There are 3.5 million people who are blind and 72 million people in the world. There are 7.5 million hard-of-hearing and dumb in Egypt and 75 million people around the world and this project involves around solving their difficulty in using computers, which is Computer Double Face.
There will be one office with a computer in one used by two people at the same time because it has two screens against each other and each screen has its own graphics card.
The person uses it through a microphone in which they say the thing to be searched for; in addition, the audio signals are sent to the Raspberry Pi to translate them and search for the desired, then the results appear through the speakers that are located on the sides of the screen, there is also a camera at the top of the screen that translates all sign languages into speech after that it is displayed on the screen by making a specific algorism.
The computer screen consists of a black frame. Also, between it is a transparent anti-heat glass plate, and on the sides are four semiconductor laser devices. When an order is made to open the screen, the laser beams start coming out in the form of the letter x until the screen is completed. The control unit is a raspberry pi model B, which is a very small control unit because it contains a Broadcom BCM2711 chip; that includes a 1.5GHz quad-core ARM A72 processor. The A72 is a powerful performance processor that was used in some Snapdragon 65x chipsets, and Bluetooth 5.0 support has been added, in addition to Wi-Fi networks.
The project aims to help people with special needs, who are deaf, dumb, blind, and young people, in addition, in terms of providing job opportunities for them in companies.
