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).

Lighting control device, lighting system, and method of controlling lighting device

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 one or more lighting devices. In the lighting control device and in a method of controlling the lighting device, the sensor detects a first state and a second state of a hand of the user. In response to the sensor detecting the hand of the user in the first state aiming at one lighting device among the one or more lighting devices, the controller designates the one lighting device as a control target lighting device, and in response to the sensor detecting a predetermined gesture involving the hand in the second state, the controller controls a lighting characteristic of the control target lighting device.
