SMART NOTE TAKER ABSTRACT: 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 screen. Since, JAVA Applet is suitable for both the drawings and strings, all these applications can be put together by developing a single JAVA program. The JAVA code that we will develop will also be installed on the pen so that the processor inside the pen will type and draw the desired shape or text on the display panel.

7. SMART PEN
Vijay Rural Engineering College

11291A0478
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 andanalyze every motion, and then transmit this information to a nearby computer viainfrared, radio or direct electric signal .A Smart Pen helps a computer to recognizehandwritten or drawn input. A computer is treated as 1 level of Complexity higher inits ability to recognize the handwriting of anybody who uses a Smart Pen. Costs$50, weight is negligible.
7.1. SOLO PEN This is a progressive development of the Smart Pen : a pen with sufficientprocessing 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, narrowscreen 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).
7.1.1 More advanced versions are possible:

11291A0478
1.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). 2.The TL10 Solo Pen has a small store of nano machines 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 nano machines react to corrections, that is, if the user inserts a word, the nano machine writing will make space for the new word as if it were a line in a text processor. The Nano machines 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. 3.A TL10 Solo Pen has Handwriting Recognition equivalent to Complexity 3 and costs $200 ($50 without nanomachines) 7.1.2 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 andtransmitted. 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 transmission. 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 alight gray background shading on the CRF. The Pen is then placed in the cradle, Vijay Rural Engineering College

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 Data 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.
7.2 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 Smart Quill, 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, Smart Quill contains sensors that record movement by using the earth's gravity system, whether you write on paper or in the air. Smart Quill 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 Smart Quill 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. Smart Quill 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 Smart Quill 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 signaturerecognition 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: 1. SmartQuill isn’t all space-age. It contains an ink cartridge so that users can seewhat they write on paper .Hence a simple application of SmartQuill is that itwrite 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.

4. It is used for receiving pager and e-mail messages. This is possible throughrecent technology involved in SmartQuill, the wireless messaging system whichallows two way communication between devices . 5. Quill synchronizes files, e-mails and messages to PC. 6. SmartQuill can be used for voice record and supports speech recognition. Voice record is made possible through ADPCM speech compression. 7. SmartQuill also allows third party to add on applications.
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. Accelerometers senses pen/hand movement instead of shapes. 2. SmartQuill provides intuitive user interface. 3. 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 . 4. The SmartQuill is also a 3D-mouse, when twisted in air in a certain way it enables. 5. Scrolling of the screen. It also automatically detects left or right handed use. 6. Powersaving:Small screen size requires less battery power .

7. No movement of the pen causes auto power down. 8. SmartQuill is all mobile, smaller in size and enables one-handed use.
7.3 DISPLAY TECHNOLOGY Technology used in Smart Note Taker 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 ownbacklighting, optics, ICS and packaging.
7.3.1 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 Vijay Rural Engineering College

• Password by signature recognition Smart Note Taker 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
7.3.2 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 loopsof handwriting, and transmit this information to a small microprocessor that would makesense of it as text. There's also the possibility of viewing a full page of text through aspecial monocular magnified "virtual" screen that could be built into the end of the pen.
Invisible writing in air is achieved through this unique technology calledaccelerometer that monitors hand movements and can also be used as a ‘virtual hinge’ toscroll 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. 7.3.3 Prototype Of Smart Note Taker: 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. 7.3.4 Handwriting 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 7.3.5 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. Vijay Rural Engineering College

7.3.5.1 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 7.3.6 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. 7.3.6.1 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.

9. 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.
