：一种来自社会维度的方法

技术的普遍性和诸如智能手机之类的网络设备的使用的进步已经成为社会环境中信息动态的基本要素。可以在这些网络中讨论社会问题，并从这些设备中获得帮助，以便将社区成员团结在为实现共同目标而加强的网络中，从而改变当地现实。开展这项工作的动机在于，缺乏安全感是近年来困扰巴西人最严重的问题之一。从这个现实出发，本研究的主要目的是开发适用于智能手机应用程序的可用性分析模型，该模型可以确定在巴西米纳斯吉拉斯州城市的社会环境中使用协作安全性应用程序的可行性。 。目的是研究社会背景固有的不同维度如何干扰技术资源的接受，特别是社区中智能手机应用程序的接受。数据收集是通过向居住在该市的22名参与者（八名男性和14名女性）应用两份问卷进行的，其中一项是人口统计学调查，另一项是评估可用性，重点是用户对应用程序使用的感知。应用程序使用情况是家庭安全，面临着缓解公共安全问题的挑战。对结果的分析是基于对创新扩散理论和技术获取递归模型的可用性的重新解释。为了验证用于收集有关应用程序可用性数据的仪器的可靠性，应用了Cronbach的alpha系数。结果表明所使用的仪器简洁高效。这项研究得出的结论指出，这种类型的解释使我们可以瞥见可用性的明确方面之外的视野，从而有助于了解发展中社会技术扩散的内在环境和社会因素。
