Dissertação (Mestrado em Ciência da Computação) - Universidade Federal de Goiás, Goiânia, 2016.http://repositorio.bc.ufg.br/tede/handle/tede/5925The consumption of alcohol beverages causes disturbance to society, such as traffic accidents, problems at work and interpersonal violence. The main methods for the detection of alcohol are the use of a breathalyzer and a blood test. Such methods are, however, relatively invasive. The purpose of this work is to develop a portable device and a method capable of performing the dynamic pupillometry to verify the feasibility of detect alcohol use by means of recording pupillary movements under light stimulation. After the device creation, was recorded and collected biometric information of 49 people in sober and inebriated state, producing a database with 356 video. So were selected the most relevant pupillary features. This set of features was subjected to statistical tests and pattern recognition algorithms KNN, Ensemble KNN and SVM. The results showed that pupillometry was performed efficiently with 96% accuracy, the alcohol changes the pupillary behavior and detecting alcohol consumption is feasible when the analysis is done individually and with many videos.application/pdfAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/PupilômetroPupilometriaPupilaIrisÁlcoolÁlcool no sanguePupillometerPupillometryPupilIrisAlcoholBlood alcohol detectionCIENCIA DA COMPUTACAO::METODOLOGIA E TECNICAS DA COMPUTACAODissertação
