SMART NOTE TAKER

The Smart Note Taker is such a helpful product that satisfies the needs of the people in today's technologic and fast life. This product can be used in many ways. The Smart Note Taker provides taking fast and easy notes to people who are busy one's self with something. With the help of Smart Note Taker, people will be able to write notes on the air, while being busy with their work. The written note will be stored on the memory chip of the pen, and will be able to read in digital medium after the job has done. This will save time and facilitate life.

The Smart Note Taker is good and helpful for blinds that think and write freely. Another place, where our product can play an important role, is where two people talks on the phone. The subscribers are apart from each other while their talk, and they may want to use figures or texts to understand themselves better.

It's also useful especially for instructors in presentations. The instructors may not want to present the lecture in front of the board. The drawn figure can be processed and directly sent to the server computer in the room. The server computer then can broadcast the drawn shape through network to all of the computers which are present in the room. By this way, the lectures are aimed to be more efficient and fun. This product will be simple but powerful.

                              The product will be able to sense 3D shapes and motions that user tries to draw. The sensed information will be processed and transferred to the memory chip and then will be monitored on the display device. The drawn shape then can be broadcasted to the network or sent to a mobile device.

There will be an additional feature of the product which will monitor the notes, which were taken before, on the application program used in the computer. This application program can be a word document or an image file.

Then, the sensed figures that were drawn onto the air will be recognized and by the help of the software program we will write, the desired character will be printed in the word document.

If the application program is a paint related program, then the most
similar shape will be chosen by the program and then will be printed on the screen.

2. SYSTEM OVERVIEW

2.1. CONSTRUCTION

Since, JAVA applet is suitable for both the drawings and strings, all these  applications  can be put  together by developing a single JAVA applet program. The java code that we will develop will also be   be installed  on the  pen  so  that   the   processor   in   the    pen   will and  and type  the able to draw desired text on the display panel.

Applet:
                        Applet is a function of java which for example, is a kind of container (file) which contains a set of programs made in  java. Java is a high level  language.  It  is widely  used  in  making  various application Based  on  java.  It  is  one  of  the  best  features  of  java. The  various strings, drawings etc  will  be  made using  a class file and this  file will not   be a single file. It will be a set of files linked  together  in  a single                      

Database:
            The  system  installed in the  pen will consist of a database which  will help the processor to  recognize various words made visually in the air. Each word  written in the air will resemble to a word in thedatabase and the word  present  in the database will be printed. This will  remain the basic principle of the working of a smart note taker.

Working:

          Smart note taker will be simple but powerful. The product will be able to sense 3D shapes and motions that user tries to draw.The sensed information will be processed and transferred to the memory chip and then will be monitored on the display device. The drawn shape then can be broadcasted to the network or sent to a mobile device.
There will be an additional feature of the product that will monitor the notes, which were taken before, on the application program used in the computer. This application program can be a word document or an image file.

Then, the sensed that were drawn into the air will be recognized and with the help of the software program software we will write the desired character will be printed in the word document. If the application program is a paint related program, then the most similar shape will be chosen by the program and then will be printed on screen.

3.4. SMART PEN

                     The  Smart   Pen   is   a   device   that  resembles  a  fat  pen or   stylus, but  contains   a  tiny  computer  and  a   set  of  sophisticated sensors  that  record and  analyze  every  motion,  and  then  transmit this  information  to  a   nearby  computer  via  infrared,  radio    or direct electric signal .A Smart Pen helps a computer  to  recognize handwritten  or  drawn input. A computer  is  treated  as 1 level  of Complexity  higher  in  its  ability  to  recognize  the  handwriting of anybody  who  uses  a  Smart Pen.  Costs $50,  weight  is  negligible.

   

 3.5. SOLO PEN

This is a progressive development of the Smart Pen : a pen with sufficient processing power to recognize handwriting on its own with the equivalent of Complexity 1. It can also be used as a Smart Pen. Every Solo Pen has a long, narrow screen that displays the writing for the user to check.

The user of a Solo Pen can write on a regular writing surface, as the Solo Pen has a normal writing tip. TL8 Solo Pens have trouble with the spatial relationship of writing, so if the user writes three lines on paper and then wants to write a heading above the first line, the Solo Pen might put it a line higher or lower than desired. The user can also write in the air, but this requires an IQ roll to avoid mistakes. TL8 Solo Pens are great for short notes on the run, not for novel writing.

