Work Assistance System Spatial Positioning via Extracted Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work assistance systems face challenges in minimizing data capacity during video communication and ensuring accurate perception of instruction positions, particularly when workers move without checking the work instruction video.
Innovation Solution
A work assistance system that includes an image capturing unit, a virtual object generation unit, and a communication system to transmit image capturing position data and instruction reference position data, allowing the first user to accurately perceive the instruction position through a work assistance virtual object displayed in real-time, even when moving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data communication is performed between worker side computer and instructor side computer, then the instructor can give work instructions while watching the work video, but the data communication requires a long time due to large data capacity
Solution Approach 1:
The patent extracts only the essential information from video data - specifically image capturing position data and instruction position data - and transmits these as separate data streams. This separates the critical spatial information from the bulky video data, enabling fast transmission of instruction positions while the full video can be transmitted separately or not at all.
Solution Approach 2:
The patent creates simplified data representations (copies) of the video information - specifically extracting key positional data points from the video streams. These copied position data elements serve as lightweight proxies for the full video content, allowing rapid communication of instruction locations without transmitting the entire video.
2Ease of operation
If the worker checks the work instruction video at the current location of the movement destination, then the worker can access the instruction, but it is difficult to accurately perceive the position of the work instruction shown in the video
Solution Approach 1:
The patent introduces image capturing position data as an intermediary that links the video content to the physical workspace. This intermediary data enables the worker's device to understand the spatial relationship between the video frame and the actual work environment, allowing accurate positioning of instructional overlays even when the worker moves to different locations.
Solution Approach 2:
The patent adds a spatial dimension to the video instruction system by incorporating position data coordinates. This transforms the instruction delivery from a purely visual 2D video experience to a 3D spatially-aware system where instruction positions are accurately mapped to physical locations in the workspace, enabling precise perception regardless of worker movement.

AI summary
A work assistance system includes a first system used by a first user, and a second system used by a second user who gives an instruction about work in a space where the first user is present. The second system includes: a second display unit that displays an image in the space captured by the first system; a data generation unit that generates instruction reference position data indicating an instruction reference position corresponding to image capturing position data and instruction position data indicating an instruction position based on an operation of designating the instruction position on the image; and a second communication unit that outputs the instruction reference position data and the instruction position data. The virtual object generation unit generates a work assistance virtual object based on the instruction reference position data and the instruction position data.
