Developing Emotion-Libras 2.0: An Instrument to Measure the Emotional Quality of Deaf Persons while Using Technology

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.
