Persuasive AI Voice-Assisted Technologies to Motivate and Encourage Physical Activity

Lack of physical activity (PA) is one major contributor to the high prevalence of modern-day chronic diseases. In this study, we design and implement an interactive PA motivation program for older adults (65+) and people with chronic conditions by adapting a commercially available artificial intelligence voice-assisted (AIVA) application and activity tracker (Alexa/Echo Show/Fitbit). Customized features are founded on persuasive technology theory and techniques- and evidence-based PA programs. A pilot study with four older adults for 5 days demonstrated moderate to good usability, learnability, satisfaction, and performance and key-persuasive techniques that enhance user experience and goal achievement. The study provides a tested model for PA behavior change using AIVA for feedback, education, and motivational guidance.
