The present disclosure provides solutions for monitoring the sedation/cognitive state of a patient, such as an Intensive Care Unit (ICU) patient, that can be found in a plurality of sedation/cognitive states, ranging from non-responsive states to fully responsive and providing a selected interaction that is suitable for the determined state in order to optimize the interaction with the patient and, optionally, to improve his/her sedation state. The determination of the sedation state of the patient can be made by one or more sensing devices or input utilities, such as eye tracking sensor, EEG sensor or any applicable user interface.
