A keyset or chorded 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 that is too small to contain a normal-sized keyboard.
Typing is the process of writing or inputting text by pressing keys on a typewriter, computer keyboard, mobile phone or calculator. It can be distinguished from other means of text input, such as handwriting and speech recognition. Text can be in the form of letters, numbers and other symbols. The world's first typist was Lillian Sholes from Wisconsin in the US, the daughter of Christopher Sholes, who invented the first practical typewriter.
Autocomplete, or word completion, is a feature in which an application predicts the rest of a word a user is typing. In Android and iOS smartphones, this is called predictive text. In graphical user interfaces, users can typically press the tab key to accept a suggestion or the down arrow key to accept one of several.
Predictive text is an input technology used where one key or button represents many letters, such as on the numeric keypads of mobile phones and in accessibility technologies. Each key press results in a prediction rather than repeatedly sequencing through the same group of "letters" it represents, in the same, invariable order. Predictive text could allow for an entire word to be input by single keypress. Predictive text makes efficient use of fewer device keys to input writing into a text message, an e-mail, an address book, a calendar, and the like.
Japanese input methods are used to input Japanese characters on a computer.
T9 is a predictive text technology for mobile phones, originally developed by Tegic Communications, now part of Nuance Communications. T9 stands for Text on 9 keys.
A virtual keyboard is a software component that allows the input of characters without the need for physical keys. The interaction with the virtual keyboard happens mostly via a touchscreen interface, but can also take place in a different form in virtual or augmented reality.
LetterWise and WordWise were predictive text entry systems developed by Eatoni Ergonomics (Eatoni) for handheld devices with ambiguous keyboards / keypads, typically non-smart traditional cellphones and portable devices with keypads. All patents covering those systems have expired. LetterWise used a prefix based predictive disambiguation method and can be demonstrated to have some advantages over the non-predictive Multi-tap technique that was in widespread use at the time that system was developed. WordWise was not a dictionary-based predictive system, but rather an extension of the LetterWise system to predict whole words from their linguistic components. It was designed to compete with dictionary-based predictive systems such as T9 and iTap which were commonly used with mobile phones with 12-key telephone keypads.
The BlackBerry Charm is a discontinued smartphone made by BlackBerry Limited, then known as Research In Motion. The Charm was equipped with SureType technology, which used predictive type to allow for normal QWERTY-style typing using only 20 keys. It featured a 240x260 pixel display, polyphonic ringtones, quad-band GSM radio, and Bluetooth. The original 7100t (T-Mobile) was released in 2004, with the 7100r (Rogers), 7100v (Vodaphone), 7100g, 7100x (O2), and 7100i being released later.
The BlackBerry Pearl was a series of smartphones developed by Research In Motion, and was the first BlackBerry device with a camera and media player. It was originally released on September 12, 2006. T-Mobile was the first US carrier to release the phone as a carrier device. The last BlackBerry Pearl released was the 9100 series on May 13, 2010. After this model was cleared out, RIM discontinued the Pearl series.
A text entry interface or text entry device is an interface that is used to enter text information in an electronic device. A commonly used device is a mechanical computer keyboard. Most laptop computers have an integrated mechanical keyboard, and desktop computers are usually operated primarily using a keyboard and mouse. Devices such as smartphones and tablets mean that interfaces such as virtual keyboards and voice recognition are becoming more popular as text entry systems.
Released during Q3 2007 for T-Mobile in the US, the Samsung Blast (SGH-T729) slider features a double-tap QWERTY keypad, music player, stereo bluetooth and a MicroSD slot.
TouchPal is an alternative input method for mobile devices, designed and developed by Shanghai-based CooTek. It is a software application running on multiple platforms, including Android, iOS, Windows Mobile, and Windows 8. It simulates a keyboard on the screen of the device, which is used to enter text by tapping on the screen or sliding a finger between letters constructing the word. It is an optional text input method to the traditional physical keyboards and default keyboards provided by the device manufacturer.
The BlackBerry Storm is a touchscreen smartphone developed by Research In Motion. A part of the BlackBerry 9500 series of phones, it was RIM's first touchscreen device, and its first without a physical keyboard. It featured a touchscreen that responded like a button via SurePress, Research In Motion haptic feedback technology. Its competitors included Apple's iPhone, the Palm Pre, the T-Mobile G1 by HTC and the HTC Touch family.
The BlackBerry Torch 9800 is a 2010 model in the BlackBerry line of smartphones. It combines a physical QWERTY keyboard with a sliding multi-touch screen display and runs on BlackBerry OS 6. Introduced on August 3, 2010, the phone became available exclusively on AT&T on August 12, 2010.
BlackBerry Torch is a series of smartphones manufactured by BlackBerry Ltd. The lineup consists of the following:
Adaptxt is a predictive text application for mobile phones, developed by KeyPoint Technologies, a UK-based software company. The application is designed to improve text entry on mobile devices by making it faster and error-free. It achieves this by predicting the next word as well as the word being typed, continuously adapting to the user's writing-style and vocabulary.
MessagEase is an input method and virtual keyboard for touchscreen devices. It relies on a new entry system designed by Saied B. Nesbat, formatted as a 3x3 matrix keypad where users may press or swipe up, down, left, right, or diagonally to access all keys and symbols. It is a keyboard that was designed for devices like cell phones, mimicking the early cell phones' limited number of 12 keys.
Typewise is a Swiss deep tech company that builds text prediction AI. In January 2022, the company filed a patent for its technology which it claims outperforms that of Google's and Apple's.
