Abstract
A processor of a fluctuation detection device that detects fluctuation of a body of a user, is configured to measure a first distance that is a distance to a still object existing in a first direction and a second distance that is a distance to a still object existing in a second direction different from the first direction, to calculate a first fluctuation amount that is a changing amount of the first distance and a second fluctuation amount that is a changing amount of the second distance, and to remove a changing amount of the first distance caused by breathing of the user from the first fluctuation amount and to remove a changing amount of the second distance caused by the breathing from the second fluctuation amount.
Claims9
A fluctuation detection device that detects fluctuation of a body of a user, the fluctuation detection device comprising:
- a processor configured to measure a first distance that is a distance to a still object existing in a first direction and a second distance that is a distance to a still object existing in a second direction different from the first direction, to calculate a first fluctuation amount that is a changing amount of the first distance and a second fluctuation amount that is a changing amount of the second distance, and to remove a changing amount of the first distance caused by breathing of the user from the first fluctuation amount and to remove a changing amount of the second distance caused by the breathing from the second fluctuation amount.
A fluctuation detection method that detects fluctuation of a body of a user, the fluctuation detection method comprising:
- measuring, by a processor, a first distance that is a distance to a still object existing in a first direction and a second distance that is a distance to a still object existing in a second direction different from the first direction;
- calculating, by the processor, a first fluctuation amount that is a changing amount of the first distance and a second fluctuation amount that is a changing amount of the second distance;
- detecting, by the processor, breathing of the user;
- and
- removing, by the processor, a changing amount of the first distance caused by the breathing from the first fluctuation amount and removing a changing amount of the second distance caused by the breathing from the second fluctuation amount when breathing of the user is detected during the measurement.
A computer-readable recording medium having stored therein a program for causing a computer to execute a process for detecting fluctuation of a body of a user, the process comprising:
- measuring a first distance that is a distance to a still object existing in a first direction and a second distance that is a distance to a still object existing in a second direction different from the first direction;
- calculating a first fluctuation amount that is a changing amount of the first distance and a second fluctuation amount that is a changing amount of the second distance;
- detecting breathing of the user;
- and
- removing a changing amount of the first distance caused by the breathing from the first fluctuation amount and removing a changing amount of the second distance caused by the breathing from the second fluctuation amount when breathing of the user is detected during the measurement.
