Publication number: 20240122544Abstract: Methods, systems, and devices for experimental programs are described. A method includes acquiring baseline PPG data from a user via a wearable device throughout a time interval, and displaying one or more experimental programs via a user device based on the baseline PPG data, where each experimental program is associated with one or more behavioral changes. Upon a selection of an experimental program, the method includes acquiring additional PPG data from the user via the wearable device throughout a time interval of the experimental program. The method includes identifying adherence of the user to a behavioral change of the experimental program based on the additional PPG data and/or information received via the user device. The method further includes displaying, via the user device, changes between the baseline PPG data and the additional PPG data based on identifying the adherence to the behavioral change.Type: ApplicationFiled: October 18, 2023Publication date: April 18, 2024Inventors: Laura Furman, Quynh Nguyen, Sally Chan, Janne Käki, Dmitrii Aleksandrov, Damian Winiarczuk, Marcin Banaszynski, Mika Erkkilä, Geoffrey Koops, Jake Harris Sherman, Ivan Uladzimiravich Markevich, Lauren Maymar
