Computer access for persons who are blind or visually impaired: human factors issues

Area of Science:

• Human-Computer Interaction
• Assistive Technology
• Usability Engineering

Background:

• Computers offer significant potential for integrating visually impaired individuals into mainstream society.
• Current integration is limited by human factors challenges, particularly with interface design.

Purpose of the Study:

• To discuss human factors issues hindering computer accessibility for the visually impaired.
• To review problems associated with icon-based interfaces for users with vision impairments.
• To argue that these human factors issues are fundamental to all users.

Main Methods:

• Discussion of human factors principles relevant to computer accessibility.
• Review and analysis of icon-based interface design challenges.
• Conceptual argument regarding the universality of identified human factors issues.

Main Results:

• Human factors issues are the primary barrier to computer integration for the visually impaired.
• Icon-based interfaces present specific usability challenges for visually impaired users.
• Identified human factors issues are not exclusive to visually impaired users but are fundamental to all users.

Conclusions:

• Addressing human factors in computer design is crucial for the inclusion of visually impaired individuals.
• Improvements in interface design for visually impaired users can enhance usability for all.
• Research into human factors for vision-impaired users holds potential benefits for sighted users as well.
