2. INTRODUCTION
Smart quill was invented by LYNDSEY WILLIAMS of
Microsoft Research's Cambridge UK lab along with
British Telecommunications.
It is basically called the “PEN FOR THE NEW
MILLENIUM”.
It is claimed to be the biggest revolution in hand writing
since the invention of pen.
3. ABOUT SMART QUILL
Smart quill is a pen which remembers the word that
writes and transfer them into computer text.
Smart quill contains sensors that record the movement
of the pen by using earth’s gravity.
It can record the writings irrespective of the platform
used.
5. Users can enter the information into this pen by pressing start
button and write down what they like to enter.
Accelerometers sense the movement of the pen and sends to
the micro controller(PIC 8 bit MC ) which from number of
modes select the response.
MEMS technology tilt sensors are used for the tilt functions.
4 MB EEPROM is the memory used. Hence about ten pages
of notes can be stored in the pen.
Two AAA batteries are used for the power supply.
WORKING OF SMART QUILL.
6. HAND WRITING RECOGNITION
AND SIGNATURE VERIFICATION
There are two techniques used for this purpose:
Accelerometer technology
Hand writing Recognition software.
7. ACCELEROMETER TECHNOLOGY
This technology uses a device called Accelerometer which is
used for measuring motion.
A tiny accelerometer in a pen that could be used to detect the
starts and stops, arcs and loops of the hand writing and transmit
this information to the microcontroller and it would make sense
of it as text.
8. HAND WRITING
RECOGNITION SOFTWARE
This software embedded in the micro processor of the pen is
used to recognize the handwriting of the user.
TWO phases in Handwriting Recognition.
i. Handwriting Transcription
ii. Handwriting Recognition
9. SECURITY
Smart Quill pens are trained to recognize only the owner's
handwriting, making it a valuable security tool.
The inventor of the Smart Quill, Lyndsay Williams, states
“Consistency of handwriting, rather than neatness, is
the only condition for accuracy."
10. DISPLAY TECHNOLOGY
KOPIN CORP’s cyber display technology is used.
Uses high-performance single-crystal silicon
transistors.
Cyber display is ¼ inch LCD display screen.
Typical pixel size is 15 micrometer square. As a result
small display for resolution is possible.
Back light used since LCD is a non – emissive device.
11. COMMUNICATION WITH
OTHER DEVICES
The current proto type hooks up to a PC via cable and
electronic docking station called an “ink well.”
The data stored in the memory is uploaded to the personal
computer when it is placed into a docking station.
An electronic docking station is a small cabinet to which a
laptop or notebook computer can be attached for use as desktop
computer, usually have a connector for externally connected
devices such as hard drives or scanners.
.
12. Small screen size requires less battery power.
No movement of the pen causes auto power down.
Uses microcontroller PIC16C74 which has NANO WATT
XLP(Extreme Low Power) Technology
Implementation Of Back Lighting Power Down..
POWER SAVING
13. MEMORY
•Smart quill has 4 MB EEPROM.
•At a time up to up to 10 pages of notes can be stored locally on
the pen.
•The data is stored in the memory on the pen until it is uploaded
to the personal computer.
14. POWER
• AAA Battery
(44.5mm long,10.5mm in diameter &
11.5gm in weight)
• Run for 25 hrs on single battery
• Automatic power on/off system
15. ADVANTAGES
Smart quill can read on any flat surface (not only
on paper).
It is password protected.
Highly convenient and portable.
It can link to modems, printer etc
16. APPLICATIONS
The information stored in the pen can be input to other
services such as mobile phones, printers, modems, desktop
computers for different applications.
Replace keyboard with Smart Quill.
Smart Quill synchronizes files, e-mails and messages to PC.
Useful in video conferencing, classroom lectures.
It also provides handheld computer applications such as
digital diary, contacts, calculators etc.
