| Outline of Final Research Achievements |
We are developing a bubble-projection three-dimensional display (BP3DD) that will generate reflecting points in a liquid. This type of display is currently nonexistent. In this research, we examined bubble generation in water and ethanol to find the most suitable conditions for the BP3DD. Experimental results showed that when the water pressure was lower, the required energy to generate bubbles decreased linearly. The required energy should be lowest when the water pressure is similar to the water vapor pressure. When bubbles were generated in ethanol solution, the required energy was lower than that required in water. The minimum required energy to generate bubbles was approximately 0.5 J. We can conclude that the required energy to generate bubbles is dependent on the physical properties of the liquid and its pressure.

現状の立体映像は，３次元空間画像（３次元空間中に発光体／反射体を設置する方式）が実現できていない．人は物を立体的に見るために，両眼の輻輳角／両眼視差／焦点調節／運動視差の4つを主に用いている．全て矛盾なく鑑賞できる３次元空間画像の多くは，奥にある物体から発せられた光を，手前にある物体が遮らないため，奥が透けて見えるゴーストのような映像となる．本研究の結果，輻輳角／両眼視差／焦点調節／運動視差の全てを矛盾なく空中に実像として提示でき，全方位から多人数で観察でき，専用メガネが不要な3次元ディスプレイの実現可能性が示された．
