This review explores eye-tracking technology for communication in severely disabled patients. It details a system using gaze interpretation and speech synthesis to enable eye-controlled communication.

Area of Science:

  • Biomedical Engineering
  • Assistive Technology
  • Human-Computer Interaction

Context:

  • Severely disabled patients often lose the ability to communicate verbally.
  • Eye movements can serve as a primary communication channel with advanced technology.
  • Existing assistive communication systems require further integration and refinement.

Purpose:

  • To review the state-of-the-art in gaze interpretation, text construction interfaces, and speech synthesis for eye-controlled communication systems.
  • To introduce the Visual Speech Synthesis (Síntesis Visual del Habla [SiVHa]) system developed at the Public University of Navarra.
  • To highlight the potential of integrated eye-tracking systems for enhancing patient communication.

Summary:

  • This review examines the three core modules of an eye-controlled communication system: gaze interpretation, user interface for text construction, and speech synthesis.

  • It assesses current technologies in each module, identifying advancements and limitations.
  • The Visual Speech Synthesis (SiVHa) system is presented as a novel solution integrating these components.

    • Impact:

    • Enables severely disabled individuals to communicate effectively using only eye movements.
    • Advances the field of assistive technology by integrating gaze interpretation, text construction, and speech synthesis.
    • Offers a pathway to greater independence and improved quality of life for patients with communication impairments.
