Beyond Rationality: Affect as a Function of User Interfaces
The emotional part of human nature is rarely explored in design projects that involve interaction with electronic devices. Designs are usually guided by technical efficiency and the astonishment that derives from the speed of information processing in digital media. Considering the contemporary context and the concept of ubiquitous computing, this article seeks to identify achievements and future directions for the implementation of affective functions in interaction design projects, revealing a wide range of possibilities for development in this area. To achieve these goals, this paper draws parallels between computer science, neuroscience and interaction design; discusses the definition of the term ’affect’ in Spinoza and Deleuze; and establishes categories to analyze a series of objects that are either affectively influenced by the user, that are designed to affectively influence the user, or that facilitate affective exchange between two or more users.
