目的定义静态、动态和认知匹配以及它们与外系统的相互作用，并记录使用这些匹配特征来指导外系统设计的开放研究需求。由于匹配依赖于与任务设置和用户相关的持续交互，在优化这种有限的匹配定义时，定制设备的尝试具有局限性。方法通过有针对性的文献综述，提出了定义外系统匹配的三个特征的概念框架：静态、动态和认知。结果静态匹配考虑了人与设备之间的一致性，需要了解目标用户的人体测量特征和设备的几何特征。Dynamic Fit评估人员和设备如何移动和相互作用，重点放在两个系统之间的相对对齐上。认知匹配考虑了人类信息处理的各个阶段，包括躯体感觉、执行功能和运动选择。在外部系统存在的情况下，人类的认知能力应该能够处理与任务和刺激相关的信息。动态匹配和认知匹配是以特定任务的方式操作的，而静态匹配可以考虑预定义的姿势。结论需要更深入地了解外部系统是如何匹配个体的，以确保良好的人类系统性能。开发评估不同匹配特性的方法是必要的。提出了应用方法来提供关于身体和认知特性的外系统评估。
ObjectiveTo define static, dynamic, and cognitive fit and their interactions as they pertain to exosystems and to document open research needs in using these fit characteristics to inform exosystem design.BackgroundInitial exosystem sizing and fit evaluations are currently based on scalar anthropometric dimensions and subjective assessments. As fit depends on ongoing interactions related to task setting and user, attempts to tailor equipment have limitations when optimizing for this limited fit definition.MethodA targeted literature review was conducted to inform a conceptual framework defining three characteristics of exosystem fit: static, dynamic, and cognitive. Details are provided on the importance of differentiating fit characteristics for developing exosystems.ResultsStatic fit considers alignment between human and equipment and requires understanding anthropometric characteristics of target users and geometric equipment features. Dynamic fit assesses how the human and equipment move and interact with each other, with a focus on the relative alignment between the two systems. Cognitive fit considers the stages of human-information processing, including somatosensation, executive function, and motor selection. Human cognitive capabilities should remain available to process task- and stimulus-related information in the presence of an exosystem. Dynamic and cognitive fit are operationalized in a task-specific manner, while static fit can be considered for predefined postures.ConclusionA deeper understanding of how an exosystem fits an individual is needed to ensure good human-system performance. Development of methods for evaluating different fit characteristics is necessary.ApplicationMethods are presented to inform exosystem evaluation across physical and cognitive characteristics.
