Abstract
The present disclosure provides a system and method for monitoring the cognitive state of a patient based on eye image data. The patient monitoring system including a camera unit configured for recording images of an eye of the patient, and a data processing sub-system in data communication with the camera and being operable to (i) receive and process eye image data from the camera, (ii) classify the eye image data into gestures and identify such gestures indicative of the cognitive state of the patient, and (iii) transmit a signal communicating the cognitive state to a remote unit. The system may further include an actuator module and an output unit wherein the output may be an automated medical questionnaire.
Claims18
A patient monitoring system for identifying a cognitive state of a patient, the system comprising
- a camera unit configured for recording images of an eye of the patient;
- a data processing sub-system in data communication with the camera and being operable to
- i. receive and process eye image data from said camera;
- ii. classify said eye image data into gestures and identify such gestures that are indicative of the cognitive state of the patient to thereby predict a cognitive state of the patient, and
- iii. transmit a signal communicating said cognitive state to a remote unit;
- a processing circuitry;
- and
- an output unit;
- wherein said processing circuitry is configured to operate said output unit to present an output to the patient;
- wherein said output comprises media content that comprises any visual or auditory content, the media content being selected based on the predicted cognitive state by the system to thereby positively affect the patient's cognitive state;
- wherein said output further comprises one or more questions and instructions to the patient on how to respond to the one or more questions by using eye gestures, and the one or more questions are output following said output of media content, wherein the instructions specify how to use eye gestures to indicate specific responses to each question;
- and
- wherein said data processing sub-system records reactive image data representative of a reactive eye movement that follows said output, classify said reactive image data into reactive gestures and identifying such gestures being indicative of the cognitive state of the patient to determine an updated cognitive state of the subject following said output.

A patient monitoring method for identifying a cognitive state of a patient, the method comprising
- a. recording image data of at least one of patient's eyes;
- b. classifying said image data into gestures;
- c. identifying such gestures that are indicative of the cognitive state of the patient;
- transmitting a signal communicating said cognitive state to a remote unit;
- d. providing an output to the patient that comprises media content that comprises any visual or auditory content, the media content being selected based on the predicted cognitive state by the system to thereby positively affect the patient's cognitive state, wherein said output further comprises one or more questions and instructions to the patient how to respond to the one or more questions by using eye gestures, and the one or more questions are output following said output of media content, wherein the instructions specify how to use eye gestures to indicate specific responses to each question;
- e. recording reactive image data representative of a reactive eye movement that follows said output;
- f. classifying said reactive image data into reactive gestures;
- and
- g. identifying such gestures indicative of the cognitive state of the patient to determine an updated cognitive state of the subject following said output.

- wherein said output comprises media content that comprises auditory content, the media content being selected based on the predicted cognitive state by the system to thereby positively affect the patient's cognitive state;
- wherein the media content comprises voices of family members;
- wherein said output further comprises one or more questions and instructions to the patient on how to respond to the one or more questions by using eye gestures, and the one or more questions are output following said output of media content, wherein the instructions specify how to use eye gestures to indicate specific responses to each question;
- and
- wherein said data processing sub-system records reactive image data representative of a reactive eye movement that follows said output, classify said reactive image data into reactive gestures and identifying such gestures being indicative of the cognitive state of the patient to determine an updated cognitive state of the subject following said output;
- wherein the cognitive state is selected from wakefulness, delirium, cognitive decline, confusion, disorientation, abnormal attention, consciousness.
