VISION ACCESSIBILITY BUILT INTO WINDOW 7/8/10 Scott VISION ACCESSIBILITY BUILT INTO WINDOW 7/8/10 Scott Crawford Affiliated Blind of Louisiana MAGNIFIER Magnifier is the screen enlargement program built into the most resent versions of Windows. -There are three different view modes available in Magnifier. (Full, Lens, Docked) To have access to all of the view modes, graphics hotkeys must be disabled in graphics options. If Lens and Full are grayed, the system theme needs to be changed back to an “AERO” theme. -If the screen rotates 90 degrees when control-alt-arrow is pressed, the hotkeys are probably enabled. -Disable Graphics Hotkeys By Mouse: 1. Right click on black space in the desktop. 2. Left click on graphics options. 3. Click on HotKeys. 4. Left click on disable. By Keyboard: 1. Windows-d to navigate to the desktop. 2. Application menu key (may say “menu” or have picture of a square with horizontal lines across the middle. ) OR Shift-f10. 3. Arrow down to Graphics Options, enter. 4. Right arrow, then down arrow to HotKeys. 5. Right arrow, then down arrow to Disable, enter. Magnifier can be turned on in the Ease of Access Center, but it is much easier to access it through keyboard commands. -To start Magnifier, press Windows-+. A feint picture of a magnifier will appear on the screen. It stays in the same relative position on the monitor, no matter where in the magnified screen the user may be. The magnifier icon can be moved by click and dragging with the mouse. To access the Magnifier Settings, -With Mouse: left click on the magnifier icon or click on the magnifier in the task bar. -Through the keyboard: press and hold alt, then press tab until the chooser is on Magnifier, then release alt. View allows the user to switch between Full Magnification- The entire screen is magnified Lens – Like a magnifying glass that is moved around the screen. Only the box is magnified, the rest of the screen appears normal Docked – Like lens, but the magnification box does not move. As the user navigates around the screen, the area surrounding the mouse or curser is shown in the docked magnification box. The docked window can be positioned wherever the user wants, and can be moved/resized with the mouse. Options (picture of a gear) shows differently depending on which view is being used. It includes a slider that will adjust how much the magnification will change with each press of Windows - +. It is suggested to set the slider to 25%, allowing the user more control of magnification level. -“Turn on Color Inversion” takes the color currently used by the computer and switches it to its opposite. Many visually impaired users prefer reading with white or yellow print on a black background. If so, the user may want to use a white or other very light colored desktop background so that when inverted, the background becomes black (or very near black). -Tracking tells the magnifier if it should follow the pointer, keyboard focus or the text insertion point (curser). -“Fine tune what my screen fonts look like” allows the user to access “clear type”. Clear type will reduce the blurriness/pixalization that may occur at higher magnifications. -“Control whether Magnifier starts when I sign in” opens the ease of access center. There is a check box that when checked will include magnifier in the start up process. In Lens View, the options menu switches to show the lens size adjustment feature. Sliders will adjust the height and the width of the magnification lens. The tracking options are not available in this view. Utilizing Magnifier via the Keyboard Start Magnifier….. Windows - + Increase Magnification….. Windows - +(plus). Decrease Magnification…… Windows - - (minus). Invert Colors…… Control-alt I Full Screen… Control-alt-F Lens…. Control –alt – L Resize Lens… Control-Alt-R Docked… Control-alt-D Panning (moving) Zoom Window… Control-alt – Arrow Keys. Utilizing Magnifier by touch. -Use + and – symbols in the corners to change magnification amounts. At minimum, the – disappears. -Bars on sides of screens controls panning. Touch in bar and slide finger in desired direction. Once the magnified area has reached the edge of the screen, the bar on that side disappears. TEXT ENLARGMENT WITHIN PROGRAMS Zoom Zoom is available in many programs. It magnifies the document or window, but not the ribbons, taskbar, etc. -It can be controlled by using the slider in the bottom right corner of the screen. It is part of the status bar. If status bar is off, go to: -Pinch zoom: Use two fingers on the touch pad or touch screen. Spread to enlarge, slide fingers together to make things smaller. Control + or – to zoom in and out in some programs like IE -With the keyboard: f6 to move focus to the status bar. Right arrow to the zoom slider. On the minus, hit space to decrease print size. On the plus, hit space to increase print size. On percentage, hit space to open the Zoom dialogue box. Shift-f6 returns focus to the document. -Through the Ribbon: Alt-W to open the view tab on the ribbon, Q to open the Zoom dialogue box, down arrow to the desired setting or tab to the percentage box. In the percentage box, type in the desired zoom amount. Hit enter. Focus is automatically returned to the document. To leave the ribbon without making a change, hit escape. Changing Font Size -With the Keyboard 1. Select text to resize (Control A to select all text) 2. Control Shift Greater Than > makes selected text larger. Control Shift Less Than < makes selected text smaller. 3. Control-0 (zero) returns to normal size. CHANGING APPEARANCE THROUGH SETTINGS CONTROL PANEL Personalization Themes: Changing themes changes multiple settings at the same time. They can changes colors, borders, backgrounds, text sizes, etc. There are specialized themes designed for the visually impaired. -There are several differently sized high-contrast modes. -Only Aero themes work fully with Magnifier. -Below the themes are the settings for desktop background. If not using invert colors, having a dark background can make it easier for many low vision users to see. Solid colors are preferred over pictures. Pictures behind icon text can be very visually confusing. Display - Changes DPI (Dots per inch) -“Change Size of All Items” – has 3 presets or the user can click on custom sizing. Click or tab to the box with the percentage and type in the desired percentage. Custom becomes the fourth Radial button. -“Change Only The Size of Text” Allows the user to change the text size for Title Bars, Menus, Message Boxes, Palette Tiles, Icons and Tool Tips. Taskbar -Allows the user to set what will appear in the taskbar. Ease of Access Center -Provides access in a single location for numerous setting changes that can help people with disabilities. -Magnifier (discussed above) -Narrator vocalizes some of what appears on the screen. -Start on-screen Keyboard -Set up High Contrast Mouse Properties -under Pointers tab, pick desired scheme. Extra large available. Can set how pointer changes or doesn’t change colors depending on what is behind it. -Under Pointers options tab, -Motion - Change the speed and relative distance the mouse moves. Slower may be better for Low Vision users. Faster may be better for people with limited movement. -Snap To – causes the pointer to automatically move to the default button in a dialog box. May be helpful, but some users want the mouse to stay where they left it, not move on its own forcing them to relocate it. -“Display pointer trails” makes it easier to locate the mouse for many users. Circle the mouse and the trails make a circle that may be spotted. -“Show Location of Pointer When I Press Control Key” causes concentric rings to appear that encircle the mouse pointer and get smaller and smaller to help locate the pointer.

