A Visible Functional Grasp to Measure the Complete Hand

Glove and tools are designed to protect our hands, but manufacturers are limited by the available anthropometric hand data, which fails to reflect functional measurement changes of the hand while performing tasks. Advancements in 3D scanning technology have improved the ability to capture data, but minimal research has focused on capturing functional hand dimensions. The purpose of this study was to develop a comprehensive protocol to capture the dorsal and palmar side of the hand in functional positions across a large population using the Artec Leo. The development of this protocol considered the following elements; scanning technology, hand positions, hand support apparatuses, scanning platforms, and standardization across a population. Two functional hand positions, splayed and grasp, were selected based on clear visibility of the palmar side. The protocol and final scans contributed to a robust anthropometric database to improve the design, fit, and function of products for hands.
