12. The controlling device according to claim 1 ,
wherein the processor obtains information regarding a position of the object detected by a detector.
13. The controlling device according to claim 1 ,
wherein the processor obtains information regarding a position of an eye of the user detected by a detector and cause the display device to display the second display based on the position of the eye of the user.
14. The controlling device according to claim 1 ,
wherein the processor controls the display device to display the second display at a position that is the same as the first display in a direction from the first display toward the user.
15. The controlling device according to claim 1 ,
wherein the processor controls the display device to display the second display at a position that is different from the first display in a direction from the first display toward the user.
16. The controlling device according to claim 1 ,
wherein the object is a hand or a finger of the user.
17. The controlling device according to claim 16 ,
wherein the first display is operated by the hand or the finger of the user.
18. The controlling device according to claim 1 ,
wherein the processor controls the display device to display the second display in midair.
19. The controlling device according to claim 18 ,
wherein the processor controls a position of the second display in the midair based on information regarding the position of the region from which the first display can be observed and the position of the object.
20. The controlling device according to claim 19 ,
wherein the processor moves the position of the second display in the midair in a direction approaching a display surface of the display device or in a direction away from the display surface of the display device based on the information regarding the position of the region from which the first display can be observed and the position of the object.
21. The controlling device according to claim 1 ,
wherein the processor controls a contrast of a part of the second display to increase to more than a contrast of a part of the first display.
22. The controlling device according to claim 1 ,
wherein the processor controls a transparency of a part of the second display to decrease to less than a transparency of a part of the first display.
23. The controlling device according to claim 1 ,
wherein the processor controls the first display when a location of the object is substantially the same as a location of the first display.
24. The controlling device according to claim 1 ,
wherein the processor controls the display device to display the second display in a state in which the first display is displayed.
25. A detecting device comprising:
a detector that detects information regarding a position of an object; and
the controlling device according to claim 10 .
