This document describes a 5 pen personal computer (5 pen PC) technology developed in 2003. The 5 pen PC breaks a computer into 5 pen-sized components connected wirelessly: a CPU pen, camera pen, virtual keyboard pen, projector pen, and communication pen. All components can rest in a base block that charges them. The technology allows for portable ubiquitous computing on any flat surface by projecting a keyboard and monitor. However, questions remain about its commercial availability due to high costs.

3. INTRODUCTION
5 pen pc shortly called as P-ISM
(“Pen-style Personal Networking
Gadget Package”) is an electronic
perception technology in which a
computer is broken apart into pieces
each having a size of a pen and
a function of its own. P-ISMs are
connected with a wireless technology
. Whole set is connected with cellular
phone function.

4. HISTORY
"Pen-style Personal
Networking Gadget" created
in 2003 by Japanese
technology company NCE.
Its designer is Tour Ichihash.
P-ISM was first featured at
the 2003 ITU Telecom world
held in Geneva, Switzerland.

5. ELECTRONIC PERCEPTION TECHNOLOGY
EPT is a low-cost , single-chip
imagining technology that enables electronic
components to form a 3-D map of their
surroundings and see what their user willing to do.
Current EPT keyboards can sense up to 400
characters per minute.

8. OVERVIEW

9. CPU PEN
 It is also known as computing engine.
 Dual Core processor is used.
 Works with windows operating system.
 The control unit of the cpu generates electrical
signals to direct other pens to execute the
instructions of a program in sequence.

10. COMMUNICATION PEN
Exchange information
using wireless Bluetooth
technology.
Connected to internet
through cellular phone
function.
Uses Wi-Fi technology.

11. VIRTUAL KEYBOARD
 Uses laser beam to generate full size perfect keyboard.
 It is a software component that allows a user to enter
characters.
 Virtual keyboards may be used in some cases to reduce
the risk of keystroke logging.
 Features of virtual keyboard are: Sound , Connection
,Intensity , Timeouts , Sensitivity , Auto repeat

12. PROJECTOR PEN
 LED Projector projects the
monitor on a screen.
 Size of the monitor is A4.
 Resolution capacity is1024
*768 approx.
 It gives more clarity and go
od picture.

13. CAMERA PEN
 It is a digital camera in the
shape of a pen.
 It is useful in video recording,
video conferencing, simply it
is called as web cam.
 It is also connected with
other devices through
Bluetooth.
 It is a 360 degrees visual
communication device.

14. BASE BLOCK
 All five pens can rest in a
holding block which recharges
the batteries and holds the
mass storage.
 The types of battery used here
is lithium ion battery.
 It comes with a battery life of
6+ (i.e. 6days).
 For normal use it can be used
for 2 weeks.
 The use of lithium ion battery
in this gadget will reduce
energy density, durability and
cost factor

15. ADVANTAGES
Portable.
Ubiquitous
computing.
Wi-Fi technology.
Feasible.
Mobility.

16. DISADVANTAGES
Currently unclear.
Easily misplaced.
The gadget is very costly the consumer
cannot afford to purchase them.
Positioning is main.

17. SECURITY
E-fingerprinting makes the gadget more secure,
which allows only owner to activate the pc. So even
if we loose it, no one else can access the gadget.
Virtual keyboards are used to reduce the risk of
keystroke logging.
The use of on screen keyboard can increase the risk
of password disclosure.

18. FUTURE SCOPE
The 5 Pen Pc Technology project started in the
year 2003.However, the information about its
release is not yet made public. Whether it will
be available for the public use is still a question,
because of its excessive price of 30,000$. The
prototype developed by the company proves
that the creation of such complex technology is
feasible, but because of lack of information
about its recent developments, it is unclear
what the company’s intentions are about this
technology.

19. CONCLUSION
This 'pen sort of instrument' produces both the
monitor as well as the keyboard on any flat
surfaces from where you can carry out
functions you would normally do on your
desktop computer.
