Das Keyboard
Das Keyboard is a series of computer keyboards sold by Metadot Corporation, a software company located in Austin, Texas. Some models feature blank keycaps, made with the purpose to help improve touch typing skills. The current iterations employ mechanical keyswitches manufactured by either Cherry or Greetech. It is worth to note that "the keyboard" in German is "die Tastatur", not "das Tastatur". Das Keyboard products There have been multiple generations of Das Keyboard: The first iteration, released in 2005, did not feature mechanical key switches, but in addition to the blank keycaps, it featured a Model-M-inspired design, and keys with individual weights that require a different amount of force to press. The second iteration in 2006 introduced mechanical key switches using Cherry MX Blue switches. The third iteration in 2008 was the first to be offered in both ''Ultimate'' (unlabeled) and ''Professional'' (labeled) versions. This USB-only keyboard also offered six-key ...

Rollover (key)
Key rollover is the ability of a computer keyboard to correctly handle several simultaneous keystrokes. A keyboard with ''n''-key rollover (NKRO) can correctly detect input from each key on the keyboard at the same time, regardless of how many other keys are also being pressed. Keyboards that lack full rollover will register an incorrect keystroke when certain combinations of keys are pressed simultaneously. Rollover has applications for stenotype, electronic music keyboards, gaming, and touch-typing generally. Keyboard usage During normal typing on a conventional computer keyboard, only one key is usually pressed at any given time, then released before the next key is pressed. However, this is not always the case. When using modifier keys such as Shift or Control, the user intentionally holds the modifier key(s) while pressing and releasing another key. * Rapid typists may also sometimes inadvertently press a key before releasing the previous one. Certain unusual forms of keyboa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Touch Typing
Touch typing (also called blind typing, or touch keyboarding) is a style of typing. Although the phrase refers to typing without using the sense of sight to find the keys—specifically, a touch typist will know their location on the keyboard through muscle memory—the term is often used to refer to a specific form of touch typing that involves placing the eight fingers in a horizontal row along the middle of the keyboard (the ''home row'') and having them reach for specific other keys. (Under this usage, typists who do not look at the keyboard but do not use home row either are referred to as hybrid typists.) Both two-handed touch typing and one-handed touch typing are possible. Frank Edward McGurrin, a court stenographer from Salt Lake City, Utah who taught typing classes, reportedly invented home row touch typing in 1888. On a standard QWERTY keyboard for English speakers the home row keys are: "ASDF" for the left hand and "JKL;" for the right hand. Most modern computer keyboa ...

Optimus Maximus Keyboard
The Optimus Maximus keyboard, previously just "Optimus keyboard", is a keyboard developed by the Art. Lebedev Studio, a Russian design studio headed by Artemy Lebedev. Each of its keys is a display which can dynamically change to adapt to the keyboard layout in use or to show the function of the key. It was launched initially in 2007 and is no longer available to new orders. Overview The design featured on the studio's website received attention on the web when it was featured on Slashdot on July 14, 2005, and afterwards for a few weeks on other technology websites. The original release date was "end of 2006", however production issues caused the Optimus mini three to be developed first, with the full keyboard delayed until the end of 2007. The keyboard was number 10 in the ''Wired Magazine'' 2006 Vaporware Awards and number 4 on the list in 2007 due to its numerous delays and feature reductions. The Optimus allows for greater user interaction, by dynamically displaying the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Happy Hacking Keyboard
The Happy Hacking Keyboard is a small computer keyboard produced by PFU Limited of Japan, codeveloped with Japanese computer scientist and pioneer Eiiti Wada. Its reduction of keys from the common 104-key layout down to 60 keys in the professional series is the basis for its smaller size while retaining full key size. It returns the control key to its original position as on the early 84-key IBM Personal Computer/AT and XT layouts. The current models in production are the Happy Hacking Keyboard Professional Classic, Professional Hybrid (wired/wireless dual connectivity), and Professional Hybrid Type-S (silenced variant of Hybrid) all in either dark or light colorways, and either blank or printed keycaps. Professional Hybrid models are also available in Japanese layout. History Beginnings Frustrated that each new computer system came with a new keyboard layout that became increasingly complex, Wada sought to create his own keyboard that he could continue to use with variou ...

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. Replacing early punched cards and paper tape technology .... History The founder and CEO of the company was Linda Marroquin. She left the company in 2008. The original FrogPads on the market at this time were intended to be used with mobile phones and supported only Bluetooth. Two attempts to relaunch the Frogpad had been ...

Unicomp
Unicomp is a manufacturer of computer keyboards and keyboard accessories, based in Lexington, Kentucky, United States. History In 1996, Lexmark International was prepared to shut their Lexington keyboard factory where they produced Model M buckling-spring keyboards. IBM, their principal customer and the Model M's original designer and patent holder, had decided to remove the Model M from its product line in favor of cost-saving rubber-dome keyboards. Rather than seeing its production come to an end, a group of former Lexmark and IBM employees purchased the license, tooling and design rights for buckling-spring technology, and, in April 1996, reestablished the business as Unicomp. Since 1996, the tooling and molds that Unicomp had inherited from Lexmark began to wear out, leading to a gradual decline in build quality and finish. However, in 2020 Unicomp replaced its tooling leading to quality improvements. The company also began shipping new designs at this time. Products Uni ...

Device Driver
In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used. A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device (drives it). Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface. Purpose The main purpose of device drivers is to provide abstraction by acting as a translator be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Source
Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code, design documents, or content of the product. The open-source model is a decentralized software development model that encourages open collaboration. A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public. The open-source movement in software began as a response to the limitations of proprietary code. The model is used for projects such as in open-source appropriate technology, and open-source drug discovery. Open source promotes universal access via an open-source or free license to a product's design or blueprint, and universal redistribution of that design or blueprint. Before the phrase ''open source'' became widely adopted, developers and producers have used a variety of other terms. ''Open source'' gained ...

Model M Keyboard
Model M designates a group of computer keyboards designed and manufactured by IBM starting in 1985, and later by Lexmark International, Maxi Switch, and Unicomp. The keyboard's many variations have their own distinct characteristics, with the vast majority having a buckling-spring key design and swappable keycaps. Model M keyboards have been praised by computer enthusiasts and frequent typists due to their durability and consistency, and the tactile and auditory feedback they provide. The popularity of the IBM PC and its successors made the Model M's design tremendously influential. Almost all later general-purpose computer keyboards mimicked its key layout and other aspects of its ergonomics. The layout was standardized by ISO in 1994 and ANSI in 1998, with minor additions—most notably the Windows key and Menu key. The Model M is regarded as a timeless and durable piece of hardware. Although the computers and computer peripherals produced concurrently with them are con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
