Gliederung

Text

Introduction: Obesity has reached epidemic proportions globally. WHO projects that by the year 2015, approximately 2.3 billion adults will be overweight and more than 700 million will be obese [1]. Our Physical Wellness Application is a second generation persuasive tool [2] which helps users in fighting obesity.

Methodology: What makes our concept different from others is the emphasis on usability. We started off with research on iPhone user profiles, demographics and health [3], moved on to contextual enquiry [4], requirement analysis, interaction models [4], use objects [5], information

architecture [6], visual design, iterative testing and redesign and ended up with high fidelity mock-ups on Axure http://www.axure.com/. Usability is involved throughout the design process like in initial testing of competitor designs, conducting contextual enquiries and testing of prototypes. We

took the user into account at every step which led to creation of user friendly, engaging and efficient user experiences [7].

Result: The study develops a successful symbiotic relationship between the medical and mobile domain. The result is a robust and user friendly mock-up of a wellness application for target users of age 18–40 years. The application employs tunnelling, tailoring and suggestion as strategy for

effective persuasion [2]. The application provides user with customized recommendations on workouts. The user is led through a step by step sequence of actions with relevant, customized interventions, providing the right kind of motivation and thereby providing a better user experience [2]. The usability evaluation tests make the application more intuitive. This increase the likelihood of usage and repeat usage and hence improves ROI [7].

Discussion: We discuss how concepts of usability are employed in development of an intuitive and user friendly application. We talk about how our application uses motivation and persuasion to help user in fighting obesity. We look at strategies employed for effective persuasion. Finally

we discuss the impact of usability on the final design of the application.
