This translate into the amount of time taken to learn, recall and complete the procedure for certain task with respect to a given system or device. It was in the light of this that this work took a look at the existing human computer interaction (HCI) usability testing techniques with the intention of empirically establishing which among cognitive walkthrough, heuristic evaluation and user group is the most efficient in identifying and correcting system’s usability problems. To create the research pathway a detail review of related work was undertaken to identify the lacuna therein for the research direction. A case study of the Nigerian Defence Academy (NDA) website was used as a specimen for administering the usability test methods and the outcome of each was documented. The research methodology adopted a purposive and stratified sampling technique to reduced biased and increased reliability of the representative sample chosen for this research. The sample chosen was an extract of final year undergraduate students of Federal College of Education (FCE) Pankshin, an affiliate of University of Jos, Plateau State, Nigeria. The students have taken a course in Human Factor in System Design, which provided them with adequate training in usability test techniques, 20 out of the total 30 students with the requisite skill were chosen to undertake the test process. The data collated passed through paired sample T-test procedure of the compare-mean analysis with confidence interval percentage of 95%, using the IBM Statistical Package for the Social Sciences (SPSS) version 26. The outcome of the T-test showed that the respective means of cognitive-walkthrough, heuristic-evaluation and user-group are 5.750, 4.900 and 6.350, with respective correlation coefficients of 0.192, 0.54 and 0.624. This shows a strong relationship between each pair of the test techniques. However, user-group usability test technique with the highest mean accuracy interval of 1.450 is the best in terms of performance relative to the other two techniques. Finally, the result of the analysis as well as charts created and the participant’s findings were summarized thus proffering way forward and recommendations for the improvement of system and user interaction.

INTRODUCTION Human Computer Interaction (HCI) deals with two-way communication between a user and a system. This usually involved a communication pathway that mediates between Nengak Iliya Sitlong, Department of Computer Science, Federal College of Education, Jos, Nigeria Abraham E.

Irhebhude, Department of Computer Science, Nigerian Defence Academy, Kaduna, Nigeria the system and the user such as the graphic user interface that is linked to the background logic that facilitates communication process [37]. Fields of concern that led to the successes in HCI comprise of computer science, cognitive science, human factors, software engineering, management science, psychology, sociology, and anthropology as shown in Figure 1.1 [25]. Initial explorations in the field of HCI centered on concepts and interest surrounding user interface. Quintessential areas of interest in HCI relates to the attributes of input and output channels on interactive gadgets, this revolves around qualities such as interface learnability for new users as well as efficiency and knowledge replicability for regular users. HCI also focus on the provision of right and instinctive array of interaction features such as command languages, menus, and graphical user interfaces (GUI). The paradigm shift in HCI is focusing towards patterns and the intended role by the user. The value of a system is the measure of collection of functions or benefits it render to the users. However, this value becomes obvious when the benefits or functions enhance the effectiveness and efficiency of users operations [2]. Figure 1.1: Composition of HCI Field [25]. Usability of a system that provide some services is the extend or rate at which the system can be applied proficiently and satisfactorily to achieve specific goals for a given user. The true satisfactoriness of a system is attained when there is remarkable equilibrium between the system’s services and user friendliness of the system [17]. It is in line with this, that this research focused on the available usability evaluation techniques, which are user-group, cognitive walkthrough and A Comparative Analysis of Website Usability Evaluation Techniques Nengak Iliya Sitlong, Abraham E.
