CCTV and Magnification Scanning SystemsCCTV- "A closed-circuit television (CCTV) system uses a stand-mounted or hand-held video camera to project a magnified image onto a video monitor or a television (TV) screen" (from AFB information sheet). A CCTV includes the following basic features: video camera with zoom lens (hand-held or stand); monitor or television (attached camera or external); provide enlarged image of material under camera; magnification range of 2X to 60X+; switchable polarity (black text/white background or white text/black background); controls for focus, magnification, brightness, contrast; X-Y viewing table for easy material movement; variety of monitor sizes (5 inches to 20+ inches); black and white camera with color monitor (allows user selectable foreground and background colors); color camera with color monitor (view full color enlarged images); controls for foreground and background color, split image, color or b/w presentation; line markers or windowing (horizontal and/or vertical screen masking that provides a user selectable viewing window for reading); motorized viewing table Types of CCTVs
Write: OUTLOUD- similar to Intellitalk. Allows the student to set background and font colors, and then save the configuration (will look the same overtime). Speech synthesizersHardware versions- can be internal card devices or external serial devices; allow specialized software programs to integrate speech output. Depending on the software program used to read the screen, the synthesizers can work in the DOS, Win 3.x, or Win 95 environment. (Very rarely ever used).
WindowEyes- Window-Eyes was designed to add voice access to Windows 95/98. Window-Eyes is a stand-alone Windows application which gives you total control over what you hear, when you hear it, and how you hear it. Since Window-Eyes is a stand-alone Windows screen reader, it does not require a particular DOS screen reader. This means you can continue to use your existing DOS screen reader while executing DOS programs and Window-Eyes while executing Windows programs. However, Vocal-Eyes users will appreciate the consistent design used throughout Window-Eyes. Many of the familiar and powerful features of Vocal-Eyes can be found in Window-Eyes. There is no longer a need for a hardware synthesizer, as Window-Eyes uses the Microsoft SDK. Braille AccessBraille Translation SoftwareMore and more people want an ever-greater variety of materials in braille. In North America, Grade 2 braille is the standard. It includes many contracted or abbreviated words. To produce Grade 2 braille, a translation and formatting program must be used in conjunction with most braille embossers (braille printers).
