Abstract
BrailleOne is a mobile application designed to provide blind and visually-impaired Braille readers with an accessible keyboard for manual text input on their Android smartphones or tablets. Its purpose is to make use of adolescents and young adults’ excitement for technology in order to facilitate Braille learning and daily practice. The results of a pilot evaluation study suggest that BrailleOne could contribute to the overcoming of accessibility barriers in the field of text entry.
Highlights
Braille is a tactile reading and writing code used by individuals with blindness or other forms of visual impairment
After developing BrailleOne, we carried out a pilot usability test
All four interviewees agreed that an accessible Braille keyboard would be of value for blind and visually-impaired individuals who wish to use an Android smartphone or tablet
Summary
Braille is a tactile reading and writing code used by individuals with blindness or other forms of visual impairment. In Grade I Braille, most written characters can be represented by a “cell”. Cells consist of 6 dots arranged in two columns of three dots each. Different combinations of 1–5 dots in a cell are used to represent letters and other symbols. The proportion of visually-impaired individuals who are proficient in Braille is gradually decreasing, even though blind or visually-impaired Braille readers are more likely to engage in higher education, to be employed and to enjoy a better quality of life [1, 2]. One possible explanation is that digital techniques, such as screen readers, are becoming increasingly popular
