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.
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.
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.
SMART QUILL V/S DIGITAL PEN
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.
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.
There are two techniques used for this purpose
• Accelerometer Technology• Handwriting recognition software
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.
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.
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.
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.
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.
ADVANTAGES
“Spatial sensing system” Security 3D mouse Power saving Smart Quill is all mobile
DISADVANTAGES
It has accelerometer errors. It is inconvenient with persons with
handtremors. Bigger size than normal pen.
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.
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.
