Description

Keyboard for Braille character set

The utility model relates to the field of equipment, in particular to keyboards for typing characters using the Braille system.

The proposed keyboard can be used as a multi-functional computer keyboard for entering Braille code characters, disk operating system commands (DOS or Windows), as well as entering text editing commands. It can also be used as the governing body of typing machines, typewriters in Braille and others.

A known typewriter is Braille 1, which includes a keyboard consisting of clavs mounted on levers that have an optimal punch-to-shoulder ratio, and the symbol keys have a concave surface that repeats the shape of the phalanges of the fingertips, index, middle and nameless.

A disadvantage of the known device is the low speed of inputting information and increased fatigue due to the need to move the keys, which requires sufficiently large muscular efforts when a key is pressed, which leads to a decrease in productivity during the work of an operator (a person with visual impairments).

Known electronic keyboard for typing in Braille 2, selected as the closest analogue, containing a rectangular base, six character keys and the Space bar located at the bottom of the base.

The disadvantage of the closest analogue is the low productivity (especially when typing a large amount of information), due to increased fatigue of the operator’s hands due to the lack of support for the hands and their inconvenient location on the keyboard, this does not take into account the individual characteristics of the operator, low accuracy of character set by Braille due to the lack of recesses for fixing the fingers, as well as the limited functionality of the keyboard.

The purpose of the utility model is to increase the productivity and accuracy of typing using the Braille system by arranging a more ergonomic keyboard, constructing the keyboard in two parts and as a result of this spatially independent arrangement of the left and right parts of the keyboard, introducing supports for the hands and indentations for fixing the fingers, expanding functionality by introducing additional function keys and buttons into it.

This goal is achieved by the fact that the keyboard for typing in Braille has a base, six keys for typing and the Space key located at the bottom of the base. The key is that the keyboard is divided into two spatially separated parts: the left and right, the second key “Space and two buttons of the mode key“ Uppercase and “Numeric, the three keys for typing characters located on the left side of the keyboard and three on right, the first key “Space is located on the right side of the left side of the keyboard, the second key“ Space is on the left side of the right side of the keyboard, the button “Uppercase is located on the left side of the left side of the keyboard cheers, and the “Digital” button is on the right side surface of the right side of the keyboard, while the keys for typing characters are located in recesses corresponding to the location of the phalanges of the tips of the three central fingers of both hands on a plane, and supports are made in the lower area of the left and right parts of the base hands It is desirable that the recesses in which the Yu-Vichy keys are located, intended for character set, have a concave lateral surface for fixing the operator's hands. It is advisable that the keys and buttons have a convex surface. It is necessary that the supports for the hands have a concave surface. It is desirable that the concave surface of the supports for the hands correspond in shape to the area of the wrist - the base of the hands.

The proposed utility model is presented in the drawing.

The keyboard for typing characters in Braille contains a base consisting of two spatially independent parts: the left part 1 and the right part 2, supports for hands 3, six keys for typing characters in Braille 4, two keys “Space 5, mode indicator button "Uppercase 6, the button of the sign of the mode" Digital 7, the keys for typing characters are located in the recesses 8, with concave side surfaces 9.

All keys for typing in Braille 4 are located in the corresponding recesses 8 for fixing the position of the fingers. The recesses 8 have smooth rounded concave lateral surfaces. The keys, as shown in section in the drawing, have a convex surface.

Work on the keyboard as follows. The keyboard consists of two spatially independent parts, which allows you to choose a convenient location that takes into account the individual characteristics of the operator. Before working on the keyboard, the operator places the brushes of the right hand and left hand on the supports for the hands 3, designed to reduce the tension of the hands that occurs while working on the keyboard. The fingers of the right hand and left hand, except for the little fingers and large ones, are located in the recesses 8 above the keys for typing in Braille 4. The thumbs are located above the keys "Space 5. The little fingers of the right hand and left hand are located opposite the buttons of the sign of the mode" Uppercase and " Digital, 6 and 7 with OOTBCTCT Beifflo. When working on the keyboard, the orator places his hands by setting the hands of the hands on the supports for the hands 3, and, while typing the characters, activates the keys for typing in Braille 4. The alphanumeric character is entered as follows. Each character in the Braille code corresponds to the simultaneous pressing of a certain combination of keys for character set 4. The selected combination of activated keys for character set 4 is stored.

Fixing the input character in the form of a signal can be performed, for example, by pressing the last key pressed for the character set 4 of the combination keys corresponding to this character. Each character key in Braille 4 corresponds to one character element in the braille code. So for the character set “and in Braille - just activate one key for character set 4.

To set the character "b according to the Braille system - o - you need to activate two keys.

The operation "Space is carried out when one of the keys" Space 5 is activated by any of the thumbs, located on the side surfaces of the right and left parts of the keyboard.

To enter the operating modes of the keyboard “Lowercase or“ Uppercase and “Alphabetical or x Digital, use buttons 6 and 7, respectively, located on the side surface of the right and left parts of the keyboard on opposite sides of the Space bar. These buttons are switched by the little finger of the right or left hand. If button 6 is pressed (recessed), then capital letters are typed, otherwise - lowercase. To enter alphanumeric characters, use the button 7 to switch to the numeric or alphabetic mode of operation of the keyboard (digital register). Switching of button 7 is carried out with the little finger of the right hand, similar to how it was done when switching the operating modes of the keyboard "Lowercase or" Uppercase little finger of the other hand.

The position of the buttons 6 and 7 is depressed or pressed, that is, the button protrudes or is recessed flush, defines the keyboard operating modes “Lowercase or“ Uppercase, “Alphabetical or“ Digital. This allows the operator to control during the dialing the operating mode in which the keyboard is located and to correctly switch the keyboard operating modes.

Pressing the keys “Space on the right and (or) left parts of the keyboard in combination with one or more symbol keys can significantly increase the number of entered characters and commands and expand the functionality of the keyboard.

In order to enter text editing commands, for example, the “Slaughter” command, a simultaneous pressing of the Space bar of the right part of the keyboard and the first, counting from the left side, symbol key of the same part of the keyboard can be performed. In this case, the previously typed erroneous combination of symbol elements (erasing) is reset, and the keyboard is ready to dial a new symbol.

In a similar way, the input of the commands of the operating file system and others is performed. For example, the command to write the file “Save” can be performed by simultaneously pressing the space bar and the third character key on the left side of the keyboard. At the same time, depending on the contents of the file address selected (or typed) by the operator, the file can be printed, written to a hard or flexible disk, sent by e-mail, etc.

The proposed keyboard allows you to expand the functionality of the keyboard compared to the closest analogue. The spatially independent arrangement of the operator’s hands, facilitating the orientation of the wrists and fingers reduces the tension on the hands, in particular the hands, allows the operator to take any position in space and make movements when working on the proposed keyboard with the optimal effect, that is, the least voltage. . with the greatest accuracy, speed and with
