Abstract
Measurement protocols for hand anthropometry have been studied for ergonomic product design. The present study developed a 3D semi-automatic measurement protocol (3D-SAMP) which semi-automatically measures various hand dimensions using a 3D scanner. The 3D-SAMP was compared with the conventional direct measurement protocol (DMP) to examine its effectiveness. The 3D-SAMP consists of (1) fabricating a plaster cast of the hand, (2) placing landmarks on the plaster hand, (3) scanning the plaster hand with a 3D scanner, (4) automatically identifying the positions of the landmarks on the digital hand, and (5) automatically extracting hand anthropometric measurements (lengths, widths, thicknesses, and circumferences). An evaluation experiment was conducted and found the 3D-SAMP preferred to the DMP in terms of reliability, efficiency, and ease of measurement.
