Abstract—Detailed analysis of the physical motions of real agricultural workers is meaningful, especially in terms of passing on the traditional manual skills of experienced workers. By investigating the manual daily tasks of outdoor workers, we developed wearable sensing systems. Focusing on traditional skills, we established a system of providing vocal instructions to inexperienced workers to improve their motions and postures. Timeline acceleration and angular velocity data were recorded by sensors attached to the arms and waist of the users, and the hoe they used. Data were sent to original programs installed on a laptop computer carried in a knapsack. Data were logged and processed using various methods. Vocal instructions that we recorded previously were sent to the inexperienced workers through an earphone to improve their agricultural techniques. Furthermore, we visually observed the workers with a video camera and analyzed the images with software using Optical Flow. We obtained detailed data related to timeline analysis. The analyses not only confirm the usefulness of the system but also reveal subtle changes graphically and numerically. We thus demonstrated that the system can improve worker motions by sending vocal instructions.
Index Terms—changes due to vocal instructions, traditional agricultural skills, acceleration sensor, wearable system
