Skill Index Calculation for Adaptive Operator Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operator interface technologies struggle to accurately estimate user proficiency based on operation logs, as the time interval for key operations does not necessarily reflect proficiency, leading to potential errors and inefficiencies in input and output operations.
Innovation Solution
A skill index provision device that calculates a skill index for users based on their operation logs, incorporating factors such as the accuracy and speed of key operations, and uses this index to provide adaptive interfaces that enhance operator efficiency and accuracy.

Engineering Contradiction Analysis
1Device complexity
If the time interval for key operation is used to judge operator proficiency, then the estimation process is simple, but the accuracy of proficiency estimation deteriorates
Solution Approach 1:
The patent changes the parameters used for proficiency estimation from simple time interval to a composite index incorporating multiple parameters: key operation accuracy rate and dispersion values of operation speed. This transforms the estimation from a single-dimension metric to a multi-dimensional skill index that accurately reflects operator proficiency across different task aspects.
Solution Approach 2:
The skill index is constructed as a composite measure combining multiple operational parameters (accuracy rate, speed dispersion) similar to how composite materials combine different properties. This composite approach allows the system to capture the nuanced reality of operator proficiency that cannot be represented by a single parameter like time interval alone.
2Device complexity
If operator proficiency is not accurately estimated, then the interface remains simple, but the work task efficiency deteriorates
Solution Approach 1:
The interface dynamically adapts its complexity and functionality based on the calculated skill index. For operators with higher proficiency scores, the system provides more advanced features and less guidance, while for lower proficiency operators, it offers more support and simplified interactions. This dynamic adjustment optimizes work task efficiency by matching interface complexity to individual operator capabilities.
Solution Approach 2:
The system applies different levels of interface support and complexity to different operators based on their individual skill indices. Rather than using a uniform interface for all users, the system tailors the interface quality and features locally to each operator's demonstrated proficiency level, thereby optimizing efficiency for each user.
