Basic Idea
"it would be neat to put all of a handheld-PDA type computer in a pen"
It is the pen for the new millennium
All the computing power you need, right in your pocket.
Introduction Digital Pen
A digital pen is a battery-operated writing instrument that allows the user to digitally capture a handwritten note or drawing. Digital Pen How smart quill differs from digital pens
Digital pens require special pads for writing. But smart quill can be used on any sort of paper. Smart quill contains sensors that record movements by using earthâ„¢s gravity irrespective of the platform used. Special pad for Digital pens SMART QUILL CAN BE USED ON ANY SURFACE Features Display Screen The text written can be read on on a tiny screen on the side of the pen and used with personal information-management software, email, and other applications that will be built in. It has a light at its tip which allows the user to use it even in the dark
DISPLAY SCREEN HANDWRITING RECOGNITION AND SIGNATURE VERIFICATION
User can train the pen to recognize a particular handwriting. If someone else picks your Smart Quill and tries to write with it- it wonâ„¢t. DISPLAY SCROLLS USING SENSORS to control the cursor on a computer screen. TILT The pen's tilt sensor could also be used By tilting the pen user can chose applications and scroll through without using scroll buttons. This is done by using Micro Electro-Mechanical Systems(MEMS) tilt sensors to measure tilt angle with earth
COMMUNICATION WITH OTHER DEVICES
The current prototype hooks up to the PC via a cable and electronic docking station called as inkwell . Future models can receive email and pager messages via a wireless messaging system. Memory It uses 4MB EEPROM . Up to 10 pages of notes can be stored locally on the pen memory. The data is stored in the pen locally until it is copied to the Personal Computer. Power Smart quill works on AAA battery. It can continuously work 25 hrs with a single AAA battery. The pen has automatic on/off system. AAA Battery :Antiaircraft Artillery Battery. Size:44.5mm Long and 10.5mm in the diameter. Weight:11.5 gm. AAA BATTERY Working Smart quill works by measuring the penâ„¢s movements and matching them to the movements that produce the words and letters programmed into its memory. Consistency of handwriting rather than neatness, is the only condition for accuracy. Working Accelerometer Technology 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. Accelerometer Technology Invisible writing in air is achieved through this unique technology called accelerometer that monitors hand movements and can also be used as a Ëœvirtual hingeâ„¢ 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 SmartQuill. Types of Accelerometers in use Two Axes Accelerometer This accelerometer measures acceleration in two axes. An example for Two Axes Accelerometer is ADXL202 Accelerometer. Three Axes Accelerator This accelerometer measures acceleration in three axes. An example for Three Axes Accelerometer is Tronics +/- 2g accelerometer
HANDWRITING RECOGNITION SOFTWARE
This software embedded in the microprocessor of the pen is used to recognize handwriting of the user. The handwriting recognition software translates movements in to text on screen. Phases in handwriting recognition 1. Handwriting transcription In this phase, the recorded acceleration signals are then transcripted to itâ„¢s original form. Here this aspect is solved using Ëœsimpleâ„¢ double integration method in order to retrace the pen tip movement on paper. Method Firstly, we have to know penâ„¢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.
HANDWRITING RECOGNITION
In this phase the characters and signatures are recognized. Method We use a simple Euclidian distance as the comparison process, and of course the decision process is the smaller distance found.
HANDWRITING RECOGNITION
Steps The first step -1- consists in creating the reference database for the characters as for the signatures. The second step is the recognition process For the creation of database, each symbol was reproduced several times and a mean normalized symbol was computed. 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. PROTOC OL Fig. represents the acceleration signals recorded while one is writing a small capital B. PROTOC OL In Fig , we can see the accelerometers signals recorded during Yaniâ„¢s signing process.
ADVANTAGES "Spatial Sensing" system SmartQuill, a spatial-sensing device inside the pen detects the letterforms of the pen's movement and converts them into text. The SmartQuill does not need a screen to work ADVANTAGES Intuitive user interface User could use any surface for writing such as paper, tablet, screen or even air. It contains an ink cartridge so that users can see what they write down on paper. ADVANTAGES Security User can train the pen to recognize a particular handwriting. Hence SmartQuill recognizes only the ownerâ„¢s handwriting.
ADVANTAGES
3D-Mouse 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 ADVANTAGES Power saving SmartQuill is really a very smart pen that could control everything by itself. When the pen is kept idle for some time ,power gets automatically off. And thus saves the power.
ADVANTAGES
SmartQuill is all mobile "As more and more people are working out of the office and rather than lugging around huge laptop computers, these are something people are much more comfortable with -- writing." APPLICATIONS 2.Replace keyboard with SmartQuill 3.Input to other devices 4.Handheld computer applications 5.The wireless messaging system which allows two way communications 6.Supports speech recognition. 7.Third party to add on applications APPLICATIONS 1. To do list 2. Personal diary planner 3. Database - names and addresses 4. Synchronize files, e-mails, messages to PC 5. Clock and Alarms 6. Calculator 7. Pager
PROTOTYPE CONCLUSION The estimated cost of this futuristic pen is only $100. SmartQuill supports two factors : small size and convenient use. 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 SmartQuill is the best solution for this problem.
