This chapter explores the integration of Shitsukan into industrial engineering, highlighting its significance in product development, user experience, and manufacturing optimization. We review our collaborative research with industries and offer practical insights and methods for implementing Shitsukan-based design. At first, three major industrial applications are presented: halftone image quality enhancement for the printing industry, perceptual modeling in leather design, and star field reproduction in visual entertainment. Each case exemplifies how perceptual qualities influence industrial value and consumer satisfaction. We then expand on practical implementations, such as the quantification of onomatopoeia and the development of the Kansei Material Platform. These initiatives bridge academia and industry, enabling the creation of emotionally resonant products through systematic Shitsukan modeling. This chapter underscores the emerging role of perceptual engineering in fostering innovation and enhancing the value of industrial design.
