Remote Assistance Display Zoom for Worker Camera Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Workers at a work site may struggle to recognize which part of the site a camera is capturing when receiving remote assistance, making it difficult to follow instructions accurately.
Innovation Solution
An information processing method that includes acquiring a moving image from a camera, receiving assistance information, displaying both on a screen, and enlarging the image when the worker's motion exceeds a threshold, allowing better recognition of the captured area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the worker displays the moving image at normal size during remote assistance, then the display interface is simple and easy to operate, but the worker cannot recognize which part of the work site the camera is capturing
Solution Approach 1:
The patent applies dynamics by making the display size of the moving image variable rather than fixed. The display interface automatically adjusts between normal size and enlarged size based on the worker's head motion detected by the sensor. When the worker's head moves beyond a predetermined range, the system enlarges the moving image display to help recognition, and returns to normal size when the head stabilizes. This dynamic adjustment resolves the contradiction by providing simplicity during normal viewing and enhanced recognition when needed.
2Loss of information
If the system continuously enlarges the moving image to improve recognition, then the worker can always see the captured portion clearly, but the display occupies excessive screen space and reduces visibility of other information
Solution Approach 1:
The patent implements periodic action through the head motion detection mechanism. The system continuously monitors the worker's head position via sensor and periodically adjusts the display size based on whether the head moves beyond the predetermined range. When the head stabilizes within the range, the display returns to normal size, allowing other information to become visible again. This periodic switching between enlarged and normal display modes resolves the contradiction by providing clear recognition only when needed, rather than continuously occupying screen space.

AI summary
A work terminal acquires a moving image captured at a work site from a camera, receives assistance information required for assisting work performed by a worker at the work site, from an assistance terminal used by an assisting person who assists the work, displays the received assistance information and the acquired moving image on a display part, acquires an amount of change in the motion of the worker from the sensor, and, if the amount of change is greater than or equal to a threshold value, enlarges the moving image being displayed.
