5 PEN TECHNOLOGY GUIDED BY: BY: SHAVETA TATWANI PRASHANT KUMAR ASST. 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.
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
• 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)
• 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 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
• 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.
