Digital Pen
A digital pen is an input device which captures the handwriting or brush strokes of a user and converts handwritten analog information into digital data, enabling the data to be utilized in various applications. This type of pen is used in conjunction with a graphics tablet, tablet computer, smartphone or digital notebook. The input device captures the handwriting data, that, once digitized, can be displayed on a screen. Common digital pen protocols are: * Microsoft Pen Protocol (MPP) (formerly N-trig) * Wacom AES 1.0 and 2.0 * Wacom EMR * Universal Stylus Initiative (USI) * Apple Pencil Active Projected Capacitive (APC) * Bluetooth Examples of digital pens: * Microsoft Surface Pen * Samsung S Pen * Google Pixelbook Pen * Apple Pencil Technology groups Active Active pens, such as N-trig's DuoSense Pen, include electronic components whose signals are picked up by a mobile device's built-in digitizer and transmitted to its controller, providing data on pen location, ...

Surface Pen
The Surface Pen is an active stylus and digital pen developed by Microsoft for its series of Surface computing devices. It is designed to showcase the pen computing capabilities of Microsoft's Windows 8/ 8.1, Windows 10 and Windows 11 operating systems. First generation The first Surface Pen was introduced in 2012 alongside the Surface Pro, which uses Penabled technology designed by Wacom. It features one physical button on the side to simulate a right-click when the pen comes into contact with the display, as well as an eraser tip at the top of the Pen that removes ink strokes when it comes into contact with the display. It was bundled with the Surface Pro and Surface Pro 2, but is not compatible with other models. The button on the pen doubles as a magnetic clip which can be used to attach the pen to the Surface charging port (although not while simultaneously charging the device). Although the technology was deprecated with subsequent generations and is now branded as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tablet Computers
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops (which have traditionally run off operating systems usually designed for desktops), tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by Gesture recognition, gestures executed by finger or digital pen (stylus), instead of the Computer mouse, mouse, touchpad, and Keyboard (computing), keyboard of larger computers. Portable computers can be classified according ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computing Input Devices
Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both hardware and software. Computing has scientific, engineering, mathematical, technological, and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology, and software engineering. The term ''computing'' is also synonymous with counting and calculating. In earlier times, it was used in reference to the action performed by mechanical computing machines, and before that, to human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. Computing is intimately tied to the representation of numbers, though mathemat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Peripherals
A peripheral device, or simply peripheral, is an auxiliary hardware device that a computer uses to transfer information externally. A peripheral is a hardware component that is accessible to and controlled by a computer but is not a core component of the computer. A peripheral can be categorized based on the direction in which information flows relative to the computer: * The computer receives data from an '' input device''; examples: mouse, keyboard, scanner, game controller, microphone and webcam * The computer sends data to an '' output device''; examples: monitor, printer, headphones, and speakers * The computer sends and receives data via an ''input/output device''; examples: storage device (such as disk drive, solid-state drive, USB flash drive, memory card and tape drive), modem, router, gateway and network adapter Many modern electronic devices, such as Internet-enabled digital watches, video game consoles, smartphones, and tablet computers, have ...

Light Pen
A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer's cathode-ray tube (CRT) display. It allows the user to point to displayed objects or draw on the screen in a similar way to a touchscreen but with greater positional accuracy. A light pen can work with any CRT-based display, but its ability to be used with LCDs was unclear (though Toshiba and Hitachi displayed a similar idea at the "Display 2006" show in Japan). A light pen detects changes in brightness of nearby screen pixels when scanned by cathode-ray tube electron beam and communicates the timing of this event to the computer. Since a CRT scans the entire screen one pixel at a time, the computer can keep track of the expected time of scanning various locations on screen by the beam and infer the pen's position from the latest time stamps. History The first light pen, at this time still called "light gun", was created around 1951–1955 as part of the Whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Paper
Digital paper, also known as interactive paper, is patterned paper used in conjunction with a digital pen to create handwritten digital documents. The printed dot pattern identifies the position coordinates on the paper. The digital pen uses this pattern to store handwriting and upload it to a computer. The paper The dot pattern is a two-dimensional barcode; the most common is the proprietary Anoto dot pattern. In the Anoto dot pattern, the paper is divided into a grid with a spacing of about 0.3 mm, a dot is printed near each intersection offset slightly in one of four directions, a camera in the pen typically records a 6 x 6 groups of dots. The full pattern is claimed to consist of 669,845,157,115,773,458,169 dots, and to encompass an area exceeding 4.6 million km² (this corresponds to 73 trillion unique sheets of letter-size paper). The complete pattern space is divided into various domains. These domains can be used to define paper types, or to indicate th ...

