Design of novel non-contact multimedia controller for disability by using visual stimulus

Area of Science:

• Biomedical Engineering
• Human-Computer Interaction
• Neuroscience

Background:

• Conventional multimedia controllers require manual operation, posing challenges for disabled individuals.
• Existing assistive technologies may lack intuitive control or require external assistance.
• There is a need for non-contact control solutions to improve accessibility for patients with limited mobility.

Purpose of the Study:

• To design and validate a novel non-contact multimedia controller.
• To enable disabled patients to control multimedia systems using visual stimuli and electroencephalogram (EEG) signals.
• To develop a wearable and wireless EEG acquisition device for seamless monitoring.

Main Methods:

• A system utilizing visual stimuli presented on a commercial tablet to control multimedia functions.
• Integration of a wearable, wireless electroencephalogram (EEG) acquisition device.
• Experimental validation of the system's ability to measure and extract EEG features related to visual stimuli.

Main Results:

• The proposed system effectively measures and extracts EEG features correlated with visual stimuli.
• The non-contact controller demonstrated a good information transfer rate.
• Experimental results validate the system's functionality and effectiveness.

Conclusions:

• The developed non-contact multimedia controller offers a novel and accessible control scheme.
• The system empowers disabled patients by enabling independent multimedia operation.
• This technology serves as a promising prototype for future assistive control systems.
