| Effects Of the options in the Effects tab, there is only one that are of particular importance. In the lower portion of the panel there will be several checkboxes. The third should say "Use large icons. Checking this box will enlarge the icons on the Windows desktop. Note that, if you feel so inclined, you can create a very similar effect by modifying the "icon" item in the Appearance tab. Web The Web tab contains allows you to install and manage "active desktop" items, such as animated backgrounds and real-time stock tickers. The use of these features is beyond the scope of this tutorial, but keep in mind that active desktop items are rarely accessible. Settings The Settings tab allows you to change features related directly to the performance of the actual monitor and video card hardware. The top portion of the panel should be a preview window. Immediately below the preview window there will be a short blurb describing what particular monitor and video card is being used. Below that, there will be a "colors" pull-down menu, a "screen area" slide bar and an "advanced" button. The only option in the settings tab of particular use from an accessibility standpoint is the "screen area" option, often referred to as the resolution. Lowering the screen area will cause the screen to be broken up into fewer individual pixels. This has the result of making every feature, from text to buttons to menus to icons, appear larger. The side effect is that to those accustomed to using a higher resolution, the display will appear blocky. Most modern computers use resolutions of xor x, however it is common for people with vision impairments to prefer to use a computer running at xor x. In order to change the resolution, simply slide to pointer in the "screen area" option box until the desired resolution is displayed and then click the apply button to test the resolution. A dialog box will appear explaining that the screen will now go dark and attempt to resize itself. The dialog box will further explain that if the resolution change is unsuccessful then the original resolution will be restored after 15 seconds. You should press took" button to dismiss the dialog box. If the resolution change is successful then you can press either "ok" to keep the new resolution or "cancel" to revert to your original resolution(note that even if the change is successful, the original resolution will return after fifteen seconds if you click neither button. If the change is unsuccessful and the display either remains dark or appears garbled, simply sit tight and wait for fifteen seconds. As long as you do not press any buttons on the keyboard or mouse the original display settings will return. Download 1.89 Mb. Share with your friends:
