自人机交互领域诞生以来，预防错误一直是一个定向目标，特别注重通过适当的技术设计最大限度地减少人为错误。然而，对于设计人员如何最好地支持不可避免会犯错误的技术的用户的探索相对较少。我们提出了针对视障人士的导航技术领域的混合方法研究。我们研究了用户如何应对实际使用场景中发生的设备错误。与可用系统必须无错误的传统观点相反，我们发现 42% 的错误是用户可以接受的。错误的接受程度取决于错误类型、建筑特征和环境背景。此外，即使用户可以接受技术错误，附近其他人的误导性社交反应也会对用户体验产生负面影响。最后，我们提出了包含错误的设计建议，同时还支持用户对技术系统中的错误进行管理。
Prevention of errors has been an orienting goal within the field of Human-Computer Interaction since its inception, with particular focus on minimizing human errors through appropriate technology design. However, there has been relatively little exploration into how designers can best support users of technologies that will inevitably make errors. We present a mixed-methods study in the domain of navigation technology for visually impaired individuals. We examined how users respond to device errors made in realistic scenarios of use. Contrary to conventional wisdom that usable systems must be error-free, we found that 42% of errors were acceptable to users. Acceptance of errors depends on error type, building feature, and environmental context. Further, even when a technical error is acceptable to the user, the misguided social responses of others nearby can negatively impact user experience. We conclude with design recommendations that embrace errors while also supporting user management of errors in technical systems.
