SMART QUILL

P.SRIKANTH

AIM OF THE PRESENTATION

To Familiarize the people what the SMART QUILL is about. Future scope of the existing Technology.

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.

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.

How it Differs From DIGITAL PEN

DIFFERENT TYPES OF SMART QUILL

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.

FEATURES OF SMART QUILL

• Hand writing Recognition.• Signature Verification.• Security• Communication with other devices.

HAND WRITING RECOGNITION AND SIGNATURE VERIFICATION

User can train the pen to recognize the particular Hand writing.

If some one else pick your smart quill and tries to write with it – It wont.

HAND WRITING RECOGNITION AND SIGNATURE VERIFICATION

There are two techniques used for this purpose: Accelerometer technology

Hand writing Recognition software.

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.

BASIC PRINCIPLE OF OPERATION

Accelerometer sensors uses Newton's second law of motion. F = mxa

ACCELEROMETER TECHNOLOGY

There are two types of accelerometers :

1. Two axes accelerometer : This accelerometer measures the acceleration in two axes. An example for two axes accelerometer is ADXL202 accelerometer.

2. Three axes accelerometer : This accelerometer measures the acceleration in three axes. An example for three axes accelerometer is Tronics +/- 2g accelerometer.

HAND WRITINGRECOGNITION 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 Transcriptionii. Handwriting Recognition

HAND WRITING TRANSCRIPTION

In this phase, the recorded acceleration signals are then transcript to it’s original form.

HAND WRITING RECOGNITION

• In this phase the characters and signatures are recognized.

METHOD: We use simple Euclidian Distance as the comparison process and of course the decision process is the

smaller distance found.

SECURITYSmart 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."

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.

COMMUNICATION WITH OTHER DEVICESThe 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..

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

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.

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

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

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.

DISADVANTAGES

It is inconvenient for the persons with hand tremors.

Bigger size than normal pen.

It is expensive.

FUTURE SCOPE

It can be further developed for cursive writings and traditional languages.

Refabrication and Reducing the size.

Cost Reduction.
