Toward gesture controlled wheelchair: a proof of concept study
Summary
This study introduces a new gesture-based wheelchair control system. Users can steer the wheelchair using arm movements, enabling hands-free operation for tasks like cooking.
Area of Science:
- Robotics
- Human-Computer Interaction
- Assistive Technology
Background:
- Traditional wheelchairs limit users' ability to perform tasks requiring free hands.
- Existing control methods may not fully support multitasking for individuals with mobility impairments.
Purpose of the Study:
- To develop and test an interactive, gesture-based wheelchair control system.
- To enable users to control wheelchair direction using arm positions while holding objects.
Main Methods:
- An image sensor captures user arm positions.
- An image-recognition algorithm processes sensor data.
- Arm position data is translated into wheelchair steering signals.
Main Results:
- A prototype wheelchair control system was developed.
- Initial experiments demonstrated feasibility of arm-based control.
- The system allows simultaneous wheelchair operation and object manipulation.
Conclusions:
- Gesture-based wheelchair control using arm movements is a viable concept.
- This technology can enhance independence for users in daily activities.
- Further development can improve functionality for complex tasks.
