人体是一个复杂的生物力学系统，表现出许多变化。可穿戴产品应该兼具功能性和舒适性。它们需要与最终用户的身体紧密而精确地配合。目前设计人体产品的方法依赖于一维人体测量和不切实际的人体模型，例如由简单的表面构建，如球体和圆柱体通过样条连接。随着3D扫描的兴起，无数精确的3D人体模型成为可能。在本文中，我们提出了一个框架，将这种三维形状信息用于可穿戴产品的开发。我们为实现这一扩展而引入的关键概念是一个丰富的形状模型：人体的统计形状模型，其中还包含所有1D人体测量数据。通过丰富的形状模型，可以用给定的一组人体特征来参数化三维形状。因此，只需调整个体的人体测量值，就可以获得个体形状的密集几何信息。通过在生成的三维表面上进行设计，可以获得与个人形状紧密贴合的产品。因此，我们扩展了将一维人体测量数据与产品尺寸联系起来的方法。这导致了三种设计策略，将身体形状与产品几何形状联系起来：集体适合的设计，集群内适合的设计和个人适合的设计。对每种策略进行了解释和研究，并设计了适合人类头部的可穿戴式脑电图耳机。(C) 2018 Elsevier B.V.版权所有
The human body is a complex biomechanical system that exhibits many variations. Wearable products should be both functional and comfortable. They require a close and accurate fit to the body of the end user. Current approaches to design body near products rely on 1D anthropometry and unrealistic manikins, e.g. constructed from simple surfaces such as spheres and cylinders connected by splines. With the uprising of 3D scanning, a myriad of accurate 3D body models becomes available. In this paper we present a framework to use this 3D shape information in the development of wearable products. The key concept that we introduce to achieve this extension, is an enriched shape model: a statistical shape model of the human body that also contains all 1D anthropometric data in it. With enriched shape models, a 3D shape can be parameterized with a given set of anthropometric features. Thus the dense geometric information of an individual's shape can be obtained simply by tuning that individual's anthropometric values. By designing on the generated 3D surface, a product can be obtained that closely fits the individual's shape. We thus extend the method of linking 1D anthropometric data with the dimensions of a product. This results in three design strategies that link both body shape with product geometry: design for collective fit, design for fit within clusters and design for individual fit. Each strategy is explained and studied with the design of wearable EEG headsets that fits the human head. (C) 2018 Elsevier B.V. All rights reserved.