  • What Resolution Should Your Images Be?
    What Resolution Should Your Images Be? The best way to determine the optimum resolution is to think about the final use of your images. For publication you’ll need the highest resolution, for desktop printing lower, and for web or classroom use, lower still. The following table is a general guide; detailed explanations follow. Use Pixel Size Resolution Preferred Approx. File File Format Size Projected in class About 1024 pixels wide 102 DPI JPEG 300–600 K for a horizontal image; or 768 pixels high for a vertical one Web site About 400–600 pixels 72 DPI JPEG 20–200 K wide for a large image; 100–200 for a thumbnail image Printed in a book Multiply intended print 300 DPI EPS or TIFF 6–10 MB or art magazine size by resolution; e.g. an image to be printed as 6” W x 4” H would be 1800 x 1200 pixels. Printed on a Multiply intended print 200 DPI EPS or TIFF 2-3 MB laserwriter size by resolution; e.g. an image to be printed as 6” W x 4” H would be 1200 x 800 pixels. Digital Camera Photos Digital cameras have a range of preset resolutions which vary from camera to camera. Designation Resolution Max. Image size at Printable size on 300 DPI a color printer 4 Megapixels 2272 x 1704 pixels 7.5” x 5.7” 12” x 9” 3 Megapixels 2048 x 1536 pixels 6.8” x 5” 11” x 8.5” 2 Megapixels 1600 x 1200 pixels 5.3” x 4” 6” x 4” 1 Megapixel 1024 x 768 pixels 3.5” x 2.5” 5” x 3 If you can, you generally want to shoot larger than you need, then sharpen the image and reduce its size in Photoshop.

  • Printing Terms
    Printing Terms Bitmap - Also called a BMP or a raster image. A digital image that is pixel based and resolution dependent. Bit-mapped images loose sharpness and clarity when reduced or enlarged. These files are specified as a number of pixels wide by the number of pixels high. The number of bits per pixel determines the number of shades of grey or colors it can represent. Bitmaps come in many file formats, a few are GIF, JPEG, TIFF, BMP, PICT, and PSD. These types of images are created in paint programs, by scanning and by digital cameras. Bit- mapped files can also be placed or imported into a vector based file, but they remain raster images. For the promotional products industry, bit-mapped or raster images are not usually the preferred type of art for vendors to work with as they are more difficult to make adjustments such as re-sizing. CMYK - A color model where all the colors are made up of a combination of four process colors. CMYK is an abbreviation for cyan (a blue color), magenta (a red color), yellow and key (black). Color Separations - The process of separating the areas of a piece of art to be printed into its component spot or process ink colors. Each color to be printed must have its own printing plate. For example, if a piece of art was to be printed in 3 spot colors, such as PMS 185C Red, PMS 288C Blue and Black, there would be 3 plates. Each of the 3 plates would contain only the elements to be printed in a specific color.

