User Interface Evaluation of Design Alternatives of the Emotion-Libras—An Emotional Self-Report Instrument for Sign Language Users

Abstract

For researchers interested in analyzing participants’ self-reflection about their emotional experience during user studies, having an instrument designed for a specific target user can be seen to show empathy for providing socio-cultural elements that involved parties feel a connection with. In user studies, communication mediation between sign language users and non-signers may include a bias; therefore, direct communication between the involved parties is welcome to reduce this risk and expand sign language users’ autonomy. This paper presents the Emotion-Libras, a self-report instrument to collect emotional responses of sign language users after interacting with technology and report findings from a user study. We conducted a focus group with five sign language users to collect their perceptions regarding the three design alternatives of the instrument. As a result, participants selected the best-fitted design interface of the instrument and also found room for improvement in video quality, language choice, written labels and user control.
