Projector device
A projector device includes a distance detector, an imaging unit, a projector unit, a driver, and a controller. The imaging unit detects a specific target object. The projector unit projects a projection image. The driver drives the projector unit such that a projection direction in which the projection image is to be projected is changed. The distance detector detects a state of the target object detected by the imaging unit. The controller controls at least one of the projector unit and the driver such that the projection image tracks the target object. The projection image has display data including a content for guiding the target object. The controller changes a content of information included in the display data in the projection image, which is to be projected while tracking the target object, according to the state of the target object detected by the distance detector.
1. A projector device comprising:
a first detector that detects a specific target object;
a projector unit that projects a projection image;
a driver that drives the projector unit such that a projection direction in which the projection image is to be projected is changed;
a second detector that detects a movement vector of the target object detected by the first detector;
a controller that controls at least one of the projector unit and the driver such that the projection image tracks the target object; and
a memory that stores a table including a predetermined speed information of the movement vector of the target object and contents data corresponding to a speed information, the contents data including text data and image data,
wherein
the projection image includes guidance information having a content for guiding the target object, and
the controller changes a content of information included in the guidance information in the projection image, which is to be projected while tracking the target object, according to the movement vector of the target object detected by the second detector, and
wherein
the controller sets the text data in the projection image when a speed of the movement vector of the target object is lower than a predetermined speed, and
the controller sets the image data in the projection image when the speed of the movement vector of the target object is equal to or higher than the predetermined speed.
2. The projector device according to claim 1 , wherein
the controller sets the guidance information in the projection image, which is to be projected while tracking the target object, to a content including text data indicating a detailed guidance content, when a speed of the movement vector of the target object is lower than a predetermined speed, and
the controller sets the guidance information in the projection image, which is to be projected while tracking the target object, to image data, when the speed of the movement vector of the target object is equal to or higher than the predetermined speed.
3. The projector device according to claim 1 , wherein
when the movement vector of the target object has an orientation approaching the second detector, the controller causes the projector unit to project the projection image having guidance information for leading the target object.
4. The projector device according to claim 1 , wherein
when the movement vector of the target object has an orientation away from the second detector, the controller causes the projector unit to project the projection image having guidance information with a content for attracting attention of the target object.
5. The projector device according to claim 1 , wherein
at least one of the first detector and the second detector includes a distance detector that detects a distance between the distance detector and the target object.
6. The projector device according to claim 1 , wherein
at least one of the first detector and the second detector includes an camera that captures an image of the target object.
