  2. Contents • Introduction • Why This Project ??? • Abstract • Features • Problems • Implementation • Recommendation • Demo

  3. Introduction Has there ever been a more amazing invention than the pen an incredibly convenient way of recording information that dates back thousands of years ??!!!

  4. Why this project ?? • 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.

  5. Abstract • 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.

  6. Abstract Cont’d • Extended Easily to interactive smart board by converting any surface into touch screen.

  7. Features • 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.

  8. Features Cont’d • 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 .

  9. Problems • 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.

  10. Problems Cont’d • 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.

  11. PIC Vs. Arduino

  12. Implementation • Implementation IR sensor : • Extract the Wii IR camera.

  13. Implementation Cont’d • Interface Circuitry .

  14. Implementation Cont’d • built a bi-directional level shifter N-Channel MOSFET circuit converter.

  15. Implementation Cont’d • Implementation of SD card circuit.

  16. Implementation Cont’d • Configuration of XBee Wireless device .

  17. Implementation Cont’d • Building IR Pen .

  18. Implementation Cont’d • Software coding … • Microcontroller code : • Initialize I²C Bus . • Initialize SPI Bus . • SD card initialization commands . • XBee initialization commands .

  19. Implementation Cont’d • Reading IR camera sensor . • Storing in SD card or sending by XBee wireless. • C# application software : • SmartBoard Form. • SD card reader Form .

  20. Recommendations • 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 .
