AI Technical Summary

Technical Problem

Existing technologies struggle to effectively capture the precise movements required for cable jointing tasks, particularly scraping the outer semiconductive layer of CV cables, due to the difficulty in accurately measuring hand movements and tool interactions, which are crucial for acquiring the necessary skills.

Method used

A sensor set comprising a pressure sensor and an acceleration sensor is worn on the hand to measure finger pressure and hand acceleration, combined with a mobile PC for real-time evaluation and comparison with expert data to provide feedback on the trainee's movements.

Benefits of technology

This system enables accurate detection and evaluation of delicate hand movements during cable jointing tasks, facilitating skill acquisition by providing real-time feedback and improving the quality of the scraping process.

Abstract

To support learning of skill of work in need of prescribed operation including movement of a hand in a state where an object is pressurized by a finger.SOLUTION: A sensor set is prepared including a pressure sensor for measuring pressure applied by a finger and an acceleration sensor for measuring acceleration of a hand for a first worker who performs work requiring predetermined action. A computer detects operation based on sensing data including pressure and acceleration measured by the sensor set. In order to evaluate the first worker, the computer compares first operation information, which is operation information obtained from the sensing data of the first worker, with second operation information with respect to the detected operation.SELECTED DRAWING: Figure 4
