Evaluation of the Usability of a Mobile Application for Public Air Quality Information

This contribution summarizes the results achieved from a summative usability study considering the efficiency, effectiveness, and subjective satisfaction of final users when using Air Quality, a new mobile software for Public Air Quality information. Fifty-one participants tested the user interfaces of a prototype of the application. We use the IBM Computer System Usability Questionnaire (CSUQ) in order to assess the user experience (UX). The Microsoft Desirability Toolkit is also applied as complementary tool. We present experimental results based on subjective appreciations and self-reported feed-back. It suggests a favorable trend towards the usability of the application. Nevertheless, we have found that the quality of the information is a deficiency in the mobile application. We analyze some recommendations to improve the mobile application.
