Apparatus and method for monitoring a driver with epilepsy using brain waves
An apparatus and method for monitoring a driver with epilepsy using a brain wave signal are disclosed. The monitoring method includes collecting a brain wave signal for a driver with epilepsy in a mobility for a predetermined time, determining the driver's state by analyzing the brain wave signal collected for the predetermined time, and controlling an operation of the mobility on the basis of the determined driver's state.
1. An apparatus for monitoring a driver with epilepsy using a brain wave signal, the apparatus comprising:
a sensor configured to collect a brain wave signal for a driver with epilepsy in a vehicle for a predetermined time;
an analyzer configured to determine the driver's state by analyzing the brain wave signal collected for the predetermined time; and
a controller configured to control an operation of the vehicle on the basis of the determined driver's state,
wherein the driver's state is determined as one of a plurality of abnormal states based on a ratio of an amplitude or power spectrum value of the brain wave signal collected from the driver to a corresponding amplitude or power spectrum value of a predefined brain wave signal of the driver, wherein the predefined brain wave signal of the driver is measured when the driver is in a normal state or a seizure state,
wherein the controller differently controls the operation of the vehicle based on each of the plurality of abnormal states, and
wherein each of the plurality of abnormal states is classified based on a corresponding ratio preset in the analyzer.
2. The apparatus of claim 1 ,
wherein the brain wave signal is at least one of a brain wave signal in a time domain or a frequency domain.
3. The apparatus of claim 1 ,
wherein the controller limits at least one of speed, power, or torque of the vehicle to a predetermined value and below on the basis of the determined driver's state among the plurality of abnormal states.
4. The apparatus of claim 1 ,
wherein the controller transmits location information of the vehicle to at least one of a preset user or a preset place, on the basis of the determined driver's state among the plurality of abnormal states.
5. The apparatus of claim 1 ,
wherein the controller stops the vehicle on the basis of the determined driver's state of the driver among the plurality of abnormal states.
6. A method of monitoring a driver with epilepsy using a brain wave signal, the method comprising:
collecting, by a sensor, a brain wave signal for a driver with epilepsy in a vehicle for a predetermined time;
determining, by an analyzer, the driver's state by analyzing the brain wave signal collected for the predetermined time; and
controlling, by a controller, an operation of the vehicle on the basis of the determined driver's state,
wherein the driver's state is determined as one of a plurality of abnormal states based on a ratio of an amplitude or power spectrum value of the brain wave signal collected from the driver to a corresponding amplitude or power spectrum value of a predefined brain wave signal of the driver, wherein the predefined brain wave signal of the driver is measured when the driver is in a normal state or a seizure state,
wherein the controller differently controls the operation of the vehicle based on each of the plurality of abnormal states, and
wherein each of the plurality of abnormal states is classified based on a corresponding ratio preset in the analyzer.
7. The method of claim 6 ,
wherein the brain wave signal is at least one of a brain wave signal in a time domain or a frequency domain.
8. The method of claim 6 ,
wherein the controlling of an operation of the vehicle comprises limiting at least one of speed, power, or torque of the vehicle to a predetermined value and below on the basis of the determined driver's state among the plurality of abnormal states.
9. The method of claim 6 ,
wherein the controlling of an operation of the vehicle comprises transmitting location information of the vehicle to at least one of a preset user and a preset place on the basis of the determined driver's state among the plurality of abnormal states.
10. The method of claim 6 ,
wherein the controlling of an operation of the vehicle comprises stopping the vehicle on the basis of the determined driver's state among the plurality of abnormal states.
