Trend prediction device and trend prediction system

摘要

A trend prediction device that is versatile and capable of improving the accuracy of predicting a trend in a user's physical condition is provided. The trend prediction device includes: a sensor-data converter configured to convert sensor data detected by a sleep sensor into a sleep-related parameter for making a physical-data-trend judgment; a parameter acquisition unit configured to acquire a lifestyle-related parameter that indicates an action of the user during a non-sleeping period, and possibly changing the physical-data trend; and a parameter comparator configured to compare the sleep-related and the lifestyle-related parameters with respective reference parameters. The trend prediction device is configured to judge whether the physical data has an increase or a decrease in trend on the basis of the comparison result of the sleep-related and the lifestyle-related parameters with their respective reference parameters.
