Presenting Visual Material
Every classroom is equipped with a document
camera above a work area to show written material to the students. The room
operator puts the document camera image on the monitor in the front of the
classroom and sends it to the distant classrooms. In some rooms there is
also a monitor built into the faculty console to show the faculty what the
document camera is "seeing".
For faculty who write notes as they lecture,
plane paper and marker pens work the best to produce the optimum image for
video transmission. In some rooms the White Board can be used with the
arranging of the instructor camera.
For faculty who use pre-prepared written
material, there are several issues to consider when preparing them. Video
images are wider than they are tall. Specifically, they use a 4 x 3 aspect
ratio. All this means is that when preparing
written materials, to use word-processing terms, the paper should be in the
landscape orientation instead of the standard letter orientation. When
using word-processing software, we recommend using a font size no smaller
than 36 point, preferably larger than that. Any font size smaller will be
difficult, if not impossible, to read by the students on the video
If you have existing material that cannot be
re-made, and does not meet the above criteria, we can compensate somewhat.
The document camera can zoom in and out for smaller fonts or for papers in
the letter orientation. This, of course, means that the complete paper will not be shown, so you need to use the
monitor to make sure the area to which you are referring is in the camera
Transparencies are not the ideal for
document camera usage. In most cases they are in letter orientation, and in
most of our classrooms, glare from the lights can obscure the writing.
Using the plain paper master or copes form the transparencies is
preferable. If the transparencies are the only option, we will compensate
to make them look as good as possible.
The document camera is also a good way to
show small objects to students. It is the best way to show the object to
the distance students and generally is better for your local students than
passing an object around the room or having students huddle around the

Every on-campus LCSC classroom (and the Coeur d'Alene
Outreach) has a internet accessible computer with
basic office programs. Also, there is a VGA
adapter which enables a laptop to be connected to the system. If you are in
need to use a specific software program or are planning on using your own
laptop please contact Lawrence Norris: 792-2617.
All rooms can show videotapes, though taping
of the class must stop in order to view the tape. Tape viewing is for Educational
Purposes Only. Since the distant site is an extension of the class,
showing a videotape over the system is not a breach of the copy right laws.
