EVALUATION OF COVID-19 CONTACT TRACING APPLICATION OF INDIA – “AAROGYA SETU” USING SYSTEM USABILITY SCALE.

Abstract

Health is multi-dimensional, determined by physical, mental, environmental, social, political, cultural factors, etc., inuenced by various emerging and ongoing viral infections and diseases. COVID-19 is the name of existing novel viral pneumonia which is coined by WHO in 2020 whereas the International Committee on Taxonomy of Viruses suggested this as “Severe Acute Respiratory Coronavirus-2” based on phylogenetic and taxonomic analysis of pandemic novel coronavirus. Due to its fatal clinical symptoms, WHO has declared it a pandemic outbreak. To combat this, “AAROGYA SETU”, a contact tracing app, developed and approved by the Indian government and National Informatics Centre, warns the users if they have crossed paths with any infected person recently. The critical review of this application helps to evaluate its potency in terms of its usability, learnability, and acceptability amongst the users using a system usability scoring system (SUS). This paper shows how such applications can be tested using SUS based out of technical glitches, client's understanding and acceptability to their social expectations, in proactively reaching out to and informing the users of the app regarding risks, best practices, and relevant advisories pertaining to the containment of COVID-19.
