System and method to detect alertness of machine operator
A system and method relate to receiving, by a processing device, at least one stream of data captured by at least one sensor monitoring a human subject, wherein the at least one stream of data comprises sensor measurements, comparing the sensor measurements to at least one model of a mental state to estimate the mental state of the human subject, determining whether to trigger an alarm based on the estimated mental state, and in response to determining to trigger the alarm, generating an instruction to trigger the alarm.
1. A method comprising:
receiving, by a processing device, at least one stream of data captured by at least one sensor monitoring a human subject, wherein the at least one stream of data comprises sensor measurements;
comparing the sensor measurements to at a threshold to determine whether the human subject is at least one of drowsy or intoxicated;
determining whether to trigger an alarm based on the comparison; and
in response to determining to trigger the alarm, generating an instruction to trigger the alarm.
2. The method of claim 1 , wherein the at least one sensor comprises at least one of a brain wave monitor, a sleep monitor, a camera, a breath analyzer, a health monitor, an accelerometer, or an environmental monitor.
3. The method of claim 2 , wherein the brain wave monitor comprises an electroencephalography (EEG) monitor, and wherein the EEG monitor is to measure voltage potentials on scalp of the human subject.
4. The method of claim 2 , wherein the sleep monitor comprises an electromyography (EMG) monitor, and wherein the EMG monitor is to measure an electrical activity caused by eye blinks by the human subject.
5. The method of claim 2 , wherein the accelerometer is to measure an acceleration of a head nod by the human subject.
6. The method of claim 2 , wherein the health monitor comprises a heart rate monitor, and wherein the heart rate monitor is to measure a heart rate of the human subject.
7. The method of claim 1 , wherein the human subject is a truck driver driving a truck.
8. The method of claim 1 , further comprising:
transmitting the instruction to trigger the alarm to an alarm receiver, wherein, in response to receiving the instruction, the alarm receiver is to generate the alarm.
9. The method of claim 8 , wherein the alarm comprises at least one of a sound alarm, a flash light, or a vibration.
10. The method of claim 1 , wherein the at least one model is built using machine learning.
11. A non-transitory machine-readable storage medium storing instructions which, when executed, cause a processing device to:
receive, by the processing device, at least one stream of data captured by at least one sensor monitoring a human subject, wherein the at least one stream of data comprises sensor measurements;
comparing the sensor measurements to at a threshold to determine whether the human subject is at least one of drowsy or intoxicated;
determining whether to trigger an alarm based on the comparison; and
in response to determining to trigger the alarm, generating an instruction to trigger the alarm.
12. A wearable device comprising:
an electroencephalography (EEG) sensor to detect a brain wave data of a human subject;
a heart rate sensor to detect a heart rate data of the human subject;
an electromyography (EMG) sensor to detect an electrical activity data relating to eye blinks by the human subject;
an accelerometer to detect an acceleration data of the human subject; and
a warning device to generate an alarm in response to determining the human subject is at least one of drowsy or intoxicated based on at least one of the brain wave data, the heart rate data, the electrical activity data, or the acceleration data and associated thresholds.
13. The wearable device of claim 12 , wherein the wearable device is a headband mountable on a head of the human subject.
14. The wearable device of claim 13 , wherein the human subject is a machine operator operating a machine.
15. The wearable device of claim 12 , wherein the mental state comprises one of a drowsiness state, an intoxication state, a rage state, a depression state, or a meditative state.
16. The wearable device of claim 12 , further comprising:
communication device to transmit the at least one of the brain wave data, the heart rate data, the electrical activity data, or the acceleration data to a processing device, wherein the communication device receives an indication indicating the occurrence of the mental state.
17. The wearable device of claim 16 , wherein in response to receiving the indication indicating the occurrence of the mental state, the communication device is to transmit an instruction to the warning device.
18. The wearable device of claim 17 , wherein in response to receiving the instruction from the communication device, the warning device is to generate the alarm.
19. The wearable device of claim 18 , wherein the alarm comprises at least one of a sound alarm, a flash light, or a vibration.
