The interactive projector
is quite similar to a traditional projector in that it display images and
information from a computer. However, it
is revolutionary in that it may be projected on to just about any surface, so
it does not require a special screen or board.
Furthermore, the interactive projector comes with a pen that can write
on the projection from up to 25 feet away, and functions much like a wireless
mouse with writing capabilities.
This tool allows for
interactivity between teachers and students in the classroom. Teachers are able to project information,
images, videos, etc. anywhere in the classroom, and can navigate with the
mouse, also from multiple locations in the room. Students can use the tool as an alternative
to a blackboard (or an IWB), answering questions or delivering presentations
without ever having to leave their seat.
Interactive projectors
have several advantages over IWBs.
First, they can be more economic, as there is no special board or
attachment that has to be purchased along with it. Unlike an IWB, the interactive projector can
be written on with its accompanying pen in the air, because the projector is in
constant communication with the pen, so it never needs to actually touch a
surface. Also, interactive projectors
have the advantage of never needing to be calibrated, making it easy to share
between teachers or even classrooms.
