Abstract: A lighting control device includes a sensor that detects a state of a user and a gesture made by the user and a controller that controls a lighting characteristic of a lighting device. In the lighting control device and/or the lighting control method, it is determined (by the controller) whether a gesture made by the user and acquired by the sensor matches a first predetermined gesture including a predetermined hand shape and a predetermined movement of both hands of the user made within a detecting region between a boundary 30% larger than a periphery of a projection region illuminated by the lighting device and a boundary 30% smaller than the periphery of the projection region. When it is determined that the gesture matches the first predetermined gesture, a size of the projection region is changed (by the controller).
