The tablet had to cover specific ergonomic, functional and constructive features in terms of hardware and software principles. The braille comes out, through structured sectors with holes, according to the information that must appear and be read from the person. The standard Braille system was used and a tactile method for reading the information on the device. Each button, relief, and functional sector is specified as a symbol and logical arrangement. A separate accessory was designed in the form of a special braille keyboard that is conveniently locked through the USB Port. This is an accessory that can be used by all blind people, and it is possible to manage the whole tablet with it. The tablet was supposed to serve as a standard tablet reader by entering information into it via external USB devices. The principle was based on a far bigger idea – the tablet has access to the Internet.
