Using full-color hand-held three-dimensional scanners allows researchers to gather anthropometric data outside of a lab setting. The ability to gather a broader and more diverse database is essential to the fit and sizing of products. However, full-color hand-held three-dimensional scanning has not been fully validated as a methodology to take accurate measurements for the hand. This study aimed to examine three different tools for collecting anthropometric data for the hand by their precision. The anthropometric methods compared include tools used in traditional anthropometry, such as a small-bone caliper and tape measure and two (2) full-color hand-held three-dimensional scanners (Occipital Structure Sensor and Artec Leo). Twelve (12) three-dimensional hand scans were 3D printed with a Creality CR-10 three-dimensional printer using PLA materials. The three-dimensional scans were a part of a more extensive database, and the chosen scans represented a range of handbreadth measurements. Eight traditional anthropometric measurements, including length, breadth, and circumference, were collected to assess the precision of manual anthropometric measurements compared to digital measurements from the Occipital Structure Sensor and the Artec Leo. The results from this study showed no statistically significant differences between the manual anthropometric measurements and the digital measurements from the Artec Leo. There were limited statistical differences between the manual anthropometric measurements and the digital measurements from the Occipital Structure Sensor. There were limited statistical differences between the digital measurements from the Occipital Structure Sensor and the digital measurements from the Artec Leo. The information provided in this study will benefit the collection of anthropometric data for the hand by researchers. Three-dimensional technology and processes offer more opportunities to collect data for the hand, which will help improve the design of products that interact with the hand.