TL8 Solo Pens can be used in a Virtual Reality environment. The pen continually transmits its location to the VR manager, which displays the writing in the virtual environment. The data is stored and downloaded to a computer via infrared.

A Solo Pen is TL8, costs $100 and has negligible weight. It has a rechargeable A Power Cell, but do not bother about energy as long as the Pen is placed into its recharging stand (comes with the pen).

More advanced versions are possible:

·         The TL9 Solo Pen has Handwriting Recognition equivalent to Complexity 2 and as no problem with spatial relationship. It has a built-in cellular phone that transmits text as fax or e-mail, or directly to a nearby computer (cost $100).

·         The TL10 Solo Pen has a small store of nanomachines that drop from the tip onto the surface, leaving a trail like ink so the user can see what he is writing or drawing. The nanomachines react to corrections, that is, if the user inserts a word, the nanomachine writing will make space for the new word as if it were a line in a text processor. The nanomachines can be recalled to the Solo Pen (takes 30 seconds per page). An Ink Bug can be placed on the paper to follow the Nanomachines and print for real.
A single Solo pen contains enough nanomachines for 10 pages and a refill costs $10.

·         A TL10 Solo Pen has Handwriting Recognition equivalent to Complexity 3 and costs $200 ($50 without nanomachines)

How does it work ?

The  Smart Pen optically records pen  movements over a grid-enhanced paper CRF. Its mini camera captures stylus activity 100 times per second. Pen storage capacity can range to over 250 CRF pages. When docked, the pen (which is recharged while in the dock) initiates a connection to the PC. After a start prompt and the username and password are entered, data from the pen are automatically sent over the Internet to a secure Health Decisions server.

The Smart Pen is one of several data entry options available from our integrated clinical trials system.Health Decisions takes the best technology and applies it to your clinical trials.

That's how it should be done. Knowing what is going on in the field is limited by how quickly data are collected and transmitted.

The Smart Pen system, a data entry option of Health Decisions’ integrated Clinical trials Management System, establishes a new standard for ease quickly data are collected and transmitted. The Smart Pen system, a data entry option of Health Decisions’ integrated Clinical trials Management System, establishes a new standard for ease of use in sites and speed of data tanmission.

The Smart Pen system includes the Smart Pen and a pen cradle connected to an internet-enabled computer. As CRFs are filled out, the Smart Pen records each stroke. It identifies each CRF and where it is on the page through a very fine grid pattern that appears as a light gray background shading on the CRF. The Pen is then placed in the cradle, activating a password-protected Internet link to Health Decisions. Data are interpreted into fields and validation can occur immediately, with queries returned to sites quickly over the Internet. The process also creates an exact copy of the original CRF that can be read for notation and comparison with interpreted data fields.Health Decisions takes the best technology and applies it to your clinical trials.

Digital pen captures the user’s handwriting. By itself, the pen works like a regular ballpoint pen. When you use it with digital paper, you now have the added benefit of an electronic copy of the completed paperwork as well as a hardcopy backup.

              The ExpeData solution works with pen hardware from leading manufacturers both in a docking version where you need a PC to upload data and a Bluetooth version, which is paired with a Bluetooth cell phone.Pens are very durable and can hold up to 100 pages .

3.6. SMART QUILL                                            

          For those who have never progressed past the hunt-and-peck method of typing, British Telecommunications' research laboratory has come up with a prototype of an intelligent pen that records writing and translates it into text on a computer screen.

Dubbed SmartQuill, the sleek and stylish prototype pen is different from other electronic pens on the market today in that users don't have to write on a special pad in order to record what they write.

         Instead, SmartQuill contains sensors that record movement by using the earth's gravity system, whether you write on paper or in the air. SmartQuill isn't all space age, though -- it contains an ink cartridge so that users can see what they write down on paper.

"Why should people use a keyboard when they can use a pen?" said John Collins, project manager for SmartQuill at BT Labs. Many people have never learned to type quickly and accurately, but everyone knows how to write, he pointed out.

People could use the pen in the office to replace a keyboard, but the main attraction will be for users who usually take notes by hand on the road and type them up when returning to the office, Collins  said. SmartQuill will let them skip the step of typing up their notes, he said.

The pen works in conjunction with a regular PC; onto which users install special handwriting recognition software developed by BT Labs, Collins said.

The lab has several SmartQuill models in the works, including one that communicates with the PC via a radio transmitter, but the current prototype hooks up to a PC via a cable and electronic docking station called an "inkwell." It can also be connected to printer or  modem.

Users write down notes in their regular handwriting and the movements are stored within SmartQuill. Up to 10 pages of notes can be stored locally on the pen, Collins said. Once the pen is hooked up to the computer, the handwriting recognition software translates the movements into text on-screen. Unlike many handwriting recognition programs, the SmartQuill system analyzes movements instead of shapes, Collins said.

This allowed BT to get rid of the electronic notepad associated with most computer pens.

SmartQuill contains a few local applications such as an address book, daily planner, and calculator. Users can enter information into these applications by pushing a button on the pen and writing down what they would like to enter, Collins said. There is also a small three-line screen to read the information stored in the pen; users can scroll down the screen by tilting the pen slightly, he said. Future models could receive e-mails and pager messages via a wireless messaging system and could use digital signature recognition for security purposes.

BT is hoping to license the SmartQuill concept to interested hardware manufacturers, and believes a product will be on shelves within two years, Collins said. The price tag could hover around 200 pounds sterling -- $340 or more -- but no pricing has been set as of yet, he said.

At the moment, SmartQuill works best when users write in capital letters, but BT Labs is working on improving the handwriting recognition software and expects it to understand cursive by next year. In the future, Collins predicts there will be whole range of SmartQuill pens -- everything from a high-end model for executives to a basic one for kids to use in school.

Applications:

• 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.

• The information stored in the pen can be input to other devices such as mobile phones, printers, modems, desktop computers etc for different applications.
• It also provides handheld computer applications such as digital diary, contacts,

calculators etc.

•  It is used for receiving pager and e-mail messages. This is possible through recent technology involved in SmartQuill, the wireless messaging system which allows two way communication between devices .
• SmartQuill synchronizes files, e-mails and messages to PC.
•  SmartQuill can be used for voice record and supports speech recognition.

Voice  record is made possible through ADPCM speech compression.

• SmartQuill also allows third party to add on applications.    

Advantages:

• 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. Accelerometers senses pen/hand movement instead of shapes.
• SmartQuill provides intuitive user interface.
• Security – Security is another important feature. It is made possible through two facilities:

It enables handwriting recognition .User can train the pen to recognize a particular handwriting style. The symbols regularly used by user gets stored in the memory, by frequent use of the pen. Hence the pen accepts only the owner’s handwriting and rejects intruders handwriting.It enables signature verification.

             Hence Passwords could be entered in the form of signatures .

• 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.
• Power saving :Small screen size requires less battery power .
• No movement of the pen causes auto power down
• SmartQuill is all mobile, smaller in size and enables one-handed use.

3.7 DISPLAY TECHNOLOGY

Technology used in SmartNoteTaker for display is Kopin Corp’s Cyber Display technology.

Cybe Display is a¼ inch diagonal LCD that uses circuitry built on a silicon wafer, then removed  and mounted to glass. The displays are integrated to miniature monitors using its own  backlighting,optics, ICS and packaging.

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

SmartNoteTaker works by measuring the pen's movements and matching them to the movements that produce letters and words programmed into its memory. It's similar to the way a microphone detects sound. Consistency of handwriting, rather than neatness, is the only condition for accuracy.

There are 2 techniques used for this purpose :

1) Accelerometer technology

2) 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 stops and starts, arcs and loops of handwriting, and transmit this information to a small microprocessor that would make sense of it as text. There's also the possibility of viewing a full page of text through a special monocular magnified "virtual" screen that could be built into the end of the pen.                                                                                                                

                Invisible writing in air is achieved through this unique technology called accelerometer that monitors hand movements and can also be used as a ‘virtual hinge’ to scroll around the small screen on the pen and detect left or right- handed use.

