“…The following alternative user interface concept was developed to facilitate the adaptation of the complex modules of the virtual classroom to the two-dimensional tactile representation of the BrailleDis [12,14]. Using the implemented prototype, a blind user can perceive the content of the following modules: activity protocol, whiteboard, chat, participant's list and description module (cf.…”

Digital media offers multiple possibilities for inclusion of people with disabilities. Nevertheless, they pose barriers especially for blind learners as they hinder an active participation in synchronous learning settings. Virtual classrooms are a particularly good example for a complex media application as they combine various media types such as audio, video, graphical content and text which can only partially be perceived.Our work pursues the goal to facilitate an equal participation in virtual classrooms for blind users. In order to overcome these barriers, alternative user interface concepts for the display on a two-dimensional tactile Braille device have been conceived. Based on these concepts, the virtual classroom solution BigBlueButton was improved thereupon. A subsequent evaluation simulated a learning session with blind users in order to determine the acceptance and usability of the software adaptation. This user study shows that an active participation of blind learners in virtual classroom sessions can be achieved by using multimodal output devices and alternative concepts.

“…O método de observação direta tem como finalidade a realização da coleta de relatórios verbais de estudantes cegos (BABU & SINGH, 2013;FERATI et al, 2014;BAUMANN, 2012;KIRINIC et al, 2016;FRANCIS et al, 2013;KERKMANN & LEWANDOWSKI, 2012;BOSE & JURGENSEN, 2014;SCHOEBERLEIN & WANG, 2012;ENCELLE et al, 2011;KOHLMANN & LUCKE, 2015;LOUREIRO et al, 2015;MILNE et al, 2014;YESILADA et al, 2011;RUIZ et al, 2011;MARTÍNEZ & PLUKE, 2014). Assim, os participantes trabalham em uma única tarefa e simultaneamente são verbalizados os pensamentos dos participantes durante as interações (BABU & SINGH, 2013).…”

Com o avanço dos recursos tecnológicos e o acesso às informações por diferentes dispositivos, há uma lacuna nas investigações sobre a experiência do usuário (UX) em dispositivos móveis, mais especificamente, na experiência do usuário cego em relação aos atributos de usabilidade alinhados às características de acessibilidade. Assim, este trabalho propõe uma revisão sistemática da literatura, identificando os principais métodos da experiência do usuário cego aplicados nas interações por meio de dispositivos móveis. Dessa forma, foram identificados 805 artigos científicos, sendo selecionados 34 para a revisão sistemática da literatura, os quais endereçavam assuntos relacionados à usabilidade, à experiência do usuário cego e a dispositivos móveis. Por meio da extração dos resultados, identificou-se dezesseis diferentes métodos aplicados na experiência de usuários cegos. Destacam-se a aplicabilidade dos métodos apoiados por revisores especialistas, as técnicas de observações, estudos experimentais, validação e verificação de conformidade com as Diretrizes de Acessibilidade do Conteúdo na Web (WCAG).

“…There are multiple approaches to output the digital content of screens to BVIP, such as e.g. the outcome of the Tidia-Ae project [1], accessible classrooms [2,12]. Many of the barriers described by [11] are still existent, or only partially addressed, for instance in an accessible tabletop [13,15], where natural pointing gesture of the sighted users on artifacts on a small interactive table could be detected and the relevant artifact's content output to a Braille display.…”

Non-verbal communication (NVC) is challenging to people with disabilities. Depending on their impairment, they are either unable to perceive relational gestures within performed by sighted people, or they are unable to perform gestures by themselves in such an information space (in case of motoric impairments such as cerebral palsy). Also other 3D gestures such as sign language and other aspects of non-verbal communication could provide an accessibility problem during training, interaction, and communication. This summary paper gives an overview on new approaches, how computers could mitigate these various impairments. Based on this we discuss how the papers accepted for this session relate and contribute to this new and challenging domain.
