To a specific video projector, it is viable to make adjustments to lenses that allow a 100% mapping of the image. (See pictures above). For this solution using a ordinary long video projector ,and a Microsoft HD webcam,we have a map 1x1 at 935 mm of the projection surface. This means that 1 mm(millimeter) is mapped by 1 pixel of t he picture, allowing a short 1 mm error when using the IR pen. The reasonable values of mapping are at most 3mm * 1 px, because of the size ofthe pen used. Therefore, the camera should always have a resolution and distance adjusted to the values in each case. For a bundle product, the measures of positioning the camera should be provided by t he supplier, regarding that, if the camera is capturing using 800x600 (px) , should use a distance that allows at least a i mage (projected area) of 1600x1200 (mm) for a good operation of the system (in this limit situation the camera should j ust see the projected area, and not include surrounding area.)

Hardware:This system (solution) is possible due to a interconnection of a emitting device, a acquisition device, a processing unit and theprojection of the result.
The hardware concerns are the major issue for success in this project. The devices
used, should be suitable for a general/massive solution,
Each projector and each camera have technical specifications. For our project the
information that is crucial in the angle of opening of the projector and the camera.
To a specific video projector, it is viable to make adjustments to lenses that allow
a 100% mapping of the image. (See pictures above).
For this solution using a ordinary long video projector ,and a Microsoft HD
webcam,we have a map 1x1 at 935 mm of the projection surface. This means that
1 mm(millimeter) is mapped by 1 pixel of the picture, allowing a short 1 mm error
when using the IR pen.
The reasonable values of mapping are at most 3mm * 1 px, because of the size of the pen used. Therefore, the camera should always have a resolution and distance
adjusted to the values in each case.
For a bundle product, the measures of positioning the camera should be provided by the supplier, regarding that, if the camera is
capturing using 800x600 (px) , should use a distance that allows at least a image (projected area) of 1600x1200 (mm) for a good
operation of the system (in this limit situation the camera should just see the projected area, and not include surrounding area.)

Software InformationThe software (we provide source files), creates a interface between the hardware and the applicationsoftware proprietary to the company.
This software is not intended to operate as it is. It is provided as a demonstration procedure that simulates the tracking process and
usability in writing applications and in operating system Windows 7.
There are procedures that are made with manual intervention, but that are intended to be automated in the final integrated
application with simple programming routines.
ATTENCION: All testing’s should be made using 1024x768 as screen resolution!(Once more this is a test method, the final solution will be multi resolution and auto detects the size of screen used!)
Setup Process:Now, we explain how to install our software Demo.
1 – The installation is a standard one, and should be made
carefully due to the specifications of this application.
After that you can open the writing software (MultiActionsDemo).
REMEMBER: You must allow public and private access in the windows firewall for this application:
At this time if the firewall rules are correct, you should be able to write in the screen using your pen. Try to test the smoothness of the writing and precision.
Allow to minimize, clear screen and close.
4: Now using the minimize button, you should be able to control windows 7 with the infrared pen like a
mouse, or pens, zooming in and out of pictures, or making drawings in windows paint (or for that matter using any software that
allows native windows multiwriting/multicontrol). After that you could return to drawing software.
