This document summarizes a seminar presentation on the 5 Pen PC technology. The 5 Pen PC package includes pens for CPU functions, camera, virtual keyboard, projection, and communication. Each pen has a specific function like computing, wireless connectivity, input, display, or imaging. The technology is based on electronic perception that allows objects to be sensed. Some advantages are portability, feasibility, and WiFi connectivity. Disadvantages include needing precise positioning and high cost. The conclusion is that this represents new compact communication devices, and more developments in this area can be expected.

3. History
 Pen style personal networking gadget created in 2003,
by Tokyo-based Japanese technology company NEC.
 P-ISM was first featured at the 2003 ITU Telecom world
held in Geneva, Switzerland.
 The P-ISM system was based on "low-
cost electronic perception technology" produced by the San
Jose, California, firm of Canesta

4. Designer of P-ISM
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.

5. Introduction
P-ISM - Pen-style Personal Networking Gadget Package
 This 'pen sort of instruments' produces both the soft-output as well as
the Virtual keyboard on any flat surfaces from where you can carry out
functions you would normally do on your desktop computer.
 It is based on Electronic perception technology.
 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

6. What is Electronic
Perception Technology ?
 Electronic Perception Technology (EPT) is a low-cost, single-chip
imagining technology .
 One of the first applications is a “virtual keyboard”.
 EPT systems can accurately determine brightness and distinguish
objects from one another.
 Current EPT keyboards can sense up to 400 characters per
minute.

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.
 There are four steps that nearly all CPUs use in their
operation: fetch, decode, execute, and write back.

10. .
 The control unit of the CPU contains circuitry that uses electrical
signals to direct the entire computer system to carry out, stored
program instructions.

11. Communication Pen
Wireless Bluetooth Technology.
 Exchange information with wireless connection.
Connected to internet through cellular phone function.
Uses Wi-Fi technology

12. .
Very effective because we can able to connect whenever we
need without having wires.
Bluetooth is a packet-based protocol with a master-slave
structure.

13. Virtual Keyboard
 Virtual Keyboard is a new gadget.
 It emits laser on desk which gives an alternative input
mechanism.
 Based of Electronic Perception Technology.
 Reduce the risk of keystroke logging.

14. .
 Reduce the risk of password theft from malicious “Spyware ”
and “Trojan Programs ”..

15. 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.
 Resolution capacity of 1024 x 768.
 Thus it is gives more clarity and good picture

16.  A video projector is a device that receives a video signal and
projects the corresponding image on a projection screen using a lens
system.

17. Digital Camera
 Digital camera in the shape of pen .
 Useful in video recording, video conferencing, simply it is called as web
cam.
 Types of digital camera
Compact Digital Camera
Bridge Camera
Mirror less Interchangeable Camera

18. .
 Three main methods of capturing the
image
Single shot
Multi shot
Scanning

19. Battery
 It is the most important part in portable type of computers.
 The type of battery used here is lithium ion battery.
 Usually batteries are small in size and work for a long time.
 It comes with a battery life of 6+ (i.e. 6days).
 For normal use it can be used for 2 weeks.

20. Battery(cont.)
The storage device is of the type tubular holographic which is capable of
storing.
lithium ion battery in this gadget will reduce energy density, durability and
cost factor.

21. Advantages of P-ISM
 Portable
 Feasible
 Wi-Fi technology
 Based on Electronic
Perception Technology

22. Disadvantages of P-ISM
 Positioning is more important to use it to up to optimum
level.
 Keyboard concept is not new.
 Currently unclear.
 Gadget is very costly

23. Conclusion
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.
