5 pen technology presentation
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.

- 1. 5 PEN TECHNOLOGY GUIDEDBY: BY: SHAVETA TATWANI PRASHANT KUMAR ASST. PROFESSOR 00410402712 (CSE/IT) CSE
- 2. FROM THE VERYBEGINNING • 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 “5PEN 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 isa 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 consistsof five pens: CPU pen Communication pen Virtual Keyboard Camera pen Projector pen

- 10. CPU PEN • Functionalityof 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.

- 12. COMMUNICATION PEN • Exchangesinformation 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.
- 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.
- 16. DIGITAL CAMERA • Digitalcamera 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.
- 18. LED PROJECTOR • Roleof 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 devicesare 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.
