It is important to understand how the hand and fingers elongate and contract with hand posture for optimally fitting and comfortable gloves. Nevertheless, the measurement and analysis of the finger segments for glove designs remain largely neglected. Here, the length and proportion of the finger segments when splayed and during gripping, and between the dorsal and palm sides of 30 participants are 3D scanned and analysed. The full digit lengths change by 7.6-11.9% with hand posture, but the finger segment changes are not proportional. The ratios of the fingertip to distal interphalangeal joint/full digit, and fingertip to the proximal interphalangeal joint/full digit, are important variables. The results are validated with 10 more subjects based on ratings of a ready-to-wear sports glove. Inaccurate proportioning of the finger regions causes shifting which results in displacement and discomfort. This research contributes to glove pattern engineering, with a focus on the finger segments.
理解手部和手指在不同手势下的伸展和收缩方式对于制作合适且舒适的手套非常重要。然而，对于手套设计而言，手指部分的测量和分析仍然很大程度上被忽视。在这里，对 30 名参与者张开和握持手指以及手指背侧和掌侧的情况进行了三维扫描和分析。手部姿势会使整个手指长度发生 7.6-11.9%的变化，但手指部分的变化不成比例。指尖到远节指间关节/整个手指的比例和指尖到近节指间关节/整个手指的比例是重要的变量。基于对一款现成运动手套的评价，用另外 10 名受试者对结果进行了验证。手指区域的比例不准确会导致移位，从而产生不适和位移。这项研究对手套样板工程做出了贡献，特别是针对手指部分。
