Mitsui Shipbuilding & Engineering etc. develop the technology that clearly projects the character and the picture onto the surface of the water.

The one of this technology of installing 50 devices that make the wave in surroundings of round water of the size of 1.6 meters in the diameter and 0.3 meters in depth so, controlling the vertical movement of the part where the wave of the per-device is caused based on the calculation, and making the shape of the picture and the character come to the surface of the water like being also in the photograph. It is said that the calculation type that is called "Bessel function" will be used for this control. It shows by piling up a small cylinder wave as a point like the line, and the figure etc. are described on the surface of the water.

Ability shortage still as it took about 15 minutes to input described of the straight line etc. difficult, and data though the technology that had looked like so far was being developed by this company. It is said that the straight line is able to have been able not only to be drawn beautifully by the technology developed this time but also to be going to shorten the data input time greatly at most for about 30 seconds.

It is at the moment that the character and the mark appear in the surface of the water because of the wave. It sweetens the pie to the water of the water tank, and however, the shadow attaches to the ruggedness by appropriating the lighting, and it is possible to confirm it to the surface of the water well with the unassisted eye. Moreover, it is said that it is possible to make various pictures and characters come continuously to the surface at intervals of three seconds. For instance, if the same picture is continuously displayed, it seems to display continuously, and if spelling English is made to be one by one displayed by one character, it is likely to be able to use it as a display of the word and the message. Moreover, production of drawing the picture from a local terminal, and projecting it on the surface of the water then and there disappeared in impossibility.

It is said that the device by this technology can be constructed from 12 million to about 14 million yen according to a former article.

For instance, the place that can be used is thought as an interior that the message and is high depending on the device of production such as lobbies at the exclusive hotel and plazas in Theme Park very much. Moreover, there might be an utility value according to the conception besides the entertainment field.
