Area of Science:

  • Assistive Technology
  • Human-Computer Interaction
  • Disability Studies

Background:

  • Computers offer significant opportunities for individuals with disabilities.
  • Standard computer setups present accessibility challenges for many users.
  • Existing resources for adaptive computer hardware and software are fragmented.

Purpose of the Study:

  • To review major databases for adaptive computer technology.
  • To identify limitations in current information resources for selecting assistive devices.
  • To propose an improved methodology for choosing computer accommodations.

Main Methods:

  • Reviewed six major databases cataloging adaptive computer hardware and software.
  • Analyzed database content for detail on device compatibility with user skills and tasks.

Related Experiment Videos

  • Assessed factors influencing database selection, including access, frequency of use, and cost.

    • Main Results:

    • No single reviewed database provides comprehensive information for matching devices to user needs and abilities.
    • Current methods for selecting assistive computer aids are often unsystematic.
    • Database suitability varies based on user needs, access methods, usage patterns, and cost.

    Conclusions:

    • A more integrated approach is needed for selecting adaptive computer aids.
    • This approach should combine capability assessment, task-based needs analysis, detailed device databases, and usability testing.
    • Implementing this integrated strategy can improve the selection of appropriate computer accommodations for users with disabilities.