  • Guide to Digital Art Specifications
    Guide to Digital Art Specifications Version 12.05.11 Image File Types Digital image formats for both Mac and PC platforms are accepted. Preferred file types: These file types work best and typically encounter few problems. tif (TIFF) jpg (JPEG) psd (Adobe Photoshop document) eps (Encapsulated PostScript) ai (Adobe Illustrator) pdf (Portable Document Format) Accepted file types: These file types are acceptable, although application versions and operating systems can introduce problems. A hardcopy, for cross-referencing, will ensure a more accurate outcome. doc, docx (Word) xls, xlsx (Excel) ppt, pptx (PowerPoint) fh (Freehand) cdr (Corel Draw) cvs (Canvas) Image sizing specifications should be discussed with the Editorial Office prior to digital file submission. Digital images should be submitted in the final size desired. White space around the image should be removed. Image Resolution The minimum acceptable resolution is 200 dpi at the desired final size in the paged article. To ensure the highest-quality published image, follow these optimum resolutions: • Line = 1200 dpi. Contains only black and white; no shades of gray. These images are typically ink drawings or charts. Other common terms used are monochrome or 1-bit. • Grayscale or Color = 300 dpi. Contains no text. A photograph or a painting is an example of this type of image. • Combination = 600 dpi. Grayscale or color image combined with a line image. An example is a photograph with letter labels, arrows, or text added outside the image area. Anytime a picture is combined with type outside the image area, the resolution must be high enough to maintain smooth, readable text.

  • Resolution and LPI
    Resolution and LPI Pixels: Raster graphics are made up of a grid of pixels. When viewing 100% or less on a monitor (72 dpi resolution) the individual pixels are not visible to the eye. If the dpi is lower such as in Example 1 you can see the individual pixels and can't really tell what the image is. Similar to when you zoom in on an image. Images that are only going to be viewed on the screen can be created or scanned at 72 dpi DPI or PPI: Dots per Inch or Pixels per Inch. Monitor and Scanning DPI/PPI: You will hear these terms used interchangably and in this case they refer to monitor view perimeters or the scanning resolution you select. When scanning or creating an image to be viewed on a monitor or projection device the dpi/ppi should be the same as the monitor - thus 72 dpi or a 1:1 ratio. Printer DPI/PPI: Your output device has a dpi resolution also. This is the number of dots it can create within a square inch. Example 2 shows that on a laser Example 1: Pixels Enlarged printer a number of dots can make up a halftone dot depending on the line screen selected (more about that later). When scanning or creating images that will be printed you need to capture more information about the image due to the printing process. The ratio you utilize must then be higher. But how high is enough. If your dpi is very high the file is huge.

  • Glossary of Terms
    Glossary of Terms Bandwidth: Bandwidth is the amount of information your connection to the Internet can carry, usually measured in bits per second. Banner: A banner is a graphic that is placed around a website for the use of advertising. Graphics can use static images and text, or even be animated. Banners are a great way to draw attention to special information or offers, whether it's on your site or an external site. Browser: A browser is the software you use to view web pages - in fact you're using one right now! Google Chrome, Mozilla Firefox, and Internet Explorer are some of the more common browsers, but there are others like Safari and Opera. Since each one is different, pages can vary in appearance depending on what browser is used. This has to be taken into account when designing and testing websites. CMS: Short for "Content Management System," a CMS allows a number of users to create and change website content through the use of WSYIWIG editors, without the need for HTML knowledge. Because the CMS is online, there is no need for external programs or uploading of separate page documents, and content can be published or unpublished with a single click. Compression: Compression makes files smaller for faster upload/download times, and less disk space usage. JPEGs use compression, making them ideal for web, but can lead to loss of image quality if re-saved multiple times. Cookie: A cookie is a message given to a web browser (the application you use to get online) by a web server.

  • Ft. Lauderdale – Carolinas Www
    Digital Technology Group, Inc. Tampa – Ft. Lauderdale – Carolinas www.dtgweb.com The Resolution Question DPI, PPI, LPI, Megapixels, ahhhhh! If you don’t have a good understanding of some, or all of these terms, don’t feel bad, most people are just as confused. In this article we will try to explain what each of these terms really mean, how they are used in photography & printing, and how they relate to each other. We’ll start with their definitions and a few other important terms… Dots – Dots are output by printers and are either circular or elliptical in shape and are usually one of the 3 subtractive primary colors, Cyan, Magenta, Yellow, and sometimes Black. They can overlap each other or have gaps between them (depending on resolution). Pixels – Pixels are square elements in an image file that can be any color in the spectrum or, in an image sensor (CCD) they are usually Red, Green, or Blue. They butt up against one another with no overlap or space in between. DPI (Dots Per Inch) – The ratio of the number of dots (or ellipses) that a printer can lay down in a linear inch. DPI is used to rate the resolution or quality of inkjet printers, laser printers and sometimes image- setters (the higher the number the better). These dots in some cases (inkjet printers) can overlap each other so be careful when judging the quality of a printer based just on it’s DPI rating. Scanner manufacturers most of the time, incorrectly, use DPI as a way of rating the resolution of their scanners.
