In the contemporary world, the current of production of industrial goods and design of new products, are in close connection with marketing process.One of the main important factors for product success and it’s usefulness is the acceptable appearance of the object and a meaningful form. This research with it’s emphasis in linguistics, semiotics and product semantics, together with a specified field research has resulted to an understanding of effective factors in object perception. Moreover, the research has resulted into an effect of classification of objects in product semantics and creation of a semiotic table applied for industrial design. To summarize, the most important item in perception and identifying an object would be it’s form. Perception of product meaning would mean perceiving it’s utility and it’s function. Each object whose form expresses it’s function would be meaningful for the observer. Knowledge of elements and construction of a message in product language would create an effect in making a relation between form , meaning and it’s function. Tea-making instruments have been introduced as a case study for this research. Human need to the existence of object and it’s function defines the form of product and the compatibility of this function with the need of user would create a positive meaning and would improve the utility value of the product. To conclude a designer , with his reference to this research , can choose formal, lighting, sound ,graphical and other signs for his product with a better choice. To go more in details, every product can be analyzed from an aesthetic point of view and a work of art is consisted of a form and content which is inseparable and we can consider form as face( exterior) and content as meaning. Every object has two main sides, which is form and function, because every product has been made based on a specific need and a specific form must be given to the product to fulfill it’s form. The idea of every product would be an answer to the essential cause of the product, which has been named as Causa Essentialis or function by Aristotle. While we compare between form and meaning, form and content, form and function, we can see that content , meaning and function can be considered as the same. So we can say that a denotative meaning of a thing would be equal to function of a product. The main work of this research was also based on a comparative study between semiotics and functional view of product, which has it’s origin in German school of design, and it’s applications for industrial design has been considered in the paper. In categorizing different products, similarities can be traced which can register a mental picture of product in the mind of the observer. Any change in elements and constructs of the object would result to the change in mental picture of the object and can result in a change in perception and cognition of the product as well, and this can be viewed as an important matter of consideration for products which can have an effective part in human life.
