INTRODUCTION
Five pen pc shortly called as P-ISM (“Pen-style Personal
Networking Gadget Package”), is nothing but the new
discovery, which is under developing stage by NEC
Corporation. P-ISM is a gadget package including five
functions: a CPU pen, communication pen with a cellular
phone function, virtual keyboard, a very small
projector, and a camera. P-ISM’s are connected with
one another through short-range wireless technology.
The whole set is also connected to the Internet through
the cellular phone function. This personal gadget in a
minimalist pen style enables the ultimate ubiquitous
computing.[1]
2 HISTORY
The conceptual prototype of the "pen" computer was built
in 2003. The prototype device, dubbed the "P-ISM", was a
"Pen-style Personal Networking Gadget" created in 2003
by Japanese technology company NEC. The P-ISM was
featured at the 2003 ITU Telecom World held in Geneva,
Switzerland.
The designer of the 5 Pen Technology ,”Toru Ichihash”,
said that” In developing this concept he asked himself –
“What is the future of IT when it is small?” The pen was a
logical choice. He also wanted a product that you could touch and feel. Further, the intent is to allow for an office
anywhere.”
However, although a conceptual prototype of the "pen"
computer was built in 2003; such devices are not yet
available to consumers.
“The design concept uses five different pens to make a
computer. One pen is a CPU, another camera, one creates
a virtual keyboard, another projects the visual output and
thus the display and another communicator (a phone).
All five pens can rest in a holding block which recharges
the batteries and holds the mass storage. Each pen
communicates wireless, possibly Bluetooth
CPU PEN
The functionality of the CPU is done by one of the pen. It
is also known as computing engine. It consists of dual
core processor embedded in it and it works with
WINDOWS operation system.The central processing unit
(CPU) is the portion of a computer system that carries out
the instructions of a computer program, and is the
primary element carrying out the computer's functions.
The central processing unit carries out each instruction of
the program in sequence, to perform the basic
arithmetical, logical, and input/output operations of the
system.
