An important issue in the capture of the real user experience while interacting with technology is the ability to assess emotional quality. There are several methods for emotional quality evaluation in the literature. However, when the target users are deaf participants, communication problems arise. A substantial part of the deaf community communicates in sign language. Because user experience researchers are seldom fluent in sign language, they require the assistance of an interpreter whenever users are deaf signers. Evaluation of emotional quality may lose accuracy because of the mediation of an interpreter; consequently, emotional quality evaluation requires a special instrument that can be used in an intuitive and independent way by researchers and their deaf subjects. The authors present the process of creation and improvement of Emotion-Libras, an instrument for assessing the emotional quality of people with hearing disabilities when interacting with technology.

Emotional Quality Evaluation Methods: Background

In this section, we depart from the definition of the word “emotion” and the expression “emotion quality” adopted in this paper. As stated by Scherer (2005, p. 696), “The number of scientific definitions [for the word emotion] proposed has grown to the point where counting seems quite hopeless (Kleinginna & Kleinginna already reviewed more than one hundred in 1981)”. Ekman (2003, p. 13), for example, states that “emotion is a process, a particular kind of automatic appraisal influenced by our evolutionary and personal past, in which we sense that something important to our welfare is occurring, and a set of physiological changes and emotional behaviors begins to deal with the situation”.

In this sense, adapting from Scherer’s definition (2005), we assume that emotion is the situation in which a person is affected by one or more feelings, either positive and/or negative, driven by a set of factors that influence actions and reactions, for example, past experiences, personal tastes, external factors, desires, and needs. Thus, considering this definition, emotional quality was defined as a value generated from the qualitative measure of a person's emotions.
