This thesis deals with designing and implementing two systems that will help the blind people to perform their daily work. The first system is responsible for human vision, which contains four parts: microcontrollers, display tongue, PC, and a camera in order to perform the brain vision functions. The camera will take a photo in the front of blind person where the photo can be letters, numbers, or an object. The microcontroller will convert the image to electrical pulses and send them to the display tongue. The sensors of the tongue of the blind person send these pulses to the neural vision part of the brain, so that the pulses are converted to a vision image, and hence the blind person can recognize what is in front of him. The second system is a voice alert system which contains microcontroller, ultrasonic sensor, and headphone. The main function of this system is to help the blind person to recognize what is around him by different beeping voices based on the distance.
