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.
