Website Review: Human-Computer Interaction And Usability

Website Review Human Comput Inter Usabilityyour Task In This Assig

Website Review – Human comput Inter & usability Your task in this assignment is to perform a usability evaluation of an existing e-commerce Website. The assignment should be between 8 – 10 pages each. Including images is highly encouraged to demonstrate the usability issues within the site. Use the following points as guidelines when writing the Website Review:

  • System Identification: What Website are you evaluating? What is its main purpose, and what are the target users?
  • Tasks and Activities: As an evaluation participant, what are you trying to complete with the system? Be sure to identify at least three use cases. Upon identification, complete each identification path you are trying to identify, including the strengths and weaknesses of each task and activity.
  • Metrics: As much as possible, use measurable criteria as you’ve read in the Preece text. Identify those methods you’ve applied in your review of the Website.
  • Application: Using the Nielsen 10 heuristics for usability design, explain how each task can be improved.
  • Assessment: Recommend five changes the Website platform can make to improve its usability posture.

Paper For Above instruction

The digital landscape has transformed the way consumers interact with online platforms, especially e-commerce websites, which have become essential for modern trade. A thorough usability evaluation of such a website involves systematic analysis of interface design, task workflows, user satisfaction, and identifying opportunities for improvement. This paper focuses on evaluating [specific website name], analyzing its usability features, and proposing actionable recommendations based on Nielsen's usability heuristics to enhance user experience.

System Identification

The chosen website for this evaluation is [website URL], primarily dedicated to [main purpose, e.g., selling electronics, fashion apparel, etc.]. Its target users include [target demographics such as age groups, tech-savvy individuals, casual shoppers, etc.]. The website aims to provide a seamless shopping experience by offering a broad product catalog, secure payment options, and personalized recommendations. Understanding the core goals and user profiles is critical for framing usability assessments and addressing specific user needs.

Tasks and Activities

In evaluating the usability, three primary use cases have been identified:

  1. Product Search and Selection: Users aim to find specific products using search filters and navigational menus. Strengths include detailed filters and product categorization, while weaknesses involve inconsistent search results and limited filtering options on mobile devices.
  2. Adding Items to Cart and Checkout: Users select products, add them to their carts, and proceed to purchase. The process is generally straightforward but is hindered by unclear pricing on some items and a confusing multi-step checkout process.
  3. Account Management and Order Tracking: Users log into their accounts to review orders or modify personal information. Strengths include easy login options; weaknesses involve insufficient clarity on order statuses and limited account customization features.

Each of these tasks requires smooth navigation and minimal errors to ensure high user satisfaction. The strengths and weaknesses identified provide insights into specific areas needing usability improvements.

Metrics

Utilizing Nielsen’s heuristics, several measurable usability criteria are applicable:

- Error Rate: Number of user errors during navigation, such as incorrect selections or failed searches.

- Task Completion Time: Time taken to complete key tasks like purchase or account updates.

- User Satisfaction: Measured through post-task surveys or feedback forms.

- Success Rate: Percentage of users successfully completing tasks without assistance.

- Consistency: Evaluation of visual and functional consistency across pages and devices.

These metrics were gathered through heuristic evaluation, user testing, and analyzing user feedback, enabling an objective assessment of usability strengths and gaps.

Application of Nielsen’s 10 Heuristics

Applying Nielsen's heuristics reveals specific improvements for each task:

1. Visibility of system status: Implement progress indicators during checkout to inform users of ongoing processes, reducing frustration.

2. Match between system and the real world: Use familiar language and icons consistent with common shopping paradigms to improve comprehension.

3. User control and freedom: Incorporate easy options to undo or modify actions, such as removal of items from cart.

4. Consistency and standards: Standardize button placements and navigation menus across pages.

5. Error prevention: Highlight required fields and validate inputs in real-time during forms to prevent errors.

6. Recognition rather than recall: Show previously viewed products or saved items to facilitate easier decision-making.

7. Flexibility and efficiency of use: Enable shortcuts for returning users, such as saved payment methods.

8. Aesthetic and minimalist design: Remove clutter and organize content logically to focus attention on essential elements.

9. Help users recognize, diagnose, and recover from errors: Provide clear error messages with instructions for correction.

10. Help and documentation: Offer accessible help sections and FAQs within the site.

Applying these heuristics systematically will significantly improve the shopping experience, reducing confusion and increasing satisfaction.

Recommendations for Usability Improvements

Based on the evaluation, the following five changes are recommended:

  1. Enhance Mobile Responsiveness: Optimize interface elements and filters for mobile devices to improve navigation and filtering efficiency.
  2. Streamline Checkout Process: Reduce steps in the checkout flow, incorporate guest checkout options, and clarify pricing at every stage.
  3. Improve Search Functionality: Implement advanced filtering, auto-suggestions, and better search algorithms to deliver relevant results quickly.
  4. Personalize User Experience: Use AI-driven recommendations, saved preferences, and customized content to foster engagement and loyalty.
  5. Strengthen Help and Support: Introduce chatbots, detailed FAQ sections, and easy access to customer support to assist users promptly.

In conclusion, a comprehensive usability review rooted in Nielsen’s heuristics provides critical insights into improving the user experience on e-commerce platforms. Addressing identified issues with targeted solutions can substantially increase user satisfaction, conversion rates, and overall platform success.
