Virtual Body Feedback for Abnormal Joint Motion Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack an index to determine when a user should perform or refrain from specific actions, and there is a need to visualize and address abnormal joint movements during rehabilitation to improve cognitive and exercise abilities.
Innovation Solution
An information processing system that makes a user's body or its parts invisible, requests specific actions, and controls the difficulty of these actions by visualizing abnormal joint movements through articular linkages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the user is provided with visual feedback of their body movements, then the user can understand their action status, but the abnormal joint movements (articular linkages) cannot be effectively visualized
Solution Approach 1:
The system creates a virtual copy of the user's body and joint movements in the virtual space. This virtual body serves as a visual representation that can display abnormal joint movements without obscuring the user's actual body visibility. The virtual body copy allows simultaneous visualization of both normal body actions and abnormal joint movements through separate visual channels.
Solution Approach 2:
The system transitions the visualization of joint movements from the physical space to the virtual space, adding a new dimensional layer for information display. By projecting joint movement data onto virtual bodies in a virtual environment, the system enables simultaneous visualization of body actions and abnormal joint movements without spatial interference.
2Loss of information
If the system provides detailed feedback on joint movements, then the cognitive ability can be improved, but the complexity of the system increases
Solution Approach 1:
The virtual body in the virtual space serves multiple functions simultaneously: it represents the user's body position, displays joint movement information, provides visual feedback for rehabilitation, and indicates abnormal movements. This multi-functional design reduces the need for separate systems for each function, thereby reducing overall system complexity while providing comprehensive feedback.
3Productivity
If the user performs body actions in a natural environment, then the exercise ability can be improved, but the abnormal actions of joints cannot be visualized
Solution Approach 1:
The virtual body acts as an intermediary between the user's physical joint movements and the visual feedback system. It translates complex joint movement data into intuitive visual representations that can be displayed in the virtual space, enabling the visualization of abnormal joint actions during natural exercise without interfering with the exercise itself.

AI summary
This invention effectively improves the cognitive ability or the exercise ability of a user. An information processing system includes a blocker that makes whole or a part of a body of a user invisible, a requester that requests the user to perform a body action that makes a part of the body of the user or an object operated by the user overlap a target object, and a controller that controls, under an environment which is generated by the blocker and the requester and in which an abnormal action of a joint is visualized, difficulty of the body action in accordance with a motion of a joint part different from a body that performs the body action.
