A new assistive technology (AT) device was developed to aid a non-verbal child

Area of Science:

  • Assistive Technology
  • Speech-Language Pathology
  • Human-Computer Interaction

Background:

  • A young child with communication difficulties, unable to speak or read, required an alternative communication method.
  • Conventional communication devices were unsuitable due to the child's age and inability to speak or read.
  • An educator requested a wearable device to vocalize for the child, with visual cues.

Purpose of the Study:

  • To design and develop an effective assistive technology (AT) device for a non-verbal child.
  • To create a communication aid that provides visual cues synchronized with synthesized speech.
  • To overcome the limitations of initial prototypes and develop a practical, user-friendly device.

Main Methods:

  • Iterative design process involving educators and students.

Related Experiment Videos

  • Development of a new prototype incorporating a high-resolution graphic liquid crystal display (LCD).
  • Integration of a voice recording chip and microcontroller for enhanced functionality.
  • Modification of the device form factor from wristwatch to lanyard for improved usability.

    • Main Results:

    • The initial prototype, while functional, was impractical for daily use.
    • A redesigned device was successfully developed using advanced components like an LCD, voice chip, and microcontroller.
    • The final device, packaged for lanyard wear, offered improved visual cueing capabilities.
    • The design shift accommodated technological limitations while enhancing user experience.

    Conclusions:

    • The redesigned AT device offers a viable communication solution for non-verbal children unable to read.
    • The integration of visual cues with synthesized speech enhances communication effectiveness.
    • The project highlights the importance of iterative design and technological adaptation in developing effective AT solutions.
