This document describes a 5 Pen PC technology that allows a computer's functions to be broken up into separate pen-sized devices that can be combined. Each pen has a specific function like a CPU, camera, projector, or virtual keyboard. When connected wirelessly using Bluetooth or WiFi, the pens allow users to access computing functions anywhere by projecting a keyboard and screen onto surfaces. The technology aims to provide ubiquitous computing in a portable form factor.

7. INTRODUCTION
There are computers in the shape of different pens
each having a function of its own and when combined
together give us the usage of a full­blown computer.
It is a computer broken apart into pieces, each the
size of a pen.

8. CONTINUE............
P­ISM is a gadget package including five functions: a
pen­style cellular phone with a handwriting data input
function, virtual keyboard, a very small projector, camera
scanner, and personal ID key with cashless pass function.
This 'pen sort of instrument' produces both the monitor
as well as the keyboard on any flat surfaces from where
you can carry out functions you would normally do on
your desktop computer.

P-ISM is a gadget package including five functions:
● CUP PEN
● CAMERA
● VIRTUAL KEYBOARD
● VISUAL OUTPUT
● APHONE

Operation of a CPU include 4 steps :
● Fetch
● Decode
● Execute
● Write back

22. ● led projector is a device that receives a video
signal and projects the corresponding image on a
projection screen using a lens system.
● A video projector, also known as a digital
projector, may be built into a cabinet with a rear­
projector screen( rear projection television, or
RPTV) to form a single unified display device,
now popular for “home theater” applications.

23. Virtual Keyboard
● Virtual laser keyboard is a new gadget.
● It emits laser on desk.
● Uses laser beam to generate full_size perfect
keyboard.
● A virtual keyboard is a software component that allows a
user to enter characters.
● Virtual keyboards may be used in some cases to reduce
the risk of keystroke logging.

24. Virtual keyboards are commonly used as an on-screen input
method in devices with no physical keyboard, where there is
no room for one, such as a pocket computer, personal digital
assistant (PDA) tablet computer or touch screen equipped
mobile phone.
It is common for the user to input text by tapping a virtual
keyboard built into the operating System of the device.
Virtual keyboards are also used as features of emulation
software for systems that have fewer buttons than a computer
keyboard would have.

25. Continue...........
Features of virtual keyboard are:
– Sound
– Connection
– Intensity
– Timeouts
– Sensitivity
– Auto_repeat

26. VKB settings can be changed by Sound:
Controllable Virtual Keyboard sound effects (key clicks)
Connection: Connection to the appropriate
Laptop/PC port.
Intensity: Intensity of the projected Virtual
Keyboard
Timeouts: Coordinated timeouts to conserve the
Virtual Keyboard’s battery life
Sensitivity: Adjustable sensitivity of the Virtual
Keyboard
Auto-repeat: Allows the VKB to automatically repeat
a key based on prescribed parameters.

28. Digital Camera
We also have digital camera in the shape of pen.
It is useful in video recording, video conferencing,
simply it is called as web cam.
It is also connected with other devices through Blue
tooth.
It is a 360 degrees visual communication device.

29. MAJOR ADVANTAGE OF DIGITAL CAMERA
It is small which is easily portable.
It is a 360-Degree Visual Communication Device.

Types of digital cameras
● Compacts digital camera
● Bridge camera
● Mirror less interchangeable lens
camera
Resolution is limited by a image sensor

32. BATTERY
Is the most important part in the portable type of
computers.
Usually batteries are small in size and work for a
long time.
It comes with a battery life of 6+ (i.e 6 days).
For normal use it can be used for 2 weeks.

33. ● 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, durability and cost
factor.

34. Merits of 5 Pen PC’s
1. Portable
2. Ubiquitous computing
3. Wi-Fi technology
4. Feasible

35. Demerits of 5 Pen PC's
1) Positioning
2)Cost
3)Battery
4)keyboard concept is not new

36. Conclusion
This 'pen sort of instrument' produces both
the monitor as well as the keyboard on any
flat surfaces from where you can carry out
functions you would normally do on your
desktop computer.

37. 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.