 It records movement by using the earth's gravity system, whether you write on paper or in the air. Hence it is independent of surface used. Movements are stored within the SmartNoteTaker. This information is transmitted on to a small microprocessor that would make sense of it as a text displayed on the sleek built in screen.

There are 2 types of accelerometer :

1.Two Axes Accelerometer : This accelerometer measures acceleration in two axes. An

example for Two Axes Accelerometer is ADXL202  Accelerometer.

2.Three Axes Accelerator :  This accelerometer measures acceleration in three axes. An

example for Three Axes Accelerometer is Tronics +/- 2g accelerometer.

Prototype Of SmartNoteTaker

This SmartNoteTaker  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.

An early hardware prototype picture shows, left to right, tilt sensor , PIC 8 bit microcontroller, batteries, and 433Mhz 1200 Baud radio transmitter. Currently a radio receiver on the RS232 port of a pc records the pen movement for analysis via pc. 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.

Handwritnig Recognition Software

This software embedded in the microprocessor of the pen is used to recognize handwriting of the user. Pen works in conjunction with a regular PC on to which users install special handwriting recognition software. The handwriting recognition software translates movements in to text on screen.

Handwriting recognition software constitutes two major phases:

1. Handwriting transcription

2. Handwriting recognition

Handwriting transcription

In this phase, the recorded acceleration signals are then transcripted to it’s original form. Here this aspect is solved using ‘simple’ double integration method in order to retrace the pen tip movement on paper.

Method:

In order for this principle to work properly, we have to solve two main problems:

Firstly, we have to know pen’s spatial orientation in order to withdraw the earth gravity

component to the measured accelerations.

Secondly, we have to succeed in the double integration, which is to solve all the derivation  problems due to this method. 7

Handwriting recognition

The second huge aspect is the characters and signatures recognition. The hardware (accelerometers plus contact detector) embedded in the pen has proved a really efficient combination for this application.

Method

The same method is used to recognize the characters written by a single user and to find whose

signature is the one that has just been done.

We use a simple Euclidian distance as the comparison process, and of course the decision

process is the smaller distance found.

The first step  consists in creating the reference database for the characters as for the

signatures. For this a mean signal is computed for each recorded symbol.

The second step is the recognition process

1. For the creation of database, each symbol was reproduced several times and a mean normalized symbol was computed.

2. For recognition process, the unknown symbol is first normalized, the distance between this symbol and the entire database symbol is computed. Then the unknown symbol is recognized as the one with the lowest distance.

4. ADVANTAGES

·         With the help of smart note taker we can write notes on any surface even in air.That is we can write notes any time without using a paper.

·         So we get information in very fast and easy way. Hence it is time saving.

·         Smart note taker is reliable and powerful.

product is compatible with all graphics software.

·        Easy-to-use wireless connection.

·        Drawer (Contents outline, library, history).

5. FUTURE SCOPE

Companies had  succeeded  to  make  similar  products  and  put  them  in  the market. Putting a newly  invented, innovative product in the market is not easy.The prices in the market must be well observed for similar products. The prices of 2-D digital pens are about 50 dollars to 90 dollars. So  the  price  of  smart note taker  will  be  high . But this   disadvantage definitly be eliminated in near future.

6. CONCLUSION

The system will try to improve a pen, which helps people get rid of typing problems on computer by the technology, which converts your handwriting to text format on your PC.  However, the technology provides opportunity to write on air, which means it, needs no any item to convert the typing to your computer such as 3D view. Beside this, it can also be used like all other classical pens. Therefore, this device will increase the capacity of noting the texts, lessons and projects you work on. One other fact that appears is similar products generally works in a way that they store the writing by memory systems and direct the data to computer. We will vanish this time lag by using a technology that the data will be sent to PC directly not by stored. It is sure it will be hard to eliminate the other products as our rivals, but our advantage in this market will be the properties of the device, which come to be its high mobility, versatile design and its ideal weight.

The device takes a practical extent since it offers high mobility. This property may seem useless at first side but the high mobility will help the teachers or individuals, who have dynamism as they do their jobs, by giving them opportunity to write anywhere.  . On the other hand, the price of innovation will be reasonable for the sectors that can use it effectively in their business or lessons.
