Methods and systems consistent with some embodiments presented provide methods for denying visual access to a first area from a target area. In some embodiments, methods for denying visual access from a target area may include generating a structured light pattern and projecting the structured light pattern from onto the target area. The structured light pattern may be moved at a rate and in a pattern to deny visual access of a first area from the target area. In some embodiments, the rate and the pattern may be chosen based on characteristics of the target area.
