On August 18, according to foreign media reports, a new study from the magazine shows that scientists can detect people’s walking patterns through smart phones to determine whether they are drunk or not. < / P > < p > now people almost always take their smartphones when they go out. Therefore, scientists try to develop a method based on smart phones that can detect whether people drink too much in real time. < / P > < p > in this study, the researchers recruited 22 adults aged between 21 and 43. In the laboratory, the subjects received a mixed drink containing enough vodka to produce an alcohol concentration of 0.20%. The subjects had to finish drinking within an hour. < p > < p > then, the exhaled alcohol concentration and walking style of the subjects were analyzed every 7 hours. In the test, the subject placed the smartphone under his back and fixed it, walked 10 steps along a straight line, turned around, and walked another 10 steps. The acceleration and medial lateral, vertical and anteroposterior motions of the subjects were measured by the smartphone. About 90 percent of the time, researchers were able to use gait changes to determine when the subjects exhaled more than 0.08 percent of the time. < / P > < p > the researchers said that research shows that we can identify whether people are drunk by using mobile phones. Since people normally don’t put their phones under their backs, we plan to test them in their hands and pockets to see if the method works. Huawei has finally made a choice!
