Real-time Self-Visualization System for Motor Activity Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Humans are poor at visualizing their body movements kinesthetically, making it difficult to learn or practice motor skills effectively, as existing techniques lack real-time feedback during natural motion.
Innovation Solution
A system comprising a camera, computer, and display that captures and augments images of a user's motor activity with real-time static and dynamic visual cues, allowing for self-visualization and feedback during performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If post-performance assessment methods like video analysis are used, then motor skill learning can be supported, but the feedback is delayed beyond the brief human short-term kinesthetic memory
Solution Approach 1:
The system implements real-time feedback by capturing images during motor activity performance, processing them through a computer, and displaying augmented images with visual cues immediately to the user. This continuous feedback loop occurs within the brief window of short-term kinesthetic memory, allowing users to adjust their movements based on immediate visual information rather than delayed post-performance analysis.
Solution Approach 2:
The system prepares visual feedback in advance by pre-configuring target references and augmentation parameters before the motor activity begins. The computer is pre-programmed with the motor activity parameters and visual cue configurations, so that when the user performs the activity, the feedback is already ready to be displayed in real-time without processing delays.
2Reliability
If real-time image processing and augmentation are implemented, then immediate feedback is provided, but system complexity increases
Solution Approach 1:
The computer serves multiple functions: it captures images from the camera, processes the images to generate augmentations, stores motor activity parameters, manages display output, and handles user interactions. By consolidating these diverse functions into a single computing platform, the system achieves real-time feedback capability without proportionally increasing overall system complexity.
Solution Approach 2:
The display acts as an intermediary device that receives processed images and visual cues from the computer and presents them to the user in real-time. This intermediary layer simplifies the interface between the complex image processing system and the user, allowing the sophisticated real-time feedback processing to occur behind the scenes while maintaining a relatively simple user-facing display component.

AI summary
The present disclosure relates to a system which may allow a user to visualize and/or monitor motor activities during, e.g., rehabilitation exercises and/or athletic training. The system may include a camera that may be configured to capture images of a user performing a motor activity. The system may also include a computer configured to receive the captured images from the camera while the user is performing the motor activity. The computer may be further configured to provide static and dynamic augmentation of the captured images. The system may further include a display for the user. The display may be configured to receive the augmented captured images from the computer and to display the augmented captured images to the user.
