It’s not always easy for the visually impaired to use mobile phones, but a designer has come up with a concept phone that might be able to solve the problem, dubbed the Tactile. The Tactile uses digital texture to allow the visually impaired to access a variety of features that are offered by modern multi-touch phones. This is achieved by using an array of conductive pins under the multi-touch display, sending digital information as pulses of electricity to the user’s fingertips to simulate texture. Sounds pretty fancy, but it’ll be a shame if it doesn’t become a reality- the Tactile would probably be really useful to folks who are visually impaired.
