This study presents two computer-based communication programs for patients unable to speak or write. These affordable, user-friendly systems utilize alphabet or Morse code, offering vital communication support for individuals with severe physical impairments.

Area of Science:

  • Assistive Technology
  • Rehabilitation Medicine
  • Augmentative and Alternative Communication (AAC)

Background:

  • Numerous medical conditions (e.g., stroke, cancer surgery, trauma) can cause speechlessness and impair manual dexterity.
  • This communication impairment leads to patient frustration, isolation, and hinders therapeutic progress.
  • Existing communication methods may be insufficient for patients with both speech and motor deficits.

Purpose of the Study:

  • To introduce two novel, low-cost computer-based communication programs for nonverbal patients.
  • To provide an accessible and adaptable communication solution for individuals with severe physical limitations.
  • To improve patient-provider and patient-family communication in clinical settings.

Main Methods:

  • Development of two distinct communication programs utilizing a Commodore 64 computer.

Related Experiment Videos

  • One program employs an alphabet-based interface for communication.
  • The second program is based on the international Morse code system.
  • Both programs are designed for ease of use and compatibility with various switching devices.

    • Main Results:

    • The described programs offer a functional means of communication for severely impaired patients.
    • The systems are inexpensive and simple to implement in diverse healthcare environments.
    • Adaptability to different switching devices ensures broad applicability.

    Conclusions:

    • Computer-based communication programs can effectively address the needs of speechless patients with motor impairments.
    • These AAC solutions enhance patient engagement and cooperation in therapy.
    • The described alphabet and Morse code programs represent a valuable, accessible tool for improving quality of life.
