THE ASSESSMENT OF CALORIEMASTER THROUGH THE SYSTEM USABILITY SCALE

Abstract

The increasing prevalence of obesity worldwide and associated health issues suggest that there is an urgent need for successful digital health interventions. CalorieMaster is a digital solution that is designed to provide individuals with the ultimate tool to ensure they achieve a good health and fitness from their diet through advanced nutrition management. This proposed application provides users with simple tracking of their caloric intake, detailed macronutrient breakdowns, including those that are sugar-derived, as well as total sugars, and innovative graphics displaying easy-to-understand statistics on daily dietary habits. Features include a large food database, easy and simple tracking of foods, personalised meal plans based on weight loss goals and eating preferences, and dynamic progress monitoring with interactive charts. CalorieMaster’s user interface and user experience are assessed in this paper, considering navigation, functionality and aesthetic design through a user-centred perspective. The outcomes of the evaluation include, for instance, high user satisfaction with respect to ease of use and intuitive interaction design on the one hand, as well as positive statements towards personalised meal recommendations and progress tracking. In addition, limitations were observed in the search feature and food database.
