Screen Magnifier
A screen magnifier is software that interfaces with a computer's graphical output to present enlarged screen content. By enlarging part (or all) of a screen, people with visual impairments can better see words and images. This type of assistive technology is useful for people with some functional vision; people with visual impairments and little or no functional vision usually use a screen reader. Use The simplest form of magnification presents an enlarged portion of the original screen content, the 'focus', so that it covers some or all of the full screen. This enlarged portion should include the content of interest to the user and the pointer or cursor, also suitably enlarged. As the user moves the pointer or cursor the screen magnifier should track with it and show the new enlarged portion. If this tracking is jerky or flickers it is likely to disturb the user. Also, the pointer or cursor may not be the content of interest: for example, if the user presses a keyboard shortcuts ...

GNOME
A gnome () is a mythological creature and diminutive spirit in Renaissance magic and alchemy, introduced by Paracelsus in the 16th century and widely adopted by authors, including those of modern fantasy literature. They are typically depicted as small humanoids who live underground. Gnome characteristics are reinterpreted to suit various storytellers and artists. Paracelsus's gnome is recognized to have derived from the German miners' legend about or , the "metallurgical or mineralogical demon", according to Georg Agricola (1530), also called (literal Latinization of ''Bergmännlein'', "mountain manikin") by Agriocola in a later work (1549), and described by other names such as (sing. ; Latinization of German ). Agricola recorded that, according to the legends of that profession, these mining spirits acted as miming and laughing pranksters who sometimes threw pebbles at miners, but could also reward them by depositing a rich vein of silver ore. Paracelsus also called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Magnifying Glass
A magnifying glass is a convex lens—usually mounted in a frame with a handle—that is used to produce a magnified image of an object. A magnifying glass can also be used to focus light, such as to concentrate the Sun's radiation to create a hot spot at the focus for fire starting. Evidence of magnifying glasses exists from antiquity. The magnifying glass is an icon of detective fiction, particularly that of Sherlock Holmes. An alternative to a magnifying glass is a sheet magnifier, which comprises many very narrow concentric ring-shaped lenses, such that the combination acts as a single lens but is much thinner. Use The convex lens of a magnifying glass can be used to produce a magnified image An image or picture is a visual representation. An image can be Two-dimensional space, two-dimensional, such as a drawing, painting, or photograph, or Three-dimensional space, three-dimensional, such as a carving or sculpture.

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens (optics), lens which reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections. The simpler Dioptrics, dioptric (purely refraction, refractive) form of the lens was first proposed by Georges-Louis Leclerc, Comte de Buffon, and independently reinvented by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. The Catadioptric system, catadioptric (combining refraction and reflection) form of the lens, entirely invented by Fresnel, has outer Prism (optics), prismatic elements that use total internal reflection as well as refraction to capture more oblique light from the light source and add it to the beam, making it visible at greater distances. The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional ...

Virtual Magnifying Glass
Virtual Magnifying Glass is an Open-source software, open-source, screen magnifier, screen magnification tool for Microsoft Windows and Linux. Virtual Magnifying Glass is designed for the visual impairment, visually impaired and others who need to magnify part of the computer display. Unlike most similar programs, it does not open a separate Window (computing), program window for the magnification but instead puts a movable magnifying glass on the screen. Virtual Magnifying Glass works on a variety of platforms (Windows, Linux, FreeBSD, Mac OS) due to being developed with the Free Pascal compiler. There is no charge for the software.

Magnifier (Windows)
Magnifier, formerly Microsoft Magnifier, is a screen magnifier app intended for visually impaired people to use when running Microsoft Windows. When it is running, it creates a bar at the top of the screen that greatly magnifies where the mouse is. ''Magnifier'' was first included as a sample in the Active Accessibility SDK/RDK for Windows 95 and later made a standard Windows utility starting with Windows 98. Prior to Windows Vista, Magnifier could be used to magnify the screen up to 9 times its normal size. Windows Vista and later allow up to 16× magnification. In Windows Vista, ''Magnifier'' uses WPF, which in turn uses vector images to render the content. As a result, the rendered magnified image is sharp and not pixelated. However, this is useful only for Windows Presentation Foundation applications. Non-WPF applications are still magnified the traditional way. Also, due to a change introduced in WPF 3.5 SP1, this functionality is lost if .NET Framework 3.5 SP1 is install ...

GNOME Shell
GNOME Shell is the graphical shell of the GNOME desktop environment starting with version 3, which was released on April 6, 2011. It provides basic functions like launching applications and switching between windows. GNOME Shell replaced GNOME Panel and some ancillary components of GNOME 2. GNOME Shell is written in C and JavaScript as a plugin for Mutter. In contrast to the KDE Plasma Workspaces, a software framework intended to facilitate the creation of multiple graphical shells for different devices, the GNOME Shell is intended to be used on desktop computers with large screens operated via keyboard and mouse, as well as portable computers with smaller screens operated via their keyboard, touchpad or touchscreen. History The first concepts for GNOME Shell were created during GNOME's ''User Experience Hackfest'' 2008 in Boston. After criticism of the traditional GNOME desktop and accusations of stagnation and lacking vision, the resulting discussion led to the an ...

Compiz
Compiz () is a compositing window manager for the X Window System, using 3D graphics hardware to create fast compositing desktop effects for window management. Effects, such as a minimization animation or a cube workspace, are implemented as loadable plugins. Because it conforms to the Inter-Client Communication Conventions Manual, ICCCM conventions, Compiz can be used as a substitute for the default Mutter (window manager), Mutter or Metacity, when using GNOME Panel, or KWin in KDE Plasma Workspaces. Internally Compiz uses the OpenGL library as the interface to the graphics hardware. Hardware requirements Initially, Compiz only worked with 3D hardware supported by Xgl. Most NVIDIA and AMD Graphics, AMD graphics cards are known to work with Compiz on Xgl. Since May 22, 2006 Compiz works on the standard X.Org Server, by using AIGLX. Besides Intel GMA graphics cards, AIGLX also supports using AMD graphics cards (including R300 and newer cards) using the open-source driver which su ...
