Abstract
Various arrangements for defining a marker are presented. A first defined marker presented by a public display device may be determined to be insufficient for use by a head mounted display. The first defined marker may be used as a reference point for positioning information for display by the head mounted display. In response to determining that the first defined marker is insufficient, a second marker displayed by the public display device may be defined. The second marker may have a display characteristic different from the first defined marker. The second defined marker may then be used as the reference point for positioning the information for display by the head mounted display. An indication of the second marker may be transmitted to the head mounted display.
