Summary
This study introduces an electromyography (EMG) controller for accessible gaming, enhancing limb-difference accessibility. Biofeedback training improved user performance and satisfaction in a serious game designed for prosthetic arm integration.
Area of Science:
- Rehabilitation Engineering
- Human-Computer Interaction
- Biofeedback Systems
Background:
- Limb-difference presents accessibility challenges in conventional video gaming.
- Electromyography (EMG) sensors offer a potential control method for adaptive interfaces.
- Biofeedback serious games can facilitate motor skill training and prosthetic control.
Purpose of the Study:
- To evaluate a novel EMG-based video game controller for limb-difference accessibility.
- To assess the effectiveness of a biofeedback training platform integrated with a serious game.
- To determine user satisfaction and usability of the developed system.
Main Methods:
- Developed an EMG sensor-based video game controller and a corresponding biofeedback training platform.
- Recruited 50 college-aged students, divided into two cohorts with different training interventions (free play vs. challenge mode).
- Collected data on performance (time on task) and user experience (satisfaction, usability) through pre-test and post-test assessments.
Main Results:
- Participants demonstrated improved performance, indicated by increased success rates within a given time on task.
- The biofeedback training intervention positively impacted user ability and task success.
- User satisfaction and system usability were evaluated, providing insights into participant experience.
Conclusions:
- The EMG-controlled accessible video game controller and training platform show promise for enhancing gaming accessibility for individuals with limb differences.
- The biofeedback system effectively translates muscle contractions into gameplay actions, aiding in skill acquisition.
- The study validates the training methods and highlights the potential for integrating such technologies with prosthetic devices.
