This document describes a 5 pen pc technology called P-ISM. P-ISM consists of 5 functions: a CPU pen, camera, virtual keyboard, visual output, and cellular phone. It uses various wireless technologies like Bluetooth and WiFi to connect multiple pens together and to the internet. The pens allow users to project a keyboard and monitor onto any flat surface and use it like a portable computer. While portable and allowing ubiquitous computing, challenges remain regarding its cost, battery life, and keyboard design.

by Japanese technology company NEC.
 Its designer Tour Ichihash.
 P-ISM was first featured at the 2003 ITUTelecom world
held in Geneva, Switzerland.

4. Look closely and guess what they could
be...
 P-ISM (“Pen-style
Personal Networking
Gadget Package”).
 Connected With A
Wireless Technology.
 Whole Set Is Connected
To Internet Through
Cellular Phone Function.

5.  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.

6. “Pen-style P ersonal Networking Gadget P ackage”

9. 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.

10. Continued….
 The control unit direct the entire computer system.
 Operation of a CPU include 4 steps :
 Fetch
 Decode
 Execute
 Write back
 The performance or speed depends on factors
 Clock rate
 IPC
 IPS

11. Communication Pen
 P-ISMs are connected with
one another through short-
range wireless technology.
 They are connected through
Tri-wireless modes like Blue
tooth, 802.11B/G, and
Cellular.

12. Continued….
 Bluetooth provides a secure way to connect and
exchange information between devices
 Connected to internet through cellular phone
function.
 Uses Wi -Fi technology.
 Exchange information with wireless connection

13. LED Projector
 Monitor is LED Projector.
 Size is A4.
 Resolution capacity
is1024*768 approx.
 It gives more clarity and
good picture.

14. Continued….
 Projection technologies used are:
 CRT projector using cathode ray tubes.
 LCD projector using LCD light gates.
 LCoS projector using Liquid crystal on silicon.
 The types of LED display are:
 conventional (using discrete LEDs) .
 surface-mounted device (SMD) panels.

15. Virtual Keyboard
 Virtual laser keyboard is a
new gadget.
 It emits laser on desk.
 Uses laser beam to
generate full_size perfect
keyboard.

16. Continued….
 Features of virtual keyboard are:
 Sound
 Connection

devices.
 portable.
 360 degree visual
communication device.

18. Continued….
 Types of digital cameras
 Compacts digital camera
 Bridge camera
 Mirrorless interchangeable lens camera
 Resolution is limited by a image sensor

19. 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).
 For normal use it can be used for 2 weeks.

20. Merits
 Portable
 Feasible
 Ubiquitous computing is done
 Wi_Fi technology

21. Demerits
• Currently un clear
• Cost
• Battery
• Keyboard concept is not
new
• Positioning is main

22. 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.
 The communication devices are becoming smaller and
compact. This is only an example for the start of this new
technology. We can expect more such developments in the
future.
