Evaluation of System Usability Scale as A Marker of Non-Human Computer Interface’s Usability: A Sanitizer Container-Based Study

The use and the production of sanitizers have increased in the post-pandemic situation to prevent the further spread of COVID-19. Usability assessment of sanitizer containers is essentially required to evaluate the effectiveness, efficiency, and satisfactory use of the sanitizer containers. This study aimed to evaluate the system usability scale (SUS) as a marker of perceived usability of non-human computer interfaces, such as - sanitizer containers. The perceived usability of three types of sanitizer containers was evaluated using SUS. The authors have measured the reliability, convergent, and discriminant validity to evaluate SUS as a marker of usability of sanitizer containers. The result showed that SUS lacks convergent validity though it has a higher reliability coefficient. Thus, this is not the best measure of usability for non-human computer interfaces like-sanitizer containers. The SUS was applied on the flip cap, finger-pressure pump, and spray-type sanitizer containers. The finger-pressure pump container has exhibited a higher SUS score than others. The results of this study have given an idea about the usability of three different kinds of sanitizer containers. This research provides an overview of the application of SUS on non-Human computer interfaces like sanitizer containers. This study provides limitations like lack of convergent validity and ideas to overcome common method bias.
