With the physical and behavioral limitations of the user group, the app was designed with a muted color palette to lessen sensitivity to over-stimulation, buttons were created instead of swiping to account for users with pharma-induced tremors, and simple illustrations conveyed complex, abstract concepts. Through progressive disclosure, the experience guides the user along a visual path to track progress, participate in multifaceted exercises throughout the duration of the journey, and plan for future success in becoming cigarette free. Each point in the journey provides them with positive reinforcement and lessons in which they’re able to understand their urges, rather than the standard approach of jumping straight into quitting, providing increased motivation to continue. As the user moves through the actual quitting process they track their mood, how physical aids are contributing, cost savings tallies, and are provided immediate access to a pre-designated quit coach via the application.
What began as 200 hours of patient testing with simple paper prototypes has progressed into a high-fidelity application that initially underwent rigorous National Institute of Health funded user testing through the University of Washington and Harborview Medical Center. Now at Duke University, Dr. Vilardaga is conducting a second phase of randomized clinical trials.
