Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack effective methods to provide immersive and personalized virtual environments for individuals with autism spectrum disorder (ASD) and other sensory overload conditions, failing to adapt simulation intensity to individual sensory thresholds, which hinders the development of executive functions and social-emotional skills.
Innovation Solution
A system utilizing sensors and machine learning to create a customizable, adaptive virtual environment with computer-generated avatars that adjust sensory variables such as visual and audio inputs based on real-time physiological data, allowing for controlled practice of executive functions without overstimulation or under-challenge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If immersive virtual environment simulation is provided for individuals with ASD, then executive function skills development is improved, but sensory overload and anxiety increase
Solution Approach 1:
The system dynamically adjusts simulation complexity and sensory variables in real-time based on physiological sensor data. The virtual environment transitions from static to adaptive, modulating visual, auditory, and interactive elements according to the user's current anxiety and engagement levels, resolving the contradiction between providing sufficient stimulation for skill development and avoiding sensory overload
Solution Approach 2:
The system changes multiple parameters of the virtual environment simultaneously including visual complexity, audio intensity, avatar behavior, and task difficulty based on physiological feedback. This coordinated parameter adjustment allows the system to optimize the balance between therapeutic challenge and sensory comfort, improving executive function skills while preventing anxiety-induced shutdown
2Ease of manufacture
If standardized virtual environment is used, then implementation is simplified, but individual sensory thresholds and needs are not met
Solution Approach 1:
The system automatically adapts to individual users through real-time physiological monitoring and AI-driven adjustments without requiring manual customization for each user. The sensors continuously feed data to the control system, which self-adjusts the virtual environment parameters, eliminating the need for complex manual setup while providing personalized adaptation
Solution Approach 2:
The system implements closed-loop feedback by continuously monitoring physiological data (heart rate, galvanic skin response, etc.) and using this information to adjust the virtual environment in real-time. This feedback mechanism enables automatic personalization of the simulation to match each user's sensory thresholds and therapeutic needs
3Productivity
If high sensory stimulation is provided, then skill practice intensity is increased, but anxiety and sensory overload worsen
Solution Approach 1:
The system applies partial stimulation by selectively adjusting which sensory variables are modified based on current physiological state and therapeutic goals. Rather than uniformly increasing or decreasing all sensory inputs, the system makes targeted adjustments to specific parameters (visual complexity, audio levels, avatar interactions) to maintain optimal challenge without triggering anxiety
Solution Approach 2:
Real-time physiological feedback allows the system to continuously monitor anxiety indicators and adjust stimulation intensity accordingly. When sensors detect elevated anxiety markers, the system automatically reduces sensory load; when engagement is optimal, the system can safely increase practice intensity, creating a dynamic balance between challenge and comfort
4Object-affected harmful factors
If low sensory stimulation is provided, then anxiety is reduced, but skill development challenge is insufficient
Solution Approach 1:
The virtual environment dynamically transitions between low and high stimulation states based on real-time physiological data. The system can safely increase challenge when the user is calm and engaged, then reduce stimulation if anxiety rises, creating an adaptive rhythm that maintains both comfort and therapeutic effectiveness throughout the session
Data Source
AI summary
An adaptive computer simulation rendering system is disclosed for conditioning an individual having Autism Spectrum Disorder (ASD) to real-world environments through variable sensory output in computer simulations. The subject is fully or partially immersed in a computer-simulated environment for a time-limited session. Real-time monitoring of the human subject is performed for a change in a sensor-derived, quantified sensory load level. Responsive to an increase in sensory load level, the computer-simulated environment modulates the sensor load on the individual. The human subject adapts to increasingly complex environments by this modulation of simulation thereby providing therapeutic benefit to the individual with ASD.
