wherein the controller specifies at least one image of the plurality of aerial images as a command target by detecting overlapping between an outer edge of the at least one image of the plurality of aerial images and a part of an object.

6. The information processing device according to claim 5 ,

wherein the controller sets the overlapping for a predetermined time period or longer as a detection target.

7. The information processing device according to claim 1 ,

wherein the controller specifies at least one image of the plurality of aerial images as a command target by performing image-processing on a gesture of the user.

8. The information processing device according to claim 1 ,

wherein the controller specifies at least one image of the plurality of aerial images as a command target by recognizing a voice of the user.

9. The information processing device according to claim 1 ,

wherein the controller shifts one or more of the plurality of aerial images designated by the user to a position at the front side.

10. The information processing device according to claim 1 ,

wherein, of the images displayed at respective positions in an arrangement direction, the controller excludes, from the display, a section that overlaps with a display of an object displayed at the respective positions at the front side.

11. The information processing device according to claim 1 ,

wherein, of the images displayed at respective positions in an arrangement direction, the controller decreases brightness of a section that overlaps with a display of an object displayed at the respective positions at the front side.

12. The information processing device according to claim 1 ,

wherein, in a case where one or more of the plurality of aerial images designated by the user are deleted, the controller adjusts a position of a remaining one or more of the plurality of aerial images in the depth direction.

13. The information processing device according to claim 1 ,

wherein, in a case where one or more of the images designated by the user are deleted, the controller expands a display of an object included in a remaining one or more of the plurality of aerial images.

14. The information processing device according to claim 1 ,

wherein, in a case where one or more of the images are inserted, the controller reduces arrangement spacing in the depth direction.

15. The information processing device according to claim 1 ,

wherein, in a case where one or more of the plurality of aerial images are inserted, the controller reduces a display of an object included in each image.

16. An information processing device comprising:

a controller configured to:

control each of a plurality of image forming devices to display an image, each image being displayed at a position, in a depth direction, of a plurality of aerial images formed as floating images in air, and being arranged in overlapping layers with each other when viewed by a user in a depth direction from a front-most layer of the floating images to a back-most layer of the floating images,

wherein each of the aerial images is formed by a separate image forming device of the plurality of image forming devices, and each aerial image is displayed in a different position in the air, in an arranged order in the depth direction; and

in response to a command from a user, control to change, in the depth direction, the arranged order of at least one image of the plurality of aerial images by interchanging image data of an aerial image that is transmitted to one of the plurality of image forming devices with image data of another aerial image that is transmitted to another of the plurality of image forming devices.

17. An information processing system comprising:

a plurality of image forming units, each image forming unit being configured to form an image in air; and

a controller configured to:

control each of a plurality of image forming devices to display an image, each image being one of a plurality of aerial images formed as floating images in air and being arranged in overlapping layers with each other when viewed by a user in a depth direction from a front-most layer of the floating images to a back-most layer of the floating images,

wherein each of the aerial images is formed by a separate image forming device of the plurality of image forming devices, and each aerial image is displayed in a different position in the air, in an arranged order in the depth direction; and

in response to a command from a user, control to change, in the depth direction, the arranged order of at least one image of the plurality of aerial images by interchanging image data of an aerial image that is transmitted to one of the plurality of image forming devices with image data of another aerial image that is transmitted to another of the plurality of image forming devices.

18. The information processing system according to claim 17 ,

wherein one image forming unit of the plurality of image forming devices forms the plurality of aerial images at different positions in a time-sharing manner.

19. A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

controlling each of a plurality of image forming devices to display an image, each image being one of a plurality of aerial images formed as floating images in air and being arranged in overlapping layers with each other when viewed by a user in a depth direction from a front-most layer of the floating images to a back-most layer of the floating images;

displaying each of the aerial images in a different position in the air, in an arranged order in a depth direction, each of the aerial images being formed by a separate image forming device of a plurality of image forming devices; and
