INTRODUCTION : 

INTRODUCTION Lyndsay Williams of Microsoft Research's Cambridge UK lab is the inventor of Smart quill. It can remember the words that it is used to write, and then Smart Quill, has been developed by research laboratories run by British Telecom at Martlesham,England. users don't have to write on a special pad in order to record what they write.

INTRODUCTION : 

Smart Quill contains sensors that record movement by using the earth's gravity system, irrespective of the platform used. user can train the pen to recognize a particular handwriting. It’s really mobile , smaller size and skip the step of typing up their notes. INTRODUCTION

WORKING OF SMARTQUILL : 

WORKING OF SMARTQUILL Users can enter information into these applications by pushing a button on the pen and writing down. It does not need a screen to work. It is able to read hand writing. There is also a small three-line screen to read the information stored in the pen; The user can trains the pen to recognize a particular handwriting style. Up to 10 pages of notes can be stored locally on the pen. When the pen is kept idle for some time, power gets automatically off.

DISPLAY TECHNOLOGY : 

DISPLAY TECHNOLOGY Technology used for display is Kopin Corp’s Cyber Display technology. Cyber Display is a ¼ inch diagonal LCD .

HANDWRITING RECOGNITION AND SIGNATURE VERIFICATION : 

HANDWRITING RECOGNITION AND SIGNATURE VERIFICATION Accelerometers measure hand movement in 2 or 3 planes On board DSP converts to ASCII characters for pen applications Write on paper, flat surface, vertical wall or in air Single character recognition on pen Record cursive letters and download to PC for decoding Password by signature recognition SmartQuill works by measuring the pen's

HANDWRITING RECOGNITION : 

HANDWRITING RECOGNITION There are 2 techniques used for this purpose :- 1) Accelerometer technology. 2) Handwriting recognition software.

Type of Accelerometer : 

Type of Accelerometer There are 2 types of accelerometer :- 1. Two Axes Accelerometer :- This accelerometer measures acceleration in two axes. 2. Three Axes Accelerator :- This accelerometer measures acceleration in three axes.

PROTOTYPE OF SMARTQUILL : 

PROTOTYPE OF SMARTQUILL This SmartQuill prototype records writing on paper for radio transmission to a pocket pc, desktop, cell phone or tablet computer. The accelerometer tracks the angular movement of the top of the pen at an angle in the air and these angles plotted as x/y position on pc screen. The pen will power down after a period of no movement so doesn't need an on/off switch. The battery life is approximately 22 hours.

HANDWRITING RECOGNITION SOFTWARE : 

HANDWRITING RECOGNITION SOFTWARE Handwriting recognition software constitutes two major phases: 1. Handwriting transcription 2. Handwriting recognition

DISPLAY SCROLLS BY TILTING SCREEN : 

DISPLAY SCROLLS BY TILTING SCREEN The pen would align text if it was held in left or right hand so the text was the correct way up for left or right handed people. This was done by using Micro Electromechanical Systems (MEMS) tilt sensors to measure tilt angle to earth. The SmartQuill microcontroller read the angle and then mapped the large screen display onto the small 4 line display. SmartQuill could also scroll through pages of display by tilting it in the hand and power off if no hand movement was detected or pen was flat on a desk.

COMMUNICATION WITH OTHER DEVICES : 

COMMUNICATION WITH OTHER DEVICES The data stored in the memory is uploaded to the personal computer when it is placed in to a docking station. The output accelerometer signals from the pen are digitized with a National Instrument capture card with a frequency Fe of 1000Hz and a low pass filter at Fc=1/3*Fe. Future models could receive e-mails and pager messages via a wireless messaging system .This enables two-way wireless communication with other computing devices .

MEMORY : 

MEMORY SmartQuill has 4MB EEPROM memory. At a time, up to 10 pages of notes can be stored locally on the pen. SmartQuill works by measuring the pen's movements and matching them to the movements that produce letters and words programmed into its memory.

APPLICATIONS : 

APPLICATIONS 1. SmartQuill isn’t all space-age. It contains an ink cartridge so that users can see what they write on paper .Hence a simple application of SmartQuill is that it write notes on paper. This information recorded in the pen is then downloaded to PC. 2. The information stored in the pen can be input to other devices such as mobilephones, printers, modems, desktop computers etc. for different applications. 3. It also provides handheld computer applications such as digital diary, contacts, calculators etc.

APPLICATIONS : 

4. It is used for receiving pager and e-mail messages. 5. Smart Quill synchronizes files, e-mails and messages to PC. 6. Smart Quill can be used for voice record and supports speech recognition. 7. Smart Quill also allows third party to add on applications. APPLICATIONS

ADVANTAGES : 

ADVANTAGES 1. One of the major asset is that SmartQuill does not need a screen to work. This is possible through revolutionary "Spatial Sensing" system which uses semiconductor accelerometers 2. SmartQuill provides intuitive user interface. 3. Power saving 4. SmartQuill is all mobile, smaller in size and enables one-handed use. 5. The SmartQuill is also a 3D-mouse, when twisted in air in a certain way it enables scrolling of the screen. It also automatically detects left or right handed use. 6. Security

CONCLUSION : 

CONCLUSION Smart Quill will be brought to the market by the end of 2006.The estimated cost of this futuristic pen is around $600.SmartQuill supports two factors : small size and convenient use. The future of Smart Quill ensures all computation power the user needs right inside the pen. Reducing the size of handheld computers can only be taken so far before they become unusable. Keyboards become so tiny you require needle-like fingers to operate them and screens that need constant cursor controls to read simple text. The introduction of Smart Quill is the best solution for this problem.
