This is a concept for bridging the gap between computer and paper by combining the advantages
of both electronic world and paper . paper is still present in all offices despite the efforts to replace it with modern technology. This concept introduced here augments standard paper with
features of modern information technology. and also allows
interfacing computers using pen and paper.
Callpaper is the name of the paper that, in combination
with a pen, can act as a computer terminal allowing us to
interface computers with just pen and paper.
is the simple equation that defines this concept.
Every callpaper is similar to a paper and has a unique ID assigned to it
and a corresponding model file accessible over a network and it possesses all the
advantages of paper.
The Callpaper concept is based on a client-server architecture
that manages requests for context information essential
for the proper recognition and processing of handwritten
documents, independent of the writerâ„¢s location.
It is a large database containing
model files corresponding to Callpapers. Writers
can gain access to these files stored on the server utilising their unique IDs.the server dispatches the model file to the client site, upon recieving a request. handwriting recognition may also be
performed on the server side.
It is is the software that manages the underlying
communication with the Callpaper server on the
client site. handwriting recognition on a on a document is done according to the specifications
given in the documentâ„¢s model file. It is implemented directly in the
pen, or in a mobile phone connected to the pen through a wireless
It can describe the meaning and structure of
a document and provide instructions for recognizing the
handwritten information. model file can provide information like:
Callpaper converts handwritten, paper-based information into
an electronic device. sending a
handwritten Callpaper via email to a recipient consists of
three simple steps:
1)Calling the server:
The user dials the paper
2)Writing the paper:
writes the document having the
look and feel of normal paper, and pen captures it.
3)Sending the data::
handwriting is recognized and sent to the recipient in accordance with the specifications given in the model file.
first implemented Callpapers have been
simplemultiple choice tests.The first line specifies the paper type and other essential
attributes, such as the address of the recipient and
the type of transaction.In the client-server setup, the client performs all
processing and handwriting recognition, while the server
acts mainly as a file server for model files. At present,
the client runs on a desktop computer. But only basic interface functions, such as simple acoustic feedback are provided.
