Systems and methods for braille reading using a fingerprint scanner and varying vibration frequencies are disclosed. A method includes: obtaining, by a computer device, data defining a braille cell; identifying, by the computer device, one of six predefined areas of a fingerprint based on the one of the six predefined areas being centered on a fingerprint sensor; determining, by the computer device, a state of a braille dot of the braille cell that corresponds to the one of the six predefined areas of the fingerprint; and generating, by the computer device, one of a first type of vibration and a second type of vibration based on the determined state of the braille dot.

A mechanism is provided for virtually rendering a portion of a three-dimensional (3D) object to a user via a tactile display. The mechanism receives a selection of the 3D object to be virtually rendered to a user. The mechanism identifies a subset of cells of a plurality of cells that form the tactile display required to virtually render a portion of the 3D object that will be virtually contacted by the tactile display. The mechanism selectively controls a fluid flow to the subset of cells that form the tactile display to render a sensation associated with the portion of the 3D object on skin of the user wearing the tactile display, wherein the fluid flow to each cell the subset of cells is provided via one or more electrostatic accelerator pumps.

A fiber optic scanner system for reading coded patterns is provided having a single optical fiber extending from the reading end of the scanner tip to a remote terminal. The remote terminal includes an optical signal generator for generating and driving light pulses along the single optical fiber to the reading end of the scanner member so as to illuminate a bar code and obtain reflected pulses therefrom which are carried to the remote terminal receiver and decoded.
