Abstract
Methods and systems for indicating boundaries of a volume of space are disclosed. A method may include: providing a first pair of indicators positioned to visually indicate boundaries of a predefined volume of space with respect to a first axis; providing a second pair of indicators positioned to visually indicate boundaries of the predefined volume of space with respect to a second axis; and configuring the first pair of indicators and the second pair of indicators to provide a first type of visual indication visible to a viewer from positions outside of the predefined volume of space. The methods and systems may be utilized for indicating boundaries of a volume of space for proper and/or improper viewing of a display device.
