Screen Hotspot
A screen hotspot, in computing, provides a special area on the display screen of a computer for hyperlinking or for other GUI-based activity (such as re-direction, pop-up display, macro execution, etc.). Hotspots may not look visually distinct; however, a mouseover operation over elements such as hyperlinks, buttons or idle windows will often reveal them by changing the shape of the pointer. The corners and edges of the whole screen may also act as hotspots. Some screen savers under DOS and older versions of Windows can be configured to be activated immediately (that is, without waiting for some period of inactivity to time out) or to never activate the screen saver mode at all (even after timeout) when the mouse is moved into a particular (often configurable) corner of the screen. Hotspots are used extensively in Windows 8, where they are referred to as "hot corners". According to Fitts's law, which predicts the time it takes to reach a target area, moving mouse and trackb ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computer, computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both computer hardware, 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 calculation, calculating. In earlier times, it was used in reference to the action performed by Mechanical computer, mechanical computing machines, and before that, to Computer (occupation), 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. ...

Hyperlink
In computing, a hyperlink, or simply a link, is a digital reference providing direct access to Data (computing), data by a user (computing), user's point and click, clicking or touchscreen, tapping. A hyperlink points to a whole document or to a specific element within a document. Hypertext is text with hyperlinks. The text that is linked from is known as anchor text. A software system that is used for viewing and creating hypertext is a ''hypertext system'', and to create a hyperlink is ''to hyperlink'' (or simply ''to link''). A user following hyperlinks is said to ''navigate'' or ''browse'' the hypertext. The document containing a hyperlink is known as its source document. For example, in content from Wikipedia or Google Search, many words and terms in the text are hyperlinked to definitions of those terms. Hyperlinks are often used to implement reference mechanism (engineering), mechanisms such as tables of contents, footnotes, bibliographies, index (publishing), indexes, a ...

URL Redirection
URL redirection, also called URL forwarding, is a World Wide Web technique for making a web page available under more than one URL address. When a web browser attempts to open a URL that has been redirected, a page with a different URL is opened. Similarly, domain redirection or domain forwarding is when all pages in a URL domain are redirected to a different domain, as whewikipedia.comanwikipedia.netare automatically redirected twikipedia.org URL redirection is done for various reasons: * for URL shortening; * to prevent broken links when web pages are moved; * to allow multiple domain names belonging to the same owner to refer to a single web site; * to guide navigation into and out of a website; * for privacy protection (such as redirecting YouTube and Twitter links to Invidious and Nitter respectively or to turn AMP links into normal links); and * for hostile purposes such as phishing attacks or malware distribution. Purposes There are several reasons to use URL redire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macro (computer Science)
In computer programming, a macro (short for "macro instruction"; ) is a rule or pattern that specifies how a certain input should be mapped to a replacement output. Applying a macro to an input is known as macro expansion. The input and output may be a sequence of lexical tokens or characters, or a syntax tree. Character macros are supported in software applications to make it easy to invoke common command sequences. Token and tree macros are supported in some programming languages to enable code reuse or to extend the language, sometimes for domain-specific languages. Macros are used to make a sequence of computing instructions available to the programmer as a single program statement, making the programming task less tedious and less error-prone. Thus, they are called "macros" because a "big" block of code can be expanded from a "small" sequence of characters. Macros often allow positional or keyword parameters that dictate what the conditional assembler program gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mouseover
In the field of computing and web design, a mouseover, is an event occurring when the user moves the Cursor (user interface), cursor over a specified point on a computer monitor using a computer mouse. Also called a hover effect, mouseovers are graphical controls that respond when a user moves their mouse pointer over a designated area. This area can be a button, image, or hyperlink. This simple action can trigger different responses. The element's color or appearance can change. Additional information or interactive content can be displayed. The mouseover effect is an essential part of user interaction. It adds layers of interactivity and responsiveness to websites and applications. A mouseover is essentially an event that occurs when a user hovers their mouse pointer over a specific area on a digital interface. The user does not need to click or do any other input. Just placing the pointer over the element is enough to trigger the effect. In technical terms, a mouseover is an ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pointer (computing WIMP)
In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to input, such as a text cursor or a mouse pointer. Etymology ''Cursor'' is Latin for 'runner'. A cursor is a name given to the transparent slide engraved with a hairline used to mark a point on a slide rule. The term was then transferred to computers through analogy. On 14 November 1963, while attending a conference on computer graphics in Reno, Nevada, Douglas Engelbart of Augmentation Research Center (ARC) first expressed his thoughts to pursue his objective of developing both hardware and software computer technology to ''augment'' human intelligence by pondering how to adapt the underlying principles of the planimeter to inputting X- and Y-coordinate data, and envisioned something like the cursor of a computer mouse, mouse he initially called a ''bug'', which, in a 3-point form, could have a "drop point and 2 orthogon ...

Screen Saver
A screensaver (or screen saver) is a computer program that blanks the display screen or fills it with moving images or patterns when the computer has been idle for a designated time. The original purpose of screensavers was to prevent phosphor burn-in on CRT or plasma computer monitors (hence the name). Though most modern monitors are not susceptible to this issue (with the notable exception of OLED technology, which has individual pixels vulnerable to burnout), screensaver programs are still used for other purposes. Screensavers are often set up to offer a basic layer of security by requiring a password to re-access the device. Some screensaver programs also use otherwise-idle computer resources to do useful work, such as processing for volunteer computing projects. As well as computers, modern television operating systems, media players, and other digital entertainment systems may include optional screensavers.

Fitts's Law
Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human–computer interaction and ergonomics. The law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target. Fitts's law is used to model the act of ''pointing'', either by physically touching an object with a hand or finger, or virtually, by pointing to an object on a computer monitor using a pointing device. It was initially developed by Paul Fitts. Fitts's law has been shown to apply under a variety of conditions; with many different limbs (hands, feet, the lower lip, head-mounted sights), manipulanda (input devices), physical environments (including underwater), and user populations (young, old, special educational needs, and drugged participants). Original model formulation The original 1954 paper by Paul Morris Fitts proposed a metric to quantify the difficulty of a target se ...

Context Menu
A context menu (also called contextual, shortcut, and pop up or pop-up menu) is a menu in a graphical user interface (GUI) that appears upon user interaction, such as a right-click mouse operation. A context menu offers a limited set of choices that are available in the current state, or context, of the operating system or application to which the menu belongs. Usually the available choices are actions related to the selected object. From a technical point of view, such a context menu is a graphical control element. History Context menus first appeared in the Smalltalk environment on the Xerox Alto computer, where they were called ''pop-up menus''; they were invented by Dan Ingalls in the mid-1970s. Microsoft Office v3.0 introduced the context menu for copy and paste functionality in 1990. Borland demonstrated extensive use of the context menu in 1991 at the Second Paradox Conference in Phoenix Arizona. Lotus 1-2-3/G for OS/2 v1.0 added additional formatting options in ...

Image Map
In HTML and XHTML, an image map is a list of coordinates relating to a specific image, created in order to hyperlink areas of an image to different destinations (as opposed to a normal image link, in which the entire area of the image links to a single destination). For example, a map of the world may have each country hyperlinked to further information about that country. The intention of an image map is to provide an easy way of linking various parts of an image without dividing the image into separate image files. Server-side Server-side image maps were first supported in Mosaic (web browser) version 1.1. Server-side image maps enable the web browser to send positional information to the server about where the user clicks within an image. This allows the server to make pixel-by-pixel decisions about what content to return in response (possible methods are to use image mask layers, database queries, or configuration files on the server). The HTML code for this type of server-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
