    • A system for determining a position characteristic for an object in a room comprises an optically identifiable element (103) positioned on a background surface for a detection area of the room. A camera (101) is positioned across the detection area from the optically identifiable element (103) and captures an image comprising the detection area and the optically identifiable element (103). A detector (403) detects the optically identifiable element (103) in the image based on an optical property.
