History Introduction Working Of P-ISM Block Diagram Of P-ism Functions Of Pens Pros & Cons Conclusion Contents :
History “Pen-style Personal Networking Gadget" created in 2003 by Japanese technology company NEC. Its designer Tour Ichihash. P-ISM was first featured at the 2003 ITU Telecom world held in Geneva, Switzerland. NEC Company displayed a conceptual $30,000 prototype of P-ISM Tour Ichihash
Introduction The P-ISM system was based on “electronic perception tech nology”. P-ISMs are computers in the shape of different P-ISMSs are connected with a wireless technology. Whole set is connect ed with cellular phone function. P-ISM is a gadget package including five functions: i. A computing engine-CPU Pen ii. Virtual keyboard, iii. A very small projector, iv. Camera Scanner and v. communication device.
What is Electronic Perception Techn ology(EPT) ? Electronic Perception Technology (EPT) is a low-cost, single- chip imagining technology. 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 and distinguish objects from one another.
Working Of P-ISM P-ISMs are connected with one an other through short-range wireless technology. This "pen sort of instrument" produces both the monitor as well as the keyboard on any flat surfac es. The whole set is also connected to the Internet through the cellular phone.
Block Diagram Of P-ISM
CPU Pen The functionality of CPU is done by one of the pens. It is also known as ‘Computing Engine’. Dual core processor is used It works with ‘Windows OS’.
. The control unit direct the entire computer system Operation of a CPU include 4 steps : ● Fetch ● Decode ● Execute ● Write back CPU Pen
Communication Pen P-ISMs are connected with one another through short -range wireless technology. The whole set is also connected to the Internet throu gh the cellular phone function. They are connected through Tri-wireless modes (Blue tooth, 802.11B/G, and Cellular) which are made small and kept in a small pen like device.
Connectivity 802.11B/G and Bluetooth: Bluetooth is widely used because we can able to transfer data or make connections without wires. They are used at the frequency band of 2.4 GHz Bluetooth mechanism is used for exchanging signal status information between two devices.
LED Projector Monitor is LED projector. Size is A4. Resolution of 1024*768 approx. It gives good quality and good pictures.
LED Projector(Contd..) Led projector is a device that receives a video signal and projects the correspond ing image on a projection screen using a lens system. A video projector, also known as a digital projector, may be built into a cabinet with a rear projector screen( rear projection television, or RPTV) to form a single unifi ed displaydevice, now popular for “home theater” applications.
The Virtual Laser Keyboard (VKB) is the ultimate new gadget. It emits LASER on desk. Uses LASER beam to generate full-sized perfect keyboard. A virtual keyboard is a software component that allows a user to enter characters. Virtual keyboards may be used in some cases to reduce the risk of keystroke logging. Virtual keyboard
Virtual keyboards are commonly used as an on scree n input method in devices with no physical keyboard, where there is no room for one, such as a pocket computer, personal digital assistant (PDA) tablet computer or touch screen equipped mobile phone. It is common for the user to input text by tapping a virtual keyboard built into the operating System of th e device. Virtual keyboards are also used as features of emulat ion software for systems that have fewer buttons than a computer keyboard would have. Virtual keyboard
It is useful in video recording, video conferencing. It is simply called as Web Cam. It is connected with other devices through Bluetooth. Easily portable. It is a 360-Degree Visual Communication Device. Digital Camera
Three main methods of capturing the image o Single shot o Multi shot o Scanning Types of digital cameras o Compacts digital camera o Bridge camera o Mirror less interchangeable lens camera o Resolution is limited by a image sensor. Digital Camera
The most important part in the portable type of computer is its battery. Usually batteries must be small in size and work for longer time. It comes with a battery life of 6+ (i.e. 6 Days). For normal use it can be used for 2 weeks. Battery
The types of battery used here is lithium ion battery. The storage device is of the type tubular holographic which is capable of storing. The use of lithium ion battery in this gadget will reduce energy density, durability and cost factor. Battery
Forthcoming computer Portable Feasible Ubiquitous computing is done Wi-Fi Technology Carry within our pockets Pros of P-ISM
Low storage capacity It is very expensive Battery back-up is less Cons of P-ISM
