1. Introduction

• Just as the name suggests, this technology is comprised of 5 major components.

• It utilizes Bluetooth & internet in order to communicate.

• 5 pen pc shortly called as P-ISM (Pen-style Personal Networking Gadget Package).

• Whole Set Is Connected To Internet Through Cellular Phone Function

• It is based on Low Cost Electronic perception technology (EPT).

2. History

• 5 Pen technology created in 2003 by Japanese technology company NEC.

• Its designer is Tour Ichihash.

• P-ISM was first featured at the ‘ITU Telecom world 2003 ’ held in Geneva, Switzerland.

3.1 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.

• It is also applicable to android and Linux operating systems.

7

• There are four steps that nearly all CPUs use in their operation: fetch, decode, execute, and write back.

• Fetch involves retrieving an information from memory.

• After the execution write back operation simply writes back the results to memory.

8

3.2 Communication Pen• It offer technologies like:

1. Bluetooth

2. WLAN

3. Cellular phone function.

• Bluetooth mechanism is used for exchanging signal status information between two devices.

• Uses Wireless Local Area Networks (802.11)802.11 a

802.11 b/g/n

802.11 ac

9

• Connected to internet through cellular phone function.

• Its cellular network function offer a number of advantages over other solutions.

1. Increased Capacity

2. Reduced power use

3. Large coverage area

4. Reduced interference from other signals

3.3 Projector Pen

• The role of monitor is taken by LED Projector which projects on the screen.

• Depending on how far we are from a flat surface, this can be either adequate or very clear.

• The size of the projector is of A4 size.

• Thus it is gives more clarity and good picture

11

• Common display resolutions for a portable projector include

SVGA (800x600 pixels)

XGA (1024x768 pixels)

720p (1280x720 pixels)

1080p (1920x1080 pixels)

• Out of these Projector pen provides Resolution capacity of 1024 x 768.

12

3.4 Virtual Keyboard• This component works much like the

projected screen.

• It emits laser on desk which gives an alternative input mechanism.

• It analyses what we are typing according to the co-ordinates of the location.

• Not only this connect to our pc, but also our tablet, smartphone and much more devices.

13

3.5 Digital Camera• Probably the most important part of 5

pen applications.

• The camera is very small and lodges itself within the pen style gadget.

• It is useful in video recording , video conferencing simply as a webcam.

• Connected with other devices using same Bluetooth technology.

• Portable.

• 360 degree visual communication device.

14

Camera Pen

3.6 Battery & Mass storage• Is the most important part in the portable

type of computers.

• Usually batteries should be small in size and work for a long time.

• The type of battery used here is lithium ion battery.

• It comes with a battery life of 6+ (i.e. 6 days).

• For normal use it can be used for 2 weeks.

• Also the base includes mass storage for storing data's.

5. Merits

• It is convenient to use because of its portability. (Small and Compact)

• It support wireless technologies like Bluetooth and Wi-Fi

• Excellent battery backup.

• Touch and feel technology

17

6. Demerits

• It works on wireless technologies and therefore it has limitations of range.

• Gadget is very costly

• One of the components can be easily misplaced

• Projection surface should be flat for optimum usage.

18

7. 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.
