Software used in smart quill

The prototype, called Smart-Quill, has been developed by world-leading research laboratories run by BT formerly British Telecom at Martlesham, eastern England. It is claimed to be the biggest revolution in handwriting since the invention of the pen because of its usability. This sleek and stylish. He can use any surface for writing such as paper, tablet, screen or even air. The Smart-Quill isn't all space-age, although — it uses an ink cartridge to let users see what they write down on paper.

Itcontain sensors that can record movement by using the earth's gravity system, irrespective of the platform used. The pen records the information inserted by the user. The real magic is that your words of wisdom can also be uploaded to your PC through the digital inkwell, while the files that you might want to view on the pen are downloaded to Smart-Quill as well. It is an interesting idea, and it even comes with one attribute that makes entire history of pens pale by comparisonif someone else picks yourSmartQuill and tries to write with it- it wont.

Because user can train the pen to recognize a particular handwriting. Hence SmartQuill recognizes only the owners handwriting. SmartQuill is a computer housed within a pen which allows you to do what a normal personal organizer does.

Its really mobile because of its smaller size and one handed use. People can use this 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 then type them up when returning to the office.

Smart-Quill will let them skip the step of typing up their notes. It is slightly larger than any other ordinary fountain pen. Users can simply enter their information into these applications by pushing a button on the pen and writing down on paper, tablet, and screen or even on air,what they would like to enter.

The Smart-Quill does not even depend on a screen to work. The really clever bit of the technology is its ability to read handwriting not only on paper but also on any flat surface horizontal or vertical. There is also a small three-line screen to read the information stored in the pen; users can scroll down the screen by titling the pen slightly.

The user trains the pen to recognize a particular handwriting style no matterhow messy it is, as long as it is consistent, the pen can recognize it. The handwritten notes are stored on memory of this pen. The pen is then plugged into an electronic "inkwell", and text data is than transmitted to a desktop computer, printer, or modem or to a mobile telephone to send files electronically.

Up to 10 pages of notes can be stored locally on this pen. A tiny light at the tip allows writing even in the dark. The beauty is when the pen is kept idle for some time, power gets automatically off. Display technology used in Smart-Quill handwriting recognition and signature verification, display scrolls using tilt sensors, communication with other devices memory and power.

The displays are integrated to miniature monitors using its own backlighting, optics, ICS and packaging. Accelerometer measures hand movement in 2 or 3 planes,on board DSP converts to ASCII characters for pen applications towrite on paper, flat surface, vertical wall or in airSingle character recognition on pen to record cursive letters and download to a PC for decodingthe passwords by signature recognition. Smart-Quill 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. This technology uses a device which is 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 then it transmits this information to a small microprocessor that would make sense of it as a 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 se. It records movement by using the earth's gravity system, whether you write on paper or in the air.

Hence it is independent of whatever the surface is used. Movements are stored within the Smart-Quill. This information is then transmitted on to a small microprocessor that would make sense of it as a text displayed on the sleek built in screen. Two Axes Accelerometer :- This accelerometer measures acceleration in two axes. Three Axes Accelerator :- This accelerometer measures acceleration in three axes.

This Smart-Quill prototype records writing on paper for radio transmission to a pocket pc, desktop, cell phone or tablet computer. An early hardware prototype picture shows, left to right, tilt sensor , PIC 8 bit microcontroller, batteries, and Mhz Baud radio transmitter. Currently a radio receiver on the RS port of a pc records the pen movement for analysis via pc.

The battery life is approximately 22 hours. Pen works in conjunction with a regular PC on to which a user installs special handwriting recognition software.

The handwriting recognition software translates movements in to the text on screen. The recorded acceleration signals are then transcript to its original form. Here this aspect is solved using simple double integration method in order to retrace the pens tip movement on a paper.

First, we have to know pens spatial orientation in order to withdraw the earth gravity component to the measured accelerations. Second, we have to succeed in the double integration, which is to solve all the derivation problems due to this method. The algorithm which is used for handwriting transcription is the following:. 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.

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. 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. The results shown in this part are for signature recognition but they are very similar as the one obtained for the character. The corpus used for signatures was made by 10 different signatures from 10 different people.

They made 10 attempts for the database, and 5 others for the test base. In Fig 1, we can see the accelerometers signals having been recorded during Yanis signing process. Fig 2 shows the distances that are computed between the unknown signature and the ones in the database. Yanis signature was the last one learnt number 10 and we clearly see in Fig 9 that his signature was very well recognized.

In Figure 3, the X-axis represents the different symbols of the database, and the Y-axis is the distance from the unknown new symbol to the ones from the database.

By tilting the pen, user can choose applications and scroll through them without using the scroll buttons. The pen would align text if it was held in left or right hand so the text was the correct way up for left or right handed people. The Smart-Quill microcontroller gets the angle and then mapped the large screen display onto. Smart-Quill could also scroll through pages of display by tilting it in the hand and power off if no hand movement was detected or pen was flat on a desk.
