Final answer:
The tactile sensation experienced when touching an object is known as actual texture in art, which is the real surface feel, unlike implied texture which is purely a visual illusion.
Step-by-step explanation:
When we touch an object, we experience a tactile sensation that artists refer to as actual texture. Actual texture is the real feeling of a surface, which might refer to the roughness or smoothness of objects and art media. On the other hand, implied texture is the illusion of texture we perceive with our eyes in a two-dimensional work of art, where the texture appears to have certain properties but isn't physically felt. Somatosensation, which is also known as the sense of touch, involves a variety of sensory modalities such as pressure, vibration, light touch, and temperature, and it is through these receptors spread throughout the body that we experience the sensation of texture.
