1. A spatial image display apparatus, comprising:
- a fog generator configured to generate fog that flows along a display plane in an aerial space;
a spatial image display device configured to emit visible light into the fog to form a spatial image in the display plane;
a sensor configured to generate a signal corresponding to a position of an object traversing the spatial image; and
circuitry configured to;
receive the signal, anddetermine the position of the object with respect to the display plane according to a spatial distance variation and a programmable timing tolerance, wherein the spatial distance variation and the programmable timing tolerance are set so that the circuitry determines the position of the object even if the object experiences a predetermined amount of shaking;
wherein a detection of the object traversing the display plane outside of the spatial image and opposite of a pseudo-physical button is considered a unique input command.

Abstract
An spatial image display apparatus and method for displaying a spatial image in an aerial space, sensing an object traversing the spatial image, calculating the position of the object'"'"'s effective centroid, and performing an input operation is disclosed. The spatial image display apparatus detects distances from the object'"'"'s surface thrust into the aerial display to more precisely determine the position on the spatial image at which the user intends to indicate.
