3D Work Support System for Viewpoint and Hand Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work support systems are limited by the field of view of the supporter, either through the imaging range of peripheral devices or the field of view of the worker, restricting the ability to perform viewpoint shifts and hand motions effectively.
Innovation Solution
A work support system incorporating a display device, motion sensors, and an arithmetic apparatus that identifies and processes hand motions and spatial shifts to enable viewpoint changes and work support using a 3D coordinate space, allowing for both viewpoint shifts and hand motions to be executed by a user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an image of the field of view of the worker is provided to the supporter, then the supporter can see what the worker sees, but the field of view of the supporter is limited to the field of view of the worker
Solution Approach 1:
The patent transitions from a 2D image display to a 3D coordinate space representation. The arithmetic apparatus displays a 3D work-target object in a 3D coordinate space, allowing the supporter to view the work scene from multiple perspectives and positions, thereby expanding the field of view beyond the worker's limited viewpoint.
Solution Approach 2:
The patent introduces a 3D coordinate space as an intermediary between the worker's field of view and the supporter's viewpoint. This intermediate representation allows the supporter to access and navigate the work environment from different positions, overcoming the limitation of being constrained to the worker's fixed perspective.
2Ease of operation
If an image of the peripheral imaging apparatus is scrolled based on the movement of the administrator, then the viewpoint of the administrator can be shifted, but the field of view is still limited to the imaging range of the peripheral imaging apparatus
Solution Approach 1:
The patent uses a 3D coordinate space to represent the work environment, allowing the administrator to navigate and view the work scene from multiple positions and perspectives. This three-dimensional representation enables unlimited viewpoint shifts within the 3D space, overcoming the two-dimensional imaging range limitations of traditional peripheral cameras.
Solution Approach 2:
The 3D coordinate space serves multiple functions: it represents the work environment, enables viewpoint navigation, and provides hand motion recognition for work guidance. This multi-functional approach eliminates the need for separate imaging systems for different purposes, thereby expanding the effective imaging range beyond the physical constraints of peripheral cameras.
3Ease of operation
If hand motion of the experienced person is superimposed on an image of the field of view, then work support using hand motion is possible, but the field of view is limited to the worker's field of view
Solution Approach 1:
The patent displays the 3D work-target object in a 3D coordinate space rather than superimposing hand motion on a 2D image. This three-dimensional display allows the hand motion to be represented accurately in 3D space while simultaneously providing an expanded field of view, resolving the contradiction between hand motion work support and field of view limitations.
Solution Approach 2:
The patent merges the 3D representation of the work-target object with the hand motion information in the same 3D coordinate space. This integration allows the supporter to view both the work environment and the hand motion guidance simultaneously from any viewpoint, combining work support functionality with an expanded field of view.

AI summary
An arithmetic apparatus displays a 3D work-target object in a 3D coordinate space on a display device, and receives a motion signal that is a signal representing a motion measured by any one of sensor units. When receiving the motion signal, the arithmetic apparatus identifies the measured motion based on the motion signal. When the identified motion is a motion regarding a spatial shift that is a shift of a viewpoint in the 3D coordinate space of a user, the arithmetic apparatus shifts the viewpoint in the 3D coordinate space of the user in accordance with the identified motion. When the identified motion is a hand motion regarding a work movement with respect to a work target, the arithmetic apparatus outputs output information including information representing the work movement in accordance with the identified motion.
