Semiotic ladder artifact to design an assistive technology product for people who are deaf

Brazilian Sign Language (Libras) is the native language of people who are Deaf or Hard of Hearing (D/HH) in Brazil and it does not replace the Brazilian-Portuguese written language. Considering this fact provided by law, in 2017, the High School National Exam (ENEM), an exam organized by governmental education sector for people to ingress in undergraduate programs, first offered the video-exam in Libras for D/HH candidates to access contents in Libras. The video-exam can be considered as an Assistive Technology product, since it may enable D/HH students' autonomy by displaying contents in their natural language. A framework for adoption of an Assistive Technology is under validation through a case study co-designed with stakeholders, in which this investigation is part of the process. In this paper we show requirements and main questions categorized in six levels of the Semiotic Ladder artifact and, from it, we define the group who are the most important stakeholders that have to participate in futures semio-participatory workshops.
