A steerable viewing system and an associated method of operation are disclosed. The system comprises a steerable filter for placing in front of a display area of a display device and a controller for causing the steerable filter to define one or more viewing passages extending through the steerable filter and permitting viewing of the display area from a first position through the steerable filter and one or more viewing barriers preventing viewing of the display area from a second position different from the first position through the steerable filter. The viewing passages are defined by LCD elements of the steerable filter in the transmissive state. The viewing barriers are defined by LCD elements of the steerable filter in the light-blocking state.
