In the past, the appearance of products was developed through tracing mechanical components and specifications. Nowadays, the form of the product tends to embrace a concept found in the context of the user’s lifestyle.

The shapes of products are always reflected by the user’s needs and demands. Through analyzing product forms that designers can find from extracting quantitative visual data of product dimensions and proportions of components on product history or comparison, designers can use this as a great resource for understanding how these processes work. This information will provide students with visual literacy about the process of developing shapes reflecting environmental circumstance and the evolution of product shapes.
