The monitoring system comprises a range detection system configured for scanning a scene to provide range data, the range data including data describing range to a marker that is detectable by the range detection system and that is placed on a hand of an individual in the scene; and a data processing system configured for processing the range data to identify the marker, to identify the hand based, at least in part on the range to the marker, and to monitor hygienic activity of an individual in the scene. ## Claims ### Claim 1 A monitoring system, comprising: a range detection system configured for scanning a scene to provide range data arranged gridwise over a plurality of picture elements which are devoid of any color data and any grayscale data, said range data including data describing range to a marker that is detectable by said range detection system and that is placed on a hand of an individual in said scene; and a data processing system configured for processing said range data to identify said marker, to identify said hand based, at least in part on said range to said marker, to identify points of contact between said individual and objects in said scene, and to monitor hygienic activity of an individual in said scene. ### Claim 2 (depends on 1) The system according to claim 1, wherein said range detection system scans said scene from a single view point. ### Claim 3 (depends on 1) The system according to claim 1, wherein said range detection system provides range imaging data, and said data processing system is configured for removing from each picture-element any color data or grayscale data that allow identifying any individual in said scene. ### Claim 4 (depends on 1) The system according to claim 1, wherein said data processing system is configured to identify a medical treatment device in said scene, and contact events between said individual and said medical treatment device, and to determine a time window encompassing both said hygienic activity and said contact events. ### Claim 5 (depends on 1) The system according to claim 1, wherein said data processing system is configured to identify contact events between said individual and an organ of a patient in said scene, and to issue a notification when said contact events are not preceded or not followed by said hygienic activity. ### Claim 6 (depends on 1) The system according to claim 1, further comprising an electromagnetic signaling system configured to project a light beam on said individual or an object in said scene based on said hygienic activity or lack thereof. ### Claim 7 (depends on 1) The system according to claim 1, comprising an electromagnetic disinfecting system configured to project a disinfecting light beam on at least one of said points of contact. ### Claim 8 A method of monitoring, comprising: scanning a scene to provide range data to a marker that is placed on a hand of an individual in said scene, the range data being arranged gridwise over a plurality of picture elements which are devoid of any color data and any grayscale data; and processing said range data to identify said hand based, at least in part on said range to said marker, to identify points of contact between said individual and objects in said scene, and to monitor hygienic activity of an individual in said scene. ### Claim 9 (depends on 8) The method according to claim 8, wherein said scanning is from a single view point. ### Claim 10 (depends on 8) The method according to claim 8, further comprising identifying a medical treatment device in said scene and contact events between said individual and said medical treatment device, and determining a time window encompassing both said hygienic activity and said contact events. ### Claim 11 (depends on 8) The method according to claim 8, further comprising issuing a notification when said contact events are not preceded or not followed by said hygienic activity. ### Claim 12 (depends on 8) The method according to claim 8, further comprising projecting a light beam on said individual or an object in said scene based on said hygienic activity or lack thereof. ### Claim 13 (depends on 8) The method according to claim 8, further comprising projecting a disinfecting light beam on at least one of said points of contact. ### Claim 14 A method of monitoring, comprising: scanning a scene and provide range data including data describing a range to a hand of an individual in said scene and data describing a location of said individual within said scene, the range data being arranged gridwise over a plurality of picture elements which are devoid of any color data and any grayscale data; and correction said data describing said range to said hand based, at least in part on said data describing said location of said individual within said scene. ### Claim 15 (depends on 14) The method according to claim 14, further comprising processing said corrected data to monitor hygienic activity of an individual in said scene. ### Claim 16 (depends on 14) The method according to claim 14, further comprising determining at least one of a posture and an orientation of said individual, wherein said correction is based, at least in part, on at least one of said posture and orientation. ### Claim 17 (depends on 14) The method according to claim 14, further comprising identifying contact events between said individual and an organ of a patient in said scene, and issuing a notification when said contact events are not preceded or not followed by said hygienic activity. ### Claim 18 (depends on 14) The method according to claim 14, further comprising projecting a light beam on said individual or an object in said scene based on said hygienic activity or lack thereof. ### Claim 19 (depends on 14) The method according to claim 14, further comprising identifying points of contact between said individual and objects in said scene, and projecting a disinfecting light beam on at least one of said points of contact.
