Losing the ability to communicate inhibits social contact, creates feelings of frustration and isolation and complicates personal comfort and medical care. Progressive diseases such as amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS) can cause severe motor disabilities that make communication through traditional means difficult, slow, and exhausting, even with the support of augmentative and alternative communication (AAC) systems. Using a design science research approach, we seek to improve the communication process for individuals with severe motor disabilities. We develop a series of design requirements to inform the creation and evaluation of an artefact, an AAC system that incorporates context-aware user profiles to improve the communication process for individuals with severe motor disabilities. We derive prescriptive knowledge through the creation of design principles based on our findings and justify these design principles using the lens of media synchronicity theory (MST). This research identifies opportunities for further research related to MST and provides insights to inform those designing communication systems for individuals that rely on AAC systems.

上下文感知用户配置文件可提高严重运动障碍人士的媒体同步性

失去沟通能力会抑制社交接触，产生沮丧和孤立感，并使个人舒适度和医疗护理复杂化。渐进性疾病，如肌萎缩侧索硬化 (ALS) 和多发性硬化症 (MS)，会导致严重的运动障碍，即使在增强和替代交流 (AAC) 系统的支持下，通过传统方式进行交流也变得困难、缓慢和疲惫。使用设计科学研究方法，我们寻求改善患有严重运动障碍的个人的交流过程。我们制定了一系列设计要求，为人工制品的创建和评估提供信息，这是一个 AAC 系统，它结合了上下文感知用户配置文件，以改善严重运动障碍者的交流过程。我们通过基于我们的发现创建设计原则来获得规范性知识，并使用媒体同步理论 (MST) 的镜头证明这些设计原则的合理性。这项研究确定了与 MST 相关的进一步研究的机会，并为那些为依赖 AAC 系统的个人设计通信系统的人提供了见解。
