We present a new mobile text-entry method that relies on alphabet navigation and dismisses memorizing, offering visually impaired individuals an easy writing mechanism. Current mobile text-entry interfaces are not suitable for blind users and special braille devices are too heavy, large and cumbersome to be used in a mobile context. With the enormous growth of mobile communications and applications it was urgent to offer visually impaired individuals the ability to operate this kind of devices. Evaluation studies were carried and validated the navigation method as a new mobile text-entry interface for the target population.
