Virtual simulation and embedded module of mobile phone using modified Braille display

Mobile phone embedded with recent technologies play a major role in day to day life of everyone in the world and thus shrinking the world with the well connected network. Yet there are people who have not been able to relish and benefit from the advanced technology. One among those deprived are the visually challenged people. Therefore an attempt has been made to develop a simple user friendly and cost effective mobile phone by which the visually challenged can save the numbers, make calls, receive calls and the most important is that they can easily feel the display. Initially, the function of the mobile phone incorporated with Braille display has been virtually simulated using LabVIEW. The simulation has been performed by creating the graphical nodes of mobile phone set up in LabVIEW front panel. The simulated mobile phone incorporated with Braille display model has been implemented using PIC16F877A microcontroller and SIM-300 GSM module. The embedded hardware module of mobile phone for the visually challenged people has been validated for ease of its operation with all possible features. The details of simulation of mobile phone using LabVIEW, and embedded module have been furnished in this paper.
