Area of Science:

  • Electropalatography
  • Assistive Technology
  • Human-Computer Interaction

Background:

  • Traditional tongue switches have limitations in sensitivity and consistent positioning.
  • Severely physically disabled individuals require advanced control interfaces for daily tasks.
  • Oral cavity offers a unique environment for high-speed, agile tongue movement.

Observation:

  • An intra-oral device was developed based on electropalatography principles.
  • The device maintains a consistent tongue-to-sensor positional relationship.
  • The tongue operates within the natural confines of the oral cavity.

Findings:

  • The system significantly increases the range and sensitivity of control for users.
  • Customizable sensor arrays allow for tailored switch configurations (size, shape, position, number).

Related Experiment Videos

  • Practice enhances user accuracy with the intra-oral control system.

    • Implications:

    • This technology offers a versatile and adaptable solution for assistive communication and control.
    • Potential to improve independence and quality of life for individuals with severe physical disabilities.
    • Further development is needed to address practical challenges encountered during system use.
