Abstract

A disclosed state display method includes: obtaining measurement results of vital activities of a subject; and displaying temporal transition of states of the subject by a one-dimensional heat map based on the measurement results. And the displaying includes: first displaying, in association with a first period in which the measurement results represent a sleep state, a first color that represents a depth of sleep by shading and has a first hue corresponding to the sleep state; and second displaying, in association with a second period in which the measurement results represent a non-sleep state, a second color that represents an intensity of an activity by the shading and has a second hue corresponding to the non-sleep state.

Claims

1. A state display method, comprising:

obtaining, by using a computer, measurement results of vital activities of a subject; and

displaying, by using the computer, a temporal transition of states of the subject in a designated time period from a first time to a second time by a one-dimensional heat map based on the measurement results, and an analysis result obtained by analyzing the states of the subject in the designated time period from the first time to the second time, wherein

the displaying comprises;

first displaying, in association with a first period in which the measurement results represent a sleep state, a first color that represents a depth of sleep by shading and has a first hue corresponding to the sleep state;

second displaying, in association with a second period in which the measurement results represent a non-sleep state, a second color that represents an intensity of an activity by the shading and has a second hue corresponding to the non-sleep state;

third displaying, upon detecting that a sleep section is longer than a non-sleep section in the designated time period from the first time to the second time, the analysis result regarding the sleep state of the subject; and

fourth displaying, upon detecting that the non-sleep section is longer than the sleep section in the designated time period from the first time to the second time, the analysis result regarding the non-sleep state of the subject.

2. The state display method as set forth in claim 1, wherein the displaying further comprises displaying, at a corresponding position, identification information for a time of at least one of moonrise, moonset, sunrise and sunset in a period displayed in the one-dimensional heat map.

3. The state display method as set forth in claim 1, wherein the displaying further comprises displaying identification information for an age of a moon in a period displayed in the one-dimensional heat map.

4. The state display method as set forth in claim 1, wherein the displaying further comprises displaying a change of outdoor temperature or indoor temperature around the subject in a period displayed in the one-dimensional heat map in a form in which a direction of an axis is different from a direction of a time axis in the one -dimensional heat map.

5. A non-transitory computer-readable storage medium storing a program that causes a computer to execute a process, the process comprising;

obtaining measurement results of vital activities of a subject; and

displaying a temporal transition of states of the subject in a designated time period from a first time to a second time by a one-dimensional heat map based on the measurement results, and an analysis result obtained by analyzing the states of the subject in the designated time period from the first time to the second time, wherein

the displaying comprises;

first displaying, in association with a first period in which the measurement results represent a sleep state, a first color that represents a depth of sleep by shading and has a first hue corresponding to the sleep state;

second displaying, in association with a second period in which the measurement results represent a non-sleep state, a second color that represents an intensity of an activity by the shading and has a second hue corresponding to the non-sleep state;

third displaying, upon detecting that a sleep section is longer than a non-sleep section in the designated time period from the first time to the second time, the analysis result regarding the sleep state of the subject; and

fourth displaying, upon detecting that the non-sleep section is longer than the sleep section in the designated time period from the first time to the second time, the analysis result regarding the non-sleep state of the subject.

6. A state display apparatus, comprising:

a memory; and

a processor coupled to the memory and configured to;

obtain measurement results of vital activities of a subject; and

display a temporal transition of states of the subject in a designated time period from a first time to a second time by a one-dimensional heat map based on the measurement results, and an analysis result obtained by analyzing the states of the subject in the designated time period from the first time to the second time, wherein

to display the temporal transition of states of the subject and the analysis result, the processor is configured to;

first render, in association with a first period in which the measurement results represent a sleep state, a first color that represents a depth of sleep by shading and has a first hue corresponding to the sleep state;

second render, in association with a second period in which the measurement results represent a non-sleep state, a second color that represents an intensity of an activity by the shading and has a second hue corresponding to the non-sleep state;

third render, upon detecting that a sleep section is longer than a non-sleep section in the designated time period from the first time to the second time, the analysis result regarding the sleep state of the subject; and

fourth render, upon detecting that the non-sleep section is longer than the sleep section in the designated time period from the first time to the second time, the analysis result regarding the non-sleep state of the subject.
