Today's classrooms use two principal types of visual aids: Dry-Erasable White
Boards and Video Projection. Unfortunately the properties that allow a surface
to be used for dry erase result in a terrible projection surface.
A white board's glossy surface causes a phenomenon called Hot-spotting.
This is where the centre of the projected image is so bright that the actual
projected content is obscured by a bright white glare. This leads to an all too
common situation where a classroom will have white boards fixed to the front
wall and a separate projection surface, usually a motorized or pull down screen
mounted in or on the ceiling, which drops down in front of the white board when
the lesson calls for projection.
Well, stop the presses:
Goo Systems has come up with a better solution!
One of the key characteristics of Screen Goo has always been its freedom from
Hot-spotting.
Our idea is simple but very effective: paint a premium Screen Goo surface on the
backside of a transparent, dry-erasable substrate such as Plexiglas, Lexan or
tempered glass. This is a very simple solution to implement. Simply apply two
coats of Screen Goo Finish coat first, followed by two coats of Screen Goo
Reflective second and then a final coat of Screen Goo Ultra Black to capture any
stray light. The result is a multi-purpose surface combining Screen Goo's
exceptional video quality with a dry erase capability.
Here is what you get:

You get a surface that you can project on in a
front-projection manner but can also use any dry-erase marker to write on!
Using Screen Goo in an
Interactive White Board System
Now,
add a
MimioTeach Interactive System and you can turn this into a fully
interactive whiteboard system! The MimioTeach Interactive System uses a portable
bar powered by infrared and ultrasonic technology along with a wireless USB
receiver and a stylus to turn this surface into a 4-foot by 8-foot fully
interactive whiteboard. To read more about the
MimioTeach Interactive System please go to the Mimio website.
The beauty of this system is that with Screen Goo you can
build a large (Any Size/Any Shape), state of the art projection screen and
interactive whiteboard system at a fraction of what it would
cost to do this otherwise.
