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

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.

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

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.

P-ISM package including five gadget

CPU Pen.

Camera Pen.

Virtual Keyboard .

Projector Pen.

Communication Pen.

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.

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

Communication Pen

Wireless Bluetooth Technology.

Exchange information with wireless

connection.

Connected to internet through cellular

phone function.

Uses Wi-Fi technology

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.

Virtual KeyboardVirtual 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.

Reduce the risk of password theft from

malicious “Spy ware ” and “Trojan

Programs ”..

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

A video projector is a device that receives a

video signal and projects the corresponding

image on a projection screen using a lens

system.

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

Three main methods of capturing the

image

Single shot

Multi shot

Scanning

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.

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.

Advantages of P-ISM

Portable

Feasible

Wi-Fi technology

Based on Electronic

Perception Technology 

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

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.
