An attempt has been made to develop a method of introducing 1/f fluctuation characteristics into aesthetic objects. First, topographic features of various tea bowls are measured using laser metrology, and their wave patterns are analyzed by the FFT and characterized by using power spectrums. The quantification of an affective factor involved on the outer surface of the tea bowls shows that the handmade tea bowls have an inclination close to −1 on the spatial frequency-power spectrum diagram, which means that it has 1/f fluctuation characteristics. A mass-produced one, on the other hand, tends to have an inclination of near −2, which gives us a monotonous or dull impression. Next, the 1/f fluctuation property is applied to shape design, in which the surface of a tea bowl is created using the measured texture. Rapid prototyping technology is employed to substantiate the model, and it has been confirmed that the accuracy of duplicates is satisfactory. Finally, a mathematical model with 1/f fluctuation characteristics is illustrated to mimic a real handmade tea bowl by using the proposed method.
