Scientific learning material for teaching the principle of stereopsis to children is developed. Two wireless CCD cameras are equipped on the radio-controlled model car. Two images are taken by using these cameras. One is converted into red and the other is converted into cyan. These images are superimposed in real time by using the development program. This superimposed image can be viewed stereoscopically by wearing glassed composed of red and cyan film. In this learning material, children experience stereopsis by controlling the radio-controlled model car. 1. Introduction The using of the 3-D image as a scientific learning material for teaching has been improved in recent years such as in astronomy subject [1], and medical education [2]. The aim of using the 3-D image as a scientific learning material is for enhance the interest in science and made science easier to learn. It’s already proven that the teaching approach for science with science activities on student with an appropriate learning material give positive value to their comprehensive understanding of science [3-4]. Therefore, every year Gunma university has planned a scientific school for children. This activity is designed as contribute Gunma University to the local community. Science school was conducted in Takashimaya department store. A topic of science school is understanding stereopsis to children. One of the ways to achieve stereopsis is the stereogram. Two images shifted a little in angle are taken. Two images are viewed as a superimposing image. There are two methods of the stereogram, i.e. the parallel method and the intersection method. Figure 1 shows these two methods for stereopsis. The parallel method is used to view the images whose interval is smaller than that of human’s both eyes. On the contrary, the intersection method is used to view the images whose interval larger than of human’s both eyes. An anaglyph image is made as follows: 1) The colors of two images are changed to red and cyan. 2) The color of image A is changed to cyan, while that of image B is changed to red. 3) Two images are viewed by wearing glasses composed of red and cyan film. Figure 2 shows a photograph of the glasses composed of red and cyan film. The red image is viewed through a red film. The cyan image is viewed through a cyan film. Two images are easily superimposed as one image. This image is easily viewed stereoscopically. A scientific learning material is developed for the scientific school that is a radio-controlled model car equipped with two wireless CCD cameras, a course to run the radio-controlled model car, two programs to take images and to process images. The children will learn a stereopsis using a learning material with an enjoyable activity that is playing the radio-controlled model car. The stereoscopic animation is developed and the children can experience and learn stereopsis using the radio-controlled model car equipped two wireless CCD cameras.
