Abstract. Touch and the discriminative general senses encompass a number of sensory modalities. Touch by itself refers to crude (also called light) and movement sensation, which yields little information apart from the fact of contact with an object.
Tactile means touch. Tactile texture is the actual (3D) feel of a surface. This is of paramount importance to three-dimensional design but of only moderate interest in two-dimensional design. The actual surface texture needs to either be felt, or seen with light raking across its surface to make the texture visible.
