Soap Bubble as a Display Screen
Scientists have developed the world’s thinnest screen from soap bubble. This screen can display images whether flat, textured or 3D. This screen has been developed by Yoichi Ochiai from the University of Tokyo.
Although the soap films vary in transparency and reflectance but the scientists have controlled these properties by using ultrasonic sound waves coming out of the speakers to change the surface. They skillfully controlled the texture of an image with the help of a single projector. They showed the video demonstration of different pictures and short videos.
In order to produce 3D effect, scientists combine several screens. A holographic projection has been shown by displaying alternate images on each other. As the film is made up of a mixture of colloids, which are difficult to break, so it is easy to nudge the screen and interact with it.
Alexis Oyama, a member of the team, said that this display could be useful to people such as artists and exhibitors to give an image a realistic feel such as the feeling of the Earth’s display in the air as the screen is transparent and this has been shown in the video demonstration. "Museums could display floating planets by using this technology," he says.
The system will be presented at Siggraph 2012, a conference on computer graphics and interactive techniques, in Los Angeles in August.
