  • 1. 5 Pen Pc Technology Seminar by K.PriyaKeerthana
  • 2. CONTENTS History Introduction 5 functions Block Diagram Merits Demerits Conclusion
  • 3. History  Pen style personal networking gadget created in 2003, by Tokyo-based Japanese technology company NEC.  P-ISM was first featured at the 2003 ITU Telecom world held in Geneva, Switzerland.  The P-ISM system was based on "low- cost electronic perception technology" produced by the San Jose, California, firm of Canesta
  • 4. Designer of P-ISM 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. He also wanted a product that you could touch and feel. Further, the intent is to allow for an office anywhere.
  • 5. IntroductionP-ISM - Pen-style Personal Networking Gadget Package This pen sort of instruments produces both the soft-output as well asthe Virtual keyboard on any flat surfaces from where you can carry outfunctions you would normally do on your desktop computer. It is based on Electronic perception technology. P-ISM’s are connected with one another through short-range wirelesstechnology The whole set is also connected to the Internet through the cellularphone function
  • 6. What is ElectronicPerception Technology ?  Electronic Perception Technology (EPT) is a low-cost, single-chip imagining technology .  One of the first applications is a “virtual keyboard”.  EPT systems can accurately determine brightness and distinguish objects from one another.  Current EPT keyboards can sense up to 400 characters per minute.
  • 7. P-ISM package includingfive gadget CPU Pen. Camera Pen. Virtual Keyboard . Projector Pen. Communication Pen.
  • 8. Block diagram of pentechnology
  • 9. 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.  There are four steps that nearly all CPUs use in their operation: fetch, decode, execute, and write back.
  • 10. .  The control unit of the CPU contains circuitry that uses electrical signals to direct the entire computer system to carry out, stored program instructions.
  • 11. Communication Pen Wireless Bluetooth Technology.  Exchange information with wireless connection. Connected to internet through cellular phone function. Uses Wi-Fi technology
  • 12. . Very effective because we can able to connect whenever we need without having wires. Bluetooth is a packet-based protocol with a master-slave structure.
  • 13. Virtual Keyboard  Virtual Keyboard is a new gadget.  It emits laser on desk which gives an alternative input mechanism.  Based of Electronic Perception Technology.  Reduce the risk of keystroke logging.
  • 14. .  Reduce the risk of password theft from malicious “Spyware ” and “Trojan Programs ”..
  • 15. LED Projector The role of monitor is taken by LED Projector which projectson the screen. The size of the projector is of A4 size. Resolution capacity of 1024 x 768. Thus it is gives more clarity and good picture
  • 16.  A video projector is a device that receives a video signal andprojects the corresponding image on a projection screen using a lenssystem.
  • 17. Digital Camera Digital camera in the shape of pen . Useful in video recording, video conferencing, simply it is called as webcam. Types of digital camera Compact Digital Camera Bridge Camera Mirror less Interchangeable Camera
  • 18. .  Three main methods of capturing the image Single shot Multi shot Scanning
  • 19. Battery  It is the most important part in portable type of computers.  The type of battery used here is lithium ion battery.  Usually batteries are small in size and work for a long time.  It comes with a battery life of 6+ (i.e. 6days).  For normal use it can be used for 2 weeks.
  • 20. Battery(cont.) The storage device is of the type tubular holographic which is capable of storing. lithium ion battery in this gadget will reduce energy density, durability and cost factor.
  • 21. Advantages of P-ISM  Portable  Feasible  Wi-Fi technology  Based on Electronic Perception Technology
  • 22. Disadvantages of P-ISM Positioning is more important to use it to up to optimumlevel. Keyboard concept is not new. Currently unclear. Gadget is very costly
  • 23. 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.
  • 24. Thank you
