Abstract— In present era smartphone market is growing rapidly. But the visually challenged persons are not able to access the general features of smartphone such as appointments, tasks, reading and writing SMS, checking - battery power status, current time and date, network status. A part from this they are unable to adding contacts, making calls and accessing music player. In this paper, Blind user inputs text command and receive speech- output as response. Buttons (in case of event handling in .NET compact framework) [2] for charactes and commands are placed on touch screen[2] of the Smartphone (Windows Mobile)[15][16] and Braille overlay[3][4] is placed on touch screen. When user touches any character or some commands, respective character or command will be read aloud as feedback so that user can be assured for correct input. For reading aloud text messages, Text to Speech sytem[5][11][6] is there which converts text into audible form. The text is read aloud by audio player. Related work done by some other researchers, is limited to audio access to smartphone[1]. There is no provision to input text using Braille.
