ELECTRONIC VISUAL AIDS(Click Here for Large Type)
Electronic visual aids make use of a zoom television camera to magnify your materials on to a television screen. There are different ways of doing this but all use the same principles.
When you buy the system, you can have the
camera positioned in a number of different ways:
1. Aimed down at a platform where you put your papers.
Commonly called a CCTV and manufactured by a number of
companies. The units come with montiors of various sizes and
can be color or black/white. They have variable magnification
from 2X to 60X, and can reverse polarity to white on black.
2. In a
headmount to see straight ahead (Called V-MAX).
3. Hand held, to move across the page by hand. It is sometimes called a "MOUSE-CAM"
since it resembles a computer mouse. With this, if you like, you can purchase only the
camera and use your own television monitor to view your papers. Magnification with these
are limited to 2X to 8X.
