    Area of Science:

    • Assistive Technology
    • Human-Computer Interaction
    • Biomedical Engineering

    Background:

    • Traditional keyboards present significant challenges for individuals with severe motor impairments.
    • Head and mouth stick users often face difficulties with simultaneous key presses, accidental strikes, and repeated key actuations.

    Purpose of the Study:

    • To design and construct a novel keyboard specifically for users relying on head or mouth sticks.
    • To address the limitations of existing assistive input devices by introducing a new actuation concept.

    Main Methods:

    • Development of a completely new keyboard concept, termed the 2DOF keyboard.
    • Implementation of a design requiring only two degrees of freedom for key actuation.
    • Ensuring the keyboard is transparent to the connected personal computer for software compatibility.

    Main Results:

    • The 2DOF keyboard successfully addresses issues of simultaneous key requirements.
    • Accidental key strikes and multiple strikes of the same key are effectively mitigated.
    • The device functions seamlessly with standard personal computer software.

    Conclusions:

    • The 2DOF keyboard offers a groundbreaking solution for computer access for individuals with specific physical limitations.
    • This new assistive keyboard technology enhances usability and overcomes critical barriers in human-computer interaction.
