According to visually impaired people, in addition to guiding and safety support, assistance regarding the choice of appropriate colors and patterns for their clothes is required. Even though they cannot see their clothes, the visually impaired want to make a good impression upon others. This sort of social and psychological support is important in enabling the visually impaired to live independently and be able to socialize. A system that can recognize colors and patterns present on clothes is required. Therefore, we have previously developed an algorithm for such a system. In this study, a smartphone is employed to make the system easy to use. It is important to choose a light source for color recognition. In our experiments, we test a system with a cover containing a light inside and another system using environmental lighting that does not require a cover. Since the system with the cover provides a higher accuracy rate of color correction than one using environmental lighting, we implement it into a smartphone and perform evaluation experiments. The results of the experiments indicate that the accuracy rate is about 75% in color recognition and about 83% in pattern recognition, respectively.
