Point-and-click Adventure Games
Point and click are one of the actions of a computer user moving a pointer (computing WIMP), pointer to a certain location on a Visual display unit, screen (''pointing'') and then pressing a button on a Computer mouse, mouse or other pointing device (''click''). An example of point and click is in hypermedia, where users click on hyperlinks to navigate from document to document. User interfaces, for example graphical user interfaces, are sometimes described as "point-and-click interfaces", often to suggest that they are very easy to use, requiring that the user simply point to indicate their wishes. Describing software this way implies that the interface can be controlled solely through a pointing device with little or no input from the Computer keyboard, keyboard, as with many graphical user interfaces. In some systems, such as Internet Explorer, moving the pointer over a link (or other GUI widget, GUI control) and waiting for a split-second will cause a tooltip to be displayed. ...

Computer User
A user is a person who uses a computer or Computer network, network Service (systems architecture), service. A user often has a user account and is identified to the system by a username (or user name). Some software products provide services to other systems and have no direct end users. End user End users are the ultimate human users (also referred to as Operator (profession), operators) of a software product. The end user stands in contrast to users who support or maintain the product such as sysops, database administrators and computer technicians. The term is used to abstract and distinguish those who only use the software from the developers of the system, who enhance the software for end users. In user-centered design, it also distinguishes the software operator from the client who pays for its development and other Stakeholder (corporate), stakeholders who may not directly use the software, but help establish its Software requirements, requirements.

Double-click
A double-click is the act of pressing a computer mouse button twice quickly without moving the mouse. Double-clicking allows two different actions to be associated with the same mouse button. It was developed by Tim Mott of Xerox Palo Alto Research Center. Often, single-clicking selects (or highlights) an object (eg the space between two characters) while a double-click selects the next object up in the selection hierarchy (eg a word), or executes the function associated with that object (eg open a file folder). Following a link in a modern web browser is accomplished with only a single click, requiring the use of a second mouse button, "click and hold" delay, or modifier key to gain access to actions other than following the link. On touchscreens, the double-click is called "double-tap"; it's not used as much as double-click, but typically it functions as a zoom feature. ("triple-tap" sometimes used to zoom the whole screen.) On icons On most systems, double-clicking an icon in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1-Click
1-Click, also called one-click or one-click buying, is the technique of allowing customers to make purchases with the payment information needed to complete the purchase having been entered by the user previously. More particularly, it allows an online shopper using an Internet marketplace to purchase an item without having to use shopping cart software. Instead of manually inputting billing and shipping information for a purchase, a user can use one-click buying to use a predefined address and credit card number to purchase one or more items. Since the expiration of Amazon's patent, there has been an advent of checkout experience platforms, such as ShopPay, Simpler, PeachPay, Zplit, and Bolt which offer similar one-click checkout flows. Patent The United States Patent and Trademark Office (USPTO) issued a patent for this technique to Amazon.com in September 1999. Amazon.com also owns the "1-Click" trademark. On May 12, 2006, the USPTO ordered a reexamination of the "One- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mystery Meat Navigation
Image:Moon by Helmut Adler.jpg, This image map is an example of mystery meat navigation. For example, finding where to click on '' Mare Humorum'' is difficult without hovering over every place (which is not possible on devices that have no cursor, such as tablets). Also, it may not be readily apparent that the image is a clickable map instead of only a simple picture of Earth's Moon. circle 215 280 75 Mare Imbrium rect 440 165 530 282 Mare Tranquillitatis circle 355 192 50 Mare Serenitatis circle 536 120 25 Mare Crisium rect 560 170 640 260Mare Fecunditatis circle 592 313 25 Mare Nectaris rect 217 131 260 172 Mare Frigoris rect 185 160 217 170 Mare Frigoris rect 125 210 150 245 Mare Frigoris rect 90 400 190 570 Oceanus Procellarum rect 190 515 280 600 Oceanus Procellarum circle 350 615 35 Mare Humorum rect 373 468 447 580 Mare Nubium circle 339 510 25 Mare Cognitum circle 354 293 25 Mare Vaporum circle 304 348 25 Sinus Aestuum circle 265 410 15 Copernicus circle 205 485 5 K ...

Graphical User Interface
A graphical user interface, or GUI, is a form of user interface that allows user (computing), users to human–computer interaction, interact with electronic devices through Graphics, graphical icon (computing), icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based user interface, text-based UIs, which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation interface, direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and Distributed control system, industrial controls. The term ''GUI'' tends not to be applied to other lower-displa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drag And Drop
In computer graphical user interfaces, drag and drop is a pointing device gesture in which the user (computing), user selects a virtual object by "grabbing" it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects. As a feature, drag-and-drop support is not found in all software, though it is sometimes a fast and easy-to-learn technique. However, it is not always clear to users that an item can be dragged and dropped, or what command is performed by the drag and drop, which can decrease usability. Actions The basic sequence involved in drag and drop is: * Move the pointer (computing WIMP), pointer to the object * Press, and hold down, the button on the computer mouse, mouse or other pointing device, to "grab" the object * "Drag" the object to the desired location by moving the pointer to this one * "Drop" the object by releasing th ...

Mouse Chording
Mouse chording is the capability of performing actions when multiple mouse buttons are held down, much like a chorded keyboard and similar to mouse gestures. One common application of mouse chording, called ''rocker navigation'', is found in Opera and in mouse gesture extensions for Mozilla Firefox. Rocker navigation typically involves the following two mouse chords: * Hold the left button and click the right button to move forward in the browser's history. * Hold the right button and click the left button to move backward in the browser's history. The operating systems Plan 9 and Oberon and the acme development environment make heavy use of mouse chording. OS/2 Presentation Manager can also use chording to copy and paste text using two buttons however Common User Access key combinations are more frequently used. Limitations Like mouse gestures, chorded actions may lack feedback and affordance and would therefore offer no way for users to discover possible chords without re ...

Triple-click
Triple-click is the action of clicking a computer mouse button three times quickly without moving the mouse. Along with clicking and double-clicking, triple-clicking allows three different actions to be associated with the same mouse button. Criticism of the double-click mechanism is even more valid for triple-clicks. However, few applications assign critical actions to a triple click. Examples of usage On text In most text processing programs and edit controls triple-clicking with the primary mouse button (the left button for right-handers) on the text selects the entire line. If the edit control is not multiline, the entire text is selected. Microsoft Word A triple-click within a paragraph in the text area selects the entire paragraph. A triple-click in the left margin (when the mouse pointer is an up-and-to-the-right arrow) selects the entire document. Microsoft Works A triple-click within a paragraph in the text area selects the line. A triple-click in the left margin (w ...

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 ...

Cursor (computers)
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 mouse he initially called a ''bug'', which, in a 3-point form, could have a "drop point and 2 orthogonal wheels".
