Abstract
A method for estimating an emotional state is executed by a computer and includes acquiring an amount of change of a cerebral blood flow of a user from a reference time, acquiring an amount of change of a heart rate of the user from a reference time, and outputting a signal indicating that the user is in an excited state in a case where the amount of change of the cerebral blood flow is smaller than a first threshold value and the amount of change of the heart rate is larger than a second threshold value.
Claims13
A method executed by a computer, the method comprising:
- acquiring an amount of change of a cerebral blood flow of a user from a reference time;
- acquiring an amount of change of a heart rate of the user from a reference time;
- and
- outputting a signal indicating that the user is in an excited state in a case where the amount of change of the cerebral blood flow is smaller than a first threshold value and the amount of change of the heart rate is larger than a second threshold value.
A method executed by a computer, the method comprising:
- acquiring an amount of change of a cerebral blood flow of a user from a reference time;
- and
- outputting a signal indicating that the user is in an excited state or a relaxed state in a case where the amount of change of the cerebral blood flow is smaller than a first threshold value.
An apparatus comprising:
- a cerebral blood flow sensor that measures a cerebral blood flow of a user;
- a heart rate sensor that measures a heart rate of the user;
- and
- a signal processing circuit,
- wherein the signal processing circuit acquires an amount of change of the cerebral blood flow of the user from a reference time, acquires an amount of change of the heart rate of the user from a reference time, and outputs a signal indicating that the user is an excited state in a case where the amount of change of the cerebral blood flow is smaller than a first threshold value and the amount of change of the heart rate is larger than a second threshold value.
An apparatus comprising:
- a cerebral blood flow sensor that measures a cerebral blood flow of a user;
- and
- a signal processing circuit,
- wherein the signal processing circuit calculates an amount of change of the cerebral blood flow of the user from a reference time on a basis of a signal output from the cerebral blood flow sensor and outputs a signal indicating that the user is in an excited state or a relaxed state in a case where the amount of change of the cerebral blood flow is smaller than a first threshold value.
A non-transitory computer-readable recording medium storing a program causing a computer to:
- acquire an amount of change of a cerebral blood flow of a user from a reference time;
- acquire an amount of change of a heart rate of the user from a reference time;
- and
- output a signal indicating that the user is in an excited state in a case where the amount of change of the cerebral blood flow is smaller than a first threshold value and the amount of change of the heart rate is larger than a second threshold value.
