Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to Applied science, practical disciplines (including the design and implementation of Computer architecture, hardware and Computer programming, software). Computer science is generally considered an area of research, academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing Vulnerability (computing), security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Progr ...

True North
True north (also called geodetic north or geographic north) is the direction along Earth's surface towards the geographic North Pole or True North Pole. Geodetic north differs from ''magnetic'' north (the direction a compass points toward the Magnetic North Pole), and from grid north (the direction northwards along the grid lines of a map projection). Geodetic true north also differs very slightly from ''astronomical'' true north (typically by a few arcseconds) because the local gravitational field may not point at the exact rotational axis of Earth. The direction of astronomical true north is marked in the skies by the north celestial pole. This is within about 1° of the position of Polaris, meaning the star would appear to trace a tiny circle in the sky each sidereal day. Due to the axial precession of Earth, true north rotates in an arc with respect to the stars that takes approximately 25,000 years to complete. Around 2101–2103, Polaris will make its closest approac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile Game
A mobile game, or smartphone game, is a video game that is typically played on a mobile phone. The term also refers to all games that are played on any portable device, including from mobile phone (feature phone or smartphone), tablet, PDA to handheld game console, portable media player or graphing calculator, with and without network availability. The earliest known game on a mobile phone was a Tetris variant on the Hagenuk MT-2000 device from 1994. In 1997, Nokia launched ''Snake''. Snake, which was pre-installed in most mobile devices manufactured by Nokia, has since become one of the most played games and is found on more than 350 million devices worldwide. A variant of the ''Snake'' game for the Nokia 6110, using the infrared port, was also the first two-player game for mobile phones. Today, mobile games are usually downloaded from an app store but in some cases are also preloaded in the handheld devices by the OEM or by the mobile operator when purchased, via infrar ...

Apple Worldwide Developers Conference
The Worldwide Developers Conference (WWDC) is an information technology conference held annually by Apple Inc. The conference is usually held at Apple Park in California. The event is usually used to showcase new software and technologies in the macOS, iOS, iPadOS, watchOS, and tvOS families as well as other Apple software. WWDC is also an event hosted for third-party software developers that work on apps for iPhones, iPads, Macs, and other Apple devices. Attendees can participate in hands-on labs with Apple engineers and attend in-depth sessions covering a wide variety of topics. The first ever WWDC was held in 1983 with the introduction of Apple Basic, but it was not until 2002 that Apple started using the conference as a major launchpad for new products. Beginning in 1987, WWDC was held in Santa Clara. After 15 years in nearby San Jose, the conference moved to San Francisco, where it eventually became Apple's primary media event of the year and regularly sold out. WWDC retur ...

Apple Insider
The Apple community is a group of people interested in Apple Inc. and its products, who report information in various media. Generally this has evolved into a proliferation of websites, but latterly has also expanded into podcasts (both audio and video), either speculating on rumors about future product releases, simply report Apple-related news stories, or have discussions about Apple's products and how to use them. Such stories and discussions may include topics related to physical products like the Macintosh and iOS devices (e.g., the iPhone, iPod, and iPad); software and operating systems, like Final Cut Pro, Logic Pro X, iWork, iOS, and macOS; or even services Apple offers like iCloud, iTunes Store, or Apple Music. Apple enjoys a cult-like following for its platforms, especially following the massive increase in popularity for the brand brought about by the huge increase in sales for all its products that started around the time the company introduced the original iPod in l ...

Parallax Scrolling
Parallax scrolling is a technique in computer graphics where background images move past the camera more slowly than foreground images, creating an illusion of depth in a 2D scene of distance. The technique grew out of the multiplane camera technique used in traditional animation since the 1930s. Parallax scrolling was popularized in 2D computer graphics with its introduction to video games in the early 1980s. Some parallax scrolling was used in the arcade video game ''Jump Bug'' (1981). It used a limited form of parallax scrolling with the main scene scrolling while the starry night sky is fixed and clouds move slowly, adding depth to the scenery. The following year, ''Moon Patrol'' (1982) implemented a full form of parallax scrolling, with three separate background layers scrolling at different speeds, simulating the distance between them. ''Moon Patrol'' is often credited with popularizing parallax scrolling. '' Jungle King'' (1982), later called ''Jungle Hunt'', also had par ...

