Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of virtual reality environments often overlook or ignore the need for regular breaks, leading to physiological stress, particularly for elderly and physically impaired users who struggle with interacting with virtual objects in three dimensions.
Innovation Solution
A computer-implemented method and system that detects parameters of user movement in response to interacting with virtual objects within a virtual reality environment to determine physiological stress, allowing for dynamic and targeted assessment and adaptation of the environment to reduce stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users are heavily immersed or engaged within a virtual environment, then user engagement and interaction capability are improved, but users are more likely to overlook or ignore the need for regular breaks, leading to physiological stress
Solution Approach 1:
The system continuously monitors user movement parameters (reaction time, movement speed, movement amplitude) and provides feedback by calculating physiological stress measures. This feedback mechanism allows the system to detect stress levels in real-time and can trigger interventions to remind users to take breaks, thereby resolving the contradiction between maintaining high engagement and preventing physiological stress.
Solution Approach 2:
The system automatically monitors user physiological stress through movement parameter analysis without requiring user input or awareness. The computer independently detects movement parameters, calculates stress measures, and can autonomously intervene to alert users, enabling the system to serve itself in monitoring and protecting user health while maintaining immersive engagement.
2Adaptability or versatility
If users interact with virtual objects in three dimensions at multiple angles and orientations, then interaction capability and versatility are improved, but difficulty and physiological stress increase for elderly and physically impaired users
Solution Approach 1:
The system changes the parameters of interaction by monitoring movement characteristics (reaction time, movement speed, movement amplitude) and adjusting the virtual environment accordingly. When physiological stress is detected, the system can modify interaction requirements, such as reducing the number of required movements or adjusting object positions, thereby maintaining versatility while reducing difficulty for elderly and physically impaired users.
Solution Approach 2:
The system dynamically adapts the virtual environment based on real-time physiological stress measurements. The computer can adjust interaction parameters, object locations, and task requirements on-the-fly, transforming a static interaction model into a dynamic one that responds to user capabilities and stress levels, thus maintaining high adaptability while reducing operational difficulty.

AI summary
Proposed are concepts of identifying physiological stress of a user of a virtual reality environment by displaying to the user a virtual object at an object location within the virtual reality environment and instructing the user to interact with the displayed virtual object. A measure of physiological stress may then be determined based on a detected parameter of the user's movement in response to the instruction, and the measure of physiological stress may be associated with a part of the user's body based on the object location.
