ZigBee-based wireless intra-oral control system for quadriplegic patients.

Area of Science:

• Biomedical Engineering
• Human-Computer Interaction
• Assistive Technology

Background:

• Patients with severe motor impairments, such as those from stroke or spinal cord injury, often face significant challenges in controlling external devices.
• Existing assistive technologies may be costly, power-intensive, or lack seamless integration for comprehensive environmental control.

Purpose of the Study:

• To develop and present a novel wireless human-to-computer interface system controlled by tongue movements.
• To leverage the ZigBee protocol for reliable, low-power, and cost-effective communication within the system.
• To enhance the quality of life for individuals with limited mobility by providing intuitive control over various devices.

Main Methods:

• The system comprises a wireless intra-oral module with five buttons, a wireless coordinator, and distributed wireless controllers.
• The ZigBee protocol was implemented to ensure robust and energy-efficient wireless data transmission.
• User interaction is facilitated by manipulating the intra-oral module buttons with the tongue.

Main Results:

• The developed system enables users to control computer cursors, menus, wheelchairs, lights, televisions, phones, and robotic devices.
• The ZigBee protocol demonstrated reliable and low-power communication, crucial for an intra-oral device.
• The system offers a cost-efficient solution for assistive control.

Conclusions:

• The presented tongue-controlled wireless system offers a viable and effective assistive technology for individuals with stroke and spinal cord injuries.
• This innovation has the potential to significantly improve patient autonomy and quality of life.
• The use of the ZigBee protocol makes the system accessible and practical for widespread adoption.
