A shape design related to human sensitivity is difficult to evaluate. In this paper, we propose the evaluating method of a shape design by using 1/f fluctuation. The 1/f fluctuation is known as the fluctuation which gives people a comfortable feeling. Firstly, we investigated what kind of sensitivity information is included in the three dimensional shape of teabowls. In order to analyze the three dimentional shape, we use frequency analysis method. The measured samples are two handmade teabowls by the ceramist, and two machine-made teabowls. From the analysis results, the periodicity of shape and the human sensitivity have a certain correlation. Secondly, we apply the fluctuations to a reference shape of spiral flow line. The 1/f characterization is superimposed on the line. Finally, selective laser sintering method is applied to the fabrication of 1/f fluctuation objects that were designed by using 1/f fluctuation characterization.
