Design tool based on Sensory Perception, Usability and Universal Design

Abstract

The knowledge of the functioning of the human sensory system, by architects and designers, can contribute significantly to the development of more interactive design concepts and architectural solutions. However, the systematic availability of this information is still an incipient practice in both architecture and design fields. In this context, the objective of this work is to link the user’s sensory perception, through its perceptual systems, to the usability and the universal design, which are two other concepts that consider human beings at the center of their actions. The aim is to establish a conceptual basis for the development of a design tool dedicated to the creative stages of Assistive Technology projects, inserted in the built environment. A bibliographical survey discusses how the human sensory system organizes itself to collect information about the environment and how this information can be used by architects and designers during the design process. Usability principles are also addressed to better understand how it is possible to develop user-friendly environments, products and services that are easy to use, efficient, and enjoyable. Finally, we identify the principles of universal design that seek to ensure the concepts of inclusion and accessibility. The results of this research indicate the possibility of relating and synthesizing the principles of usability and universal design studied. Studies showed that they present aspects in common and they complement each other. After reduction of variables, it is possible to proceed to the formal structuring of the tool and its systematic use. With such a tool, architects will have knowledge about how to get information from the environment, together with usability criteria that establish principles of good functioning of environments, products and systems (use) and universal principles (broad access and participation).
