Title: Janne Käki: Wearable Data and Experimental Programs
Introduction
Janne Käki is an inventor based in Helsinki, Finland, and works at Oura Health Oy. His patent work describes ways to use data from wearable devices to support personalized experimental programs and track behavioral changes.
Latest Patents
Käki is associated with 1 patent: “Techniques for Experimental Programs Using Data from Wearable Device.” The patent describes acquiring a user’s baseline photoplethysmography (PPG) data through a wearable device, then presenting experimental programs based on that data. Each program is linked to one or more behavioral changes. After the user selects a program, the system collects additional PPG data during the program and uses that data, along with information provided through a user device, to assess adherence. The user device can then display changes between the baseline and subsequent measurements.
Career Highlights
At Oura Health Oy, Käki’s patent work focuses on combining wearable-device measurements with user-facing software. The described approach connects physiological data to behavioral experiments and presents users with information about changes over time.
Collaborations
Käki’s listed coworkers include Laura Furman and Quynh Nguyen.
Conclusion
Janne Käki’s patent describes a wearable-data system that helps users explore behavioral changes and review related physiological measurements.
