This document describes a Pen-style Personal Networking Gadget called P-ISM that was created in 2003 by a Japanese technology company. P-ISM uses five connected pens that function as a portable computing device: a CPU pen, communication pen, projector pen, virtual keyboard pen, and camera pen. The pens connect via short-range wireless technology and can also connect to the internet. The document outlines the history of P-ISM, provides block diagrams of its design, describes the functions of each pen, discusses the benefits and limitations of the technology, and concludes by envisioning future enhancements.

3. INTRODUCTION
The design concept uses five
pens was to make a computer.
Include Gadgets are:-
1. CPU pen
2. Communication pen
3. Projector pen
4. Virtual Keyboard
5. Camera pen

4. These pens are connected with one
another through short-range wireless
technology.
This whole set is also connected to the
internet.
All the five pens rest in a holding block.

5. HISTORY
P-ISM is a Pen-style Personal Networking Gadget.
It was created in 2003 by Japanese Technology
Company NEC.
The designer of 5-pen technology is Trou Ichihash.

7. FUNCTIONS PERFORMED BY 5-PENS

8. CPU PEN
The functionality of the CPU is done by
one of the pen.
It is also known as computing engine.
Dual Core processor is used.
Works with windows operating
 system.

9. COMMUNICATING PEN
They exchange the information with the
help of Bluetooth (wireless connection).
The whole set is also connected to the
internet. It uses Wi-Fi technology.
This device is having a earpiece also.

10. PROJECTOR PEN
Monitor is LED Projector.
Size is A4 or adjustable.
Resolution capacity is
1024*768 approx.
It gives more clarity and good
picture.

11. VIRTUAL KEYBOARD
 Virtual laser keyboard is a new
gadget.
 It emits laser on the desk and it
looks like a keyboard with Qwerty
arrangement.
 Uses laser beam to generate full
size perfect keyboard.

12. CAMERA PEN
This pen is useful in video recording , video
conferencing. We call it as web cam.
It is a 360 degrees visual communication device.
We can do group to group communication with it.
It has an electronic image sensor.
 With the help of this pen we can also perform
scanning.
It is also connected with other devices through
Bluetooth.

13. BATTERY
Is the most important part in the portable type of
computers.
Usually batteries are small in size and work for
a long time.
It comes with a battery life of 6+ (i.e 6 days) and
for normal use it can be used for 2 weeks.

15. MERITS
 P-ISM is portable and feasible.
 It makes use of Wi-Fi technology.
 This technology can be used by everyone in very
efficient manner.
 It will take less internal and external space.
 It’s easier to handle and use.
 We can re-size the screen to our preference.

16. DEMERITS
Some prototypes in this are currently unclear.
This gadget is very costly.
It can be misplaced very
easily.
 It is touch screen.
The pens are small, could
lose them.

17. CONCLUSION
We have visualised the connection between the latest
technology and the human, in the form of pen. We can
say that communicating devices are getting smaller day
by day. This was just an example and we expect more
enhancement in this technology in coming years.
