3. 1. Introduction
Five pen pc the new discovery, which is under developing stage by NEC
Corporation. PISM is a gadget package including five Functions: a CPU pen,
communication pen, 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 minima list pen style enables the ultimate ubiquitous
computing.
2. Pen Technology
There are many kinds of pen technologies examples are as follow:
• CPU pen
• Camera Pen
• Virtual key board
• LED Projector
• Communication Pen
2.1 PC Pen Technology
It consists of five pens , CPU pen, Communication pen, Camera pen,
Keyboard pen, Monitor pen. Each of the pens in a set has special purpose. One
shows the monitor on the wall the other make a keyboard on the flat desk on table
top etc, each of these pens are interconnected via Bluetooth.

4. This “pen sort of instrument” produces both the monitor as well as the
keyboard on any flat surfaces from where you can perform function you would
normally do on your desktop computer.
In the revolution of miniature computers, scientists have made great
developments with Bluetooth technology… this is the forthcoming computers you
can carry within your pockets.
Some features are as:
• Connected with a wireless technology (Bluetooth).
• Connected to internet through Cellular Function.
2.2 LED Projector
The role of monitor is taken by LED Projector which projects on the screen. The size
of the projector is of A4 size. It has the approximate resolution capacity of 1024 X
768. Thus it is gives more clarity and good picture.
2.3 Virtual Keyboard
The Virtual Laser Keyboard (VKB) is the ULTIMATE new gadget for PC users. The
VKB emits laser on to the desk where it looks like the keyboard having QWERTY
arrangement of keys i.e., it uses a laser beam to generate a full-size perfectly
operating laser keyboard that smoothly connects to a PC and Most of the handheld
devices (PDA's, tablet PC's). The laser keyboard acts exactly like any other
"ordinary" keyboard:
Features of virtual keyboards are:

5. 1.VKB settings can be changed by Sound:
2.Controllable Virtual Keyboard sound effects (key clicks)
3.Connection: Connection to the appropriate Laptop/PC port
4.Intensity: Intensity of the projected Virtual Keyboard
5.Timeouts: coordinated timeouts to conserve the Virtual Keyboard's battery life
6.Sensitivity: adjustable sensitivity of the Virtual Keyboard
7.Auto-repeat: Allows the VKB to automatically repeat a key based on prescribed
parameters.
2.4 CPU Pen
• The functionality of the CPU is done by one of the pen.
• Works with windows operating system.
• Having Dual Core Processor used.
• It is also known as computing engine.
2.5 Communication Pen
• This pen uses P-ISMs phenomenon. It connects all the pen through tri
wireless modes (Bluetooth, 802.11 B/G and cellular.
• Wireless Bluetooth technology.
• Connected to internet through cellular phone function.

6. • Uses Wi-Fi technology.
• Exchange information with wireless connection.
2.6 Digital Camera Pen
• It is useful in video recording, video conferencing simply as a webcam.
• Connected with other devices via Bluetooth.
• It is a 360 degree visual communication device.
3. Merits
• Portable( It consists of five pens which you can easily carry from one place to
another in your pocket and use there).
• Feasible (Possible to do easily your work).
• Wi-Fi technology (Wireless internet card installed in it so you can use Wi-Fi
technology.
• Excellent battery timing last up to 6+ Days.
• Everything is wireless.
• As using 802.11 B/G which has a transfer rate of 11Mbps. That’s why wireless
does not affect the speed.
4. Demerits
• It is very expensive.
• Its battery is good, but not repairable.
• Virtual keyboard made on the desktop is not new (advanced).
• The position of the projector pen is very important which is not normally
easy to do.
• Flat surface is required for projector having white colour.

7. • Flat surface is also required for keyboard and it is not easy to use as normal.
• If one of the pen gets damaged, you cannot operate this device(Pen PC).
5. What is Pen Computing?
Pen computing as a field broadly includes computers and applications in which a
pen is the main input device. This field continues to draw a lot of attention from
researchers because there are a number of applications where pen is the most
convenient form of input. These include:
• Preparing a first draft of a document and concentrating on content creation.
• A socially acceptable form of capturing information in meetings, that is
quieter than typing and creates minimal visual barrier.
• Applications that need privacy.
• Entering letters in ideographic languages like Chinese and Japanese; where
the size of the character set makes keyboard-style input cumbersome or
infeasible
• Entering non-letter entries like graphics, music and gestures.
• Interaction with multi-modal systems.
6. Conclusion
As this computer is composed of five pens, so it is more portable than a
normal computer. Its performance is better than a normal computer but there are
some exceptional cases which limits its performance for example you need white flat
screen to use as a monitor and a flat surface for a keyboard. If any one of the pens
get a fault or the user loses it then whole of the computer is worthless and will not
be able to operate. It does not have USB ports and CD-ROM, due to which the
purpose of data transfer is very difficult to achieve, because the wifi is not available
at all the places.
