Development of Selection System of Comfort Pillow

Abstract

The purpose of this study was to develop the selection system of comfort pillow according to subject's head shape. 3-D scanner was used to measure the head shape of Korean. The head shapes were classified into 4 types. When a pillow was pressed by head, the height of pillow was estimated by the relationship of the pillow stiffness and pressure distribution of head and neck. The height, shape, and stiffness of pillow were investigated and their relations were found. The selection rule of comfort pillow was determined by the relationship among the head shape of subject, the height, shape, and stiffness of pillow. There was a significant correlation between the satisfaction and selected pillow. The developed final system consisted of a measurement stand, pressure sensor matrix, 3D scanner, analysis S/W and PC.
