Abstract
Ceramic tiles are products which aesthetic appearance plays a decisive role of success. In this paper we present an experimental method to evaluate the influence of luminance and contrast in the perception of spaces with ceramic wall tiles and floorings. We have employed three specific models: wood, marble and mosaic. These designs, widely used nowadays, are based on repetitive decorating modules and allow as to research interaction effects. Experiments are based on the presentation of digitally processed images of these models, aiming at quantifying the correlation between limit values of luminance and contrast and the perceptual effects. Fixing this relation we can modify different manufacturing parameters to assure the final product acceptation
