AUTOMATIC CHALLAN WRITTING MACHINE FOR BLIND PEOPLE

Electronics and Instrumentation Engineering

ABSTRACT This Project "Automatic challan writing machine for blind" is done to help the blind and making them to feel ease in filling the forms such as bank challans, withdraw format. which are sometimes look tedious even for the normal ones. Blind people are the ones who will always be given preference in services, yet some sort of input is required from them to make the service a best one. It would be tough for the blinds if these inputs are received in a written format. This project reduces the constraints for the blind in filling up a forms. This is achieved by of a set of modules to recognize the customer, interpret the details and making it an authenticated transaction with a feedback mechanism. Face recognition module to identify the customer, voice recognition module to get the details from the customer, printer to provide an acknowledgement to the customer for future use, voice feedback module to direct the customer and to make sure that the process is done in the right path, are some of the modules that are used in the project to provide an effective output. All these modules are controlled by a microcontroller. Thus the project will definitely be a golden egg to the blind by making them to fill the forms on their own without seeking help from others. The Feedback mechanism receive and verify the details in an interactive manner making the machine more user friendly. Thus all these features,advantages of the features also with their constraints are discussed in this paper.
