Area of Science:

  • Computer Science
  • Assistive Technology
  • Human-Computer Interaction

Background:

  • Switch access is crucial for individuals with severe motor impairments to interact with computers.
  • Existing systems often lack comprehensive features or a unified development approach.
  • The need for adaptable and expandable communication solutions is significant.

Purpose of the Study:

  • To detail the development of two distinct systems: Switch Access to Windows (SAW) and Communicator Specification (Comspec).
  • To explore the methodologies employed in the creation of these assistive communication tools.
  • To identify and analyze the convergence in design and development approaches between SAW and Comspec.

Main Methods:

  • Descriptive analysis of the development process for SAW and Comspec.
  • Comparative examination of user and designer interfaces.
  • Evaluation of the convergence in development methodologies.

Main Results:

  • SAW was developed to facilitate communication between switch users and computer applications.
  • Comspec emerged as a comprehensive and expandable communication system.
  • A natural convergence was observed in the interfaces and development methodologies of both systems, despite differing initial objectives.

Conclusions:

  • The development of SAW and Comspec highlights a trend towards unified and adaptable assistive technologies.
  • Comspec is positioned to subsume SAW, offering a more integrated and comprehensive solution for switch users.
  • The convergence in development suggests a promising direction for future assistive technology design.
