Qualitative Interface evaluation - Assignment Example In this regard, some authors have provided guidelines and methods for developing and evaluating graphical user interfaces (GUI) and web designs. Some of the guidelines and methods for evaluating a website are given below: i. Heuristic Evaluation ii. Cognitive Walk-through iii. Pluralistic Walkthrough iv. Summative Evaluation v. Formative Evaluation Apple Web Design Guideline vi. IBM Web Design Guidelines vii. Library of Congress World Wide Web Style viii. Yale Web Style Guide Selection and Justification of Two Methods In this paper, I have evaluated a website having URL: http://www.thorpepark.com/, using two of the above usability methods for evaluating a website. The first method that I have chosen for evaluation of the website is Heuristic Evaluation, developed by Jakob Nielson, it is the most increasingly used method for evaluation and improvement of user interface designs. As per a study on comparison of four techniques of evaluation, the largest number of problems in a website ( more than 50 %) were found by the method of heuristic evaluation, this include most severe as well as least severe. Four to Five (4-5) user interface evaluators (experts) are required, in order to evaluate a website by this method, but as far as this assignment is individual, therefore, the website has only been evaluated by me. The second method that I have chosen in this paper in order to evaluate the said website is Cognitive Walkthrough, a method for identifying and fixing errors that transpire when browsing and searching for information on a website. This method helps defining and evaluating goals, assumptions and tasks in users’ perspective. The cognitive walkthrough focuses on the user’s tasks, user interface design, user’s experience and how fast the user can learn the functions/tasks. Furthermore, this method uses fewer resources in terms of human, equipment and time. I chose both of above methods, for not only the advantages given above but also they a re poles apart from each other and we are expecting to have diverse results. Furthermore, these methods are used to evaluate the accessibility, usability and adaptability of the website, interface evaluation, with both perspectives user’s as well as website and its behavior. The browser that I have used in this paper is the Internet explorer version 9. Furthermore, I have given below the URL of the pages that I have included in this paper for evaluation. Heuristic Evaluation Technique In order to evaluate the website through the heuristic evaluation technique, I have used set of criteria mentioned by Jakob Nielsen heuristic. Sundry aspects of the website were reviewed, violations identified, and severity ratings assigned to the evaluated issues. It is based on a permutation of occurrence, impact, and determination of usability problem. The ratings of the Nielson follow a 0 to 4 scale and map to the following information. 0 = I don’t agree that this is a usability probl em at all 1 = Cosmetic problem only: need not be fixed unless extra time is available on project 2 = Minor usability problem: fixing this should be given low priority 3 = Major usability problem: important to fix, so should be given high priority 4 = Usability catastrophe: imperative to fix this before product can be released Following are the ten (10) set
