Accessibility--> inspection methods provide an important complement to user evaluations in the development of interactive systems. However, many inspection methods tend to focus on violations of guidelines and are limited in conveying the impact of such problems when delivering their results. Drawing from the theoretical framework of Semiotic Engineering of Human–Computer Interaction, this paper presents SIM-SR—Semiotic Inspection Method Mediated by Screen Reader and an investigation to collect indicators about the method’s applicability and insights it can generate. In order to assess its applicability, we conducted three case studies employing the method, analysing how aspects of accessibility and communicability were approached and results generated. Regarding SIM-SR insights, we used WCAG 2.1 criteria to discuss how communicative breakdowns relate to accessibility guidelines and their impact. Our results show that SIM-SR went beyond identifying guidelines violations and led evaluators to consider the impact of accessibility issues on the system’s communicability and different levels of communicative breakdowns that users with visual disabilities could experience during interaction.

SIM-SR——屏幕阅读器介导的符号学检查方法：分析将可通信性引入可访问性评估表的好处

辅助功能--> 检查方法为交互系统开发中的用户评价提供了重要的补充。然而，许多检查方法往往侧重于违反准则的情况，并且在交付结果时在传达此类问题的影响方面受到限制。本文借鉴人机交互符号工程的理论框架，提出了 SIM-SR——屏幕阅读器介导的符号检查方法，并进行了一项调查，以收集有关该方法的适用性和它可以产生的见解的指标。为了评估其适用性，我们使用该方法进行了三个案例研究，分析了如何处理可访问性和可交流性的各个方面以及如何生成结果。关于 SIM-SR 见解，我们使用了 WCAG 2。1 标准来讨论沟通障碍如何与无障碍指南及其影响相关。我们的结果表明，SIM-SR 不仅可以识别违反准则的行为，还可以引导评估人员考虑可访问性问题对系统可通信性的影响，以及视障用户在交互过程中可能遇到的不同级别的通信故障。
