3. INTRODUCTION
Smart quill was invented by Lyndsey Williams
Cambridge University along with British
telecommunications.
Smart Quill is a pen that remembers the words
that writes and then transfer them into computer
text.
Smart Quill contains sensors that records
movements by using earth’s gravity irrespective of
the platform used.
4. WORKING
Smart Quill works by measuring the pen’s
movement and matching them to the
movements that produce the words and
letters programmed in its memory.
User can enter information into these pens by
simply pressing a button and accelerometers
are used to sense the movements of the pen
using earth’s gravity system.
5. SMART QUILL IS DIFFERENT FROM
DIGITAL PEN
Smart Quill does not require any surface to
write , where as I digital pen a writing surface
is required.
Smart Quill uses the normal catridge ink
available in the market, it does not require any
special ink to write.
7. FEATURES
DISPLAY SCREEN
The text written can be read on a tiny
screen on the side of a pen and it has a light
at its tip which allows the user to use it even
in the dark.

9. HANDWRITING RECOGNITION AND
SIGNATURE VERIFICATION
User can train the pen to recognize
particular handwriting.
if someone else picks your Smart Quill and
tries to write with it , it-won’t.
10. There are two techniques used for this
purpose
• Accelerometer Technology
• Handwriting recognition software
11. ACCELEROMETER TECHNOLOGY
This technology uses a device called Accelerometer
which is used for measuring motion.
A tiny accelerometer in a pen could be used to
detect the starts and stops, arcs and loops of
handwriting, and transmit this information to a
small microprocessor that would make sense of it
as text.
12. Two types of accelerometer
1. Two axes accelerometer :- measures
acceleration in two axes. Ex.ADXL202
accelerometer.
2. Three axes accelerometer :- measures
acceleration in three axes. Ex..tronics +/-
2g.
13. DISPLAY SCREEN USING TILT
SENSORS
By tilting the screen user can choose
applications and scroll through without
using scroll buttons.
This is done by using Micro Electro-
Mechanical(MEMS) tilt sensors to measure
tilt angle with earth.
14. Memory
It uses 4MB EEPROM.
Up to 10 pages of notes can be stored locally
on the pen memory.
The data is stored in the pen locally until it is
copied to the
Personal Computer.
15. POWER
Smart Quill works on AAA(Antiaircraft
Artillery Battery) battery. It can
continuously work 25 hours with a single
AAA battery.
The pen has automatic on/off system.
16. ADVANTAGES
“Spatial sensing system”
Security
3D mouse
Power saving
Smart Quill is all mobile
17. DISADVANTAGES
It has accelerometer errors.
It is inconvenient with persons with
handtremors.
Bigger size than normal
pen.
18. APPLICATIONS
Replace keyboard with smart quill.
Input to other devices.
The wireless messaging system which allows
two way communication.
Supports speech recognition.
Third party to add on applications.
19. CONCLUSION
The estimated cost of this futuristic pen is
100$.
Smart Quill is convenient to use.
Smart Quill will be boon to the users writing
in traditional languages.
