The Proposal of Educational Smartphone Application for Kaleidoscope Experience

It has become natural that people use smartphones for various purposes. Even the child has a simple smartphone with convenience, however, is it really meaningful for children to use smartphones? It is often the case that they use smartphones for watching "YouTube" or "games". those activities are only limited inside the frame of the screen. To solve this, here I propose the kaleidoscope application that combines digital (smartphone) with analog (kaleidoscope), which differs from the conventional smartphone application in respect of the usage, and is helpful for the education of the children. A body of the kaleidoscopes to be looked into is an analog device, but there is the screen of the smartphone in the bottom, and patterns change mysteriously in response to the screen changes. It is the educational application by which the knowledge of the science can be learned from an experience of the kaleidoscope vision.
