Researchers at EPFL have developed a tablet to help people with a visual impairment find their way around unfamiliar places. The device very quickly forms shapes and relief maps that users can then explore with their fingers, using their sense of touch. The tablet could also be used to help visually impaired schoolchildren learn subjects such as geometry or mathematics. Navigating in an unfamiliar setting is a major challenge for people with a visual impairment. To make it easier for them to find their way, EPFL researchers have developed a lightweight and reconfigurable touchscreen tablet capable of generating shapes and maps. Users can then 'read' the graphic data on the screen with their fingers. The research is part of the European project Blindpad.
