CCTV/ Portable Magnifiers
Students with Low Vision may also utilize a CCTV, which is a camera mounted device that enlarges a book or other item under the camera onto a screen. This device can then adjust the zoom, color contrast, and colors of the page for the student. There are portable options, which uses a video camera embedded in the device to enlarge the items.
You may see some students attempt to use their phones in a similar fashion. After a certain digital zoom level, the items on the phones become pixelated. The portable digital magnifier has software to smooth out the words and provides a larger zoom capacity.
