Abstract: Methods and systems for improving a presentation function of a client device based on feedback data indicative of presentation effectiveness are disclosed. A server transmits, over a communication network, a first instruction that configures the client device to provide a first presentation via a user interface to an individual. The server receives physiological data collected by one or more sensors of the client device and associated with the individual and the first presentation. Based on feedback data, including the received physiological data, representative of behavior change subject to the first presentation, the server computes an effectiveness assessment of the first presentation.

Abstract: Some embodiments of the present disclosure provide a method that includes compiling, for each of a plurality of individuals, health-related data in a plurality of categories, determining that a given individual has a particular type of health-related data in a particular set of one or more categories, and based on the determination that the given individual has the particular type of health-related data in the particular set of one or more categories, transmitting from a server device to a client device associated with the given individual, over a communication network, a first instruction configured to cause the client device to present a first incentive designed to cause a change in the given individual's health-related data. The first incentive may make use of a first type of motivational foundation. The method may also include determining whether the first incentive was effective or ineffective.
