In recent years, there has been a renewed interest in using wearable technology as a way of promoting healthy behaviors. The most popular manifestation of such a trend is the health band - bands, such as the Nike Fueldband and the Jawbone UP, that passively track data such as the number of steps taken by its wearer that day. The software can then take this data and present it in a useful way to the user, or give meaningful recommendations on how to improve one’s exercising behavior. The purpose of this study is to measure whether strategic alterations of the content and how it is displayed to the user can lead to healthier behavioral outcomes. In prior studies, using different persuasive strategies, such as Cialdini's Persuasive Principles, has been shown to be effective. Novel to our approach is a field study adaptation that focuses on the persuasive strategy of authority.
