Evaluation and Redesign of a Web Interface using Usability Heuristic Principles

Abstract: The main aim of this thesis project is to select and redesign a website which was originally designed without using the HCI design principles. The website “Atari best electronics” (https://www.best-electronics-ca.com/) was chosen and evaluated using usability heuristics. After finding the flaws in the website, it is redesigned using the HCI design principles using Google sites. The redesigned website is then surveyed using the System Usability Scale (SUS). The results of the survey are presented in the report. Background: The UI/UX of any website increases drastically if the website is designed with the HCI principles in mind. Most of the websites do not follow the design principles. This affects the reach and usage of the website. The users using these websites are very quick to quit. The websites can be designed/redesigned using the HCI designed principles and increase the user experience.  Objectives: The objective of this project is to evaluate the chosen website and redesign it by using HCI design principles and conduct survey to understand the user’s perspective on the redesigned website. Methods: This project uses two methods in order to get results and solution of the proposed research questions. The heuristic evaluation method helps us find the flaws in the website and lets us redesign the website using HCI design principles. The survey evaluation method helps us understand the user’s perspective on the redesigned website. Results: The website is redesigned using the HCI design principles and a survey questionnaire is shared, and the responses are collected, and the results are represented in the form of bar graphs. Based on the results of the survey, we find out whether or not the users liked using the redesigned website. Conclusion: Using HCI principles in designing/redesigning a website increases the usability of the website. After analyzing the survey, we understand that the user experience is greatly affected when a website is designed using HCI design principles.
