Wearable Work Instruction Display for Real-Time Motion Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques fail to inform workers of deviations from standard motions during work and struggle to effectively transfer skilled workers' skills to junior workers, especially in globalized settings where quality may deteriorate.
Innovation Solution
An information processing system that acquires standard and work data, determines differences, and generates instruction images for correction, displayed on a wearable device to guide workers in real-time, ensuring adherence to standard procedures and skill transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard work evaluation is performed based on registered standard data and workpiece state, then work quality can be maintained, but workers cannot be informed of deviations from standard motions to correct their work
Solution Approach 1:
The system captures images of the workpiece and worker's motions, compares them against standard data, and provides real-time feedback by displaying difference images and correction instructions on a wearable display device. This closed-loop feedback mechanism enables workers to immediately understand and correct deviations from standard procedures.
Solution Approach 2:
The system introduces an intermediary image processing and comparison mechanism that visually represents the difference between actual and standard work motions. The difference image serves as an intermediary that translates complex measurement data into intuitive visual feedback for the worker.
2Adaptability or versatility
If skilled workers' skills are transferred to junior workers through traditional methods, then skill传承 can occur, but the process is slow and quality may deteriorate in globalized settings
Solution Approach 1:
The system creates digital copies of skilled workers' standard motions and work methods, storing them as reference data. Junior workers can access and compare their work against these standardized copies, enabling consistent skill transfer across different locations and workers without requiring direct observation or prolonged apprenticeship.
Solution Approach 2:
The system prepares standard work data and correction instructions in advance, making them available for immediate comparison and learning. This preliminary preparation of reference materials accelerates the skill transfer process by eliminating the need for gradual, trial-and-error learning.

AI summary
The problem is solved by an information processing system including: a standard data acquirer that acquires registered standard data on work; a work data acquirer that acquires work data on a worker performing the work; a determiner that determines whether or not a difference between the standard data acquired by the standard data acquirer and the work data acquired by the work data acquirer is a threshold value or more; a generator that generates an instruction image regarding correction of the work according to the difference when the difference is determined to be the threshold value or more by the determiner; and a displayer that displays the instruction image generated by the generator on a display unit of a display device worn by the worker to display the instruction image superimposed on a real space.
