The effectiveness of graphic representation techniques used by industrial designers for the conceptual presentation of new products

Graphic techniques are very important means for designers. They can improve the conceptual presentation of new products before a client or a company, stimulating the communication of their potential, defending their benefits and making clear their commercial viability. To choose the most suitable graphic languages is essential so that the client can understand the proposal, allowing this way to establish a dialogue with the designer itself in order to improve the solution. Today the multiplication of graphic media has made it possible for the designers to have a wide range of ways to conduct and present their ideas, but it may happen that the graphic techniques chosen may not always be the most appropriate. This work aims to demonstrate the importance of graphic expression used as a tool for presenting ideas about new products, and evaluate the effectiveness of several graphic techniques in improving the client's understanding of the product, taking into account the conceptual clarity, the representation of the mode of use, the relationship with the user and the contextualization of the product in its habitat or use environment
