An illumination system for a room, comprising: a light assembly comprising at least one illumination source configured to selectively direct at least one light emission in an operating region of the room; an imager configured to capture image data in a field of view in the room; a controller in communication with the light assembly and the imager, wherein the controller is configured to: detect a position of a marker in the image data; control the light assembly to direct the at least one light emission (80, 82) within the operating region based on the position of the marker; characterised in that - the at least one light emission comprises a first light emission and a second light emission; and - the controller is further configured to: selectively control a first target location of a first lighting region of the first light emission in response to identifying the marker proximate to the first lighting region for a predetermined period of time, wherein the selective control of the first target location includes adjusting the first target location by tracking the position of the marker; and selectively control a second target location of a second lighting region of the second light emission in response to identifying the marker proximate to the second lighting region for a predetermined period of time, wherein the selective control of the first target location and the second target location includes controlling the first target location of the first lighting region or the second target location of the second lighting region to change commensurate to the motion of the marker within the operating region. a light assembly comprising at least one illumination source configured to selectively direct at least one light emission in an operating region of the room;
