Smart Quill

Abstract  on Smart Quill seminar topic

In the market there are various pen’s available but none of them performs operations other than writing. This paper focuses on the extraordinary invention of a pen that performs operation more than writing. Smart Quill is a computer housed within a pen. This pen replaces the keyboard in the office, but it is highly convenient for people who takes notes by hand. The present fashion of computations has started desiring small computers. This has made computer manufacturing companies to go for roughly tool similar to computers. Reducing the size of the handheld computers can only be taken so far before they become impracticable. Keyboards become so infinitesimal you require needle-like fingers to operate them and screens that necessitate stable indicator control to study trouble-free text. 

Introduction


In this paper we are going to discuss about a pen that will retain the words that it is used to write, and then convert them into computer text. The idea that "it would be neat to put all of a handheld-PDA type computer in a pen". It is claimed to be the biggest revolution in handwriting since the invention of the pen. Users don't have to write on a special pad in order to record what they write. User could use this pen on any platform for writing such as tablet, screen or even air. The Smart Quill is not all space-age, though it contains an ink sealed unit so that users can witness what they write down on paper. Smart Quill contains sensors that trace movement by using the earth's solemnity system, irrespective of the device used. The pen report the information inserted by the user. Your words of data can also be uploaded to your PC through the “digital inkwell”, while the files that you might want to outlook on the pen are downloaded from Smart Quill as well. The Smart Quill overcomes the problem of typing.with subscripts and superscripts in a slightly smaller font size. This is acceptable. 

Working of Smart Quill


Smart Quill measures the movement of pen and then matches them to the movements that produce the words and letters programmed into its memory. It is a bit larger than an ordinary fountain pen. By pushing a button on the pen and writing what the user would like to enter, users can enter information and it does not necessarily need a screen. This technology has the ability to read handwriting not only on paper but on any horizontal or vertical flat surface. There is a three-line screen for reading the information stored in the pen. The users might also scroll down the screen by slightly tilting the pen. The user trains the pen to recognize a particular handwriting , as long as the handwriting is consistent. Even if the handwriting is quite messy the pen can recognize it. The notes are stored on the pen’s hard disk 

There are two techniques used:


1. Accelerometer technology
2. Handwriting recognition software.

The 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 a n d 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 Smart Quill. 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.

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

Handwriting Transcription


In this phase, 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 pen tip movement on paper.

Handwriting Recognition


The second huge aspect is the characters and signatures recognition. The hardware (accelerometers plus contact detector) embedded in the pen has

Advantages on Smart Quill

i. SmartQuill can read on any flat surface and not only on paper.
ii. SmartQuill is protected by password.
iii. It is portable and highly convenient.
iv. With modems, printers etc it can be linked.

Disadvantages on Smart Quill

i. SmartQuill has accelerometer errors.
ii. People with hand tremours have inconvenience with it.
iii. It has a size bigger than a normal pen.
iv. Due to the thermal variations in the spring errors are introduced in the system. 

Conclusion


This paper concentrates on providing people with a pen that performs much more functionality than an ordinary pen. We have discussed in detail about how SmartQuill works. It is a big support for people who takes notes on
paper. This paper includes the various features and how they are useful. Also, in this paper we have discussed the various advantages and disadvantages of this extraordinary pen. This paper includes the details on how the idea that
came to the inventor in her dreams work.
