Technical Seminar Report on Smart Note Taker

CHAPTER 1 INTRODUCTION1.1 Introduction 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. 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. 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. 1 1.2 Problem Definition The Smart Note Taker is such a helpful product that satisfies the needs of the people in today's technologic and fast life.

But included softwares are NOT compatible with MAC. but this requires an IQ roll to avoid mistakes. not for novel writing. which displays the writing in the virtual environment. A single Solo pen contains enough Nano machines for 10 pages and a refill costs $10. It has a built-in cellular phone that transmits text as fax or e-mail. that is. 3. The pen continually transmits its location to the VR manager. A TL10 Solo Pen has Handwriting Recognition equivalent to Complexity 3 and costs $200 ($50 without Nano machines) 14 . or directly to a nearby computer (cost $100). if the user inserts a word.5.6 Solo Pen TL8 Solo Pens can be used in a Virtual Reality environment. An Ink Bug can be placed  on the paper to follow the Nano machines and print for real.1 More advanced versions are possible:  The TL9 Solo Pen has Handwriting Recognition equivalent to Complexity 2 and as no problem with spatial relationship. The Nano machines react to corrections. leaving a trail like ink so the user can see what he is writing or drawing. the Nano machine writing will make space for the new word as if it were a line in a text processor.  The TL10 Solo Pen has a small store of Nano machines that drop from the tip onto the surface. The Nano machines can be recalled to the Solo Pen (takes 30 seconds per page).Fig 3. The data is stored and downloaded to a computer via infrared. It identifies each CRF and where it is on the page through a very fine grid pattern that appears as light gray background shading on the CRF. establishes a new standard for ease of use in sites and speed of data transmission. Data are interpreted into fields and validation can occur immediately. Pen storage capacity can range to over 250 CRF pages.2 How does it work ? The Smart Pen optically records pen movements over a grid-enhanced paper CRF. Health Decisions takes the best technology and applies it to our clinical trials. The Smart Pen system includes the Smart Pen and a pen cradle connected to an internetenabled computer. with queries returned to sites quickly over the Internet. Health Decisions takes the best technology and applies it to our clinical trials. The process also creates an exact copy of the original CRF that can be read for notation and comparison with interpreted data fields. activating a passwordprotected Internet link to Health Decisions. the pen (which is recharged while in the dock) initiates a connection to the PC. The Smart Pen system. The Smart Pen is one of several data entry options available from our integrated clinical trials system. The Smart Pen system. Knowing what is going on in the field is limited by how quickly data are collected and transmitted. 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. When docked. a data entry option of Health Decisions’ integrated Clinical trials Management System. a data entry option of Health Decisions’ integrated Clinical trials Management System. The Pen is then placed in the cradle.3. the Smart Pen records each stroke.5. 15 . establishes a new standard for ease quickly data are collected and transmitted. As CRFs are filled out. That's how it should be done. Its mini camera captures stylus activity 100 times per second. 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.7 Solo Pen Architecture Digital pen captures the user’s handwriting. By itself. The Expedite 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. 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 hard copy backup.Fig: 3. Smart Quill isn't all space age. 3.it contains an ink cartridge so that users can see what they write down on paper. the pen works like a regular ballpoint pen. Instead.6 SMART QUILL For those who have never progressed past the hunt-and-peck method of typing. Smart Quill contains sensors that record movement by using the earth's gravity system. 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. which is paired with a Bluetooth cell phone. Dubbed Smart Quill. though -. 16 . Pens are very durable and can hold up to 100 pages . whether we write on paper or in the air. but everyone knows how to write. Unlike many handwriting recognition programs. he pointed out. Collins said. Collins said. Collins said. the handwriting recognition software translates the movements into text on-screen. Smart Quill will let them skip the step of typing up their notes. he said. including one that communicates with the PC via a radio transmitter. People could use the pen in the office to replace a keyboard. onto which users install special handwriting recognition software developed by BT Labs. In the future. and believes a product will be on shelves within two years. he said. he said.$340 or more -. daily planner. Users can enter information into these applications by pushing a button on the pen and writing down what they would like to enter. It can also be connected to printer or modem. The price tag could hover around 200 pounds sterling -. 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. There is also a small threeline screen to read the information stored in the pen. At the moment. Collins said. but the current prototype hooks up to a PC via a cable and electronic docking station called an "inkwell"."Why should people use a keyboard when they can use a pen?" said John Collins. Collins predicts there will be whole range of Smart Quill 17 . but BT Labs is working on improving the handwriting recognition software and expects it to understand cursive by next year. project manager for Smart Quill at BT Labs. the Smart Quill system analyzes movements instead of shapes. and calculator. BT is hoping to license the Smart Quill concept to interested hardware manufacturers.but no pricing has been set as of yet. Collins said. The lab has several Smart Quill models in the works. Up to 10 pages of notes can be stored locally on the pen. Many people have never learned to type quickly and accurately. This allowed BT to get rid of the electronic notepad associated with most computer pens. Smart Quill contains a few local applications such as an address book. The pen works in conjunction with a regular PC. Users write down notes in their regular handwriting and the movements are stored within Smart Quill. Once the pen is hooked up to the computer. users can scroll down the screen by tilting the pen slightly. Collins said. Future models could receive e-mails and pager messages via a wireless messaging system and could use digital signature recognition for security purposes. Smart Quill works best when users write in capital letters. 