Patent number: 11350829Abstract: An activity monitoring device, methods and computer readable media are provided. The activity monitoring device includes a housing configured for attachment to a body part of a user and a display screen attached to the housing. Further included is a first sensor disposed in the housing for capturing motion of the activity monitoring device when attached to the body part of the user and a second sensor disposed in the housing for sampling a heart rate of the user. Memory is disposed in the housing for storing the motion captured by the first sensor and the heart rate sampled by the second sensor. A processor is disposed in the housing and is configured to determine a physical state of the user during a period of time. For motion that is below a threshold the processor identifies the physical state to be a sedentary state and for motion that is at or above the threshold the processor identifies the physical state to be an active state.Type: GrantFiled: February 5, 2020Date of Patent: June 7, 2022Assignee: FITBIT, INC.Inventors: Shelten Gee Jao Yuen, James Park, Eric Nathan Friedman, Mark Manuel Martinez, Andrew Larsen Axley

Publication number: 20220079440Abstract: Systems and methods for determining a sedentary state of a user are described. Sensor data is collected and analyzed to calculate metabolic equivalent of task (MET) measures for a plurality of moments of interest. Based on the MET measures and a time period for which the MET measures exceed a threshold value, it is determined whether the user is in a sedentary state. If the user is in the sedentary state, the user is provided a notification to encourage the user to perform a non-sedentary activity.Type: ApplicationFiled: September 24, 2021Publication date: March 17, 2022Inventors: Jacob Antony Arnold, Allison Maya Russell, Zachariah Lord Wasson, II, Shelten Gee Jao Yuen
