This study introduces grammar-guided writing to help graphic sign users create grammatically correct text messages for email. A learning path and complementary input methods support users in developing language skills and composing messages effectively.

Area of Science:

  • Assistive Technology
  • Natural Language Processing
  • Human-Computer Interaction

Background:

  • Graphic sign users often face challenges in constructing grammatically correct text messages.
  • Existing methods may lack sufficient support for developing complex sentence structures.

Purpose of the Study:

  • To introduce a grammar-guided writing method for assisting graphic sign users in composing morphologically and syntactically correct text messages.
  • To enhance email composition for users with varying language proficiency levels.

Main Methods:

  • Developed a grammar-guided writing system utilizing high-frequency phrase and sentence structures from a parsed email database.
  • Integrated a progressive learning path for users to advance from simple to complex grammatical structures.

  • Augmented the system with two complementary input methods: pre-programmed messages/phrases and free graphic sign selection.

    • Main Results:

    • The system provides structured guidance for text message construction.
    • Users can progress through a learning path tailored to their developing language skills.
    • Flexible input options cater to different user needs and preferences during email composition.

    Conclusions:

    • Grammar-guided writing effectively supports graphic sign users in producing correct and coherent text messages.
    • The combination of guided structures, a learning path, and flexible input methods enhances the usability and effectiveness of digital communication for this user group.
