연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Method and systems are disclosed for training state-classifiers for classification of cognitive state. A set of multimodal signals indicating physiological responses of an operator are sampled over a time period. A depiction of operation by the operator during the time period is displayed. In response to user input selecting a cognitive state for a portion of the time period, the one or more state-classifiers are trained. In training the state-classifiers, the set of multimodal signals sampled in the portion of the time period are used as input to the on...

1. A system, comprising: a set of sensors configured to provide a set of multimodal signals indicating physiological responses of an operator, of a vehicle or device, to stimuli in a first time period;a processing circuit configured to train one or more state-classifiers to map the set of multimodal signals to a set of cognitive states; anda display configured to depict operation of the vehicle or device by the operator in the first time period;a data storage circuit coupled to the processing circuit and configured to store the one or more state-classifiers;a second processing circuit coupled to the data storage and configured to determine a cognitive state of an operator using the one or more state-classifiers and the set of multimodal signals as input to the one or more state-classifiers;a third processing circuit configured to perform an action specified in a settings file, stored in the data storage, in response to the determined cognitive state of the operator satisfying a set of criteria specified in the settings file;wherein the action specified in the settings file includes at least one of a set of actions including adjusting operation of the vehicle or device, providing an alert to the operator, and sending an alert message; andwherein the processing circuit is further configured to, in response to user input selecting one of the set of cognitive states and a portion of the first time period, perform the training of the one or more state-classifiers using the set of multimodal signals sampled in the portion of the time period as input to the one or more state-classifiers and the selected one of the set of cognitive states as a target result to be mapped to by the one or more state-classifiers. 2. The system of claim 1, further comprising a second display configured to provide the stimuli configured to induce a set of cognitive states in the operator. 3. The system of claim 1, further comprising a circuit coupled to the set of sensors and configured to sample outputs of the set of sensors to produce the set of multimodal signals. 4. The system of claim 1, wherein the display is configured to provide a graphical user interface for selection of the portion of the time period and selection of the one of the set of cognitive states. 5. The system of claim 1, wherein the third processing circuit is configured to: determine a level of confidence in the cognitive state determined by second processing circuit; andin response to the level of confidence being less than a threshold level specified in the set of criteria, cause the first-mentioned processing circuit to retrain the one or more state-classifiers. 6. The system of claim 1, wherein in response to a first user input, the third processing circuit is configured to provide automated feedback to the operator in further response to the determined cognitive state of the operator being a performance limiting cognitive state; andin response to a second user input, the third processing circuit is configured to disable the automated feedback to the operator. 7. The system of claim 1, wherein the third processing circuit is configured to trigger an audible alert or engage an autonomous driving system of the vehicle in response to the determined cognitive state of the operator indicating the operator is in an inattentive or unresponsive cognitive state. 8. A method, comprising: sampling a set of multimodal signals indicating physiological responses of an operator of a vehicle or device over a time period;retrieving one or more state-classifiers from a data storage, wherein the one or more state-classifiers are configured to map the set of multimodal signals to a set of cognitive states;determining respective probabilities of the operator being in the set of cognitive states using the sampled set of multimodal signals as input to the one or more state-classifiers; andin response to the determined respective probabilities satisfying a set of criteria stored in a settings file performing one or more of a set of actions including adjusting operation of the vehicle or device, providing an alert to the operator, or sending an alert message. 9. The method of claim 8, wherein the performing of one or more of the set of actions provides an audible alert to the operator or engages an autonomous driving system of the vehicle and is performed in response to the determined respective probabilities indicating the operator is in an inattentive or unresponsive cognitive state. 10. The method of claim 8, wherein the performing of one or more of the set of actions prevents operation of the vehicle and is performed in response to the determined respective probabilities indicating the operator is in a cognitive state indicative of the operator being under an influence of alcohol. 11.
