Touchscreen Mobile Phones Virtual Keyboarding for People with Visual Disabilities

Abstract: This paper presents the design and initial evaluation of a Braille virtual keyboard which allows text input on touchscreen devices such as smartphones and tablets. The virtual keyboard, called LêBraille, is a metaphor of the Braille writing system that uses audio and vibration feedbacks to promote accessibility for people with visual disabilities. We integrated this keyboard into two mobile applications and implemented an initial usability evaluation with nine people with visual disabilities. The evaluation co… Show more

“…Speech input methods like Siri raise privacy and security concerns. Braille-based techniques (e.g., EdgeBraille (Mattheiss et al 2014), Holibraille (Nicolau et al 2015), LêBraille (Façanha et al 2014), BrailleTouch (Southern et al 2012), and BrailleKey (Subash et al 2012)) are designed for visually impaired users. They are not suitable for those who do not use Braille and for people without visual impairments.…”

“…O GBraille Keyboard permite a inserção de todos esses símbolos com apenas três gestos na tela. Um projeto anterior foi desenvolvido um teclado visual baseado em Braille, o LêBraille [FAÇANHA et al 2014]. Entretanto, apesar de permitir a entrada de dados III Congresso Brasileiro de Informática na Educação (CBIE 2014) XXV Simpósio Brasileiro de Informática na Educação (SBIE 2014) _______________________________________________________________________ com essa metáfora, os tempos de escrita eram bastante impeditivos para seu uso como instrumento de aprendizagem ou prática do Braille.…”
