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 P personal Networking Gadget P ackage”
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 with a master-slave structure.

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.

21. 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.

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

23. 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

24. 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.
