Determining Sleep Stages and Sleep Events Using Sensor Data

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining sleep stages and sleep events using sensor data. In some implementations, sensor data is obtained over a time period while a person is sleeping. The time period is divided into a series of intervals. Heart rate and changes in the heart rate are analyzed over the intervals. Based on the analysis of the heart rate changes, sleep stage labels are assigned to different portions of the time period. An indication of the assigned sleep stage labels is provided.

1. A method performed by one or more computing devices, the method comprising:
obtaining, by the one or more computing devices, sensor data generated by one or more sensors over a time period while a person is sleeping; dividing, by the one or more computing devices, the time period into a series of intervals; analyzing, by the one or more computing devices, heart rate and the changes in the heart rate of the person indicated by the sensor data over the intervals; based on the analysis of heart rate the heart rate changes, assigning, by the one or more computing devices, sleep stage labels to different portions of the time period; and providing, by the one or more computing devices, an indication of the assigned sleep stage labels.
