Technical Description
Two laser scanners are used to collect data about the position and
movement of the electronic pen. These operations take place in real
time, with the data being interpreted and forwarded to the host
computer.
The beams from the two scanners sweep across the writing surface,
and the laser light reflected from the pen is collected on its return
path off the scanner mirror of origin and focused on the respective
photodiode. Gathering information from the two scanners at
essentially the same time allows the exact position of the pen to be
tracked by triangulation anywhere on the writing surface.
Scanners
IRP_Install_1.fm Page 6 Monday, February 3, 2003 4:19 PM

OVERVIEW 7
For the scanner data to accurately show the pen position on the
writing surface, the scanned laser beams are aligned in a pre-
determined pattern with respect to the writing surface, both in
azimuth and in pitch. Additional encoded retro-reflectors (calibration
strips) located at the corners of the writing surface provide feedback
for establishing and maintaining these alignments.
In addition to being a passive element that reflects the laser scanner
beams for positional information, the electronic pen is an active
source of information. The status of the pen tip-switch and the two
barrel button switches are transmitted via a separate IR link to a
separate IR receiver located behind the translucent writing surface.
There the signals are decoded and sent on to the Digital Signal
Processor, where this additional information is combined with the
pen position before being sent to the host computer.

Image Adjustments
When properly installed and adjusted, the projected image should
just fill the entire screen. The edges of the image should be straight
and parallel to the edges of the screen. The distance between the
edges of the screen and the edges of the image should be no more
than 0.2”(5mm) on all sides.
To adjust the image:
1Display an image that has very clear boundaries on all four
sides. Some users may find it easier to use their computer's
Desktop screen, while others may wish to run an application
that enables them to display a full-screen, all white image (such
as a paint program, or the Webster application window with the
Current Board selected and shown in full-screen view).
2If the image on your screen is too large or too small, adjust the
projector zoom until the image nearly fills the IRP screen without
extending beyond its edges in any direction.
Refer to the documentation that came with your projector for
specific instructions on how to find and adjust the projector
zoom control.
3If the image on your screen is not in focus, adjust the projector
focus until the image is clear and sharp.
Refer to the documentation that came with your projector for
specific instructions on how to find and adjust the projector
focus control.
4If the image is not square with your screen or you cannot obtain
a clear image, contact the vendor who designed and/or installed
your custom projector installation and work with them to
complete the image adjustments.
