Abstract

Commonly, and since its inception, the methodology of Industrial Design has considered the "use" of goods as a unique and timeless dimension when seeking to define the characteristics of products, this means that the requirements, features and functions of the products (tangible or intangible) raised in the design process, focus on the main person-object interactions, omitting secondary moments of interaction, such as maintenance, installation, removal, etc.. This work proposes a way to address the interactions between users and objects and provides a theoretical proposal for a classification based on "situations and events of interactions" that are inserted and repeated throughout the life of objects, and so possessing both such importance to the user as the same primary function, and thereby becomes a key to control the definition of the attributes and functions of all kinds in the products.
