A calculator for blind people typically employs audio output and tactile interfaces to convey information. It may have a keypad with raised buttons or Braille labels, allowing users to input numbers and commands through touch. The calculator then speaks the input and results aloud using text-to-speech technology, enabling visually impaired users to perform calculations independently. Some models may also feature additional accessibility tools, such as voice recognition for hands-free operation.
