Outline of Final Research Achievements

We focus on the characteristics of the hydrogen bubble method to develop the technical basis for a new and novel underwater two-dimensional image display system. We created an experimental apparatus that sweeps multiple electrodes submerged in water, and conducted experiments to generate hydrogen bubbles with electrodes of various shapes. We also developed software to obtain the timing of bubble generation. The structure of the electrodes was finally adopted, which we call the harp type. It was found that the appearance of the two-dimensional bubble image depended on the angle formed by the multiple electrodes. Although we were not able to obtain a highly accurate two-dimensional image, we predicted that various visual impressions could be obtained by devising the placement intervals of the electrodes.

Academic Significance and Societal Importance of the Research Achievements

本研究の独自性は、 ①気泡が水中に忽然と現れ次第に消失するという、視覚的な意外性を有する点と、②流れの多様な形相に情報を付加できる点である。これらの特徴は、一般のディスプレイ装置が「装置然」としてしまうのに対して、本研究が「脱装置」を指向できることを示唆している。これらの特徴を引き出しながら、技術基盤を構築していくことで、表現手法としての発展を目指す。
