Infrared Pen
A battery, a switch and an infra-red LED operating at 940-950 nm.
the LED is polarity sensitive... the longer end is the positive side.
Calibrating
...ir pen. a picture will show you the percentage of the screen covered by the wiimote. The higher the percentage, the better the tracking.
if you aren't happy, reposition the wiimote and try again. Optimum distance should be about 2 times the height of the image, and about a 45 degree angle (so the wiimote can see the ir light of the pen)
It can also be placed on the roof.
you can add a second
Wiimote for redundancy...
or to use "Presenter mode."
presenter
The wii presenter has a variety
of presets for the buttons, BUT is
completely programmable for the
user.
(Smoothboard is simple to
use, but is very open to savable
...and interchangable...
customization. It encourages being
a producer, not just a consumer.)
needs an ir source:
(candle, ir LED..)
between the wiimote
and
the screen/whiteboard
trigger moves cursor slowly, only while you are pushing it,
for fine control... pushing buttons, etc.
using the whiteboard
You can use the various presets.
(or make your own) For writing, you
can use 3rd party software, (like
INKSCAPE!) to get a better vectoral
function.
And of course, you can make presentations like this for free
at prezi.com!
