This 21st century is considered to be as new world era. In the modern world communication technology is rapidly increasing. And ofcourse

omputer is the main communication machine used. Since the time computer has been invented scientists and engineers have been trying

making it more and more compact. Some of the results we have found in the form of Mobiles I-pods and I-phones have replaced the

laptops or desktops to an extent. But the scientist is now making effort on makint it more compact even then mobile.  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 full-blown computer. It

is a computer broken apart into pieces, each the size of a pen. The screen and keyboard are projected onto surfaces.

Before proceeding to detail of this new inventions following technology need to be known. P-ISM (“Pen-style Personal Networking Gadget

Package”), which is nothing but the new discovery, which is under developing, stage by NEC Corporation.P-ISMs are connected with one

another through short-range wireless technology. The whole set is also connected to the Internet through the cellular phone function. They

are connected through Tri-wireless modes (Bluetooth, 802.11B/G, and Cellular) that are made small and kept in a small pen like

device.Bluetooth phenomenon is used for exchanging signal status information between two devices. This techniques do not require

communication between the two devices (such as Bluetooth’s Adaptive Frequency Hopping), the most efficient and comprehensive solution

for the most serious problems can be accomplished by silicon vendors. They can implement information exchange capabilities within the

designs of the Bluetooth.

Similarly, 5 Pen PC Technology is a gadget package including five functions: a pen-style cellular phone with a handwriting data input

function, virtual keyboard, a very small projector, camera scanner, and personal ID key with cashless pass function. 5 Pen PC Technology

are connected with one another through short-range wireless technology and the whole set is connected to the Internet through the cellular

phone function. This personal gadget in a minimalist pen style enables the ultimate ubiquitous computing.

Brief decription of each component:

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 and works with windows operating system.

Communication Pen:

Communication pen uses the P-ISMs phenomenon. They are connected through Tri-wireless modes (Blue tooth, 802.11B/G, and Cellular)

which are made small and kept in a small pen like device.

LED Projector:

LED Projector works as the monitor. LED projector projects on the screen. It gives more clarity and good picture as it gives the approximate

resolution capacity of 1024 X 768.The size of the projector is of A4 size.

Digital Camera:

Surprisingly, we also have digital camera in the shape of pen. This pen is useful in video recording, video conferencing.It can also be

interpreted as web cam. It is also connected with other devices through Blue tooth. The major advantage are:

It is small which is easily portable.

It is a 360-Degree Visual Communication Device.

Virtual Keyboard:

The Virtual Laser Keyboard (VKB) is the new gadget for PC users. The VKB emits laser on to the desk where it looks like the keyboard

having QWERTY arrangement of keys i.e., it uses a laser beam to generate a full-size perfectly operating laser keyboard that smoothly

connects to of PC and Most of the handheld devices including PDA’s or tablet PC’s.

Features of virtual keyboards are:

Connection: Connection to the appropriate Laptop/PC port

Intensity: Intensity of the projected Virtual Keyboard

VKB settings can be changed by Sound: A direction technology based on an optical recognition mechanism enables the user to tap on the projected key images, while producing real tapping sounds.

Controllable Virtual Keyboard sound effects (key clicks). VKB’s adaptable technology studies the user’s finger movements to interpret and record keystrokes. Because the virtual keyboard is an image projected by light, it disappears completely when not in use.

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.

Compatible: It is more compatible and it did not require any practice to operate but you must have strong fingers to tap.

Battery:

It is the most essential component in the portable type of computer. An ideal batteries must be small in size and work for longer time. It

comes with a battery life of 6+.If we talk about its usage, it can be used for 2 weeks.

Advantage of this 5 pen pc technology:

It is Portable i.e can be carried

It is Feasible

Ultimate ubiquitous

Support WiFi technology

Pens produces both the monitor as well as the keyboard on any flat surfaces from where you can carry out functions.

Disadvantages:

Positioning is more important to use it to up to optimum level.

keyboard concept is not new.

It is currently unclear
