  • Modular refreshable braille display system
    Patent number: 11915607
    Abstract: This specification generally discloses an apparatus, system and method for refreshable braille display. The apparatus can include a first base having a contact surface and a plurality of cavities. The contact surface can be configured to receive fingertips. The plurality of cavities can be recessed from the contact surface. A plurality of pins can be housed within the plurality of cavities and configured to move in the plurality of cavities to selectively extend from the contact surface of the first base. A plurality of solenoids can be configured to at least partially operably connect to the plurality of pins. A controller can be configured to selectively provide a first electric current to the plurality of solenoids to generate first magnetic fields through the plurality of solenoids. The first magnetic fields can be configured to selectively move the plurality of pins to extend from the contact surface of the first base.
