    Area of Science:

    • Biomedical Engineering
    • Assistive Technology
    • Rehabilitation Engineering

    Background:

    • Individuals with quadriplegia often face challenges in independently controlling their environment.
    • Existing environmental control systems can be expensive and complex.

    Purpose of the Study:

    • To develop and describe a low-cost, user-friendly environmental control system for quadriplegics.
    • To enable independent operation of electrical devices using a single input switch.

    Main Methods:

    • Design of a custom input switch.
    • Integration of the switch with control circuitry for electrical devices.
    • System construction and cost analysis.

    Main Results:

    • A functional environmental control system was developed.
    • The system allows control of up to three electrical devices via a single switch.
    • The system can be built in approximately one day for around $40 in parts.

    Conclusions:

    • The described system offers a cost-effective solution for environmental control for quadriplegics.
    • The design is scalable to accommodate more devices.
    • This technology can significantly improve the quality of life and independence for users.
