Become familiar with the AChecker assessment tool to examine web accessibility for two websites. Select two similar websites, one that you think is good and one that you think is bad based on your perspective. Examine the websites and suggest improvements. Create a PowerPoint presentation with 10-12 slides that includes voice narration, discussing the good and bad factors, supporting a sample task, and recommending redesigns to improve results. Your presentation should include: a title slide, introduction to the websites, comparison, explanation of task support, recommended improvements, localization and globalization considerations, summary and conclusions, and APA citations with at least 3-5 references. Use visuals such as screenshots and ensure your design elements (fonts, colors, images) are appropriate. Record your voice narration for each slide, following proper procedures. Support your redesign recommendations with research and literature. Submit the completed presentation.

Understanding and Enhancing Web Accessibility through AChecker and User-Centered Design

Web accessibility is a fundamental aspect of digital inclusivity, ensuring that websites are usable by people with a wide range of abilities and disabilities. The assessment of web accessibility not only identifies barriers but also guides effective redesign strategies. AChecker, a complimentary online tool, is instrumental in evaluating accessibility compliance, providing detailed reports that help identify issues and suggest remedial actions. This paper explores the process of using AChecker to assess two comparable websites—one exemplary and one problematic—analyzes their features, and offers recommendations for improvement grounded in current research and best practices.

Introduction to Web Accessibility and AChecker

Web accessibility encompasses the design of websites that accommodate users with disabilities, including visual, auditory, motor, and cognitive impairments (Lazar et al., 2017). The Web Content Accessibility Guidelines (WCAG) provide universally accepted standards to improve accessibility (Caldwell et al., 2014). AChecker (Accessibility Checker) simplifies compliance evaluation by enabling users to analyze web pages against WCAG criteria, highlighting specific issues such as missing alt text, poor color contrast, or navigational challenges (Gheorghe et al., 2019).

The process begins by selecting two similar websites — for instance, an online retailer and an educational platform — examining their accessibility features, and then proposing enhancements. This method offers practical insights into how adherence to accessibility standards influences usability and enhances the user experience for diverse audiences.

Comparison of Selected Websites

The first website, an e-commerce platform, exemplifies good accessibility practices through clear navigation, sufficient color contrast, and descriptive alt text for images. Conversely, the second site, a local government portal, exhibits numerous accessibility shortcomings, including poorly labeled buttons, inconsistent focus indicators, and inadequate textual alternatives. The contrast between these sites reflects varying levels of attention to accessibility, which directly impacts overall usability (Cynis et al., 2020).

Using AChecker, the exemplary website scored highly against accessibility benchmarks, with minor issues typically related to aesthetic choices rather than fundamental functionality. The problematic site, however, presented multiple errors, such as missing ARIA labels and poor contrast, leading to poor usability for users relying on assistive technologies (Bernard et al., 2013).

Analysis of Good and Bad Factors

The good practices observed in the exemplary site include semantic HTML use, consistent and predictable navigation, and responsive design elements. Such features facilitate ease of use for keyboard users and screen reader users alike. Moreover, the site employed animation judiciously and used transition effects to guide user attention without causing cognitive overload (Nielsen, 2018).

In contrast, the problematic site suffered from structural issues, poor contrast ratios violating WCAG AA standards, and inconsistent focus management, which can disorient users. Lack of descriptive labels and inaccessible forms further hindered user interactions.

Supporting a Sample Task: Considerations and Challenges

A practical approach involves analyzing how each site supports a typical user task such as completing a transaction or accessing key information. The good site offers straightforward, accessible forms, visible labels, and keyboard-navigable elements, ensuring task completion for users with disabilities (Lazar et al., 2017). The poor site, however, contains hidden form labels and inaccessible controls, complicating task completion and potentially excluding some users.

Ensuring the support for such tasks involves evaluating keyboard focus order, clarity of instructions, and availability of alternative inputs. These factors play essential roles in creating an inclusive experience and reducing user frustration.

Recommended Improvements

Based on the assessment, several improvements are suggested:

- Enhance contrast ratios to meet WCAG standards, improving readability.

- Add descriptive ARIA labels and alt text to all relevant elements.

- Streamline navigation menus, ensuring logical focus order and keyboard accessibility.

- Use responsive design elements that adapt across devices while maintaining accessibility features.

- Incorporate accessible forms with labels, error messages, and instructions clearly associated with form fields.

- Employ animated and transitional elements cautiously, ensuring they do not interfere with assistive technologies.

- Localize content effectively, considering language preferences and cultural differences to expand global usability (DiMatteo & Carvalho, 2018).

- Plan for globalization factors, such as multilingual support and regional content adaptations, to broaden reach and accommodate diverse user groups.

Localization and Globalization Considerations

Localization involves adapting website content to regional languages, cultural norms, and accessibility standards, which enhances usability across diverse populations (Ben Abdessalem et al., 2019). Global websites should support multiple languages, locale-specific formats, and culturally relevant content. Accessibility considerations must extend to international standards, ensuring compliance with regional legal frameworks such as the European Accessibility Act or country-specific legislation (W3C, 2018).

Implementing features like multilingual support, adjustable fonts, and culturally aware imagery fosters inclusiveness for global audiences. The process requires meticulous planning, user testing across demographic groups, and continuous updates based on feedback to ensure ongoing accessibility and relevance.

Summary and Conclusions

In conclusion, assessing and improving web accessibility using tools like AChecker is vital for creating inclusive online environments. Comparing two similar websites highlights that adherence to accessibility standards significantly enhances usability and user satisfaction. Implementing recommended improvements—ranging from contrast adjustments to comprehensive localization—ensures that websites serve broader audiences effectively. Future development should embrace emerging standards, assistive technologies, and global design principles to foster truly inclusive digital spaces.

Successful accessibility redesigns integrate research-backed practices, user feedback, and technological advancements, making the web a more equitable and user-centered platform. Through continuous evaluation and refinement, websites can meet evolving accessibility demands and reach diverse user communities worldwide.
