Abstract
A projection type video display device includes a video projecting unit that displays a video by projecting the video onto a video projection plane, sensors and that detect an operator who operates the projection type video display device, operation detecting units and that detect a motion of the operator based on outputs of the sensors, and a control unit that controls the video projecting unit based on a detection result of the operation detecting unit. Preferably, a sensing area in which detections by the sensors are performed when a direction of the video projection plane is vertical and is set to differ from that when the direction of the video projection plane is horizontal.
