Much of our knowledge of what is around us depends on touch as well as sight. Our fingers react to rough and smooth surfaces, hard and soft, just as our eyes respond to form and colour. It is accepted that all cutaneous (skin) experiences such as itch, burn, stickiness, vibration, wetness and dryness, roughness and smoothness are due to simultaneous arousal of two or more of the primary skin senses. Touch is one of them.

We are mostly dealing with the visual sense and the visual imagery of the products, which gets quite emphasised in the "design world". But what kind of ‘product-images’ are formed in our minds due to our tactile sense is quite unknown. And the present project is an attempt to visualise and represent the ‘Tactile Image’ of a product. Such tactile images can open up new formal possibilities for designers. The sensation of touch usually results from the mechanical distortion of various types of sensory receptors in the skin. There are more touch receptors on the tongue and fingerprints than in other body areas. With this as background , I have chosen one of the personal products—a tooth brush—and attempted to represent its tactile image as best as I could. The reason for choosing a "tooth brush" is that it comes into contact with the tongue and fingertips, where more touch receptors are situated.
