Reproduction of Tactile Paintings for Visual Impairments Utilized Three-Dimensional Modeling System and the Effect of Difference in the Painting Size on Tactile Perception

摘要

It is difficult for blind persons to appreciate painting. To facilitate the appreciation by tactile perception, the Francesco Cavazza Institute for blind in Italy is developing three-dimensional tactile painting for blind persons. We are developing a system which product tactile paintings utilized three-dimensional model making technology cooperation with Cavazza Institute. This method enables us to manufacture paintings of varied sizes. In this study, we examined the possibility of down-sizing products. We find blind persons to be useful means of materials which reaffirm the painting image.
