Usability evaluation from client-side traces using heatmap and system usability scale

In this project, we investigate the usability of a gamified application developed as part of the e-learning system for the University of Souk Ahras. The online application is integrated within the university web portal, allowing students and lecturers to ask questions and receive answers from other students or lecturers within the university about any modules. This would result in creating a knowledge base of questions and answers for every module that future students could benefit from without the need to ask their lecturers again. We propose the use of heat maps for assessing usability based on client-side traces where a JavaScript app is used to track user behaviors while exploring the university website remotely without accessing or modifying the main university website. The suggested tool is integrated into the webpage by inserting asingle line of JavaScript code. After logging and storing the data, a heat map is generated from this data using PHP and JavaScript to assess the most active areas where users pay attention when interacting with the website. Furthermore, we created an online implementation of the System Usability Scale questionnaire in order to assess the satisfaction of university participants in using the Question Board platform. The SUS is considered after using the platform. For users who couldn't manage to use the application, we have devised a special questionnaire. Finally, a questionnaire is devised for users who haven't used the application in order to figure out the main reasons for the weak turnout on the platform
