Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stroke recovery processes, particularly for ischemic strokes, are arduous and often discouraging, leading to low participation in physical therapy due to the challenging nature of rebuilding mobility and cognition.
Innovation Solution
A system incorporating wearable sensors and a processor to create a virtual reality environment with virtual characters that interact with users, providing therapeutic activities and feedback to encourage and monitor progress in physical therapy, including games and exercises that promote correct posture, balance, and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional physical therapy is used for stroke recovery, then therapeutic treatment is provided, but user engagement and motivation are low due to the arduous and discouraging nature of recovery
Solution Approach 1:
The patent introduces virtual characters as intermediaries between the user and the therapy system. These virtual characters provide encouragement, praise, and emotional support, making the therapy experience more engaging and less daunting. The virtual characters act as a mediator that translates complex therapeutic requirements into friendly, motivating interactions.
Solution Approach 2:
The patent transitions from traditional two-dimensional therapy instruction to immersive three-dimensional virtual reality environment. Users wear VR headsets and interact with virtual characters in a 360-degree environment, adding spatial and interactive dimensions to therapy that significantly boost engagement and motivation.
2Productivity
If virtual reality environment with virtual characters is implemented, then user engagement and motivation are enhanced, but system complexity and cost increase
Solution Approach 1:
The virtual characters serve multiple functions simultaneously: they provide therapeutic instruction, monitor user performance, offer encouragement and praise, track progress, and create an immersive environment. This multi-functionality consolidates what would otherwise require separate systems into a single integrated solution.
Solution Approach 2:
The system implements continuous feedback loops where virtual characters provide real-time verbal encouragement, praise, and performance feedback. The system tracks user movements through sensors and immediately responds with appropriate feedback, creating a dynamic interaction that enhances therapy effectiveness while managing system complexity through intelligent software control.
3Reliability
If immediate feedback and virtual character interaction are provided, then user motivation increases, but processing requirements and computational load increase
Solution Approach 1:
The virtual characters and their dialogue scripts are pre-programmed with various encouragement phrases, praise patterns, and interaction responses. The system prepares multiple feedback options in advance and selects appropriate pre-defined responses based on user performance, reducing real-time computational requirements while maintaining consistent and reliable therapy delivery.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances user engagement and motivation in physical therapy by providing immediate and long-term feedback, encouraging participation and progress in stroke recovery by making the rehabilitation process more immersive and rewarding.
Implementation Method 1
one or a plurality of wearable sensors configured to be disposed at varying positions on a user, wherein a real-world motion of the user is tracked by the one or a plurality of wearable sensors
Implementation Method 2
at least one of the sensors includes an emitter, wherein the emitter and the at least one sensor are configured to track movements of the user
Data Source
AI summary
A system and method for facilitating physical therapy that may include a wearable display, wearable sensors disposed at varying positions on a user, a processor comprising executable instructions configured to provide a virtual reality environment, virtual characters, and therapeutic activities on the wearable display, wherein the virtual characters interact with the user to provide at least form feedback and positive reinforcement. A new instance of the virtual reality environment, with identifiable differences, may be generated in response to a measured completion or partial completion of a therapeutic activity. Changes in the virtual reality environment may offer users continued indications of progression throughout the duration of a physical therapy program. The system may include a connectable device comprising a display that duplicates a portion of the wearable displays image, enables interaction within the virtual reality environment, and allows for the selection and modification of therapeutic activities.