6. by frequent use of the pen. The symbols regularly used by user gets stored in the memory. e-mails and messages to PC. It contains an ink cartridge so that users can see what they write on paper . Calculators etc. contacts. 3. It enables signature verification.     Smart Quill synchronizes files. This is possible through recent technology involved in Smart Quill.pens -. Security – Security is another important feature. Smart Quill also allows third party to add on applications. 18 . Hence Passwords could be entered in the form of signatures . modems.6. Smart Quill can be used for voice record and supports speech recognition. Accelerometers senses pen/hand movement instead of shapes. This information recorded in the pen is then downloaded to PC. printers. for different applications. 3.User can train the pen to recognize a particular handwriting style.2 Advantages One of the major asset is that Smart Quill does not need a screen to work. It is used for receiving pager and e-mail messages. It also provides handheld computer applications such as digital diary. This is possible through revolutionary "Spatial Sensing" system which uses semiconductor accelerometers. It is made possible through two facilities: It enables handwriting recognition .    The information stored in the pen can be input to other devices such as mobile phones. desktop computers etc.   Smart Quill provides intuitive user interface.1 Applications  Smart Quill isn’t all space-age.Hence a simple application of Smart Quill is that it write notes on paper. Hence the pen accepts only the owner’s handwriting and rejects intruders handwriting. Voice record is made possible through ADPCM speech compression. the wireless messaging system which allows two way communication between devices .everything from a high-end model for executives to a basic one for kids to use in school. Power saving :Small screen size requires less battery power . No movement of the pen causes auto power down Smart Quill is all mobile. smaller in size and enables one-handed use. It also automatically detects left or right handed use. 19 . when twisted in air in a certain way it enables scrolling of the screen.    The Smart Quill is also a 3D-mouse. optics. Fig: 4.2 Handwriting Recognition and Signature Verification   Accelerometers measure hand movement in 2 or 3 planes. ICS and packaging.1 Display Technology Technology used in Smart Note Taker for display is Kopin Corp’s Cyber Display technology. then removed and mounted to glass. The displays are integrated to miniature monitors using its own backlighting. On board DSP converts to ASCII characters for pen applications. Cyber Display is a¼ inch diagonal LCD that uses circuitry built on a silicon wafer.1 Display Technology 4.CHAPTER 4 TECHNOLOGY 4. 20 . 1 Accelerometer Technology This technology uses a device called Accelerometer which is used for measuring motion.2. An example for Three Axes Accelerometer is Tronics +/. Record cursive letters and download to PC for decoding. 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. Consistency of handwriting. Movements are stored within the Smart Note Taker. There are 2 techniques used for this purpose : 1) Accelerometer technology 2) Handwriting recognition software 4. It records movement by using the earth's gravity system. 2) Three Axes Accelerator : This accelerometer measures acceleration in three axes. Hence it is independent of surface used. A tiny accelerometer in a pen could be used to detect the stops and starts. whether you write on paper or in the air. arcs and loops of handwriting.handed use. rather than neatness. 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. Password by signature recognition. Single character recognition on pen. 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. flat surface. vertical wall or in air. 21 . and transmit this information to a small microprocessor that would make sense of it as text. It's similar to the way a microphone detects sound. is the only condition for accuracy.    Write on paper. An example for Two Axes Accelerometer is ADXL202 Accelerometer. 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.2g accelerometer. which is to solve all the derivation problems due to this method. we have to know pen’s spatial orientation in order to withdraw the earth gravity component to the measured accelerations. we have to solve two main problems: Firstly. The handwriting recognition software translates movements in to text on screen. Handwriting transcription 2. Currently a radio receiver on the RS232 port of a pc records the pen movement for analysis via pc. Handwriting recognition 1. 22 . 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.2. The pen will power down after a period of no movement so doesn't need an on/off switch. batteries. An early hardware prototype picture shows. Handwriting Transcription In this phase. and 433Mhz 1200 Baud radio transmitter. tilt sensor . 4. we have to succeed in the double integration. PIC 8 bit microcontroller. Handwriting recognition software constitutes two major phases: 1. Pen works in conjunction with a regular PC on to which users install special handwriting recognition software. Secondly. desktop. the recorded acceleration signals are then transcript to its original form. left to right. 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.2 Handwriting Recognition Software This software embedded in the microprocessor of the pen is used to recognize handwriting of the user.Prototype of Smart Note Taker This Smart Note Taker prototype records writing on paper for radio transmission to a pocket pc. The battery life is approximately 22 hours. Fig: 4.2 the acceleration signals recorded while one is writing a small capital B 2. The first step consists in creating the reference database for the characters as for the Signatures. each symbol was reproduced several times and a mean normalized symbol was computed. The second step is the recognition process. 23 . 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. Handwriting Recognition The second huge aspect is the characters and signatures recognition. and of course the decision process is the smaller distance found. For the creation of database. 1. For this a mean signal is computed for each recorded symbol. The hardware (accelerometers plus contact detector) embedded in the pen has proved a really efficient combination for this application. 24 . the distance between this symbol and the entire database symbol is computed.2. For recognition process. Then the unknown symbol is recognized as the one with the lowest distance. the unknown symbol is first normalized. any institute. 5. On phone talks or for instructor.
