The braille keyboard was designed to stop the development of Carpal Tunnel Syndrome,
Cumulative Trauma Disorders, Repetitive Motion Syndrome, Repetitive Strain Disorders and Repetitive Stress Injuries, and other injuries.
Unlike other braille keyboards, this braille keyboard remains on your lap while you type.
Your entire upper body and arms are relaxed as your wrists remain straight while you type.
Preliminary testing of the ergonomic 8 key chordic braille keyboard
prove it to be the best way to stop the development of muscular and skeletal injuries.
Back, shoulder, neck, arm, wrist and hand pain or discomfort is prevented using the braille keyboard.
The 8 key chordic data entry method can be learned and used in five to ten minutes on the new braille keyboard.
Learning curves of previously tested chordic typing methods have proven them to be faster to learn and
faster to use than the standard touch typing method.
The 8 key chordic braille keyboard data entry method is far
superior to any previous chordic data entry method and is easy to learn and fast to use.
The 8 key chordic braille keyboard data entry method can also be used as an alternative 8
dot braille arrangement for the blind and a new form of communication
''fingerbraille'' for the deaf-blind community.
Individuals who write or use the hunt and peck method of typing will be able to type faster in a very short
period of time (minutes to hours) using the 8 key chordic braille keyboard
data entry method.
The braille keyboard uses the split space bar keyboard as a chordic 8 key braille typewriter (a chordic stenographer keyboard).
All Latin based alphabet languages and all computer data found in the ASCII and Extended ASCII 8 bit binary computer code
are produced by typing combinations of 8 keys.
The ASCII and Extended ASCII 8 bit binary computer codes have been rearranged into a new copyrighted and patented
8 bit binary computer code that can be used as a method of typing,
an 8 dot Unified Braille Code for computer data and all Latin based alphabets or as a method of
finger braille / finger spelling form of communication
for the speech impaired and DeafBlind community.
Typing is still a requirement for entering data into a computer.
The smallest key that can be comfortably used on a standard keyboard is roughly 19mm across (3/4 inch).
Portable computers usually have keys smaller than the keys found on a standard computer keyboard.
A solution to the problem of a keyboard size is to abandon standard keyboard designs and use a chordic keyboard.
On standard keyboards, a data character is made by pressing either a single key or a key combined with the shift key or another key on the keyboard. A
chordic keyboard uses only one key for each finger.
Combinations of keys are pressed simultaneously to enter a data character or some other type of data,
similar to producing a chord (note) on a piano.
Pressing combinations of keys in this way is called ''chording''.
A chord keyboard has several advantages over standard keyboards.
Novice typists can type almost twice as fast on a chord keyboard within a couple of days of training.
The repetitive motions and finger accuracies required for touch typing are very complex.
Finger muscles and touch typing speeds decay quickly when not used,
and it can take a while for a typist to regain previous touch typing speed proficiencies.
Chordic typing speeds decay very slowly when not being used due to the mnemonic
(memory) relation between the chords and the characters.
It is easy to type the wrong key while touch typing on a standard keyboard because of the unnatural finger movements,
the large number of keys used and the illogically dispersed arrangement of the keys on the keyboard.
A chordic keyboard does not have this problem because each finger is assigned to only one key.
Only up an down movement is involved, making it is impossible to press the wrong key or miss the key.
Chord keyboards have the lowest error rates and the fastest learning curves compared to any other type of keyboard or keyboarding technology.
The biggest advantage to chord typing is that the typist never has to look at the keyboard while typing.
Most disabled individuals cannot use standard keyboards, but can achieve acceptable typing speeds on chord keyboards.
The chordic braille keyboard makes all existing keyboards and keyboarding technologies obsolete.
- Pressing any key on the braille keyboard produces the data labeled on the key face, just like a standard computer keyboard or typewriter.
- While typing or touch typing, the braille keyboard has an editing mode that is entered into by pressing the left and right space bars both down at the same time.
- The braille keyboard allows the typist to easily backspace and delete data or move the cursor to the left and to the right while in the editing mode or cursor movement mode.
- Pressing the 6 dot braille 'Hot Key' allows the braille keyboard to type Grade 1 braille.
- The editing mode available while touch typing on the braille keyboard also works while typing Grade 1 braille.
- Pressing the 8 dot braille 'Hot Key' allows the braille keyboard to type the Unified Braille Code.
- The chordic 8 key data entry method, typed on the braille keyboard, can also be used as the only Unified Braille Code arrangement for Latin alphabet languages.
- While in the 8 key chordic typing mode, the braille keyboard has the lowest error rates and the fastest learning curves.
- All computer keyboard data and every Latin based alphabet can be typed using only 8 keys on the braille keyboard.
- The braille keyboard does not have to sit on a desk or keyboard tray, it was designed to be used while positioned on the lap.
- 8 key chordic typing on the braille keyboard allows ergonomic positioning of the arms, wrists, hands and fingers.
- The braille keyboard is the only keyboard that prevents the development of Carpal Tunnel Syndrome, Cumulative Trauma Disorders, Repetitive Motion Syndrome, Repetitive Strain Disorders and Repetitive Stress Injuries.
- The Deaf-Blind community can communicate faster using the 8 key data entry method as a new finger spelling technique (finger braille).
- Multiple types of data entry modes increase the speed and ease of use of the braille keyboard.
- The braille keyboard is the only keyboard device that meets with all the requirements found in the Individuals with Disabilities Education Act and Section 504 and Section 508 of the Americans with Disabilities Act.
- The braille keyboard makes all existing keyboards and keyboarding technologies obsolete.
