"Pen-style Personal Networking Gadget" created in 2003 by Japanese technology company NEC. Its designer is the Ichihash Tour. P-ISM was first presented at the 2003 ITUTelecom world held in Geneva, Switzerland.
"5 pen technology" is a recent discovery in the field of pen computing. Pen computing is a field that describes the computer as the user interface that makes use of the pen as devices that will be convenient to use as compared to contemporary systems (such as laptops, etc.). They are used to provide functions of a CPU, a projector, a virtual keyboard, a camera and communication functions of a mobile phone. All 5 pens are connected to each other via wireless technology preferably Bluetooth ie 802.11 BG. The whole pen 5 technology system is connected to the internet via the cell phone pen pen.5 PC technology is also known as P-ISM is Personal Penstyle Networking gadget package.
The continuous advancement of technologies has led to many changes in the field of information technology and communication. The connection between the last technology and the human one has been visualized in pen form. The design concept here makes use of five different pens to create a computer. One pen works as a camera, another as a CPU pen, one projects the visual output including the screen, another creates a virtual keyboard and the fifth pen is a communicator that functions as a mobile phone. All this set of pens rests on a retention block that recharges the batteries and maintains mass storage and these pens communicate wirelessly via Bluetooth. Therefore, P-ISM provides a good overview of what the future holds in the field of technology.
