Rehabilitation Support System Using Visual Activity Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rehabilitation support systems fail to maintain or improve motivation among users, particularly those with relatively small physical activity levels, as they lack effective feedback mechanisms to compare their efforts with others, leading to differing motivational effects.
Innovation Solution
A rehabilitation support system that acquires sensor data to calculate and display cumulative activity values over set periods, using image items to visually represent individual and comparative rehabilitation efforts on a shared display screen, allowing users to track their progress and relative efforts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual feedback of rehabilitation achievement level is provided to each user, then the user's motivation for rehabilitation is increased, but the motivational effect differs for each user and overall motivation cannot be maintained
Solution Approach 1:
The system implements a feedback mechanism that displays cumulative activity amounts of multiple users on a shared display screen. This allows users to see their own progress relative to others, creating a social comparison feedback loop that maintains motivation for all users rather than just providing individual achievement feedback.
Solution Approach 2:
The patent merges individual feedback with group feedback by displaying both individual cumulative activity amounts and comparative information on a shared display screen. This combination allows users to receive personalized progress tracking while also benefiting from social comparison with peers, resolving the contradiction between individual motivation and overall group motivation.
2Productivity
If feedback is provided only to users with large physical activity amount, then their motivation is enhanced, but users with small activity amount do not receive sufficient motivation
Solution Approach 1:
The system creates equipotentiality in motivational opportunities by providing the same visual feedback interface to all users regardless of their activity level. Each user sees their own cumulative activity amount displayed alongside others, allowing users with small activity amounts to visualize their progress and be motivated to increase it, rather than receiving no feedback at all.
Solution Approach 2:
The display screen uses visual representation (image items) that change based on cumulative activity amounts. This visual feedback mechanism provides intuitive, easy-to-understand information to all users, making the system easy to operate and understand while effectively motivating users across all activity levels.
3Loss of information
If users can only know their own effort, then individual progress tracking is simple, but relative effort comparison with others is unavailable and overall motivation cannot be improved
Solution Approach 1:
The shared display screen acts as an intermediary that processes and presents cumulative activity amount information for multiple users. It collects data from various users, processes it into comparable visual representations, and displays it in a way that allows easy comparison while maintaining individual privacy. This intermediary resolves the contradiction by providing relative effort information without requiring complex individual tracking systems.
Data Source
AI summary
A rehabilitation support system includes a data acquisition unit that acquires sensor data including biological information, an activity amount calculation unit that calculates an activity amount accompanying activity of user, based on the acquired sensor data, a cumulative value calculation unit that calculates the cumulative value of the activity amount of the user in the set period, a display processing unit that generates an image item corresponding to the cumulative value, and a second display unit that displays the image item generated by the display processing unit on the display screen, and a plurality of the set periods are included in the period of activity of the user.
