Method and System for Previewing Apps in Braille using Electrovibration (Haptic) Feedback

A method is needed to use braille, a tactile writing system, to make mobile devices more accessible to blind and visually impaired users.

The solution is to add functionality to accessibility functions inherent in mobile devices. The blind user can "preview" the app under a finger through haptic feedback, which presents the braille dot pattern.

5. As the user's finger touches the text messaging icon, the system emits a braille pattern in sequence using haptic feedback

6. The user feels the active sequential dot patterns under the finger and starts to "read" the beginning of the text message

The user can touch this app and read in braille the n...