Graphical User Interface
The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based UIs, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of CLIs ( command-line interfaces), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through 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 industrial controls. The term ''GUI'' tends not to be applied to other lower-display resolution types of interfaces, such as video games (where HUD (''head-up display'') is preferred), or not including flat screens like volumetric displays because ...

Light-on-dark Color Scheme
A light-on-dark color scheme —also called black mode, dark mode, dark theme, night mode, or lights-out (mode)— is a color scheme that uses light-colored text, icons, and graphical user interface elements on a dark background. It is often discussed in terms of computer user interface design and web design. Many modern websites and operating systems offer the user an optional light-on-dark display mode. Some users find dark mode displays more visually appealing, and claim that it can reduce eye strain. Displaying white on full brightness uses roughly six times as much power as pure black on a 2016 Google Pixel, which has an OLED display. However conventional LED displays cannot benefit from reduced power consumption. Most modern operating systems support an optional light-on-dark color scheme. History Predecessors of modern computer screens, such as cathode-ray oscillographs, oscilloscopes, etc., tended to plot graphs and introduce other content as glowing traces on a bl ...

Grid Lines
In graphic design, a grid is a structure (usually two-dimensional) made up of a series of intersecting straight (vertical, horizontal, and angular) or curved lines (grid lines) used to structure content. The grid serves as an armature or framework on which a designer can organize graphic elements (images, glyphs, paragraphs, etc.) in a rational, easy-to-absorb manner. A grid can be used to organize graphic elements in relation to a page, in relation to other graphic elements on the page, or relation to other parts of the same graphic element or shape. The less-common printing term "reference grid," is an unrelated system with roots in the early days of printing. History Antecedents Before the invention of movable type a system based on optimal proportions had been used to arrange handwritten text on pages. One such system, known as the Villard Diagram, was in use at least since medieval times. Evolution of the modern grid After World War II, a number of graphic designers, incl ...

3D Interaction
In computing, 3D interaction is a form of human-machine interaction where users are able to move and perform interaction in 3D space. Both human and machine process information where the physical position of elements in the 3D space is relevant. The 3D space used for interaction can be the real physical space, a virtual space representation simulated in the computer, or a combination of both. When the real physical space is used for data input, the human interacts with the machine performing actions using an input device that detects the 3D position of the human interaction, among other things. When it is used for data output, the simulated 3D virtual scene is projected onto the real environment through one output device. The principles of 3D interaction are applied in a variety of domains such as tourism, art, gaming, simulation, education, information visualization, or scientific visualization. History Research in 3D interaction and 3D display began in the 1960s, pioneered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multi-touch Gestures
In computing, multi-touch is technology that enables a surface (a touchpad or touchscreen) to recognize the presence of more than one point of contact with the surface at the same time. The origins of multitouch began at CERN, MIT, University of Toronto, Carnegie Mellon University and Bell Labs in the 1970s. CERN started using multi-touch screens as early as 1976 for the controls of the Super Proton Synchrotron. Capacitive multi-touch displays were popularized by Apple's iPhone in 2007. Plural-point awareness may be used to implement additional functionality, such as pinch to zoom or to activate certain subroutines attached to predefined gestures. Several uses of the term multi-touch resulted from the quick developments in this field, and many companies using the term to market older technology which is called ''gesture-enhanced single-touch'' or several other terms by other companies and researchers. Several other similar or related terms attempt to differentiate between whethe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turn-by-turn Navigation
Turn-by-turn Navigation is a feature of some satellite navigation devices where directions for a selected route are continually presented to the user in the form of spoken or visual instructions. The system keeps the user up-to-date about the best route to the destination, and is often updated according to changing factors such as traffic and road conditions. Turn-by-turn systems typically use an electronic voice to inform the user whether to turn left or right, the street name, and the distance to the next turn. Mathematically, turn by turn navigation is based on the shortest path problem within graph theory, which examines how to identify the path that best meets some criteria (shortest, cheapest, fastest, etc.) between two points in a large network. History Real-time turn-by-turn navigation instructions by computer was first developed at the MIT Media Laboratory by James Raymond Davis and Christopher M. Schmandt in 1988. Their system, Backseat Driver, monitored the car's positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
