Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AR content display technologies are inefficient as they do not account for the operator's skill level, leading to increased time in performing operations and learning skills.
Innovation Solution
An AR content display device that includes an operation information generator, skill calculator, augmented reality marker determiner, and outputter, which assesses the operator's skill level by comparing their actions to those of a model operator and adjusts the AR content displayed accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If AR content is displayed independently of operator skill level, then the system is simple to operate, but the time taken to perform operations and learn skills increases
Solution Approach 1:
The AR content display system dynamically adjusts the type and amount of content displayed based on the operator's skill level. The skill level is calculated by comparing the operator's actions with model operator actions, and the system automatically modifies AR content delivery accordingly. This dynamic adaptation resolves the contradiction by making the system both simple to operate (automatic adjustment) and time-efficient (optimized content for skill level).
Solution Approach 2:
The system changes the parameters of AR content display based on the calculated skill level. For operators with lower skill levels, more detailed guidance and instructional content are displayed. For higher skill levels, less intrusive and more concise information is provided. This parameter adjustment resolves the contradiction by optimizing both operational simplicity and learning efficiency.
2Productivity
If AR content is customized based on operator skill level, then the efficiency of performing operations and learning skills improves, but the device complexity increases
Solution Approach 1:
The system performs self-service by automatically calculating the operator's skill level through comparison with model operations and autonomously selecting appropriate AR content without requiring manual intervention or complex configuration. This self-service mechanism resolves the contradiction by achieving high productivity through automated skill-based adaptation while keeping the system relatively simple in operation.
Solution Approach 2:
The system implements feedback by continuously monitoring operator actions, comparing them with model operations, and using this feedback to adjust AR content delivery in real-time. This closed-loop feedback mechanism enables the system to adapt to skill levels dynamically, improving productivity while managing complexity through automated feedback processing rather than complex manual control systems.
3Reliability
If detailed AR content is displayed for all operators, then skill training completeness is ensured, but the time taken to perform operations increases
Solution Approach 1:
The system applies local quality by providing different levels of AR content detail to different operators based on their skill levels. Rather than uniformly displaying detailed content for all operators, the system locally adapts the content quality to match individual needs. This resolves the contradiction by ensuring complete training for those who need it while allowing faster operations for those who have already mastered the skills.
Solution Approach 2:
The system applies partial action by displaying only the necessary amount of AR content for each operator's current skill level. For experienced operators, minimal AR content is displayed, while for beginners, more comprehensive content is provided. This partial application of content based on need resolves the contradiction between training completeness and operational speed.
