Today, 65 years ago, on November 16, 1960 (September 28, 1960), the Soviet Union developed a machine that could "speak" to help the blind. In mid-November 1960, the Soviet Sverdlovsk engineers built a machine that could "speak" for the blind to read ordinary newspapers. The working principle of this machine was to exchange literal light into electricity, then turn the current into sound, and the blind heard the sound could understand the content of the newspaper. When used, as long as the newspaper was placed in the mouth of the machine, an optical system with a very small motor would move along the text on the newspaper. The image of the letters into the optical system would form a variety of different sounds, after reinforcement, via the speaker. The machine could read, three and four hundred sounds per minute.
