History
• “Pen-style Personal Networking Gadget"
created in 2003 by Japanese technology
company NEC.
• Its designer Tour Ichihash.
•
P-ISM was first featured at the 2003
ITU Telecom world held in Geneva,
Switzerland.
• NEC Company displayed a conceptual
$30,000 prototype of P-ISM
Tour Ichihash
Introduction

The P-ISM system was based on “electronic perception
technology”.

P-ISMs are computers in the shape of different P-ISMSs
are connected with a wireless technology. Whole set is
connected with cellular phone function.

P-ISM is a gadget package including five functions:
i. A computing engine-CPU Pen
ii. Virtual keyboard,
iii. A very small projector,
iv. Camera Scanner and
v. communication device.
What is Electronic Perception Techn
ology(EPT) ?
• Electronic Perception Technology (EPT) is a low-cost,
single-chip imagining technology.
• One of the first applications is a "virtual keyboard”.
• Current EPT keyboards can sense up to 400 characters per
minute.
•
EPT systems can accurately determine brightness and
distinguish objects from one another.
Working Of P-ISM

P-ISMs are connected with one
another through short-range wir
eless technology.

This "pen sort of instrument"
produces both the monitor as w
ell as the keyboard on any flat s
urfaces.

The whole set is also connected
to the
Internet through the cell
ular phone.

CPU Pen

The functionality of CPU is done by one of the
pens.

It is also known as ‘Computing Engine’.

Dual core processor is used

It works with ‘Windows OS’.
CPU. Pen
The control unit direct the entire
computer system
Operation of a CPU include 4 steps :
● Fetch
● Decode
● Execute
● Write back
Communication Pen

P-ISMs are connected with one another through shortrange wireless technology.

The whole set is also connected to the Internet through
the cellular phone function.

They are connected through Tri-wireless modes (Bluet
ooth, 802.11B/G, and Cellular) which are made small
and kept in a small pen like device.
Connectivity 802.11B/G and Bluetooth:

Bluetooth is widely used because we can able
to transfer data or make connections without wi
res.

They are used at the frequency band
of
2.4 GHz

Bluetooth mechanism is used for exchanging s
ignal status information between two devices.
LED Projector

Monitor is LED projector.

Size is A4.

Resolution of 1024*768 approx.

It gives good quality and good pictures.
LED Projector(Contd..)

Led projector is a device that receives a v
ideo signal and projects the correspondin
g image on a projection screen using a le
ns system.

A video projector, also known as a digital
projector, may be built into a cabinet with
a
rear projector screen( rear projection t
elevision, or RPTV) to form a single unified
displaydevice, now popular for “home the
ater” applications.
Virtual keyboard

The Virtual Laser Keyboard (VKB) is the ultimate new
ga
dget.

It emits LASER on desk.

Uses LASER beam to generate full-sized perfect keyboard.

A virtual keyboard is a software component that allows a u
ser to enter characters.

Virtual keyboards may be used in some cases to reduce
e risk of keystroke logging.
th
Virtual keyboard

Virtual keyboards are commonly used as an on screen
input method in devices with no physical keyboard,
here there is no room for one, such as a pocket
mputer, personal digital assistant (PDA) tablet
w
co
com
puter or touch screen equipped mobile phone.

It is common for the user to input text by tapping a
v
irtual keyboard built into the operating System of the d
evice.

Virtual keyboards are also used as features of emulatio
n software for systems that have fewer buttons
n a computer keyboard would have.
tha
Virtual keyboard

Features of virtual keyboard are:


Sound
Connection

Intensity

Timeouts

Sensitivity

Auto_repeat
Example
Digital Camera


It is useful in video recording, video conferencing.
It is simply called as Web Cam.

It is connected with other devices through Bluetooth.

Easily portable.

It is a 360-Degree Visual Communication Device.
Digital Camera
Three main methods of capturing the image
o
Single shot
o
Multi shot
o
Scanning
Types of digital cameras
o
Compacts digital camera
o
Bridge camera
o
Mirror less interchangeable lens camera
o
Resolution is limited by a image sensor.
Battery

The most important part in the portable type of computer is it
s battery.

Usually batteries must be small in size and work for longer ti
me.

It comes with a battery life of 6+ (i.e. 6 Days).

For normal use it can be used for 2 weeks.
Battery


The types of battery used here is lithium ion battery.
The storage device is of the type tubular holographic which is capable
of storing.

The use of lithium ion battery in this gadget will reduce energy density, d
urability and cost factor.
Pros of P-ISM

Forthcoming computer

Portable

Feasible

Ubiquitous computing is done

Wi-Fi Technology

Carry within our pockets
Cons of P-ISM

Low storage capacity

It is very expensive

Battery back-up is less
Conclusion
Say, "Good-bye Laptops!"
