Summary
According to the World Health Organization (2012), there are currently 285 million blind and visually impaired people worldwide, 39 million of whom are considered legally blind and 246 million of whom have sufficiently low vision to be considered visually impaired [1]. Visual impairment has increased in prevalence over the past three decades, with 90% of visually impaired people living in developing countries [1]. As one participant, who has been blind since the age of seven, has stated, “independence in one’s daily activities, without requiring/requesting assistance from a sighted person, is of the highest priority” [3]. This emphasizes the need to build systems that help visually impaired and blind people become more independent
