Summary
This study introduces adaptive difficulty for robotic rehabilitation games, balancing user motivation and performance. Initial tests suggest personalized game parameters improve motor planning engagement.
Area of Science:
- Robotics
- Rehabilitation Medicine
- Human-Computer Interaction
Background:
- Robotic rehabilitation games require adaptive difficulty to maintain user engagement.
- Motor planning is crucial for effective rehabilitation outcomes.
- Balancing user motivation and performance is key to successful therapy.
Purpose of the Study:
- To develop and evaluate a strategy for adapting game difficulty in robotic rehabilitation.
- To integrate user motivation and performance metrics for adaptive control.
- To explore the individualization of game parameters for enhanced user experience.
Main Methods:
- A Pong game was used as a platform for motor planning rehabilitation.
- User motivation was classified into three levels: not motivated, well motivated, and overloaded.
- User performance was assessed using knowledge of results (goals, score) and knowledge of performance (joint displacement, speed, aiming, work).
Main Results:
- Initial pilot tests were conducted with unimpaired healthy young volunteers.
- Results indicate a tendency towards individualizing adaptive parameter values.
- The strategy showed potential for tailoring game difficulty to user state.
Conclusions:
- Adaptive difficulty strategies can enhance engagement in robotic rehabilitation games.
- Integrating motivation and performance data allows for personalized rehabilitation.
- Further research with patient populations is warranted to validate these findings.
