Abstract

A nutrient intake amount estimation system according to an embodiment includes: a sensor that is disposed in a toilet space, and configured to detect an excretion smell related to excretion of a user of the toilet space; an estimation unit configured to estimate an estimated nutrient intake amount that is an amount of nutrients taken by the user by using an output of an estimation model that outputs information indicating an amount of nutrients estimated to be taken by the user in accordance with an input based on an output value of the sensor; and an output unit configured to output information based on the estimated nutrient intake amount.

First claim

What is claimed is:

1. A nutrient intake amount estimation system comprising:
a sensor that is disposed in a toilet space, and configured to detect an excretion smell related to excretion of a user of the toilet space;
an estimation unit configured to estimate, in accordance with an input based on an output value of the sensor, an estimated nutrient intake amount that is an amount of nutrients taken by the user by using an estimation model configured to indicate a correlation between an amount of nutrients not consumed by the user and the output value of the sensor; and
an output unit configured to output information based on the estimated nutrient intake amount.

2. The nutrient intake amount estimation system according to claim 1 , further comprising:
a storage unit configured to store a target nutrient intake amount that is a nutrient intake amount aimed at by the user, wherein
the output unit outputs the target nutrient intake amount and the estimated nutrient intake amount.

3. The nutrient intake amount estimation system according to claim 1 , further comprising:
a storage unit configured to store a target nutrient intake amount that is a nutrient intake amount aimed at by the user, wherein
the output unit outputs a difference between the target nutrient intake amount and the estimated nutrient intake amount.

4. The nutrient intake amount estimation system according to claim 3 , wherein the output unit displays recommendation information based on a difference between the target nutrient intake amount and the estimated nutrient intake amount.

5. The nutrient intake amount estimation system according to claim 2 , wherein the target nutrient intake amount stored in the storage unit is set based on selection by the user or information related to the user.

6. The nutrient intake amount estimation system according to claim 1 , wherein
the estimation unit estimates an estimated nutrient intake balance that is a balance of nutrients taken by the user as the estimated nutrient intake amount; and
the output unit outputs information based on the estimated nutrient intake balance.

7. The nutrient intake amount estimation system according to claim 1 , wherein
the estimation unit estimates an estimated specific nutrient intake amount that is an amount of a specific nutrient taken by the user as the estimated nutrient intake amount; and
the output unit outputs information based on the estimated specific nutrient intake amount.

8. The nutrient intake amount estimation system according to claim 6 , wherein the output unit displays a balance of at least two nutrients selected from carbohydrates, fat, protein, vitamins, and minerals as a graph.

9. The nutrient intake amount estimation system according to claim 1 , wherein the sensor is disposed on a toilet seat or a closet bowl in the toilet space.

10. The nutrient intake amount estimation system according to claim 1 , wherein
the estimation unit is connected to the output unit in a communicable manner via an electric communication line, and
information is transmitted from the estimation unit to the output unit via the electric communication line.

11. The nutrient intake amount estimation system according to claim 1 , further comprising:
an authentication unit configured to authenticate the user.

12. The nutrient intake amount estimation system according to claim 1 , further comprising:
a transmission unit configured to transmit data of the estimated nutrient intake amount to a terminal device via an electric communication line.

13. The nutrient intake amount estimation system according to claim 1 , wherein the excretion smell contains a smell of at least one of feces, urine, and gas excreted by the user.

14. A nutrient intake amount estimation device comprising:
an acquisition part configured to acquire an output value that is output by a sensor disposed in a toilet space after detecting an excretion smell related to excretion of a user of the toilet space; and
an estimation part configured to estimate, in accordance with an input based on an output value of the sensor, an estimated nutrient intake amount that is an amount of nutrients taken by the user by using an estimation model configured to indicate a correlation between an amount of nutrients not consumed by the user and the output value of the sensor.

15. A nutrient intake amount estimation system comprising:
a sensor that is disposed in a toilet space, and configured to detect an excretion smell related to excretion of a user of the toilet space;
an estimation unit configured to estimate, in accordance with an input based on an output value of the sensor, an estimated nutrient intake amount that is an amount of nutrients taken by the user by using an estimation model configured to indicate a correlation between an amount of nutrients not consumed by the user and the output value of the sensor.
