Specification

This invention relates to a device for facilitating the use of Braille bv the visually disabled.
The visually disabled will have to rely on Braille texts for acquiring information and these sources are limited in their content and variety.
This invention proposes a device which enables a vast area of knowledge available on websites, electronic media and the like to be brought to the visually disabled, dispensing with the need to depend on the standard Braille texts which are normally available.
The provides a direct interface between a computer and the user, by projecting text as Braille code.

The low cost of the device makes it affordable by a wide section of society. The light weight of the device and lower power consumption make it highly mobile.
The device, according to this invention, for facilitating the use of Braille text by the visually disabled, comprises an array of cells, each cell having six spring loaded pins to form a Braille character: a memory source, wherein the Braille text is stored; a microcontroller and an actuator, the microcontroller feeding the actuator with the text, line by line: a moving coinage for caning the actuator under and along the array, the said actuator, on a command from the microcontroller, causing predetermined pins of each cell to project just above the top surface the cell, corresponding to the Braille character in the text the actuator re-occupying the start position after completing its travel along the array, to continue the next/previous line in the array on receiving a fresh command. from the microcontroller.

This invention will now be described in greater detail by reference to the accompanying drawings which illustrate, by way of example, and not by way of limitation one of possible embodiments of the device proposed herein,
Fig. 1 illustrating an individual cell with pins Fig.2 illustrating the moving carriage with actuator Fig. 3 illustrating a block layout of the device.
Information available from the internet or otherwise is converted into Braille text format and stored in a memory source M, so much so that the said source will have a vast amount of knowledge in it for being accessed.
An array of cells C is provided, each cell having six spring loaded pins P to form a Braille character.
A microcontroller E and an actuator A are also provided, the microcontroller E feeding the actuator A with Braille text stored in the memory M, line by line of the text.

A moving carriage G driven by a motor T carries the actuator A under and along the array of cells, the said actuator, on a command from the microcontroller, causing predetermined pins of each cell to project just above the top surface the cell, corresponding to the Braille character in the text. Thus the actuator is made to actuate all the cells in a line with the Braille characters fed to its from the microcontroller, so much so that the user can ''read'' the line by placing his/her fingers on the projecting pins in the line.
The actuator, after completing actuation of the array , re-occupies the start position after completing its travel along the array, ready to continue the next/previous line of the text, in the same array of cells, on receiving a fresh command from the microcontroller, which is operated by the user.
Each pin is equipped with a mechanical latch which retains the actuated state of the pin without consuming powder.

The actuator below each cell triggers the correct combination of the pins to form the Braille character required. The process is repeated for all the cells. Thus the array of Braille cells represents a line of Braille text The array can be refreshed to represent any given line depending on the choice of the user. Just one actuator is required for the entire array of Braille cells.
It will be appreciated that various other embodiments of this invention are possible without departing from the scope and ambit of this invention.
