Current Technology Landscape for Collecting Hand Anthropometric Data

Historically, three methods have been used to collect hand anthropometric data. The oldest and most known method was developed in the late 1800’s, where researchers used rulers, calipers and tape measures to manually collect data from a subject’s landmarked hand, or from obvious parts of the limb that can be measured without landmarks (e.g., wrist circumference). The second method uses 2D imagery that is collected from the subject and then measured manually/digitally with rulers or calipers. A variety of devices can collect this type of imagery; including photo boxes, x-ray machines, flatbed scanners and photo copiers. These tools are convenient for collecting hand data, but can be limiting as they only collect one flat view of the hand, at one time. Over the last ten years, 3D scanning technology has been adopted for hand studies because of its’ ability to collect data quickly, and with better accuracy, as there are less steps and human error involved. 3D scanning allows researchers to collect data of an entire body part at one time, where it can be analyzed digitally beyond straight measures and circumferences. There are three types of scanners available in the market to collect hand anthropometric data, they include: 1) ones made specifically for hand scanning, 2) foot scanners and 3) hand held/mobile/tablet devices. But which 3D scanner should you select for your hand research? This can be an overwhelming decision, as there are so many options, and knowing what to look for can be confusing and quite difficult to find. Through experimentation with different equipment and hand studies, the researchers, developed a framework of key attributes that are important to selecting 3D scanners. They include: vendor/location, hand-held compatibility, scanner size, weight, envelope, supporting weight, price; along with scanner technology, timing, resolution, color capture, and file saving. Through this research, the authors desire to help others who want to purchase and conduct hand anthropometric research, to be more informed so can use their resources effectively and efficiently to have success with their work.
