A self-contained data terminal or typewriter keyboard completely operable by a single human hand for the input of information into a computer or other electronic device. The keyboard comprises five sets of keys, each set aligned respectively with the thumb, index finger, middle finger, ring finger, and small finger of an extended hand. Complementary orientation and positioning of the sets are determined by whether the terminal is to be used by a right-handed or left-handed user. The control keys may be used to manipulate text or other information entered into the attached device and are operated by the thumb. The character keys consist primarily of letters of the alphabet, numbers, and punctuation sets and are positioned below the remaining four fingers. The terminal is operated in a single keystroke character input mode. Several data control keys can also be mounted to the terminal to perform additional text manipulation functions, similar to the control keys, or any other necessary commands. By using single keystroke input keys according to the present invention, data input is faster and easier than with conventional terminals because only one hand is necessary, and there are fewer and less complex character input commands to memorize. |

DETAILED DESCRIPTION The electronic data entry or typewriter terminal according to the present invention is completely operational by a single human hand and includes character keys which are separated into four different arrays, positioned and angled to align with the index, middle, ring, and small finger of an extended human hand.
Each array contains at most eight keys.
A fifth array is mounted to be accessible to the thumb of the same hand and contain those keys necessary to control the input and manipulation of data entered using the character keys.
The control keys perform tasks such as entering commands, controlling a cursor, inserting or deleting text, and shifting from lower to upper case characters.
A third set of keys, referred to as data control keys, can be mounted to be accessible to several fingers of the hand operating the terminal, and can be used to input similar character or control commands.
By requiring only one hand for operation, the apparatus provides the other hand with a degree of freedom not found in standard two-hand models.
The system of inputting data using character and control keys is also faster to learn, because the keys are organized into five distinct arrays.
The keyboard organization, by placing the keys in five arrays, provides a format that is not only easier to memorize, but also simpler for the user to comprehend.
