Keynoa Braille Fingers Mapping

Braille keyboards contain single keys that represent each of the dots in a Braille cell. For 6-dots Braille there are 6 keys corresponding to each of the 6 dots:

  • dot 1: key of index finger from first hand
  • dot 2: key of major finger from first hand,
  • dot 3: key of ring finger from first hand,
  • dot 4: key of index finger from second hand
  • dot 5: key of major finger from second hand, and
  • dot 6: key of ring finger from second hand.

To type a character in Braille the user presses a combination of keys from these 6 keys according to the Braille method of the particular language used.

Keynoa Braille Fingers Mapping associates to characters the same finger combinations as those of the keys described above. Therefore people knowing the Braille do not need to learn a new finger mapping to be able read and write with Keynoa Braille using Keynoa Rings.

Similarly to Keynoa Method users read a character by receiving vibrations on the corresponding fingers and also write that character by producing taps with the same fingers. 

Keynoa Braille method can be executed by two hands simultaneously or by one hand only executing successively with one hand what the left hand does followed by what the right hand does. In both cases, the left hand index, major and ring fingers represent, in Braille cell, the left 3 dots line and the right hand index, major and ring fingers represent the right 3 dots line.

If a line of dots is empty, then the thumb of the corresponding hand (left or right) that is used to indicate it.

Keynoa Braille Fingers Mapping - Using two hands

Keynoa Braille method can be used by two hands simultaneously similarly to using a Braille keyboard with two hands.

To write or read Braille latin alphabet with Keynoa Braille method with two hands, are used simultaneously:

for letter “a”, the left index and the right thumb,
for letter “b”, the left index, the left major, and the right thumb,
for letter “c”, the left index and the right,
for letter “d”, the left index, the right index and the right major,  etc.

(Following is a graphics image illustrating 30 pictograms. Each pictogram shows the 2 hands (left and right) where the fingers associated to each of the 26 Braille latin letters plus 4 frequently used symbols are marked with red dots.)

Keynoa Braille Fingers Mapping - Using one hand

Keynoa Braille method can be used by one hand only. This can be done by executing successively with one hand:

  • what the left hand does with the index, major and ring fingers representing the left line of dots in the Braille cell, followed by
  • what the right hand does with the index, major and ring fingers representing the right line of dots in the Braille cell. 

In other words, to write or read Braille latin alphabet with Keynoa Braille method: 

  • use the index finger followed by the thumb for letter “a” 
  • use simultaneously the index and the major finger followed by the thumb for “b” 
  • use the index finger followed by the index for “c”,
  • use the index finger then simultaneously the index and the major finger for “d”, etc.

(Following is a graphics image illustrating 30 pictograms. Each pictogram shows the 2 hands (first and second) where the fingers associated to each of the 26 Braille latin letters plus 4 frequently used symbols are marked with red dots.)

Keynoa Braille on tactile screen

Keynoa offers the possibility to read Braille text on the tactile screen of a smartphone or tablet by sensing the Braille characters dots on the device screen. When touching a Braille cell dot on the screen, the users feel coded vibrations on the fingers (or on the device), allowing them to read the associated Braille character.

The user selects a digital text on the mobile device, Keynoa App converts it to Braille characters text and displays it on the tactile screen of the mobile device. The user scans on the screen the Braille characters of the text by touching the 6 dots, present and the absent, of the Braille cells. 

 

Reading Braille on tactile screen using Keynoa Rings

Keynoa App displays the Braille text characters on the tactile screen of the mobile device. The user wearing Keynoa Rings device scans with one finger the text Braille characters displayed on the screen. Touching the six present and absent dots of each Braille cell, the user feel vibrations produced on the fingers by Keynoa Rings. These vibrations are are as follows:  

  • when touching a present dot, the index finger ring vibrates as long as the touching finger is on the dot.
  • when touching an absent dot, the major finger ring vibrates as long as the touching finger is on the dot.

(Following is a photo image showing a hand wearing Keynoa Rings and touching the screen of a tablet on which Keynoa App has displayed a text in Braille characters, the dots are black and the screen is white. In the middle of the screen there is a watermark image showing Keynoa Logo and the inscription “Keynoa Braille”)

Reading Braille on tactile screen with bare fingers

Keynoa App displays the Braille text characters on the tactile screen of the mobile device. The user with bare fingers (not necessarily wearing Keynoa Rings) scans with one finger the text Braille characters displayed on the screen. Touching the six present and absent dots of each Braille cell, the user feel vibrations of the mobile device. These vibrations are are as follows:  

  • when touching a present dot, the mobile device produces a long vibration.
  • when touching an absent dot, the mobile device produces a short vibration.

(Following is a photo image showing a bare hand touching the screen of a tablet on which Keynoa App has displayed a text in Braille characters, the dots are black and the screen is white. In the middle of the screen there is a watermark image showing Keynoa Logo and the inscription “Keynoa Braille”)
