Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality (VR) medical training simulations face challenges in maintaining user engagement due to repetitiveness and inaccurate assessment of user expertise, leading to unsatisfactory experiences for both unskilled and advanced trainees, as well as difficulties in distinguishing between mistakes and valuable alternatives in user interactions.
Innovation Solution
A computer-implemented method that assigns an initial competence level to users, acquires and evaluates their actions during training, determines deviations from expected actions, calculates a performance index, and modifies the training pathway based on user performance and expertise level to optimize the training experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the VR simulation follows a fixed expected pathway for all users, then the training structure is simple and easy to implement, but the user engagement decreases due to repetitiveness and the training durability is reduced
Solution Approach 1:
The training pathway is transformed from a static fixed sequence to a dynamic adaptive structure that automatically adjusts based on user performance metrics. The system modifies the expected pathway in real-time by adding, removing, or modifying actions based on the user's competence level and performance index, thereby maintaining user engagement while preserving structural organization through algorithmic adaptation rather than manual redesign
2Device complexity
If the VR simulation uses a single fixed expected pathway, then the system complexity is low, but it cannot accurately adapt to different user expertise levels and provides unsatisfactory training experiences
Solution Approach 1:
The system adjusts training parameters including the sequence of actions, complexity levels, and guidance intensity based on measured user performance metrics. By dynamically changing these parameters according to the user's competence level and performance index, the system achieves high adaptability without requiring multiple complete training programs, thus maintaining relatively low system complexity while providing personalized training experiences
3Device complexity
If the VR simulation treats all deviations from expected actions as mistakes, then the evaluation criteria are simple, but it fails to recognize valuable alternatives proposed by proficient users and reduces learning effectiveness
Solution Approach 1:
The system implements a multi-level feedback mechanism that evaluates deviations contextually based on user competence level and performance history. Instead of uniformly penalizing all deviations, the system provides differentiated feedback that recognizes alternative approaches from proficient users, transforms valuable deviations into updated training content, and maintains simple evaluation rules while achieving precise and nuanced assessment through adaptive feedback strategies

AI summary
A computer implemented method for optimizing a medical training procedure is disclosed using virtual reality and/or augmented reality on a virtual patient in a virtual or real operating room. The method includes assigning an initial specific competence level to the user before the training procedure, acquiring action data indicative of the virtual actions performed by the user, determining the presence of a deviated action, determining a final performance index of the user, and modifying or confirming the expected pathway of the training procedure based on the initial competence level of the user and the final performance index, and updating the expected pathway stored in the database if the expected pathway is modified.
