A special strain of situational impairment, termed “Severely Constraining Situational Impairments” (SCSI), was explored from a novel qualitative perspective. When a severely impairing event presents, the multitude and complexity of ambient agents are often overwhelming, leading to the inability to devise a solution. To classify and help design for them, interviews and participatory design-based workshops were conducted, revealing that (1) participants attempt to complete mobile transactions, even if it might place them in considerable danger, and (2) significant differences exist in the modalities and steps used to address the onset of a severely impairing event versus those of a non-severe situational impairment. Design solutions generated from the workshops indicated that users want technology to take a larger role in helping manage the added cognitive load inherent in severely impairing events. The revealed implications for design indicate that to maximize the user experience in the mobile device transaction space, designers must account for the presence of these SCSI and the unique design specifications that they require.

从新颖的定性观点出发，探索了一种特殊的情境障碍，称为“严重情境障碍”（SCSI）。当出现严重损害事件时，环境代理的数量和复杂性往往不堪重负，导致无法设计解决方案。为了对他们进行分类和帮助设计，进行了访谈和基于设计的参与性研讨会，结果表明：（1）参与者试图完成移动交易，即使可能会给他们带来相当大的危险，并且（2）方式上存在重大差异以及用于解决严重损害事件与非严重情况损害的事件的步骤。研讨会产生的设计解决方案表明，用户希望技术在帮助管理严重受损事件所固有的额外认知负担方面发挥更大的作用。对设计的揭示意义表明，为了最大程度地在移动设备交易空间中获得用户体验，设计人员必须考虑这些SCSI的存在及其所需的独特设计规范。
