The user interface enables light characteristics of the lighting system 100 to be adjusted such as the light color emitted from a light source 110 of the lighting system 100. A monitor 130 is provided for monitoring how the patient interacts with the user interface 120, e.g. by monitoring how frequent the patient interacts with the user interface, the monitored number of interactions may be processed by a processor 140 to determine a value of the coping style which indicates how active or passive the patient is. ## Claims ### Claim 1 A lighting system, comprising: a light source that is directly controllable by a user to generate selected light characteristics from a plurality of selectable light characteristics, a user interface that enables the user to directly control the light source to concurrently produce a desired set of light characteristics, and a monitor that monitors interactions of a user with the user interface, wherein the user interface is configured to modify the light characteristics that are selectable by the user, based on previous interactions of the user with the user interface, and where the lighting system comprises an output for communicating the monitored interaction of the user with the user interface to a processing unit that determines a condition of the user from the monitored interaction of the user with the user interface. ### Claim 2 (depends on 1) The lighting system of claim 1, wherein the selectable light characteristics include light color characteristics. ### Claim 3 (depends on 1) The lighting system of claim 1, wherein the monitor is configured to monitor one or more of the following parameters: a period of time when a user selects the desired light characteristics from the user interface, a duration of a key press, a pressure exerted on a button for selecting the desired light characteristic, a number of selections of light characteristics of the user interface, a finally selected desired light characteristic, a similarity of presently selected desired light characteristics with previously selected desired light characteristics, and motion of the user interface. ### Claim 4 (depends on 1) The lighting system of claim 1, wherein the monitor comprises a camera that monitors interaction of the user with the user interface. ### Claim 5 (depends on 1) The lighting system of claim 1, where the light source is a LED lamp. ### Claim 6 (depends on 1) A patient monitoring system comprising: the lighting system of claim 1, a processing unit that includes a patient prediction function that determines a condition of a patient based on the patient's interaction with the user interface. ### Claim 7 (depends on 6) The patient monitoring system of claim 6, wherein the processing unit modifies the patient prediction function based on a comparison of the patient condition determined by the processing unit and a known patient condition. ### Claim 8 A method for determining a patient condition, comprising: providing a user interface that enables a patient to directly control a light source to concurrently provide a select set of characteristics of the light source from a plurality of characteristics that are selectable by the patient, monitoring selections of the patient on the user interface that produce a desired set of characteristics of the light source, processing the monitored selections so as to determine the patient condition, and modifying the characteristics that are selectable by the patient, based on previous interactions of the patient with the user interface. ### Claim 9 (depends on 8) The method of claim 8, where the characteristics that are selectable by the patient includes light color characteristics. ### Claim 10 (depends on 8) The method of claim 8, wherein the processing of the monitored selections is performed at a processing unit that is external to the light source, and the method includes communicating the monitored selections to the processing unit. ### Claim 11 (depends on 8) The method of claim 8, wherein the monitoring of the selections is performed at a processing unit that is external to the light source. ### Claim 12 (depends on 8) The method of claim 8, wherein the monitoring of the selections includes monitoring camera images of the user with the user interface. ### Claim 13 (depends on 8) The method of claim 8, wherein the monitoring of the selections includes monitoring one or more of the following parameters: a period of time when the patient selects the desired set of characteristics from the user interface; a duration of a key press; a pressure exerted on a button for selecting a characteristic of the desired set of characteristics; a number of selections of characteristics of the light source; a finally selected desired characteristic; a similarity of presently selected desired characteristics with previously selected desired characteristics; and motion of the user interface.
