You Have Evaluated An E Commerce Websiteamazoncom During the Websit

You have evaluated an e-commerce Website (Amazon.com) during the Website Review Assignment, which likely has several usability flaws. For this assignment, you are to recreate a single wireframe based on the Website you’ve reviewed with your team (Amazon.com). In this wireframe, you are to include the following critical elements: appropriate color scheme (for those requiring accessibility needs), consistent font/size ratio, an example of text layout, an example of image layout, and an example of use of form elements (such as buttons and fields). In addition to creating the wireframe, you are to prepare a brief summary that explains the changes you’ve made from the Website Review Assignment to the current wireframe. Please be as specific as possible in applying the terminology you’ve learned throughout the course.

Paper For Above instruction

Creating an effective wireframe for an e-commerce website such as Amazon.com requires a meticulous approach that emphasizes usability, accessibility, and visual hierarchy. The original Amazon website, while highly functional, demonstrates areas where improvements can enhance user experience, especially for users with accessibility needs. Based on the evaluation, the wireframe I developed incorporates several critical design elements including an appropriate color scheme, consistent font and size ratios, clear text and image layouts, and intuitive use of form elements.

Color Scheme and Accessibility

A primary consideration in designing the wireframe was selecting an accessible color scheme. Amazon’s original website utilizes a predominantly white background with orange accents, which may not provide sufficient contrast for users with visual impairments. In the wireframe, I adopted a high-contrast color palette featuring dark gray text on a white background for readability, with orange used sparingly to highlight important call-to-action buttons, such as "Add to Cart" or "Buy Now." This approach aligns with Web Content Accessibility Guidelines (WCAG) 2.1, which recommend a contrast ratio of at least 4.5:1 for normal text (W3C, 2018). Additionally, I incorporated accessible color selections that are friendly for users with color vision deficiencies, ensuring that navigational elements are distinguishable without relying solely on color cues.

Font and Size Consistency

Consistency in font and sizing is vital for maintaining clarity and guiding user focus. The wireframe employs a primary font family, such as Arial or Helvetica, with a clear hierarchy: headers are set at 24px, subheaders at 20px, and body text at 14px. This ratio maintains readability across devices and screens. I also ensured consistent line spacing and spacing between elements to improve visual flow and reduce cognitive load (Lidwell, Holden, & Butler, 2010). The use of bold text for headings and slightly larger fonts for product titles further assists users in quickly scanning and locating relevant information.

Text Layout and Image Placement

Effective text layout enhances comprehension and user engagement. The wireframe organizes product descriptions, user reviews, and specifications in a structured format with clear headings and bullet points where applicable. The product image is positioned prominently on the right side of the description, making use of sufficient white space to prevent clutter. Images are scaled correctly to preserve quality without overwhelming the layout. Consistent alignment and grid-based placement ensure a balanced and professional appearance, supporting the user’s navigational flow.

Form Elements and User Interaction

In the redesigned wireframe, form elements are designed to facilitate seamless interaction. The search bar in the header is equipped with a visible input field and a clearly labeled button with an accessible label. Product options, such as quantity selection, are presented via a dropdown menu or stepper widget, designed for easy use both on desktop and mobile devices. Action buttons like "Add to Cart" and "Buy Now" are distinctly styled with contrasting colors and ample clickable areas to accommodate users with motor impairments or on smaller screens (Nielsen & Molich, 1990). Form validation messages are positioned near the fields to provide immediate feedback, enhancing usability.

Summary of Changes from the Website Review

Compared to the original Amazon website reviewed, the wireframe introduces a more accessible color scheme, emphasizing high contrast and color combinations that support users with visual impairments. Font sizes and styles are standardized to ensure consistency, improving readability across different sections. The layout offers a clearer visual hierarchy, with product images and descriptions presented in a balanced, uncluttered manner, facilitating quicker information processing. Additionally, form elements are optimized for ease of use, with larger touch targets and clearer labels, making interactions more intuitive, especially for users with disabilities. These modifications collectively aim to enhance the overall usability, accessibility, and aesthetic appeal of the e-commerce interface.
