Pens and paper are not very compatible with the technology. Managing information in handwritten forms and hard-copy documents remains an essential task for many businesses, but is often a slow, inefficient process. We will try to develop this idea to be compatible with more futures and multiple using with low cost.

 A smart pen is an input device which captures the handwriting or brush strokes of a user.  Converts handwritten analog information created using “IR Pen" into digital data, enabling the data to be utilized in various applications.  The data can then be interpreted by handwriting software and used in different applications or just as graphics.

 Extended Easily to interactive smart board by converting any surface into touch screen.

 Smart pens are portable and reliable.  Easy to use - low training and support costs.  Efficient handheld data capture that is secure and traceable.  Multiple use, that we can use smart pen as smart digital pen or smart board.

 Support high capacity storage data memory.  Reduced data entry - handwritten data is converted to text ready for processing in back office systems. As a result, our application with its features came to provide a core for other software applications depend on handwriting or controlling project using IR position.

 Detect the smart pen position.  IR sensor doesn’t exist as standalone device.  Mismatch voltage compatibility between microcontroller and IR Camera.  IR Camera give us messy data that wasn’t satisfying since the sampling rate was too slow to cope with the IR stimulus.

 Stops sending data (freezes) after working for 2-3 minutes.  File system in SD Card problem.  Convert from IR Camera coordinates to screen coordinates and calibration issues.

 Implementation IR sensor : o Extract the Wii IR camera.

o Interface Circuitry.

o built a bi-directional level shifter N-Channel MOSFET circuit converter.

 Implementation of SD card circuit.

 Configuration of XBee Wireless device.

 Building IR Pen.

 Software coding …  Microcontroller code : o Initialize I²C Bus. o Initialize SPI Bus. o SD card initialization commands. o XBee initialization commands.

o Reading IR camera sensor. o Storing in SD card or sending by XBee wireless.  C# application software : o SmartBoard Form. o SD card reader Form.

There are a huge number of applications can be implemented depending in our project such as : handwriting detecting, Signature capture supports proof of delivery or attendance, Customer, salesman, contractor … etc. Improve detecting speed with more accuracy.