Pen Computing
Pen computing refers to any computer user-interface using a digital pen or Stylus (computing), stylus and Graphics tablet, tablet, over input devices such as a keyboard or a mouse. Historically, pen computing (defined as a computer system employing a user-interface using a pointing device plus handwriting recognition as the primary means for interactive user input) predates the use of a mouse and graphical display by at least two decades, starting with the Stylator and RAND Tablet systems of the 1950s and early 1960s. General techniques User interfaces for pen computing can be implemented in several ways. Current systems generally employ a combination of these techniques. Pointing/locator input The tablet and Stylus (computing), stylus are used as pointing devices, such as to replace a mouse. While a mouse is a ''relative'' pointing device (one uses the mouse to "push the cursor around" on a screen), a tablet is an ''absolute'' pointing device (one places the stylus where th ...

Stylus (computing)
In computing, a stylus (or stylus pen) is a small pen-shaped instrument whose tip position on a computer monitor can be detected. It is used to draw, or make selections by tapping. While devices with touchscreens such as laptops, smartphones, game consoles, and graphics tablets can usually be operated with a fingertip, a stylus can provide more accurate and controllable input. History The earliest computer-related usage for a stylus was in 1643 with Pascal's calculator. The device had rotary dials that rotated in accordance with the selected numbers; with gears, drums, and clever engineering, it was capable of addition, subtraction, multiplication and division (using 9's constant). A stylus was used to turn the dials. Later devices of this type include the Arithmometer, in the 1860s; and the Addiator, in 1920. The Addiator was a pocket mechanical adding machine that used a stylus to move tiny rigid slices of sheet-metal that were enclosed in a case. On the side of a slic ...

List Of Pen Types, Brands And Companies
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Active Pen
An active pen (also referred to as active stylus) is an input device that includes electronic components and allows users to write directly onto the display of a computing device such as a smartphone, tablet computer or ultrabook. The active pen marketplace has long been dominated by N-trig and Wacom, but newer firms Atmel and Synaptics also offer active pen designs. An active pen is generally larger and has more features than a stylus. Digital pens typically contain internal electronics and have features such as touch sensitivity, input buttons, memory, writing data transmission capabilities, and electronic erasers. The main difference between an active pen and the input device known as a passive stylus or passive pen is that although the latter can also be used to write directly onto the screen, it does not include electronics and thus lacks all of the features that are unique for an active pen: touch sensitivity, input buttons, etc. Active pen devices support most modern op ...

Anoto
Anoto Group AB (formerly C Technologies) is a Swedish cloud-based software provider (SaaS). Products Digital Pen The Digital Pen is an ink pen combined with a digital camera that digitally records everything that is written. It works by recognizing a non-repeating dot pattern printed on the paper. The non-repeating nature of the pattern means that the pen is able to determine which page is being written on, and where on the page the pen is. The dot pattern can be printed on a professional offset printing press or on a laser printer. Dots are printed in black; other colors of ink are invisible to the pen's IR sensor. On a color laser printer, CMY can be mixed to produce a near-black color that is human-readable. For offset printing, Anoto developed an ink color called "Anoto substitute black", a non-carbon-based black ink that is invisible in the IR region, allowing the user to include human-readable black marks with the dot pattern without interference.
