Soon projectors of information other than
films and documentaries became popular. Slide projectors came into homes - the
slides had to be specially made by development laboratories. But the cost of
this was soon brought into reach of most Americans by the Kodak corporation.
Slide projection devices, with their preloaded carousels, soon found their way
into business presentations. But for interactive projection nothing beat the
overhead projector which featured a lighted base, with clear sheets, the same size
as paper, that could be printed with images and even written on by a lecturer
as viewers watched from their seats. The image was projected up to a triangular
shaped device that turned the image and projected it onto a wall or screen. The
days of teachers, their faces lit with eerie low-level lighting, scribbling on
a clear sheet as students looked on is etched in the memory of a whole
generation of students.
Though overhead projectors may still be
found here and there, they have mostly been thrown over for the new LCD and DLP
projectors. These are light-weight, but still have powerful projection ability.
They are also versatile in that they may be connected to many different
devices.
One popular use of the projector is in the
home. This is a surprising development to some, but it simply makes sense. A
projector might be purchased instead of a large screen TV. The projector can
project even the most mundane television show on a large screen or even the
wall. This is normally less expensive than buying a large screen HDTV, but does
an impressive job of presenting sporting events and movies.
Of course, light-weight projectors have
become almost a required part of the baggage of sales and business people who
must travel and make presentations. Fairly spectacular multi-media
presentations can be created using Microsoft's PowerPoint or some similar tool.
Civic organizations and governmental bodies
as well as the military have all found uses for projectors in making briefings,
informing people of ancillary information at meetings and more.
Churches are jazzing up their services with
projectors. Using multimedia to get their message across. Some have even given
up printing bulletins and now conduct their entire service with Powerpoint.
This saves on paper, allows for last minute changes, and also saves labor.
Projectors
are even used by clubs and other organizations. At chess tournaments,
projectors are used to show an audience the position of play as well as the
time remaining on the chess clock. Projectors can even be used to create
holiday displays, and decorations for events such as weddings and parties.
