Area of Science:

  • Human-Computer Interaction
  • Assistive Technology Design
  • Disability Studies

Background:

  • Designing usable and accessible cell phones for persons with disabilities is crucial.
  • Existing methods for requirements elicitation may not adequately address the needs of diverse user groups.
  • Assistive technology development requires a user-centered approach.

Purpose of the Study:

  • To develop and evaluate the Needs Analysis and Requirements Acquisition (NARA) framework.
  • To elicit and construct user requirements for cell phones as assistive technology.
  • To ensure cell phones are both usable and accessible for individuals with disabilities.

Main Methods:

  • Utilized semi-structured interviews and a focus group to gather user information.

Related Experiment Videos

  • Employed a systematic approach for translating elicited information into actionable requirements.
  • Focused on the elicitation and construction stages within the NARA framework.

    • Main Results:

    • Identified specific user requirements for general and feature-specific phone attributes.
    • Several identified requirements aligned with universal design principles, enhancing accessibility.
    • Validated the framework's ability to capture diverse user needs.

    Conclusions:

    • The Needs Analysis and Requirements Acquisition (NARA) framework is a practical and efficient tool.
    • NARA facilitates the development of user requirements throughout the product development cycle.
    • The framework supports the creation of more usable and accessible assistive technologies.
