Video Magnifier Instruction
By: Carmen Willings
Video magnifiers are an ideal option when a student needs greater magnification and when contrast enhancement will assist the student in reading print. The video magnifier will allow access to regular print materials with the ability to enlarge and write on worksheets. The video magnifier also provides a larger field of view and gives the student a longer working distance when higher degrees of magnification is needed which is very beneficial when reading lengthier passages. This will prepare the student for adult life when most environmental, educational, and leisure reading materials will be available only in regular print.
A video magnifier (formally called a CCTV) provides electronic magnification through the use of a video camera that projects the image of what the camera is focused on, on a screen. Video magnifiers have traditionally been used for near viewing, but many video magnifiers now also have distance viewing capabilities. To make tracking and scanning easier, many video magnifiers come with a table (referred to as an XY table) that is movable in different directions. Some video magnifiers are small, portable and allow the user to carry the magnifier with them to view anything within reach including labels and packages at stores, menus, maps, medicine bottles, etc.
