Embodiment

[0069] In order to test the performance of this method, this method is written as an Android application and deployed in different models of Android phones. And recruited 6 drivers (4 males and 2 females) to drive different vehicles for a 2-month experiment. During the experiment, the driver carried out the experiment completely in accordance with the usual smoking habits and driving habits.

[0070] Drivers vary in their smoking patterns and driving habits, so we first tested the overall accuracy of the method in various situations. Six drivers conducted experiments according to their own smoking habits during daily driving, and the mobile phone in the car analyzed the driver's sports behavior. image 3 Experimental results while driving with different drivers are shown. The accuracy rate of detection refers to the ratio of the number of correct detections by this method to the total number of times the driver actually exhibited the behavior for a certain behavior; the fals...

Abstract

The invention relates to a method for detecting a driver's smoking behavior by using a smart phone speaker and a microphone, and belongs to the technical field of mobile computing applications. A simple active sonar system is composed of speakers and microphones commonly equipped with existing smartphones. The ultrasonic waves emitted by the speaker of the mobile phone are reflected by obstacles at different distances and received by the microphone of the mobile phone at different times. When the driver smokes, the movement of his arm and chest has a certain regularity, and the system analyzes whether there is smoking behavior by detecting the movement of the driver's arm and chest. The method of the present invention is especially suitable for driving environments where smoking is prohibited, such as taxis, online car-hailing and buses.

Description

technical field [0001] The invention relates to a method for detecting a driver's smoking behavior, in particular to a method for detecting a driver's smoking behavior using a smart phone speaker and a microphone, which is used to detect whether a driver has a smoking behavior, and belongs to the technical field of mobile computing applications. Background technique [0002] With the continuous expansion of cities, people's dependence on cars in daily life and work has also increased rapidly, and road safety problems have become more and more serious. An important cause of traffic accidents is the driver's distracted driving behavior during vehicle driving. Studies have shown that 90% of traffic accidents caused by distracted driving are related to drivers smoking. In addition to road safety issues, smoking in the car will also affect the health of the occupants. Another study found that toxin levels were 11 times higher in cars that were regularly smoked than in bars. Sm...
