The document discusses a "5 Pen Technology" system developed in 2003 that allowed a computer to fit in a pencil case. The system included 5 pens: a CPU pen, communication pen, virtual keyboard, camera pen, and projector pen. The pens were connected wirelessly and to the internet using cellular functions. The virtual keyboard projected a keyboard onto surfaces using electronic perception technology. While portable and innovative, the system was also expensive and had unclear development status. The technology showed future possibilities for compact wireless devices.

2. 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

4. 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.

5. 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.”

6. 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.

7. 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.

8. P-ISM package consists of five pens:
CPU pen
Communication pen
Virtual Keyboard
Camera pen
Projector pen

9. CPU PEN

10. 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.

11. COMMUNICATION PEN

12. 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.

13. VIRTUAL KEYBOARD (VKB)

14. 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.

15. DIGITAL CAMERA

16. 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

17. LED PROJECTOR

18. 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.

19. 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.

20. ADVANTAGES
• Portable
• Feasible
• Makes use of Wi-Fi technology
• Based on Electronic Perception Technology
• Small size

21. DISADVANTAGES
• Cost factor
• Keyboard concept is not new (Lumio Inc.)
• Can be easily misplaced
• Currently unclear

22. 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.
