Drowsiness detection method and associated device

摘要

A drowsiness detection method for detecting drowsiness of a detection target is provided. The method includes a data collecting process including steps of: detecting physiological symptom information of the detection target; determining whether the detection target satisfies a predetermined drowsiness threshold condition according to the physiological symptom information; when the detection target satisfies the predetermined drowsiness threshold condition, triggering a stimulation event on the detection target; determining whether a response event is received from the detection target in response to the stimulation event; when the response event is not received, determining whether the stimulation event satisfies a threshold strength condition; and recording the physiological symptom information as a corresponding drowsiness detection condition of the detection target when the stimulation event satisfies the threshold strength condition.

1. A drowsiness detection method, for performing a drowsiness detection operation on a detection target, the drowsiness detection method comprising a data collecting process, the data collecting process comprising:
a) detecting, by a detection/control circuit, first brainwave symptom information of the detection target; b) determining, by the detection/control circuit, whether the detection target satisfies a predetermined drowsiness threshold condition according to the first brainwave symptom information, and performing Step (c) if a result is affirmative; c) triggering, by a simulation triggering circuit connected to the detection/control circuit, a stimulation event on the detection target in response to a driving signal provided by the detection/control circuit when the detection target satisfies the predetermined drowsiness threshold condition; d) within a predetermined period after step (c), determining, by a response circuit connected to the detection/control circuit, whether a response event, triggered by the detection target in response to the stimulation event, is detected, wherein in response to the response event the response circuit provides a response signal to the detection/control circuit and the response event is a man-machine-interface response event; e) determining, by the detection/control circuit, whether the stimulation event satisfies a threshold strength condition when the response event is not detected; f) recording, by the detection/control circuit, the first brainwave symptom information as a drowsiness detection condition corresponding to the detection target when the stimulation event satisfies the threshold strength condition; and g) increasing, by the detection/control circuit, a strength of the stimulation event when the stimulation event does not satisfy the threshold strength condition, and iterating step (c); wherein the data collecting process further comprises adjusting the threshold strength condition and iterating steps (a) to (g) to obtain a plurality of the drowsiness detection conditions corresponding to different threshold strength conditions of the detection target.
