Tactile chart on a flat surface uses three set of columns which two of the row in each column consists of materials with different tactile properties (vellum, fur, cardboard, plastic, wood, wax, sheepskin, wire mesh, etc. ) and below in the last row there are graphs showing tactile values on grid paper. The compositional grid examines the tactile values such as hardness/ softness, smoothness/roughness, dryness/wetness by means of systematically combined materials for example man-made and natural, raw and fabricated ones. | |||
