The document discusses a "5 Pen Technology" system called P-ISM, which was developed in 2003 and includes five pen-like devices: a CPU pen, camera pen, virtual keyboard, projector pen, and communication pen. P-ISM allows users to perform desktop computer functions by projecting a virtual keyboard and screen onto any flat surface. It uses electronic perception technology and wireless connectivity to link the pens together and to the internet. The system was an early concept for portable, connected computing using pen-based inputs.

4. History
 Pen style personal networking gadget created in 2003, by Tokyo-based Japanese technology
company NEC (Nippon Electric Company ).
 P-ISM(Pen-style Personal Networking Gadget Package) was first featured at the 2003 ITU
Telecom world held in Geneva, Switzerland.
 The P-ISM system was based on “Electronic Perception Technology" produced by the San
Jose, California, firm of Canesta

5. 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.

6. 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

7. 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.

8. P-ISM package including five gadget
 CPU Pen.
 Camera Pen.
 Virtual Keyboard .
 Projector Pen.
 Communication Pen.

9. “Pen-style Personal Networking Gadget Package”
P-ISM is a gadget package including five
functions:
CPU Pen
CAMERA
VIRTUAL KEYBOARD
VISUAL OUTPUT
A PHONE

11. 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.

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

13. Communication Pen
Uses Bluetooth Technology & Wi-Fi technology.
 Exchange information with wireless connection.
Connected to internet through cellular phone function.

14. Communication Pen
Very effective because we can able to connect whenever we need without having wires.
Bluetooth is a packet-based protocol.

15. Virtual Keyboard
 Virtual Keyboard is a new gadget.
 It emits laser on desk which gives an alternative input mechanism.
 Based of Electronic Perception Technology and 3D IR Sensor Technology.
 Reduce the risk of keystroke logging.

16. Virtual Keyboard
 Reduce the risk of password theft from malicious “Spyware ” and “Trojan Programs ”..

17. 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

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

19. Digital Camera
 Digital camera in the shape of pen .
 Useful in video recording, video conferencing, simply it is
called as web cam.

20. 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.
 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.
