FrogPad
FrogPad is a small chorded keyboard about the size of a numeric keypad that can be used with one hand. It was produced by Frogpad Inc. The keyboard is optimized by character frequency. 85% of average keystrokes in English text can be typed without chording, and chords are limited to 2 fingers (opposable thumb and one finger). As a result, the FrogPad has many more keys than a GKOS or Microwriter or Baudot keyboard but fewer than a conventional computer keyboard A computer keyboard is a peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches.

Chorded Keyboard
A keyset or chorded keyboard (also called a chorded keyset, ''chord keyboard'' or ''chording keyboard'') is a computer input device that allows the user to enter characters or commands formed by pressing several keys together, like playing a " chord" on a piano. The large number of combinations available from a small number of keys allows text or commands to be entered with one hand, leaving the other hand free. A secondary advantage is that it can be built into a device (such as a pocket-sized computer or a bicycle handlebar) that is too small to contain a normal-sized keyboard. A chorded keyboard minus the board, typically designed to be used while held in the hand, is called a keyer. Douglas Engelbart introduced the chorded keyset as a computer interface in 1968 at what is often called "The Mother of All Demos". Principles of operation Each key is mapped to a number and then can be mapped to a corresponding letter or command. By pressing two or more keys together the user ca ...

Numeric Keypad
A numeric keypad, number pad, numpad, or ten key, is the palm-sized, usually-17-key section of a standard computer keyboard, usually on the far right. It provides calculator-style efficiency for entering numbers. The idea of a 10-key number pad cluster was originally introduced by Tadao Kashio, the developer of Casio electronic calculators. The numpad's keys are digits to , (addition), (subtraction), (multiplication) and (division) symbols, (decimal point), , and keys.numeric keypad' at FOLDOC Laptop keyboards often do not have a numpad, but may provide numpad input by holding a modifier key (typically labelled ) and operating keys on the standard keyboard. Particularly large laptops (typically those with a 15.6 inch screen or larger) may have space for a real numpad, and many companies sell separate numpads which connect to the host laptop by a USB connection (many of these also add an additional spacebar off to the side of the zero where the thumb is locat ...

Frequency Of Letters
Letter frequency is the number of times letters of the alphabet appear on average in written language. Letter frequency analysis dates back to the Arab mathematician Al-Kindi (c. 801–873 AD), who formally developed the method to break ciphers. Letter frequency analysis gained importance in Europe with the development of movable type in 1450 AD, where one must estimate the amount of type required for each letterform. Linguists use letter frequency analysis as a rudimentary technique for language identification, where it is particularly effective as an indication of whether an unknown writing system is alphabetic, syllabic, or ideographic. The use of letter frequencies and frequency analysis plays a fundamental role in cryptograms and several word puzzle games, including Hangman, ''Scrabble'', ''Wordle'' and the television game show ''Wheel of Fortune''. One of the earliest descriptions in classical literature of applying the knowledge of English letter frequency to sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microwriter
The Microwriter is a hand-held portable word-processor with a chording keyboard. First demonstrated in 1978, it was invented by UK-based, US-born film director Cy Endfield and his partner Chris Rainey and was marketed in the early 1980s by Microwriter Ltd, of Mitcham, Surrey, UK. By using a mnemonic alphabet, it was claimed to allow note-taking of up to 8,000 characters at an input rate averaging 1.5 times that of handwriting. The Microwriter MW4 Although there was an earlier unit with an LED display, the MW4 with an LCD was the most common unit. The 23 cm × 12 cm × 5 cm (9" x 5" x 2") device comprises: * A six-button chording keyboard. * A single line LCD. * An 8 bit CDP1802 microprocessor. * Complete Word processing software in ROM. * 16 kilobytes of RAM. * Rechargeable Nickel-cadmium batteries - sufficient to run the device for 30 hours. * Various interfaces (see below). This device is capable of allowing the user to enter and edit several pag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baudot Code
The Baudot code is an early character encoding for telegraphy invented by Émile Baudot in the 1870s. It was the predecessor to the International Telegraph Alphabet No. 2 (ITA2), the most common teleprinter code in use until the advent of ASCII. Each character in the alphabet is represented by a series of five bits, sent over a communication channel such as a telegraph wire or a radio signal by asynchronous serial communication. The symbol rate measurement is known as baud, and is derived from the same name. History Baudot code (ITA1) In the below table, Columns I, II, III, IV, and V show the code; the Let. and Fig. columns show the letters and numbers for the Continental and UK versions; and the sort keys present the table in the order: alphabetical, Gray and UK Baudot developed his first multiplexed telegraph in 1872 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Keyboard
A computer keyboard is a peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input method for computers since the 1970s, supplemented by the computer mouse since the 1980s. Keyboard keys (buttons) typically have a set of characters engraved or printed on them, and each press of a key typically corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence. While most keys produce characters (letters, numbers or symbols), other keys (such as the escape key) can prompt the computer to execute system commands. In a modern computer, the interpretation of key presses is generally left to the software: the information sent to the computer, the scan code, tells it only whi ...

Satori Tech Solutions
is a Japanese Buddhist term for awakening, "comprehension; understanding". It is derived from the Japanese verb satoru. In the Zen Buddhist tradition, ''satori'' refers to a deep experience of ''kenshō'', "seeing into one's true nature". ''Ken'' means "seeing," ''shō'' means "nature" or "essence". ''Satori'' and ''kenshō'' are commonly translated as enlightenment, a word that is also used to translate bodhi, prajñā and Buddhahood. Definition ''Satori'' means the experience of awakening ("enlightenment") or apprehension of the true nature of reality. It is often considered an experience which cannot be expressed in words. While the term ''satori'' is derived from the Japanese verb "to know" (''satoru''), it is distinct from the philosophical concept of knowledge as it represents a transcendence of the distinction between one that knows and knowledge. D. T. Suzuki, a Japanese author of books and essays on Buddhism, Zen and Shin that were influential in the West, des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Keyboard Models
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links bil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
