5 PEN TECHNOLOGYGUIDED BY: BY:SHAVETA TATWANI PRASHANT KUMARASST. PROFESSOR 00410402712(CSE/IT) CSE

FROM THE VERY BEGINNING

• First computer invented - the ENIAC (1943)

• Modern computers based on integrated circuits

• Today, very compact table computers with the most popular being the IPad (9.1 inch and weighing about 700 grams)

• Now, imagine having a computer that will fit into your pencil case

HISTORY OF “5 PEN TECHNOLOGY”

• Pen Style Personal Networking Gadget (P-ISM) -created in 2003 by Tokyo based Japanese company, NEC

• First featured at 2003 ITU Telecom world – Geneva, Switzerland

• P-ISM system – based on “Electronic Perception Technology” – pioneered by Canesta Inc., San Jose, California.

Designer of P-ISM – Toru Ichihashi

He 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. I wanted a product that you could touch and feel.”

• “Further, the intent is to allow for an office anywhere.”

INTRODUCTION

• P-ISM is a gadget package includes five pens: a CPU pen, communication pen with a cellular phone function, virtual keyboard, a very small projector, and a camera.

• Connected with one another through short-range wireless technology.

• Connected to the Internet through the cellular phone function.

• Based on Electronic Perception Technology.

ELECTRONIC PERCEPTION TECHNOLOGY

• Electronic Perception Technology (EPT) is a low-cost, single-chip imagining technology that enables electronic components to form a 3-D map of their surroundings and see what their users are doing.

• 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.

• EPT systems can determine depth.

P-ISM package consists of five pens:CPU penCommunication penVirtual KeyboardCamera penProjector pen

CPU PEN

CPU PEN

• Functionality of the CPU - done by one of the pen also known as computing engine.

• Consists of dual core processor embedded in it

• Works with WINDOWS operating system.

• Contains circuitry that uses electrical signals to direct the entire computer system to carry out program instructions.

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

COMMUNICATION PEN

COMMUNICATION PEN

• Exchanges information using wireless communication

• Uses Bluetooth Technology

• Uses Wi-Fi Technology

• Connected to internet using Cellular phone functions

• Very effective due to absence or any kind of wiring

• Provides ear piece as well as pointer using pressure sensing.

VIRTUAL KEYBOARD (VKB)

VIRTUAL KEYBOARD (VKB)

• It emits laser beam on to the desk to generate a full-size perfectly operating laser keyboard.

• It uses 3-D imaging (EPT).

• It reduces the risk of keystroke logging.

• It avoids password theft from viruses.

DIGITAL CAMERA

DIGITAL CAMERA

• Digital camera or the webcam is in the shape of a pen

• Useful in video recording and video conferencing, etc.

• Its three main capturing methods:

• Single shot

• Multi shot

• Scanning

LED PROJECTOR

LED PROJECTOR

• Role of monitor is taken by LED Projector which projects on the screen

• Size of the projector - A4

• Approximate resolution capacity is 1024 x 768

• Video projector is a device that receives a video signal and projects the corresponding image on a projection screen using a lens system.

BATTERY AND STORAGE

• Present in the base of the P-ISM.

• Most important part in portable type of computer is battery and storage capacity.

• Type of battery used here is lithium ion battery which can last for about 2 weeks of normal use.

• Use of lithium ion battery in this gadget will reduce energy density, durability and cost factor.

• Storage device is of the type of tubular holographic which can have a capacity of up to a terabyte with that small size.

ADVANTAGES

• Portable

• Feasible

• Makes use of Wi-Fi technology

• Based on Electronic Perception Technology

• Small size

DISADVANTAGES

• Cost factor

• Keyboard concept is not new (Lumio Inc.)

• Can be easily misplaced

• Currently unclear

CONCLUSION

The communication devices are becoming smaller and compact.

This technology is just an example of what we’ll be using in the future.

This is just a start and we can expect such more developments in the upcoming years.
