Interprinter has a two-way output function: under writing mode, the blind can input voice through the matching Bluetooth headset, after recognition and conversion, Braille can be printed by scrolling the ring; under reading mode, the real-time conversion can be realized by the scanning camera hole, the built-in Ai and the headset. Interprinter is usually worn on the right index finger with power switch at the top, function keys on the left and right side sunken to make the middle finger fit the ring body.
