Emotional analysis of design products based on facial expression

Abstract

This paper presents the description of an analysis method for design products based on facial expressions. Using the Donald Norman’s emotional design levels classification, the paper presents an analysis model that can be used to gain information from the reactive level. It proposes the use of Facial Action Coding System (FACS) and automated techniques from Computer Vision and Affective Computing to improve the accuracy and efficiency of the system in controlled and non-controlled environments. It concludes with a description of the steps for the development of the method to be applied to products in the Brazilian market and initiating a discussion on cultural aspects of the concept of satisfaction applied to the use of design products.
