The document discusses the Smart Quill, a pen invented by Microsoft Research that can write on any surface and digitize handwritten notes. It contains sensors that record pen movements to recognize handwriting and transform it into text. The Smart Quill is slightly larger than a normal pen and allows the user to train it to recognize their handwriting. It can store notes locally and upload them when docked. While convenient, it has some disadvantages like size, memory issues, and cost.

2.  Introduction
 Working
 Technical specifications
 Applications
 Advantages
 Disadvantages
 Conclusion

3.  Lyndsay Williams of Microsoft Research's Cambridge
UK lab is the inventor of the Smart quill.
 A pen that can remember the words that it is used to
write, and then transform them into computer text.
 Smart Quill contains sensors that record data by the
movement of the pen, irrespective of the platform used.

4.  Smart Quill is slightly larger than an ordinary pen.
 The user trains the pen to recognize a particular
handwriting style.
 The really clever bit of technology is its ability to read
handwriting not only on paper but on any flat surface.
 The pen is filled with a cartridge

5.  Display Technology
 Handwriting recognition & signature specification
 Communication with other devices
 Memory
 Power

6.  Cyber Display is a ¼ inch diagonal LCD that uses circuitry
built on a silicon wafer.
 There is a small 3 or 4 line screen to read the information
stored in the pen.

7.  Here the user can train the pen to recognize the particular hand
writing.
 Smart Quill works by measuring the pen movement &
matching them to the movements that produce letters & words
programmed into memory.
 Password can be recognized by using the signature.

9.  This technology uses a device called Accelerometer which is
used for measuring motion.
 A tiny accelerometer in a pen used to detect the loops, arcs of
our handwriting, and transmits into a small microprocessor
that would make sense of its as text.
 Invisible writing in air is achieved through this unique
technology called accelerometers that monitors hand
movements.

10.  The data stored in the memory is uploaded to the personal
computer when it is placed into a docking station called
as “inkwell”.
 Future models could receive e-mails and pager messages
via a wireless messaging system .

11.  It has 4MB EEPROM(Electrically Erasable Programmable
Read Only Memory) Memory.
 At a time, we can store 10pages of notes can be stored locally
on the pen.

12.  Smart Quill works on AAA(Antiaircraft Artillery Battery)
 It can continuously works 12hrs with a single AAA
battery.
 The pen has automatic off system.

13.  Replace keyboard with smart quill
 Input to other devices
 Voice recording
 It also provides handheld computer applications such as
digital diary, contacts, etc.

14.  Spatial sensing system
 Security
 Hand writing recognition
 Signature recognition
 Power saving
 It also acts like a mouse
 It supports wireless communication system.

15.  Bigger in size, compared to a normal pen.
 Memory damage
 Modifying of mistakes
 Accelerometer damage

16.  The estimated cost of this pen is around $200.
 Smart quill is convenient to use.
 Keyboards becomes so tiny, we require needle-like
fingers to operate the pen.
