Outline of Final Research Achievements |
This study was carried out in order to develop the astronomical observation system for the visually impaired person. This system consists of the lens with 16 mm focal length, and the 1 inch color CCD. Once the CCD captures the image of the night sky, then the stars are automatically detected in order to measure the brightness and color of each star. The brightness of the star is estimated by the amount of the pixel value of the CCD. On the other hand, the color of star is determined from the combination of the R (red), G (green), and B (blue) of the CCD image. These information are output as sound, which reflects the brightness and color of the star as the loudness and the frequency, respectively. Finally, this system demonstrates its usefulness in understanding of the diversity of the brightness and color of the stars and the geometrical position of the stars in the sky.

Academic Significance and Societal Importance of the Research Achievements |
現代社会において,教育のボーダーレス化・バリアフリー化は重要なキーワードである.しかしながら,視覚に障がいのある人々にとって,ほぼ100%を視覚情報として取得する「天体観測」には大きなハードルが存在する.本研究の意義は,天体(主に星)が発する光の明るさ・色を,音量・音階といった音声情報に変換することで,視覚に障がいのある人でも天文・宇宙に対する関心を高め,教育のバリアフリー化を促進する点にある.
